Follow the important precautions below. Compatible Disk Type • 3.5” 2DD and 2HD type floppy disks can be used. A blank 2HD floppy disk has been included with your instrument for you to record your performances. ■ Inserting/Ejecting Floppy Disks To insert a floppy disk into the disk drive: • Hold the disk so that the label of the disk is facing upward and the sliding shutter is facing forward, towards the disk slot. Carefully insert the disk into the slot, slowly pushing it all the way in until it clicks into place and the eject button pops out. To eject a floppy disk: • Before ejecting a floppy disk make sure that the floppy disk drive is not in operation (the DISK IN USE indicator should be off.) • Press the eject button slowly as far as it will go; the disk will automatically pop out. When the disk is fully ejected, carefully remove it by hand. 4 • Never attempt to remove the disk or turn the power off during recording, reading and playing back. Doing so can damage the disk and possibly the disk drive. • If the eject button is pressed too quickly, or if it is not pressed in as far as it will go, the disk may not eject properly. The eject button may become stuck in a half-pressed position with the disk extending from the drive slot by only a few millimeters. If this happens, do not attempt to pull out the partially ejected disk, since using force in this situation can damage the disk drive mechanism or the floppy disk. To remove a partially ejected disk, try pressing the eject button once again, or push the disk back into the slot and then repeat the eject procedure. • Be sure to remove the floppy disk from the disk drive before turning off the power. A floppy disk left in the drive for extended periods can easily pick up dust and dirt that can cause data read and write errors. Cleaning the Disk Drive Read/Write Head • Clean the read/write head regularly. This instrument employs a precision magnetic read/write head which, after an extended period of use, will pick up a layer of magnetic particles from the disks used that will eventually cause read and write errors. • To maintain the disk drive in optimum working order Yamaha recommends that you use a commercially-available dry-type head cleaning disk to clean the head about once a month. Ask your Yamaha dealer about the availability of proper head-cleaning disks. Never insert anything but floppy disks into the disk drive. Other objects may cause damage to the disk drive or floppy disks.  Handling the Floppy Disk Drive(FDD) and Floppy Disk ■ About the Floppy Disks To protect your data (Write-protect Tab): To handle floppy disks with care: • To prevent accidental erasure of important data, slide the disk’s writeprotect tab to the “protect” position (tab open). • Do not place heavy objects on a disk or bend or apply pressure to the disk in any way. Always keep floppy disks in their protective cases when they are not in use. • Do not expose the disk to direct sunlight, extremely high or low temperatures, or excessive humidity, dust or liquids. • Do not open the sliding shutter and touch the exposed surface of the floppy disk inside. • Do not expose the disk to magnetic fields, such as those produced by televisions, speakers, motors, etc., since magnetic fields can partially or completely erase data on the disk, rendering it unreadable. • Never use a floppy disk with a deformed shutter or housing. • Do not attach anything other than the provided labels to a floppy disk. Also make sure that labels are attached in the proper location. Write protected Write enabled Data backup • For maximum data security Yamaha recommends that you keep two copies of important data on separate floppy disks. This gives you a backup if one disk is lost or damaged. To make a backup disk use the Backup function on page 54. YAMAHA is not responsible for damage caused by improper handling or operation. YAMAHA provides no guarantee against disk damage. 5  * Apple and Macintosh are the registered trademarks of Apple Computer, Incorporated. * Atari is the registered trademark of Atari Corporation. * IBM PC/AT is the registered trademark of International Business Machines Corporation. * MS-DOS is the registered trademark of Microsoft Corporation. * The company names and product names in this owner’s manual are the trademarks or registered trademarks of their respective companies. 6  CONGRATULATIONS! You are now the proud owner of a Yamaha MDF3 MIDI Data Filer. This compact data storage unit is capable of storing bulk data from nearly any MIDI-equipped synthesizer, tone generator, or sequencer on convenient 3.5" 2HD/2DD floppy disks. The MDF3 is also able to record and play back sequencer data in realtime, a feature which makes it handy for use as a portable sequencer. To put the MDF3 to work, you will need to connect it to at least one other MIDI device. If you own the Yamaha QX3 or a MIDIequipped personal computer with a 3.5" disk drive, the MDF3 will also be able to read the data from disks you create with these devices, for maximum flexibility and convenience in data management. This Owner’s Manual has been written for easy reference, and includes helpful advice for a wide range of applications. In order to take full advantage of the many capabilities of your MDF3, we urge you to read through the manual carefully first, then keep it on hand for future reference. FEATURES • MIDI data recorder capability The MDF3 is able to receive, store, and re-transmit MIDI System Exclusive data from nearly any MIDI instrument with bulk data transmission capability, including devices made by manufacturers other than Yamaha. The MDF3 can also read and transmit bulk data files created by the Yamaha MDF2 Data Filer and the QX3 sequencer in that device’s MDR mode. • Sequencer capability The MDF3 is capable of recording sequence data to disk, and playing back this data in realtime. It can also play back data files written by other MIDI devices using Standard MIDI File format 0/1, as well as ESEQ sequence files created by the Yamaha QX3, etc. (You can also play back the MDF2’s SEQ data). Other convenient playback functions allow you to play a program of up to 99 sequence data files in a specified order, and to play back files repeatedly in an endless loop. • Ample data storage capacity The MDF3 can store as many as 99 bulk or sequence files — on each 2HD/2DD floppy disk. If necessary, a single bulk or sequence data file can occupy the disk’s total capacity of roughly 1,200/600 kilobytes of data. In sequencer mode, this corresponds to approximately 150,000/75,000 notes’ worth of sequence data. 7  ABOUT THIS MANUAL This Owner’s Manual introduces the MDF3’s functions in an order close to that in which you are most likely to be using them. As you read through the manual, you will soon learn how the MDF3 works; and you will find, in addition, a number of hints on how you can put its features to use. Nearly every operation in this manual is described as a series of simple steps, often including diagrams that make the procedure easy to follow.

These terms are frequently used in describing the functions of MIDI equipment. MIDI 10 An abbreviation for Musical Instrument Digital Interface, which is the name of an international standard providing for the communication of data between electronic musical instruments. MIDI allows musical instruments such as synthesizers and drum machines to communicate with each other, and to be controlled by sequencers or computers. MIDI device Any piece of electronic equipment capable of receiving or sending data in a manner that complies with the MIDI standard. This term is often applied to synthesizers, tone generators, rhythm machines, and sequencers; however, it also includes a variety of peripheral devices including signal processors and patch bays, not to mention MIDI data recorders such as the MDF3. MIDI data Data in a format that complies with the MIDI standard. MIDI data can be divided between two broad categories : sequence data and bulk data. sequence data The data used to record and play back music. Generally speaking, sequence data consists of note on and off messages, control change messages, and program change messages. In special cases, however, it may also include certain types of system exclusive data. bulk data Data transmitted in units known as blocks, usually for the purpose of storage or retrieval. Each MIDI device usually transmits bulk data in a unique format that distinguishes it from the bulk data of other devices; thus, it is also known by the name “system exclusive data”. Bulk data is usually not directly related to a musical performance; rather, it is used as a means for transferring large blocks of data, such as voice data, samples, or system setup data, between two MIDI devices. bulk dump A transmission of bulk data from one MIDI device to another.  Keywords for MDF3 operation The terms defined below are used throughout the manual to describe functions peculiar to the MDF3. The same words are frequently used in describing other MIDI devices, as well; but keep in mind that in many cases the actual function in question may differ considerably from that performed by the MDF3. file A position on a disk where data is stored and assigned a name. The MDF3 is capable of managing up to 99 files on a single disk. The number of files that can be created on any given disk is physically limited by the size of the files and the disk’s capacity of approximately 1,200 (MF2HD)/600 (MF2DD) kilobytes. file, it simultaneously reads data from the disk and outputs it via the MIDI OUT jack. SEQ mode The mode of operation in which the MDF3 is used to record and play back sequence data. SEQ data The contents of the file that is created when the MDF3 records sequence data. Such data is often referred to as “song data”. Strictly speaking, however, such a file can contain as many as several songs, or as little as a single phrase. MDR mode The mode of operation in which the MDF3 is used to receive and transmit MIDI bulk data. MDR data The contents of the data file that is created when the MDF3 receives bulk data from another MIDI device. recording reception Generally, the receiving by one MIDI device of MIDI data from another. In this manual, “reception” refers specifically to the MDF3’s reception of bulk data. The MDF3 automatically writes the bulk data it receives to disk as an MDR data file. The reception of MIDI sequence data. Recording is different from the reception of bulk data in that the data is received in realtime. The MDF3 automatically writes the sequence data it receives to disk as a SEQ data file. playback The transmission of sequence data from one MIDI device to another. Playback differs from the transmission of bulk data in that the sequence data is transmitted in realtime. When the MDF3 plays back a SEQ data file, it simultaneously reads data from the disk and outputs it via the MIDI OUT jack. transmission Generally speaking, the sending of data from one MIDI device to another. In this manual, “transmission” means specifically the transmission of MDR data by the MDF3. When the MDF3 transmits the contents of an MDR data 11  INTRODUCING THE MDF3 Front panel q w e r q MIDI LED 12 t y u i This LED lights when the MDF3 is receiving MIDI data. Note that it does not light when data is being transmitted, however. w LCD The LCD displays a variety of information to assist you in operating the MDF3. e Mode keys These keys allow you to switch between the MDF3’s four operating modes. The MDF3’s modes — MDR mode, SEQ mode, JOB mode, and UTILITY mode — are outlined in the MDF3 Mode Overview on page 20. r CURSOR keys These keys move the cursor in the LCD to the left or right. They can also be used to fast forward or rewind a file during playback in SEQ mode. t FILE DATA keys These keys are used to select a file ( in the MDR and SEQ modes) or a function (in the JOB and UTILITY modes). They can also be used to change the tempo during playback in SEQ mode. y REC key This key is used in combination with the START/ STOP key to begin the reception/recording of data in MDR and SEQ modes. u PAUSE key This key pauses the recording or playback of a file in progress in SEQ mode .It can also be used in combination with the REC key to tell the MDF3 to standby for recording in this mode. i START/STOP key This key is used to start and stop reception/ recording or transmission/playback in MDR and SEQ modes. It is also used to execute functions in the JOB and UTILITY modes.  Rear Panel Side Panel !4 !6 o !0 !1 !2 !3 o MIDI OUT This jack outputs MIDI data. !0 MIDI IN Received MIDI data is input via this jack. !1 FOOT SW This jack enables START/STOP control by pressing the foot switch (optional Yamaha FC4, FC5, etc.) if it is connected. !22 DC IN The DC plug of an optional AC power adapter (Yamaha PA-3B) can be connected here. !3 POWER This switch turns the power to the MDF3 on and off. !5 !4 Disk Drive This 3.5" disk drive is capable of accepting both 2HD and 2DD floppy disks. !5 Eject button This button ejects the floppy disk from the disk drive. !6 Disk Access LED This LED lights when data is being written to or read from a disk.

The MDF3 can be powered by the Yamaha PA-3B power adaptor, which is available for purchase separately. Under normal operating conditions, the MDF3 can be operated continuously for approximately three hours using a fresh set of batteries. Before you connect the adaptor, check to make sure that the POWER switch on the rear panel is turned off. Plug the round end of the adaptor cord into the DC IN jack on the back panel of the MDF3, then plug the adaptor itself into an AC outlet. Before you begin to insert the batteries, check to make sure that the POWER switch on the rear panel is turned off. Then, place six size “AA” alkaline batteries in the battery compartment located on the underside of the unit. + – + – – + – + PA-3B + DC IN – + – Make sure that the batteries are oriented properly. The correct orientation is indicated by the markings on the inside of the compartment. Caution: When the batteries run down, replace them with a complete set of six new batteries. NEVER mix old and new batteries. Caution: Be sure to use a power adaptor that is suited to the voltage in your locale. Do not use an adaptor other than PA-3B. Any other AC adaptor using different voltage can damage the MDF3. Unplug the AC power adaptor when not using the instrument, or during electrical storms. 14 Do not use different types of batteries (e.g. alkaline and manganese) at the same time. Be sure to remove the batteries from the MDF3 when you will not being using it for an extended period of time. If you leave batteries in the unit during extended periods of disuse, you run the risk of damage due to corrosion.  Connecting a MIDI Device Turning the Power On You need only one MIDI cable to connect the MDF3 to another MIDI device. To turn on the MDF3, simply press the POWER switch on the rear panel. When you will be using the MDF3 to receive or record data, plug one end of the cable into the MIDI IN jack on the MDF3 back panel, and the other end into the MIDI OUT jack of the other device. The message “YAMAHA MDF3” will appear in the LCD for a few moments. Then, if there is no disk in the disk drive, this message will be replaced by the following display: MIDI cable MIDI IN MIDI OUT extemal MIDI device (keyboard, sequencer, etc) MDF3 !~~~~No~disk~~~~ Insert the 3.5" 2HD/2DD floppy disk that came with your MDF3 in the disk drive. Be sure to insert the disk with the label side facing up and the arrow pointing toward the disk drive. To transmit or play back data from the MDF3 , simply reverse these connections. MIDI cable MIDI OUT MIDI IN extemal MIDI device (keyboard, sequencer, etc) Push the disk in gently, until you hear it settle into the drive with a click. MDF3 If you have two MIDI cables, you can connect the MIDI IN jack of each device to the MIDI OUT jack of the other. This convenient arrangement will allow you to avoid the repeated changing of MIDI cable connections. Note: The MDF3 is capable of using 3.5" 2HD/2DD floppy disks. Please do not try to use any other type of disk. 15  Formatting a Floppy Disk Before the MDF3 can create files on a new disk, it must prepare the disk to accept the data using a procedure known as “formatting”. Follow the steps below to format the floppy disk that came with your MDF3. 1. Enter the UTILITY mode. 2. Select ”05: Format” Press the UTIL key. The LED above the key will light. Press the FILE DATA [+] key four times. The following message will appear in the LCD. 05:~~~~~~~Format ~å 3. Press the START/STOP key. The LED above the key will flash, and the following message will appear in the LCD: 4. Insert a disk. If you have not already done so, insert the 2HD/2DD disk to be formatted in the disk drive. Format~disk Note: If you format a disk that has been used before, any data it contains will be erased. Make absolutely sure that a disk does not contain any important data before you format it. 16  5. Press the START/STOP key. 6. Format another disk. 7. Exit the function. The LED above the key will light steadily, and the LCD will display a message telling you what percentage of the disk has been formatted. If you wish to format another disk at this point, eject the disk and insert a new one. Then press the START/STOP key to begin formatting once more. When you’re done formatting disks, press any mode key (MDR, SEQ, JOB, or UTIL) to exit the “Format” function. Formatting~~~93% It should take approximately 70 seconds to format a single floppy disk. When the disk has been completely formatted, the START/STOP LED will begin to flash again, and the “Format disk” message will reappear. 17  Handling Floppy Disks The 3.5" 2HD/2DD floppy disk is a reliable and convenient medium for data storage, capable of holding large amounts of data in a small package. The disk itself is a delicate piece of magnetic film, which is protected from dust and dirt by a hard plastic cover and a shutter. This design is capable of preserving your data against most contingencies. However, for the greatest reliability, you should observe a few basic cautions when handling your disks. • Use 2HD/2DD disks. The MDF3 is not designed to handle disks meeting other specifications. • Never remove a disk from the disk drive while the disk access LED is lit. Doing so can damage the floppy disk or the disk drive. • Avoid touching the shutter of a disk. Never open the shutter and touch the actual disk surface. • Avoid placing disks close to speakers, televisions, magnets, or other objects with magnetic fields. Even weak magnetic fields can damage or erase the data on a disk. • Do not leave your disks in cars or other locations where they may be exposed to extreme heat or cold. • Do not leave your disks in places where they may be exposed to condensation or extremely high humidity. • Avoid using or storing disks in places where they may be exposed to large amounts of dust or dirt. Follow these cautions scrupulously. Improper handling can render a disk useless, and may cause damage to the MDF3’s disk drive as well. 18  Protecting the data on a disk If you turn a disk face down, you will find a small plastic tab in the lower right corner. This tab is a write-protect switch that you can use to prevent the accidental loss of valuable data. When this tab is in the up position (so the window is closed), the MDF3 will be able to read and write data to the disk normally. To protect the data on a disk, push the tab down so that the window is open. The MDF3 will be able to read the data on the disk as usual. However, if you try to receive or record data using the disk, the MDF3 will display an error message telling you that the disk is write-protected. You will see the same message if you try to format a write-protected disk or change the data it contains using one of the UTILITY mode functions. !~~Disk~protect Note: To protect disks against accidental erasure, it is a good idea to set the protect tab down and keep the disk in a safe place. You also might consider making a backup copy of the disk using the UTILITY mode ”Backup” function. Finally, clear labeling of disk contents is a simple but effective way to prevent the accidental loss of valuable data. 19  MDF3 MODE OVERVIEW Now that you’ve formatted a floppy disk, you’re ready to start using the MDF3. The overview below summarizes the use of each of the MDF3’s four modes, and shows you how to access the JOB and UTILITY mode functions. 20 MDR mode (page 23) SEQ mode (page 31) This mode lets you receive bulk data from a MIDI device and save it to disk as an MDR data file. In this mode the MDF3 can also transmit the contents of MDR files it creates, as well as bulk data files created by the Yamaha MDF2 and the QX3 in MDR mode. This mode lets you record sequence data as standard MIDI files. In this mode, the MDF3 can also play back the SEQ data files it creates (You can also play back the MDF2’s SEQ data files), as well as Yamaha ESEQ data files and standard MIDI files created by other devices. JOB mode (page 39) UTILITY mode (page 47) This mode lets you play back SEQ data files repeatedly, or in a programmed order. It also allows you to set the sequence data playback tempo, and to enable or disable the transmission and reception of MIDI sync and system control messages. The UTILITY mode lets you rename, delete, copy, and append files. It also allows you to format or copy disks, and to check the amount of space remaining on a disk. Hint: In the JOB and UTILITY modes, you can use the FILE DATA keys to select a function, and the START/STOP key to execute the function you’ve selected.  JOB mode functions 01:~~Repeat~play 02:~~~~Prog~play 03:~Record~tempo 04:~~~~Sync~mode 05:~MIDI~control UTILITY mode functions This function lets you repeatedly play back one or more SEQ data files in an endless loop. (page 40) This function lets you create a program of SEQ data files to be played back in a specified order. (page 41) This function allows you to change the playback tempo that is recorded for a sequence data file. (page 43) This function determines whether the MDF3 runs on its internal clock, or in sync with an external MIDI clock. (page 44) This function enables or disables the transmission and reception of MIDI realtime control messages (i.e., START, CONTINUE, and STOP messages), as well as the transmission of MIDI clock signals.

This function lets you change the names of MDR or SEQ data files which have been saved to disk. (page 49) This function lets you delete unneeded MDR or SEQ data files from a disk. (page 51) This function creates a copy of a file, or appends the data of one file to the end of another file. (page 52) This function lets you copy the entire contents of one disk to another disk. (page 54) This function is used to format new floppy disks for use by the MDF3. (page 56) This function displays information about a disk, including the amount of disk space that has been used, the amount of available space remaining, the number of files that have been used, and their respective sizes. (page 57) 21  22  MDR MODE MDR In its MIDI data recorder (MDR) mode, the MDF3 is capable of receiving MIDI bulk data from nearly any MIDI device and saving it to disk as an MDR data file. It can then transmit this data back to the device that originated it, or to any other device capable of accepting the data, at any time. Receiving bulk data The bulk data reception function is used to receive bulk data sent from another MIDI device. The MDF3 automatically writes the bulk data it receives to disk as an MDR data file using Standard MIDI File format 0. You can save up to 99 MDR data files on a single disk. Transmitting bulk data The bulk data transmission function lets the MDF3 output the data which it has previously saved as an MDR data file to a MIDI device capable of receiving it. The MDF3 is also able to transmit the data from files created by the Yamaha MDF2 and the QX3 in that device’s MDR mode. 23  Receiving Bulk Data 1. Check your MIDI connections. 2. Enter MDR mode. 3.

The MDF3 will end transmission after it has sent the current data block. 28  Reception Transmission MDR file size: On a newly formatted 2HD disk, a single MDR file formats: In addition to its own files, the MDF3 MDR data file can hold up to about 1,200 kilobytes of data. When using a disk that already contains several files, check the amount of available space on the disk (page 57) before you try to receive the bulk data. Bulk data blocks: The MDF3 recognizes bulk data blocks by their header (System Exclusive status: F0H) and footer (End of Exclusive: F7H) values. Block intervals: When the MDF3 creates MDR files, it also records timing data at 10 millisecond intervals. If the interval between any two data blocks exceeds one second, the MDF3 will record it as one second. When receiving data from a MIDI device that will require intervals greater than one second between blocks when you attempt to transmit the data back to the device, record the bulk data in SEQ mode. (Refer to “Recording bulk data” on page 38) MDR Notes on MDR Data Reception and Transmission is capable of transmitting bulk data files which other devices save to disk using Standard MIDI File format 0. Moreover, it can transmit MDR bulk data files written by the Yamaha MDF2 and the QX3 in that device’s MDR mode. It distinguishes between these two types of files by checking the header of each file before it begins transmitting the data in the file. Transmitting QX3 data: When the MDF3 transmits MDR data files written to a disk by the QX3, it will automatically insert a 100 millisecond interval after every data block, as well as after each kilobyte of data (when a block is longer than one kilobyte). 29  30  SEQ MODE The following descriptions of the sequence data recording and playback procedures assume that you will be recording data output by a MIDI keyboard. Of course, you can use the same procedures to record sequence data played back by a sequencer, a personal computer, or the like. Recording Sequence Data SEQ When you record data in SEQ mode, the MDF3 automatically writes this data to disk as a SEQ data file using Standard MIDI File format 0. You can save up to 99 SEQ data files on a single disk. Playing Back Sequence Data The MDF3 can of course play back the files it records in SEQ mode. It can also play back files written by other devices using Standard MIDI File format 0 or 1, as well as sequence files written in the ESEQ format used by the QX3 and other Yamaha devices. You can also play back the MDF2’s SEQ data files. Note: If you will be using the MDF3 to play sequence files written by other devices, be sure to keep these files and your SEQ files on separate disks. If you mix SEQ files with other sequence files on a single disk, the MDF3 will display the names of only the SEQ files. (Please see ”The Standard MIDI File and ESEQ Formats” on page 58 for details.) 31  Recording Sequence Data 1. Check your MIDI connections. 2. Enter SEQ mode. 3. Select an empty file. The MIDI IN jack of the MDF3 should be connected to the MIDI OUT jack of the sending device. Press the SEQ key.

Hint: If you prefer, you can press the START/ STOP key instead of the PAUSE key to begin recording immediately. the PAUSE key. The MDF3 will begin recording again as soon as it receives any MIDI data (except bulk data), or if you press the PAUSE key once more. You can also resume recording by pressing the foot switch if it is connected. If you press the START/STOP key while the recording is paused, the recording will end and the data up to that point will be saved as a SEQ file. 33  6. End the recording. When you have finished recording data, press the START/STOP key again. The data you sent will be saved to the SEQ data file you selected, using the default file name “SONG_” followed by the file number. 03~SONGå03 Hint: If you would like to give the file another name, you can do so using the “Rename” function (page 49). 34  Playing Back Sequence Data 1. Check your MIDI connections. 2. Enter SEQ mode. 3. Select a file to transmit. The MIDI OUT jack of the MDF3 should be connected to the MIDI IN jack of the receiving device. Press the SEQ key.

Prepare the receiving device. 5. Start the playback. 6. Change the tempo. Prepare your keyboard or tone generator to receive the sequence data. The preparations to be made vary depending on the instrument, but may include the selection of MIDI channels and sound programs, the adjustment of pitch bend and modulation ranges, and so on. Refer to the appropriate operation manual to check the correct procedure. Press the START/STOP key. The MDF3 will begin to play back the sequence data file you’ve selected. While the file is playing, the LCD will indicate the elapsed performance time. You can use the FILE DATA keys to change the playback tempo while the file is playing. When you press one of the FILE DATA keys, the following display will appear. SONGå01~~~~00:34 SONGå01~~~~œ=120 file name performance time Note: When you press the START/STOP key, the MDF3 will hesitate for 1 – 15 seconds as it reads data from the disk before it begins to play back the data. If you need to start the playback with greater accuracy, press the PAUSE key immediately after pressing the START/STOP key and wait until the START/ STOP LED lights. The MDF3 will begin playing the file as soon as you press the PAUSE key a second time or press the foot switch if it is connected. 36 file name tempo Note: Sequence data files created by devices other than the MDF3 may include tempo change data that will alter the tempo regardless of the changes you make using the FILE DATA keys. Since the playback tempo is commonly recorded at the beginning of a file, you may find that the tempo will return to its original value if you play a file from the top after changing the tempo using the FILE DATA keys.  7. Advance, rewind, or pause the file. 8. Stop the playback. While the file is playing, you can use the CURSOR keys to fast forward or rewind the file. Also, you can press the PAUSE key to pause the playback temporarily. Playback will stop automatically when the MDF3 reaches the end of the file. If you want to stop the playback before the MDF3 comes to the end of the file, simply press the START/STOP key. SEQ rewind fast forward When playback ends, the name of the currently selected file will appear. 01~~~~~~SONGå01 Hint: Files can be played back repeatedly using the “Repeat play” function (page 40). If a disk contains more than one SEQ data file, the files can be played back in a specified order using the “Prog play” function (page 41). 37  Notes on SEQ Data Recording and Playback Recording Playback Record tempo: A default playback tempo of 120 beats SEQ file formats: In addition to its own SEQ files, the per minute is recorded for each SEQ data file. You can change the tempo before you begin recording using the Record Tempo function (page 43). MDF3 is capable of playing back sequence data files which other devices have written to disk using Standard MIDI File format 0 or 1, a format which is supported by a broad range of computer-based MIDI software. It is also capable of playing back ESEQ sequence data files created by the QX3 and other Yamaha products. (You can also play back the MDF2’s SEQ data files). Recording bulk data: Since the MDF3 records both bulk and sequence data as standard MIDI files, it is able to record bulk data as well as sequence data in SEQ mode. To record bulk data in SEQ mode, you must start the recording using the REC and START/STOP keys, rather than the REC and PAUSE keys. Also, if you pause the recording while the MIDI LED indicates that the MDF3 is receiving data, the PAUSE key will blink and the MDF3 will continue recording until it has finished receiving the current block. Finally, you must press the START/STOP key to stop recording manually. Otherwise, the MDF3 will continue recording even after the sending device has stopped sending data. 38 Using MDR and SEQ data: The SEQ data you record will play back flawlessly if the receiving instrument’s settings (such as its MIDI channel and program selections, volume setting, pitch bend and modulation ranges, and so on) are the same as they were when you recorded the data. If these settings are changed, however, the playback might not be quite what you expect. Of course, you could make a note of your settings and restore them manually each time you play back the file; but you can save yourself the trouble and make better use of your MDF3’s capabilities by sending them as a bulk dump to the MDF3, then transmitting this data back to the instrument before you play back the sequence data.  JOB MODE The five JOB mode functions are related to the recording and playback of sequence data files. They allow you to play back SEQ data files repeatedly, or in a programmed order; to change the playback tempo that is recorded to sequence data files; and to control how the MDF3 synchronizes recording and playback with other MIDI sequencers. Selecting a JOB mode function To use a JOB mode function, first press the JOB key, then use the FILE DATA keys to select the function. When the name of the desired function is displayed in the LCD, press the START/STOP key. 01:~~Repeat~play JOB Note that you must place a disk in the disk drive before you select “Repeat play” or “Prog play” in order to use these function. Exiting a JOB mode function When you have finished making settings using one of the JOB mode functions, you can exit the function by pressing any of the mode selection keys. 39  Repeating Playback The “Repeat play” function lets you play back one or more SEQ files repeatedly. This function could be used to practice a single song several times, or to create an endless loop of background music. 1. In JOB mode, select ”01: Repeat play”. 2. Select the desired setting. 3. Start playback. Use the FILE DATA keys to select one of the three possible repeat settings. Press the SEQ mode key and start playback. The MDF3 will repeatedly play a single song or all of the songs on the disk, depending on the setting you selected. 01:~~Repeat~play When you press the START/STOP key, the current repeat play setting will appear in the LCD. Repeat~=~~~~~~~1 ~~~~~~~~~~~~~~~å When you select “1”, the MDF3 will play the SEQ data file you select repeatedly. 40 Repeat~=~~~~~all ~~~~~~~~~~~~~~~å Repeat~=~~~~~off ~~~~~~~~~~~~~~~å Note: The “Repeat play” function is auto- This setting turns the repeat function off. matically set to “all” whenever you turn on power to the MDF3. When you play files with this setting, the MDF3 repeatedly plays all of the SEQ data files on the disk in numerical order. Hint: You can change the order in which “Repeat=all” plays songs by changing the SEQ file name extensions (see page 59 for details.) 01:~~~~~SONGå01  Creating a Playback Program The “Prog play” function lets you create a program of up to 99 SEQ files to be played back in a specified order. 1. In JOB mode, select “02: Prog play”. 02:~~~~Prog~play 2. Select a file. 3. Press the START/STOP key. Using the FILE DATA keys, select the song to be played for the currently displayed program step. Your setting for the step will be registered, and the display will change to the next step. Prog:01=01~SONGå Prog:02=..~..... When you press the START/STOP key, the following display will appear in the LCD. JOB Prog:01=..~..... program step file number file name 41  4. Program other steps. 5. Start playback. Repeat steps 2 and 3 as needed to program additional steps. Your program may contain up to 99 steps. When you’ve finished creating your program, press the SEQ mode key and start playback.

If the “Repeat play” function is set to “off”, however, the program will be played only once. will be erased when the MDF3 is turned off, or when you remove the disk from the disk drive.  Changing the Record Tempo The MDF3 automatically records sequence data at a default tempo of 120 beats per minute. The SEQ data files that you record will be played back at this default tempo unless you change the playback tempo using the FILE DATA keys. If you wish , you can use the “Record Tempo” function to set the tempo setting of a file before you start recording it. 1. In JOB mode, select “03: Record Tempo”. 03:~Record~Tempo 2. Select the desired tempo. 3. Start recording To increase the tempo, press the FILE DATA [+] key. To decrease it, press the FILE DATA [–] key. The tempo can be changed within a range from 30 to 250 beats per minute. When you begin recording data in SEQ mode, the tempo you set here will be recorded at the start of the file as the SEQ file’s playback tempo. When you press the START/STOP key, the current record tempo setting will appear in the LCD. JOB Rec~Tempo~~œ=123 Rec~Tempo~~œ=120 SONGå03~~~~00:00 Note: Whenever the MDF3’s power is turned Hint: When you record sequence data played back by a sequencer, you should set the record on, the record tempo value is automatically set to the default value of 120 beats per minute. tempo to a value equal to that used by the sequencer. When recording data from a keyboard or other digital instrument, you can use this function to record fast musical phrases that would otherwise be difficult or impossible to play. This can be done by setting a faster playback tempo. 43  Selecting a MIDI Sync Mode To synchronize the playback of the MDF3 with that of another MIDI sequencer, rhythm machine, or personal computer, it is not enough to merely set the same tempo value for the two devices. One device must be set to function as the master, while the other functions as a slave, synchronizing playback to the MIDI clock signal output by the master rather than its own internal clock. You can change the synchronization setting using the “Sync mode” function. 1. In JOB mode, select “04: Sync mode”. 2. Select the desired setting. 3. Exit the function. Using the FILE DATA keys, select either setting. Press any mode key (MDR, SEQ, JOB, or UTIL) to exit the function. 04:~~~~Sync~mode When you press the START/STOP key, the current sync mode setting will appear in the LCD. ~~~~~~Sync~=MIDI ~~~~~~~~~~~~~~~å ~~~~~~Sync~=~int ~~~~~~~~~~~~~~~å Note: Whenever the MDF3’s power is turned on, the sync mode is automatically set to the internal clock. 44 If you set the sync mode to “int.”, the MDF3 will ignore any clock signals output by other devices and run at the tempo set by its internal clock. If you select “MIDI”, the MDF3 will synchronize to an external clock signal, and ignore any tempo settings you have made. When you next begin recording or playback, the MDF3 will use the sync mode setting you have selected.  Enabling MIDI Control Messages The “MIDI control” function lets you enable or disable the MDF3’s transmission and reception of MIDI realtime system control (Start, Continue, and Stop) messages. The setting you make here combines with the sync mode setting described on the previous page to determine how MIDI devices control each other during playback. 1. In JOB mode, select “05: MIDI control”. 2. Select the desired setting. 3. Exit the function. Using the FILE DATA keys, select either setting. Press any mode key (MDR, SEQ, JOB, or UTIL) to exit the function. 05:~MIDI~control JOB When you press the START/STOP key, the current MIDI control setting will appear in the LCD. MIDI~Control=off ~~~~~~~~~~~~~~~å MIDI~Control=on ~~~~~~~~~~~~~~~å Note: Whenever the MDF3’s power is turned on, the MIDI control function will automatically be set to “on”. When the MIDI control function is turn on, the MDF3 will transmit and receive Start, Continue, and Stop messages. It will also transmit MIDI clock signals. When this function is turned off, the MDF3 will neither transmit nor receive the MIDI Start, Continue, or Stop messages; nor will it transmit MIDI clock signals. When you next begin recording or playback, the MDF3 will use the MIDI control setting you have selected. 45  Notes on MIDI Synchronization The MIDI clock of a sequencing device to be synchronized with the MDF3 must normally be set to a value opposite that of the MDF3. If you want the MDF3 to control the playback tempo, select the “int.” sync mode and set the other device to use the MIDI clock. If the other device is to be the master, reverse these settings. In either case, you should also use the “MIDI control” function to enable the MDF3’s transmission and reception of MIDI system control messages. When synchronizing the MDF3 to another device, both the “Sync mode” and “MIDI control” functions must be set to appropriate values. The possibilities for combining these settings are summarized in the table below. 04: Sync mode 05: MIDI control MDF3 operation MIDI on Functions as a slave device. int. on Functions as a master device. MIDI off Cannot be used. int. off Manual playback; no MIDI synchronization. Note: If an external sequencer or other device connected to the MDF3 retransmits the MIDI data it receives (using a MIDI echo function), avoid a looped MIDI connection or set the MDF3’s MIDI control function to “off”. Otherwise, the MDF3 may malfunction. 46  UTILITY MODE The UTILITY mode functions let you rename, delete, or copy the files on a disk; append files to one another; or copy the entire contents of one disk to another. Selecting a UTILITY mode function To use a UTILITY mode function, first press the UTIL key, then use the FILE DATA keys to select the function. When the name of the desired function is displayed in the LCD, press the START/STOP key. 01:~~~~~~~Rename Note: You must place a disk in the disk drive in order to use the “UTILITY mode” functions. Exiting a UTILITY mode function UTIL When you have finished using a UTILITY mode function, you can exit the function by pressing any of the mode selection keys. 47  File Names in UTILITY Mode In UTILITY mode, file names appear differently than in other modes. The letter “M” will appear before the file numbers of MDR data files: Nam:M01~MDRå01 file number file name SEQ data files, on the other hand, will be indicated by the letter “S”: Nam:S01~SONGå01 The files will be displayed in numerical order. The MDR files will appear first, and SEQ files will follow. 48 If there are no files on a disk, the following display will appear when you select a UTILITY mode function. Nam:xxx~xxxxxxxx ~~~~~~å Selected function Indicates there is no file When this display appears, you can not utilize any of the UTILITY mode functions.  Renaming Files You can give each MDR or SEQ file you create a unique name of up to eight characters. Doing so will make it much easier for you to select a desired file. 1. In UTILITY mode, select “01: Rename” 2. Select a file. 3. Move the cursor to the file name. Using the FILE DATA keys, select a file to rename. Press the CURSOR [>>] key to move the cursor to the file name area.

When the desires character appears, press a CURSOR key to move to the next letter. When you’ve finished changing the name, press the START/STOP key. The MDF3 will write the new name to disk. Nam:M03~~~TDRå03 ~~~~~~~~~~å Nam:M03~~~TDRå03 ~~~~~~~~~~~å Available characters: Hint: You can run through the options rapidly by holding down the FILE DATA keys. 50 Repeat steps 4 and 5 as needed until you have changed the entire name. You can now press the CURSOR [<<] key to move the cursor back to the file number area and select a new file to rename; or press any of the mode keys (MDR, SEQ, JOB, or UTIL) to exit the function.  Deleting Files The “Delete” function lets you remove unnecessary files from a floppy disk. 1. In UTILITY mode, select “02: Delete”. 2. Select a file. 3. Press the START/STOP key. Using the FILE DATA keys, select a file to delete. When you are sure of your selection, press the START/STOP key. The MDF3 will delete the file, and the name of the next file in order will appear in the LCD. 02:~~~~~~~Delete ~å When you press the START/STOP key, the name of the first file on the disk will appear in the LCD.

UTIL cursor Note: You can only delete files created on 51  Copying or Appending Files The “Append” function lets you copy files, or append files to each other. If you select two files which contain data as the source and destination files, the data from the source file will be appended to the end of the destination file. If you select an unused file as the destination file, the source file will be copied. (The copied file will be given the same name as the source file.) 1. In UTILITY mode, select ”03: Append”. 2. Select a source file. 3. Move the cursor to the right. Using the FILE DATA keys, select the file to be copied or appended. Press the CURSOR [>>] key to move the cursor to the destination file number.

You will not be allowed to append an MDR file to a SEQ file, or vice-versa. UTIL 4. Select a destination file. 53  Copying Disks It is always a good idea to make backup copies of disks containing valuable data. The “Backup” function helps you do this by copying all the data on one disk (which is known as the “source” disk) to another disk (which is called the “target”). 1. In UTILITY mode, select ”04: Backup”. 2. Insert the source disk. 3. Press the START/STOP key. Place the disk to be copied in the disk drive. The following display will appear as the MDF3 reads data from the source disk. 04:~~~~~~~Backup When you press the START/STOP key, the following message will appear in the LCD. Now~reading... After a few moments, the following message will appear. Insert~Source~! Insert~Target~! 54  4. Insert the target disk. 5. Press the START/STOP key. 6. Back up other disks. Remove the source disk from the disk drive, and insert a newly formatted disk. The following display will appear as the MDF3 writes data to the target disk. If you want to copy another disk, press the START/STOP button; or press the mode keys (MDR, SEQ, JOB, or UTIL) to exit the function. Hint: The MDF3 can copy approximately 100 kilobytes of data at one time. When you copy a disk containing a large amount of data, you will have to repeat steps 2 through 5 several times. Now~writing... After a few moments, the “Insert Source!” message will reappear. Repeat steps 2 through 5 until the completed message appears. If you have a personal computer with two disk drive capable of handling 3.5" 2HD/2DD floppy disks, you may find it easier to back up your MDF3 data disks using the computer! Note: Please use the same type of disks to back up your data. If you attempt to back up your data in 2HD disk to 2DD disk or vice versa, the “Bad Disk” message will appear and the backup will be rejected. UTIL Completed~! If you want to estimate the number of times you will have to exchange disks to complete the backup process, use the “Disk Info” function to check how much of the source disk has been used before you execute the function. 55  Formatting Disks As we explained earlier in this manual, a new floppy disk must be formatted before the MDF3 can use it to save data. 1. In UTILITY mode, select ”05: Format”. 2. Insert a disk. 3. Press the START/STOP key. Insert the disk to be formatted in the disk drive. The LED above the key will light steadily, and the LCD will display a message telling you what percentage of the disk has been formatted. The MDF3 will recognize the inserted floppy disk type (2HD or 2DD) and format it automatically in appropriate size, 1,440 kilobytes for 2HD and 720 kilobytes for 2DD. 05:~~~~~~~Format When you press the START/STOP key, the following message will appear in the LCD. Formatting~~~93% Format~disk 56 Note: If you format a disk that has been used before, any data it contains will be erased. Make absolutely sure that a disk does not contain any important data before you format it. When the disk has been formatted, the START/STOP LED will begin to flash again, and the “Format disk” message will reappear. You can repeat the process again to format another disk, or press any mode keys (MDR, SEQ, JOB, or UTIL) to exit the function.  Displaying Disk Information The “Disk info.” function lets you check the amount of available space remaining on a disk. It also displays other information such as the amount of disk space which has already been used, the number of files on the disk, and their respective sizes. 1.

There are actually two Standard MIDI File formats: Format 0 records all sequencer data for channels 1 through 16 as a single track, whereas format 1 provides for an unlimited number of tracks, each including data for one or more channels. The ESEQ format is a sequence file format particular to Yamaha products. This format is used by a number of popular Yamaha sequencing devices, such as the QX3 and the Clavinova CVP series. The MDF3 writes its SEQ data files using Standard MIDI File format 0. It is capable of playing back files written by other devices in the Standard MIDI File format 0 or 1, as long as they are stored on a disk which the MDF3 is capable of reading (MS-DOS 1,440 kilobytes (2HD) or 720 kilobytes (2DD)). Moreover, the MDF3 can play ESEQ sequence files while in SEQ mode. It distinguishes between standard MIDI files and ESEQ files by checking the file header. No conversion process is required to play back ESEQ files. Note: Files named such as “PIANODIR.FIL”, “MUSIC.DIR”, “NAME.MDA” included in the ESEQ disks are the setup files and cannot be played back. 58 If you will use the MDF3 to play sequence files recorded by other devices, be sure to keep these files and your MDF3 (or MDF2) SEQ files on separate disks. When you place a disk containing only non-SEQ files in the MDF3, it will display the full file name (including the extension) of each file. Should you mix SEQ files together with other sequence files on a single disk, however, the MDF3 will display the names of the SEQ files only, making it impossible to play the other files. Hence the need to keep SEQ files and non-SEQ files on separate disks. If you have a personal computer, you can trick the MDF3 into playing back ESEQ files (or standard MIDI files created by other devices) which you have saved on disks containing SEQ files. To do so, you must use your computer to change the file name extensions of the non-SEQ files. The method for accomplishing this is described in the following pages.  ADVANCED FILE MANAGEMENT TECHNIQUES Reading MDF3 Disks with a Computer The disks you format for use with the MDF3 are compatible with MS-DOS or PCDOS. This means that you can read the data from your MDF3 disks using an IBM PC/AT -compatible computer. Conversely, the MDF3 will be capable of reading data from 3.5" 2HD/2DD disks formatted by an IBM PC/AT. Hint: The Atari ST and Apple Macintosh are also capable of reading data from disks formatted by the MDF3. If you own a Macintosh, use a utility program such as PC Exchange, Apple File Exchange or DOS Mounter to read the data from your MDF3 disks. Try inserting an MDF3 disk into the disk drive of your PC, then display a directory of the disk’s contents. You will see a display something like the following: a>dir b: BE-BOP .X01 412 00-00-80 12:00 ROLLING .X02 533 00-00-80 12:00 HOME .B01 256 00-00-80 12:00 LIVE .B02 256 00-00-80 12:00 Note: The display somewhat varies depending on the computer’s operating system you are using. As you can see, each of the MDF3 file names is followed by a three-character “extension”. The MDF3 uses these extensions to organize the files on its disks. Extensions beginning with the letter “B” indicate that the file in question contains MDR data, whereas files bearing extensions beginning with the letter “X” contain SEQ data. The second two characters of each extension indicates the file number by which the MDF3 refers to the file. Thus, MDR data file number 01 would have the extension “.B01”, whereas SEQ data file number 01 would have the extension “.X01”. If you desire, you can use your computer to change these extensions. Doing so will make possible some “tricky” applications that you normally could not achieve using the MDF3 alone. Some examples are given on the next page. 59  Changing MDF3 File Name Extensions Here are a few examples of advanced techniques that become possible when you use a computer to change the extensions of your MDF3 files. Reordering songs Changing MDR files to SEQ files You will recall that when you set the “Repeat play” function to “all”, the MDF3 will play back each of the SEQ data files on a disk in order. Now, imagine that you have recorded a number of SEQ files to a disk, and suddenly decide you want to play the first and second files in the opposite order. The MDF3’s “Prog play” function is handy, so long as the synthesizer or tone generator that plays the data can use the same data setup for all of the songs. But you may find yourself in a situation where you wish you could transmit some bulk data to change the setup between files. You could change their order using the “Append” and “Delete” function; but this would be pretty troublesome. It would be much easier to simply insert the disk in your computer, change the extension of file 01 to “.X02”, and then change that of file 02 to “.X01”. When you put the disk back in the MDF3, the songs will have changed place just as if you had gone through the trouble of moving them. Of course, you can record the bulk data in SEQ mode; but you’d just as soon avoid the trouble this entails. Here’s good news: you can! Note: When you are renaming files, be careful not to give two or more files the same extension. If you do so, the MDF3 will only be able to read one of the files. 60 Sure, the MDF3 uses extensions to distinguish between MDR and SEQ data files; but this is only done as a matter of convenience. Since both types of data are recorded using Standard MIDI File format 0, there’s nothing wrong with changing the extension of an MDR file to “.X??” and playing it (or even appending it to another SEQ file) as though it were a song.  Mixing SEQ files and other files The MDF3 will display the names of ESEQ files or standard MIDI files written by other devices only when the disk they are on does not contain any files bearing the “.X??” extension. This makes it difficult, for example, to play a mixture of SEQ files and ESEQ files which have been saved on the same disk. Note: If you rename ESEQ files using the former method, you will be able to rename, copy, or delete them just as though they were SEQ files. If you try to use the “Append” function with such files, however, the MDF3 will display an error message. Fortunately, the MDF3 does not need the extensions to check the file format: it is capable of recognizing standard MIDI files and ESEQ files by checking their file headers. This means that you can fool the MDF3 into displaying the names of nonSEQ files in SEQ mode by changing their file name extensions to “.X??”. Remember, when you attempt this, that the second and third characters of the extension must be numbers, and that the extension must be different from those of all other SEQ files. There’s another way to trick the MDF3 into playing a mixture of SEQ files and other sequence files: you can rename all the SEQ files on the disk so that they have extensions other than “.X??” (e.g. “MID”). The MDF3 will then treat the disk as though it contained no SEQ files, displaying the full file name of every file. 61  APPLICATIONS A Portable MIDI Playback System An Extended MIDI System The MDF3, when used in combination with a compact MIDI tone generator module, can form the heart of a portable MIDI playback system. In such a system, you would slave the tone generator to the MDF3 in order to play back SEQ data files which you had recorded previously. In a complete MIDI system which already includes a personal computer or a sequencer. In such a system, you would normally use the master keyboard and the sequencer to record parts for each of the slave tone generators, then play the data back all at once. If you connect the MDF3 to the system as shown in the illustration below, you can use it to “capture” the completed performance as SEQ data in Standard MIDI File format. By adding a portable MIDI keyboard to this arrangement, you can add on-the-spot recording to the playback function of the basic system. Make your MIDI connections as seen in the diagrams below. For recording MIDI OUT MIDI IN MIDI THRU To do this, set the MDF3’s sync mode to “MIDI” and the MIDI control function to “on”. Then, press the REC and PAUSE keys. The MDF3 will wait for incoming sequence data to begin recording, then stop recording as soon as the sequencer transmits a MIDI Stop message.

Disk access errors: !~Play~only~disk !~~~~Memory~Full You have tried to record SEQ data to a disk containing only files created by other devices. As a result, the MDF3 has determined that the disk can only be used for playing back sequence data. The MDF3 has run out of disk space while recording SEQ data or receiving MDR data. The disk in the drive is write-protected, and so the MDF3 cannot receive, record, rename, copy, or delete data on that disk. If this message appears while recording SEQ data, the MDF3 will create a SEQ file containing the data that it receives before the error occurred. If the message appears while receiving MDR data, all of the received data will be lost. Move the write-protect tap up to enable the MDF3 to write data to the disk. Replace the disk with an empty disk, or one which contains sequence data files recorded by the MDF3 (or MDF2). Note: The MDF3 will only record sequence data to empty disks or disks that already contain files bearing the “.X??” extension. If all of the sequence files on a disk have extensions other than “.X??”, the MDF3 will decide that the disk can be used for sequence data playback only. Use a disk with enough available space. Check the amount of space remaining on a disk before receiving or recording. !~~Disk~protect !~~No~disk A floppy disk has not been inserted into the disk drive. Insert a disk which has been formatted by the MDF3 (or MDF2). 63  Other errors: !~Unformat~disk The disk in the disk drive has not been formatted, or has been formatted for a device other than the MDF3. Check the disk, and format it if necessary. !~~Bad~disk The MDF3 is unable to read or write data using the disk in the disk drive. The disk is either unformatted, or has been formatted by a device other than the MDF3 (or MDF2). If this message appears after you have formatted a disk, the disk is probably bad. Replace it with a new one. !~~No~file A function cannot be executed because the displayed file cannot be found on the current disk. You have probably changed the disk after selecting a file but before executing the function. Insert the disk containing the displayed file and execute the function again. !~~Battery~Low The batteries are running low. The MDF3 is not capable of functioning any longer. If you attempt to use the MDF3 after this message appears, the unit will not operate, or the message will appear again after a few seconds. Connect the AC adapter or replace the batteries with a new set. MIDI-related errors: Note: If the “YAMAHA MDF3” initial display !~MIDI~data~err There is something wrong with the MIDI data being received. Check the transmitting MIDI device and the MIDI cable. appears when you start a playback or recording operation, it means the battery power is so low that the MDF3 cannot display the “Battery Low” error message. Connect the AC adapter or replace the batteries quickly. !~~Illegal~file You have selected a file written using a data format other than those which the MDF3 is capable of reading. Select another file. The MDF3 can only read standard MIDI files (format 0/1), ESEQ format sequence data files, and MDR data files created by the QX3 in MDR mode. 64 !~~Disk~eject !~MIDI~data~full The amount of MIDI data received at one time has exceeded the MDF3’s processing capacity. Decrease the amount of data being transmitted to the MDF3. A disk has been removed from the disk drive during playback or recording. Never eject a disk during playback or recording, as doing so can damage the disk or the disk drive.  ABOUT THE MIDI IMPLEMENTATION CHART The MIDI implementation chart is useful for determining the function compatibility of different MIDI devices. The chart is essentially a list of the MIDI functions supported by a MIDI device. The various possible MIDI functions are listed in the far left column of the chart. The two columns to the right of this list tell you whether the device in question supports the transmission and reception, respectively, of MIDI data related to the function. Supported functions are indicated by an “O”, whereas unsupported functions are marked by the letter “X”. To determine whether two devices are compatible with regard to a specific function, compare their implementation charts. If one device supports transmission of a function and the other supports reception, the two devices can use the operation. Note: The MDF3’s MIDI implementation chart is enclosed with this manual as a separate sheet. This sheet also gives a detailed description of the MDF3’s MIDI functions. By inspecting a device’s implementation chart, you will get a good idea whether the device is more suitable for use as a master or a slave in your MIDI system. Generally speaking, the more O’s a device has in the transmission column, the better it will perform as a master device; the more O’s it has in the reception column, the better it will serve as a slave. 65  SPECIFICATIONS MDR Section: File Capacity: Recording Capacity: Time Resolution: Record File Format: Play File Format: Displays: 99 max. approx. 1,200 KB per 1 file (when using MF2HD) 10 msec./tempo q = 60 (fixed) Standard MIDI File format 0 Standard MIDI File format 0 or Yamaha QX3 MDR Sequencer Section: File Capacity: Number of Tracks: Number of Notes: 99 max. 1 (16 MIDI Channels) approx. 150,000 notes (when using MF2HD) Note Resolution (internal): 1/96 of quarter note Note Resolution (MIDI sync): 1/24 of quarter note Tempo (play): q = 30 to 250 Tempo (record): q = 120 (fixed) Simultaneous Record Notes: 64 max.
