Compliance with these requirements provides a reasonable level of assurance that your use of this product in a residential environment will not result in harmful interference with other electronic devices. [. . . ] Once the block has been transmitted, the PAUSE key LED will light steadily to indicate that the MDF1E has paused. The MDF1E will resume transmission when you press the PAUSE key again or press the foot switch if it is connected. You can cancel transmission by pressing the START/STOP key. The MDF1E will end transmission after it has sent the current data block. The file selection display will reappear when the transmission of MDR data is complete. 28 Notes on MDR Data Reception and Transmission Reception MDR file size: On a newly formatted 2HD disk, a single 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. MDR Transmission MDR file formats: In addition to its own files, the MDF1E 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. Bulk data blocks: The MDF1E recognizes bulk data blocks by their header (System Exclusive status: F0H) and footer (End of Exclusive: F7H) values. Block intervals: When the MDF1E creates MDR files, it also records timing data at 10 millisecond intervals. If the interval between any two data blocks exceeds one second, the MDF1E 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) Transmitting QX3 data: When the MDF1E 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 When you record data in SEQ mode, the MDF1E automatically writes this data to disk as a SEQ data file using Standard MIDI File format 0. Select a file to transmit. Using the FILE DATA keys, select the file to be played back.

Prepare the receiving device. 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. 5. Start the playback. Press the START/STOP key. The MDF1E 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. 6. Change the tempo. 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 file name performance time SONGå01~~~~oe=120 file name tempo Note: When you press the START/STOP key, the MDF1E 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 MDF1E 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 Note: Sequence data files created by devices other than the MDF1E may include tempo change data that will alter the tempo regardless of the changes you make using the FILE DATA keys. [. . . ] This product, either alone or in combination with an amplifier and headphones or speaker/s, may be capable of producing sound levels that could cause permanent hearing loss. DO NOT operate for long periods of time at a high volume level or at a level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should consult an audiologist. IMPORTANT: The louder the sound, the shorter the time period before damage occurs. [. . . ]
