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.
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 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.
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.
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.
