Clock Multiplier

Takes an incoming clock and emits a faster one, firing a whole number of evenly-spaced triggers for every pulse it receives. Use it to drive hi-hats off a kick clock, generate ratcheting subdivisions, or run a sequencer at a tighter grid than your master clock.

How it works

The module times the gap between two clock pulses, then divides that period into Ratio equal slices. It fires one trigger on the downbeat and schedules the rest evenly across the period, so the multiplied pulses stay locked to the source. Because it has to measure a full period first, the new rate settles one clock after you patch in or change tempo. A gap longer than four seconds is read as the clock stopping rather than a slow tempo, so that period is ignored and the previous rate is kept until a fresh pulse re-measures.

Controls

  • Ratio — how many output triggers per input pulse, from 1 (pass-through) to 16. At 2 you get eighth-notes from a quarter-note clock, 4 gives sixteenths, and so on.
  • CV — attenuverter for the Mult CV input: how much (and which polarity) a patched CV shifts the Ratio. At 0 the CV input does nothing; dial it up for CV-swept multiplications (great for ratchets), or negative to invert.

Inputs & outputs

  • CLK — the clock to multiply; patch any steady trigger or gate source.
  • RST — a rising edge clears the pending schedule and resyncs to the next clock, keeping you phase-aligned with the rest of the patch.
  • Mult CV — modulates the ratio, added to the Ratio knob through the CV attenuverter (±10 V spans the full 1–16 range at attenuverter 1). Sampled on each clock edge — so a step in CV takes effect on the next downbeat.
  • OUT — the multiplied clock, as 1ms triggers.

Tips

  • Send the same master clock to CLK here and to your sequencer's RST, so the multiplied grid and the pattern always line up.
  • Turning Ratio up while running gives sudden ratchets and rolls — great for fills, nudged from 2 to 8 or 16.
