4MS QCD Expander

QCD Expander (QCD Exp.)
The QCD Expander is an expansion module for the Quad Clock Distributor (QCD). The QCD Expander adds a host of features, turning the QCD into a programmatic non-linear sequencer. Each channel gets a CV Trigger Delay (Pulse Width) jack and knob, an additional output jack with three selectable modes, and attenuverters for all CV input jacks. Self-patched evolving rhythms and swing/shuffle patterns are easily obtained, as well as complete control over standard rhythmic patterns.
Basic features
Connects to QCD module with a 16-conductor ribbon cable (included)
More features are added to each QCD channel:
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

Global LED brightness can be adjusted from the front panel

Module size: The QCD Expander is 12HP and 0.98″ (25mm) deep. Four knobbed pots have a metal shaft and nut. Eight knobless pots are center-detent with white indicator line.
