The MR-Rack is the rackmount version of the Ensoniq MR-61 synthesizer. It can be expanded with up to 3 of the EXP series expansion boards.
It has a BR2330 3-volt lithium memory backup battery soldered to the motherboard. When it dies and needs to be replaced, a battery holder should be installed in its place in order to avoid the need to solder future replacements. A CR2032 battery is a good substitute that is more commonly available.
One of the more memorable patches is a string patch called "warm bath".
The MR series contains 36 transwaves that can be used to generate wave sequences.
Transwave list:
Year Released: 1996
MSRP: 1695.00 USD
Polyphony: 64 notes
Multitimbral: 16 parts
ROM: 12MB
Effects: 40
