The MM-981 is a cool Oscillator Module reminiscent of the PPG 301 VCO module. Multiple waveforms, PWM and Sync Inputs/Outputs make this quite a versatile module.

Controls

Octave - 11-way control switch to determine the Octave

Semitones - Fine tune the pitch in semitones (or smaller)

CV 1 - Attenuation of the CV1 Input signal to control pitch.

CV 2 - Attenuation of the CV2 Input signal control pitch.

Pulsewidth - Determines the duty cycle of the Square Wave Output.

PWM1 Atten - Attenuation of the PWM1 Input signal to control the Pulsewidth

Inputs

CV 1 / 2 - Controls the Pitch of the oscillator, and can be attenuated by the CV1/2 Control knobs.

2x 1v/Oct - Standard Pitch Inputs from keyboards/sequencer outputs.

PWM1 - Controls the Pulsewidth - this signal is attenuated by the PWM1 Atten control.

PWM2 - Controls the Pulsewidth.

Sync In - Sending a HIGH trigger signal in here will reset the cycle of the oscillator. Send in an output from another oscillator to geet those cool sync-lead sounds!

Outputs

4x Wave Outs - Seperate outputs for Saw, Square, Triangle and Sine Waves.

Sync Out - Sends out a short HIGH signal at the start of every cycle.
