The QCD Expander from 4ms Company is an expansion module for the Quad Clock Distributor (QCD). The QCD Expander requires the QCD to function, and adds a host of features. The Expander turns the QCD into a programmatic non-linear sequencer, easily obtaining self-patched evolving rhythms, and swing/shuffle patterns.

Each of the four channels has:

  • Multi-mode output jack INV OUT mirrors the tempo of main QCD output
  • Mode Switch for each INV OUT jack:
  • Delayed Trigger Mode
  • Inverted Gate Mode
  • Shuffle Mode (delayed + original trigger)
  • PW/Delay knob controls trigger delay time on INV OUT jack (or pulse width in Inverted Gate Mode)
  • Also controls Pulse Width of main QCD OUT jack
  • CV input jack for external control
  • Attenuverter allows for one channel to precisely modulate another channel’s delay or pulse width
  • Div/Mult CV attenuator knob
  • Controls how much the signal on the main QCD’s Div/Mult CV jack will modulate the tempo
  • Useful for precisely modulating the speed of one channel with another
