The MM-981 is a bank of 5 Voltage-Controlled Oscillators with a dedicated driver section with master control of frequency and Pulsewidth. Make massive chords or huge unison leads and basses!

Driver Controls

The base frequency and pulsewidth for all the oscillators is set by the Driver section, although each oscillator can then be adjusted independently.

1v/Oct - Input to control pitch, usually from a keyboard or Sequencer Pitch Output. These can be transposed with the OCTAVE and SEMITONE controls.

CV1 - Secondary pitch input for modulation.

PWM1 - Input for Pulsewidth Modulation.

Individual Controls

Octave / Semitones - Adjust each oscillator independently from the base frequency set in the Driver section.

Sync In - Each oscillator can be synchronised to an external signal, resetting the cycle on a HIGH trigger signal.
