Seq8 - 8-Step CV/Gate Sequencer

Simple 8-step sequencer with internal clock and external sync support.

Overview

Seq8 cycles through 8 steps, outputting a CV voltage and gate pulse for each step. It can run from its internal tempo (40–200 BPM) or lock to an external clock with a selectable multiplier. A reset input returns the sequence to step 1, and RESET takes priority when RESET and clock arrive on the same sample.

Parameters

STEP 1–8 (0.0–1.0, default 0.0)

  • CV value for each step (output range: 0–10V)
  • Examples:
  • Value = 0.0: 0V output
  • Value = 0.5: 5V output
  • Value = 1.0: 10V output

TEMPO (default 0.5)

  • Without external clock: sets internal tempo from 40–200 BPM
  • With external clock: selects sync multiplier
  • 0.25x / 0.5x / 1x / 2x / 4x
  • LED: Tempo LED pulses at the active rate; brightness increases with tempo
  • Examples:
  • No clock, Tempo = 0.0: 40 BPM
  • No clock, Tempo = 0.5: 120 BPM
  • No clock, Tempo = 1.0: 200 BPM
  • Clock connected, Tempo = 0.0: 0.25x (one step every 4 clocks)
  • Clock connected, Tempo = 0.5: 1x (one step per clock)
  • Clock connected, Tempo = 1.0: 4x (four steps per clock)

I/O / CV

  • Audio In: None
  • Audio Out: None
  • Clock In: External clock input (triggers step advance)
  • Reset In: Reset trigger (returns to step 1)
  • CV Out: Step CV (0–10V, mono), available at the left output jack
  • Gate Out: Gate pulse per step (10V, mono), available at the right output jack

Behavior Notes

  • When an external clock is connected, the Tempo knob switches to sync multiplier mode: 0.25x / 0.5x / 1x / 2x / 4x
  • RESET takes priority: if RESET and Clock triggers arrive on the same sample, the clock event is ignored and the sequence resets to step 1
  • Changing the sync multiplier resets the internal phase counter to prevent drift
  • Gate pulse duration is 1ms
