Master Clocker

The QCD is perfect for syncopated and rhythmic triggering. For example, you can clock a bass drum out from channel one, a snare out from channel and divide by 2 (/2) and then send channel 4's trigger out to a high hat module and multiply by anything. Tap in a new tempo with your finger and everything stays in sync. This module is instantly awesome!

• Four CV-controlled Clock Divider/Multipliers
• Tap tempo button and five sync'ed clock outputs make the QCD perfect for head-of-the-chain "Master" clock module
• Tap clock output runs at the tapped tempo (even if other channels are being clocked externally)
• Create complex rhythmic patterns by patching multiple channels into each other's Div/Mult CV and Reset
• Each of the four channels has an independent clock IN, OUT, Reset and Div/Mult CV
• Divide or Multiply incoming clock from /32 to x16 on each channel: Detented knob to snap to integer division/multiples, CV jack to modulate Div/Mult amount
• Reset jack (per channel) restarts the clock when a trigger is received (alters phase of clock)
• Clock input jacks are normalized downwards: Tap->Red->Black->Blue->Green
• Clock outputs stop automatically when incoming clock stops
• LEDs blink to output clocks' tempos
• 5V clock output pulses, fully buffered. Default is square-wave, and PW is controllable with expander
• Daisy chain multiple QCDs or other clock modules using Tap Out jack
• Header on the PCB to connect to Quad Pingable LFO (QPLFO) to provide four CV Skew-able, CV Div/Mult-able envelopes
• Interfaces with QCD Expander for more features (Pulse Width, Inverted Gate, attenuverters for CV inputs)
