Algo-rhythmic dual trigger generator. Five rhythmic tables (Euclidean, Divider, Anti-Euclidean, Split) multiplied by five Out 2 modes build practically infinite polyrhythms from a single clock.

Behaviors

Main Mode (MN) Mode LED = MN

Utility sub-modes on Out 2: Reset (pulse every first step), No Shift (same as Out 1 but immune to Shift), Invert (inverse of Out 1), Backward (Out 1 pattern reversed).

Compute Mode (CP) Mode LED = CP

Out 2 plays a related sequence derived mathematically from Out 1: L & P/2, L/2 & P/2, 2L/3 & 2P/3, L-P & P/2. Final sub-mode auto-resets Out 2 from Out 1.

Random Mode (RD) Mode LED = RD

Adds randomness to Out 2. Sub-modes: No Random, Soft Fill (low-probability read of L/2+P/2 pattern), Hard Fill (higher probability), Full Random (per-step probability scaled by Pulses).

Dual Mode (DL) Mode LED = DL

Out 1 and Out 2 carry independent settings. Pots must cross their stored value before taking effect (Length+ LED flashes). CV inputs disabled in this mode.

Record Mode (RC) Mode LED = RC

Record sequences via +/- buttons (- to Out 1, + to Out 2), quantized to incoming clock. Sub-modes: Record and Play. Pulses CW causes outputs to roll (trigger every step).

Extended Length Range Mode + Table held

Toggles Length range between 1-8 (default) and 9-16 steps. Length+ LED lit confirms 9-16 range.

Controls

Global Length Potentiometer Sets sequence length from 1 to 8 steps. Mode+Table together extend range to 9-16 steps.
1-8 default · 9-16 via Mode+Table · Length+ LED shows extended range · CV input additive
Global Pulses Potentiometer Number of hits in the sequence. Full CCW mutes outputs. Full CW distributes maximum hits. CV-addressable.
0 hits = mute · max CW = all steps active · Record mode: CW rolls triggers every step
Out 2 Mode Button Cycles through five modes controlling how Out 2 derives from Out 1: Main, Compute, Random, Dual, Record.
MN · CP · RD · DL · RC · sub-modes via Mode+/- buttons
Out 1 / Out 2 source table Table Button Selects one of five rhythmic tables: Divider, Classic Euclidean, Revised Euclidean, Anti-Euclidean, Split Sequences.
Boots on Revised Euclidean · Mode+Table combo toggles 9-16 step range
Global +/- Shift Buttons Rotates the sequence one step forward or backward. Holds function as sub-mode navigation while Mode is held.
+ = forward 1 step · - = backward 1 step · also edit sub-modes · records patterns in RC mode

IN · 4

  • Clock 0-5V CLK
    External clock advancing the sequence.
  • Length CV 0-5V CV
    CV offset added to the Length pot value.
  • Pulses CV 0-5V CV
    CV offset added to the Pulses pot value. In Record mode, controls roll density.
  • Reset 0-5V
    Restarts both outputs to step 1.

OUT · 2

  • Out 1 0-5V GATE
    Primary trigger output of the selected table/length/pulses/shift combination.
  • Out 2 0-5V GATE
    Secondary trigger output algorithmically derived from Out 1 per the selected mode and sub-mode.
