Description

Michigan Synth Works' 10 HP version of Mutable Instruments' open source Edges, a quad chiptune oscillator, with a MIDI input added. Three square-wave voices and a fourth playing a triangle, a sine or noise, each with its gate, V/oct and modulation inputs and its own output, mixed together at MIX OUT; cross-modulation between the voices; the four voices played from MIDI on four channels or polyphonically on one.

Key features

  • Four voices: three square waves (50 to 95 % pulse width, or PWM by CV) and a triangle, sine or noise voice
  • A gate per voice opening it, normalled from one voice to the next, as are the V/oct inputs
  • XMOD: hard sync of 1 to 2, ring modulation 1 x 2 and 1 x 3
  • A level per voice into the mix, an output per voice
  • A MIDI input (TRS), LEARN for the base channel and MODE for four channels or polyphony
  • An 8-step sequencer and a semitone quantizer per voice, in its settings
