QCD Expander


Out of stock

SKU: 4ms_QCD XPDR Maker: Type:


Expansion module for the Quad Clock Distributor (QCD).
The Expander turns the QCD into a programmatic non-linear sequencer, allowing you to easily create everything from self-patched evolving rhythms, to swing/shuffle patterns, to classic dance beats.

Each of the four channels has:

Multi-mode output jack INV OUT, which 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

A global LED brightness trimpot is accessible from the front panel.
