Under construction

The voltage controlled oscillator is one of the essential core modules in your modular analogue synth. The M²Synth has a few options for VCOs:

  • VCO 101 with sync inputs and sub octave pulse outputs
  • VCO 102 is a quad VCO with preset chord intervals between the VCOs
  • VCO 103 is a mini version of the 101 without the sync and sub octave features
  • Voice 108 has in addition to a VCO, other core functions including a filter, VCA, noise, ADSR etc.

Overview 

This module, the Voice 108 contains all of the essential elements of an analogue synth in a single 'voice' module. It uses toggle switches for patching with additional jack sockets for integrating into your modular synth.

Voice 108 Functions: VCO, LP VCF, VCA, ADSR, LFO, Noise generator, Mixer & Gate Pulse Generator

Voice 108 Patching:

  • ADSR gate - internal from repeat gate generator or external source
  • VCO frequency modulation from LFO or ADSR
  • VCO PWM modulation from LFO or ADSR
  • VCF cut-off modulation from LFO or ADSR
  • VCF cross modulation from LFO or ADSR
  • VCA level from LFO or ADSR
