Product Description
Additional Information
  • Product Description

    The 4MS 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.


    • 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.

    • Power consumption:

    • +12V rail: 44mA max
    • +5V rail: not used
    • -12V rail: 30mA max
