SignalFunctionSet Gravity

SignalFunctionSet Gravity

Gravity-driven chaos engine with six modes — double pendulum, orbiting gravity well (a spring-bound rocket perturbed by planets), elastic billiards, a Pac-Man-style maze (Hungry Man), a LOGO Turtle that draws random generative artwork, and a Pattern generator that traces spirograph/Maurer-rose figures — all sharing bipolar X/Y position, radius and angle CVs, six morph-crossfaded sector distance CVs, and six boundary-ray gates. Speed, chaos, and a mode-dependent gravity control; drag on the display to throw/aim.

SignalFunctionSet Muse

SignalFunctionSet Muse

Faithful Triadex Muse sequencer port. 4 Theme + 4 Interval sliders each select one of 40 taps (counters + 31-bit XNOR-feedback shift register); Theme bits drive the SR feedback, Interval bits address a diatonic scale. External clock, V/oct + gate out, randomize button/CV, selectable scale.

SignalFunctionSet Vac

SignalFunctionSet Vac

Semi-stable A/R envelope with vactrol-like drift. Rise and fall each have a bipolar STAB control: each trigger samples a fresh random factor scaled exponentially by STAB, so cycle-to-cycle timing wanders without ever collapsing. Linear↔exponential CURVE (with CV), latching LOOP, END trigger out.

Animatek UNIT-D

Animatek UNIT-D

Compact deterministic polyphonic generative sequencer based on unit-distance graph walks. Seeded 2D nodes create graph transitions, with musical density, gate-density and bipolar 16/32-step gradual lock controls, quantized minor-scale pitch, gate, accent, X CV and Y CV outputs.

SequencerRandomPolyphonic

SignalFunctionSet Shift

SignalFunctionSet Shift

4-output CV shift register. Per-lane step count, clock divider, step CV, and parallel/cascade mode (parallel = N-step delay line; cascade = tape-loop FIFO fed by the previous lane). Per-lane CV + gate outs, plus a jumble pair (random pick across lanes + accompanying clock).
