4ms Company QCD Expander

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.

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
