4ms Quad Clock Distributor
Four-channel CV clock divider multiplier with tap tempo
10 HP Eurorack module
The Quad Clock Distributor is a four-channel voltage-controlled clock divider and multiplier with master tap tempo, capable of dividing or multiplying clocks from /32 to x16 per channel. Each channel can sync to the tap tempo, to the channel above, or to an external clock, making it a versatile rhythmic hub for complex, evolving trigger patterns. Its normalization scheme, reset jacks, and CV inputs allow for sophisticated polyrhythmic and shuffle-based beat generation.
Features
- Four independent CV-controlled clock divider/multipliers covering /32 to x16 per channel
- Detented Div/Mult knobs that click at integer division and multiplication values
- Tap Tempo button with dedicated TAP OUT jack running at tapped tempo regardless of channel clock sources
- CLK IN jacks normalized downward: Tap->Red->Black->Blue->Green
- Plugging into a CLK IN jack clocks that channel and all channels below with the same clock
- Reset jack on each channel restarts the clock phase when a trigger is received
- Auto-stop: each channel stops automatically when the incoming clock stops
- Div/Mult CV jack per channel: 0V to 10V sweeps full range, knob provides offset
- Channels can be stacked for extended range of /1048576 to x65536
- Gate Mode (50% duty cycle) or Trigger Mode (12ms pulses) selectable via PCB jumpers
- LED brightness adjustable via trimpot accessible through front panel hole
- Threshold trimpot on back adjusts triggering voltage for CLK IN and Reset jacks (default 2.5V, range 0V-5V)
Controls & Jacks (26)
