KORG M1R Synthesizer music workstation VOICES INFORMATION NEC-V50 CPU manages 16 digital oscillators based on 16 bit AI System subtractive synthesis. A basic patch is composed by 1 (Single mode) or 2 (Double Mode) detunable digital oscillators OSC1+ OSC2 with variable Octave range and Coarse. An oscillator has a PCM waveform assigned from the wavetable and this waveform can be read at variable memory offset and start-delayed. WAVETABLE 4Mb ROM for 149 different waveforms split in 2 main sounds groups: PERFORMANCE COMBI mode manages up to 8 patches in the same time with individual Midi channels, Volume mix, Transpose, Detune, Zone Split, Velocity Split and Damper on filter. MEMORY 100 patches + 100 Combi in RAM, NO ROM recall. Internal voice backup on lithium Cr-2032 or backup to a RAM card mode MCR-03 must be a 256 Kb memory as it is not compatible with 128 Kb MCR-02. MIDI limited Midi Control changes implementation, but the exclusive systems are complete.
