4ms Company - Quad Clock Distributor [QCD]

Four channel voltage controlled Clock Divider/Multiplier with master Tap Tempo. Each channel can be synced to the tap tempo, to the channel above, or to an external clock. Each channel also has a reset jack.

With a Tap Tempo button and five sync'ed clock outputs, the QCD is a versatile head-of-the-chain "Master" clock module, and/or a complex rhythmic pattern generator.

Basic features:

• 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)
