Music Disk Recorder The Music Disk Recorder (M.D.R.) is a sophisticated recording device built into the AR-80 that lets you record your performances and Registration settings. The Music Disk Recorder not only records the notes you play; it also remembers the voices and rhythms you select, the front panel controls you change, as well as all expression pedal, footswitch and knee lever positions, to reproduce your performance exactly as you play it. Moreover, you can separately record different parts of your performance, building up a song part by part. M.D.R. Precautions Be sure to handle floppy disks and treat the disk drive with care. Follow the important precautions below. Disk Types The M.D.R. uses 3.5" 2DD and 2HD type floppy disks. A blank 2DD floppy disk has been included with your AR-80 for you to record your performances. DISK IN USE Lamp This red lamp lights during disk read/write operations,such as when a disk has been inserted,during recording, playback, formatting, etc. 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. Drive Lamp This green lamp is always on when the power to the AR-80 is on, regardless of M.D.R. operation. When the AR-80 is turned on, the lamp below the floppy disk slot lights, indicating that the M.D.R. is ready to use. To eject a floppy disk: • Before ejecting the disk, be sure to confirm that the M.D.R. is stopped (check that the STOP button's lamp is lit). 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. • Never attempt to remove the disk or turn the power off during recording, reading and playing back (when the DISK IN USE lamp is lit). 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. 83
