MDR (Music Disk Recorder) Electone disk drive

The MDR was produced to solve the problem of not being able to record a performance on a RAM Pack,
and because of the high price of the RAM Packs. It is able to store 16-40 files (depend on model).
Each file can contain Registrations, user voice data, panel settings, current registration (which may not
be saved in the Reg. Mem) global settings, and a performance (even in parts - upper/lower/pedal/etc.).
This device is a "must have" for any Electone owner who wants to save his registrations and
performances shortly - all of us. The MDR needs to be connected via both MIDI ports (it has
MIDI through for connection of other modules) and no line connection. All data transmission
with the MDR is done via MIDI.
