PERFORMANCE basically the DRM-1 can be played in 3 ways:

trigger in - Midi interface with velocities (e.g keyboard, drum machines):

- Trigger interface (hook up to electronic drum pad ) up to 8 sound samples can be assigned to an invidual out and trigger input with adjustable pad sensibility. The incoming trigger signal are converted to Midi out data.

- Sequencer (described below)

 



edit
SEQUENCER patterns can be recorded in real-time mode with some features e.g : punch in/out options, overdub, loop mode, metronome, tempo change and quantisize (up to 1/48 resolution maximum).

sequencer editSYNC internal tempo (from 40 to 250 BPM) can be set by TAP tempo or synched to external Midi clock.


 

edit MEMORY:
- 16 settings
- 16 songs
- 4400 notes.
The Recorded sequences can be stored either to to magnetic tapes Midi exclusives or to a RAM card model MCR-02 (128kb) also compatible with MCR-03 (256kb) also used by workstation synthesizer Korg M1.

REVIEW "The DRM1 is a pain to use on this tiny panel, but once set it can be fun playing with triggers and old' 80 punchy sounds- still a good source for lo-fi percussion! Just be sure to get the remote controller or you will not be able to properely use/edit the unit."

"The DRM-1 digital rhythm module incorporated advanced sound generation capabilities in a compact body which fits a 1 unit rack. It comes with a wireless controller that allows the remote player to control most of the functions, a feature which is very handy for a drummer playing a series of digital drum pads." MANUAL
