The Clock sets the tempo for the whole patch. It makes no sound: it sends gates, 10 V pulses, at a steady pace. A sequencer moves one step forward on each rising edge it receives. Everything runs inside the audio engine, sample-accurate: the rhythm never drifts.

Controls

  • BPM: tempo in beats per minute (20 to 300), shown in red above the knob.
  • Run: on or off. When it starts, the clock begins again from the first beat. The ▶/■ button in the top bar switches every Clock in the patch at once.
  • Reset (button): sends the clock back to the first beat and fires a pulse on Rst.
  • MIDI: follows the MIDI clock of an app (Ableton…) or a device. The host's tempo replaces the BPM on the display; Start begins again from the first beat (pulse on Rst), Stop stops, Continue resumes.

Inputs

  • Run: each rising edge toggles on/off; the LED shows the real state.
  • Reset: a rising edge does the same as the button.

Outputs

All outputs are in phase, with 50% duty-cycle gates (high half the time).

  • ×1: one gate per beat (a quarter note at the shown tempo).
  • ×2: two per beat (eighth notes).
  • ×4: four per beat (sixteenth notes): sixteen steps per bar, the usual speed for a sequencer.
  • /2: one gate every two beats (half notes).
  • /4: one gate per bar (whole notes).
  • Rst: a 1 ms pulse on reset and on start. Patch it into the RESET input of your sequencers and it brings them all back to step 1 together.
