OP ENV
A standalone DX7 operator envelope generator for VCV Rack. Loads a voice from a .syx bank and turns its carrier envelope into a gate-driven CV, with per-stage offsets.
VCV Rack
Free, open-source modules for VCV Rack. Most also run on the 4ms MetaModule.

Operator
A 6-operator FM synth voice for VCV Rack in the Yamaha DX7 lineage. Loads DX7 .syx cartridges, plays them polyphonically, and ships with classic Brian Eno patches.
Cycle
A bar-synced quad LFO for VCV Rack. Four channels lock to your song's bar grid with morphing shapes, per-channel depth, and clock-quantized staircases: built to pair with Meter.
Band
A harmonic bandpass bank for VCV Rack inspired by Suzanne Ciani. Four narrow filters lock to integer harmonics of a shared fundamental that auto-tracks the input.
Gravity
A 30HP multi-mode chaos and motion engine for VCV Rack. Six engines drive a moving point read out as bipolar X/Y CVs, six sector CVs, and six boundary-ray gates.
Muse
A VCV Rack recreation of the 1972 Triadex Muse by Edward Fredkin and Marvin Minsky. Eight sliders tap a binary network to generate long, structured algorithmic melodies.
Shift
A 4-output CV shift register for VCV Rack. One signal in, four outputs each with its own delay, divider, and parallel-or-cascade mode, plus a jumbled bonus output.
Vac
A semi-stable attack/release envelope generator for VCV Rack. Per-stage stability controls introduce musical cycle-to-cycle variation, like a real vactrol drifting.
SignalFunctionSet Sequencer System
A modular rhythm and pitch sequencer system for VCV Rack. Meter is the time-signature-aware master clock; Beat sequences drums; Note sequences pitched voices.
Swell
A ping-driven envelope generator for VCV Rack. Each trigger adds a soft-saturating rise; the envelope decays back toward zero with linear-to-exponential curve shaping.
Intone
A formant synthesis voice for VCV Rack based on the IRCAM CHANT project. Five parallel FOF cells with vowel morphing, audio excitation, and trigger modes.
Tine
A tunable 3rd-order pingable resonator for VCV Rack based on the Gamelan Resonator circuit from Paul DeMarinis' Pygmy Gamelan (1973).
Phase
A dual sample looper for VCV Rack inspired by Steve Reich's tape phase compositions. Two loops drift against each other to generate evolving phase relationships.
Overtone
An additive synthesis VCO for VCV Rack that builds waveforms by toggling individual harmonics of the overtone series. CV-controllable mask and filter inputs.
Fugue
An 8-step harmonic deviation sequencer for VCV Rack. Generates three voices of evolving counterpoint from a single melodic sequence using interval offsets.
GSX
A real-time granular synthesis module for VCV Rack inspired by Barry Truax's pioneering GSX system. Grain density, duration, pitch, and spray under full CV control.
Drift
A 4-channel chaos LFO for VCV Rack with independent phase offset, per-channel scaling, and waveform morphing from sine through chaos. Built for generative patches.
