■"Rackmount Midi module, a slimmed-down Korg M1 / M1r workstation version featuring less waveforms and a simpler voice architecture." rackmount unit, main panel features a 16 X 2 lines display, a knob for volume and 8 buttons, no really easy to program.
- M3R OS check :Turn on the MR3 and keep hold EDIT + GLOBAL
- M3r FACTORY RESET: EDIT, GLOBAL, go to page 5, RELOAD PRESET, OK
■Terminal connectors:
1- Midi interface
2- main analog signal out
3- AUX analog out assignable
4- a 8 DIN pins connector called "REMOTE" for external programmer model Korg RE-1
- headphones out (front)
- 2 card slots for PCM and data cards (front)
■SOUND the rack main core is a single 8 bits NEC model D70320 which manages up to 16 voices polyphony; DAC is a Burr Brown PCM54HP.
A patch is composed by 1 sample PCM at 16 bits resolution based on "AI SYNTHESIS" with some edit parameters: octave range: 4' / '8' / 16', volume gain setting, stereo panning , delay start and monophonic mode.
Internal 3 MB ROM is organized in 3 wave categories: 45 PCM: percussives + 80 PCM acoustic instruments + 9 DWGS mathematically pre-calculated PCM derived from classic hybrid analog-digital Korg DW-8000. Rom can be expanded with several cards (list on new chapter), M3R wavetable can be expanded using some cards usually set of PCM+DATA: HINT: M3R and M1/m1r PCM cards are compatible, but not the DATA ones.
■FILTER VDF is digital, a simple non-resonant low-pass model.
■LFO Up to 2 delayed modulators MG (4 shapes: triangle, saw-up, saw-down and square) with variable depth and retrigger option mode: LFO 1 to pitch / LFO 2 to filter.
■ENVELOPE 3 digital EGs:
- EG OSC VDA: 4 segments + 3 times
- EG OSC VDF: 4 segments + 4 times
- EG OSC pitch EG: 3 segments + 3 times
■EFFECTS double digital engines that can be chained in either serial or parallel mode : equalizer, reverb (x9) delay (x2), chorus (x2), flanger (x2), tremolo (x2), phaser (x2), frequency exciter and ovedrive.
■MEMORY: 100 programs + 100 combinations, RAM doubled when using custom MCR-03 memory ards.
Battery Replacement : a simple CR2032 in a simple holder: just open the rack, locate the holder then replace it with a fresh one. Then you have to reload your sounds: the factory patch set can be recalled anytime just follow this simple keystroke procedure: EDIT, GLOBAL, go to page 5, RELOAD PRESET, OK
