Music Disk Recorder
The Music Disk Recorder (M.D.R.) is a sophisticated recording device built into the Electone 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, the M.D.R. lets you play back commercially available XG song data, and allows you to execute song
copy operation even between different disks and disk copy operation which makes it possible to create a
backup disk.

1 Precautions

Be sure to handle floppy disks and treat the disk drive with care. Follow the important precautions below.
Compatible Disk Type
3.5ﾓ 2DD and 2HD type floppy disks can be used.
A blank 2HD floppy disk has been included with
your Electone 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.
LED (Lamp in-use)
NOTE:
When the EL-900 is turned on, the LED below the floppy
disk slot will be lit indicating that the M.D.R. is ready to
use.

Eject button
To eject a floppy disk:
Before ejecting the disk, be sure to confirm that
the M.D.R. is stopped (check if the LED above
the STOP button in the M.D.R. section 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. 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.
