QCD Expander:

Connects to QCD main module with a 16-pin cable
Pulse Width control for each channel, expressed as a percentage (duty-cycle) of total time (e.g. 50%, or 10%)
PW jack and attenuverter to modulate Pulse Width
Attenuverter for Div/Mult jack from the main module allows for fine tuning the tempo shift
Second set of output jacks provide a duplicate of the clock outputs. Very useful for using channels to modulate other channels
