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

- 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)

 

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).

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

 

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.
