26 modules in plugin
SignalFunctionSet GSX
Granular synthesis module based on Barry Truax's GSX system (1985-86), with real-time control over temporal, spectral, and spatial parameters
SignalFunctionSet Phase
Dual sample looper with phase drift via sleep and rotate modes, transient detection, and waveform display
SignalFunctionSet Overtone
Additive synthesis VCO with 8 individually-toggled harmonics, even/odd filter, binary mask CV, and waveform display
SignalFunctionSet Intone
CHANT/FOF formant synthesis voice with vowel morphing, 5 formant cells, and dual excitation modes
SignalFunctionSet Tine
Tunable 3rd-order pingable resonator based on the Gamelan Resonator circuit, with variable damping and VCA anti-click mode
SignalFunctionSet Fugue X
Expander for Fugue — per-voice steps, range, sleep, probability, S&H mode, sorted CV outputs, and per-step trigger outputs
SignalFunctionSet MetaFugue
Single-module merge of Fugue and Fugue X on one wider panel. Adds the per-voice steps/range/sleep/probability, S&H mode, sorted min/mid/max CV outputs, and per-step triggers. Ideal for hosts without expander support, such as MetaModule.
SignalFunctionSet Meter
Time-signature-aware musical clock with bar/quarter/eighth/sixteenth/triplet outputs, CV-controllable time signature, and external clock sync
SignalFunctionSet Meter X
Expander for Meter. Adds a 24 PPQN clock, a Run gate, and Bar / 2 / 4 / 8 / 16 / 32 / 64 / 128-bar trigger outputs, each with an activity LED. Place directly to the right of a Meter.
SignalFunctionSet Beat
Single-voice pattern sequencer with 8 patterns x 16 steps, on-screen step/velocity/accent editing, per-pattern length, and active-pattern progression
SignalFunctionSet Note
Monophonic CV/gate pattern sequencer with 12-note pitch matrix, scale and root selection (incl. just-intonation harmonic series), 8 patterns x 8 steps with velocity/accent/probability editing
SignalFunctionSet Swell
Ping-driven additive A/D envelope generator. Each ping adds voltage with its own rise, and pings stack additively over a continuous linear or exponential decay. Soft-saturated 0-10V output.
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).
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.
SignalFunctionSet Muse
Faithful Triadex Muse port. Four Theme and four Interval sliders each tap one of 40 sources (counters plus a 31-bit XNOR shift register) — Theme bits feed the register, Interval bits address a diatonic scale. External clock, V/oct + gate out, randomize, and selectable scale.
SignalFunctionSet Gravity
Gravity-driven chaos engine with six visual modes: double pendulum, orbiting gravity well, elastic billiards, a Pac-Man-style maze, a LOGO turtle, and a spirograph/rose pattern generator. All modes share bipolar X/Y, radius and angle CVs, six sector-distance CVs, and six boundary-ray gates. Speed, chaos, and a mode-dependent gravity control; drag the display to throw or aim.
SignalFunctionSet Band
Harmonic bandpass bank. Four narrow bands each lock to an integer harmonic of a shared 1V/oct fundamental, isolating individual harmonics of a rich low wave. Per-band level and enable with a global harmonic-shift CV, plus mix and polyphonic per-band outputs.
SignalFunctionSet Cycle
Bar-synced quad LFO. Four channels (A-D), each with its own morphable shape and depth, lock to a musical bar via clock + bar inputs (free-running in Hz when unpatched). Global phase spread and stability, per-channel unipolar and bipolar outputs, and full CV.
SignalFunctionSet Operator
DX7-style 6-operator FM voice. Loads Yamaha DX7 .syx cartridges (or your own banks exported from Dexed), selects a voice, and plays it polyphonically. Built on the msfa FM engine.
SignalFunctionSet OP ENV
Standalone DX7 operator envelope. Pick a voice from a DX7 .syx bank to load its carrier envelope, offset each of the eight EG attributes (rates and levels) via trimpot or CV, fire it with a gate, and get a 0-10V envelope.
SignalFunctionSet Chance
5-stage probabilistic step sequencer. Per-stage voltage slider plus repeat, probability, and harmonic-drift amounts; selectable direction, active length, and gate length; internal or external clock; CV/Gate/EOC outs and a randomize trigger.
SignalFunctionSet Record
Multisample auto-sampler. Drives an external voice with V/oct, gate, and velocity and captures its stereo output across a chosen note range and velocity layers, then writes a folder of WAVs plus an .sfz manifest.
SignalFunctionSet Play
Polyphonic multisample player. Loads SFZ instruments (including those written by Record) and plays them polyphonically via V/oct, gate, and velocity, with CV instrument selection and stereo output.
SignalFunctionSet Arrange
Song-form / arrangement sequencer. A linear chain of 8 phrases (bar-length sections); each phrase has a bar length, root + scale, BPM (linkable — a linked phrase inherits BPM/root/scale from the previous one), a gate out that stays high while it plays, and 4 channel enables. The 4 channels are per-instrument clock buses with clock division and CLOCK / BAR / RESET / EOC outputs each, muted on phrases where the channel is off — instruments drop in and out per phrase. Driven by a bar-rate clock. Master outs: phrase index (1V/phrase), BPM CV (for Meter), root + scale CV. The arrangement brain above Beat / Note / Chance.

VCV Library Instructions
- Download and install VCV Rack.
- Register for a VCV account and log in using Rack’s “Library” menu.
- Add or purchase a module on the VCV Library.
- Open the “Library” menu in Rack, click “Update all” (if updates are needed), and restart Rack once downloaded.
- Right-click an empty rack space to launch Rack’s module browser to add a module to your patch.
All plugins on the VCV Library are available for Windows, Mac, and Linux.
The “major” version (i.e. MAJOR.MINOR.REVISION) must match between Rack and its plugins.
For example, Rack 2.* can only load 2.* plugins.
