MADZINE MAD REPEATER
6HP single-stage envelope generator with clock sync, chainable to the right with F expanders for multi-stage envelopes
Coalescent Lineages
Generative ancestral-tree sequencer: sampled traits coalesce backward into a common ancestor or branch forward through neutral mutation.
Coalescent Archipelago
Eight-habitat local adaptation: selection follows a spatial environmental gradient while mutation, nearest-neighbor migration, climate, and a barrier shape clines and range shifts.
Coalescent Islands
Four-island Wright-Fisher drift: bounded stochastic allele-frequency CV with selection, mutation, migration, and founder bottlenecks.
Coalescent Finches
Trait-density ecology: mutation and frequency-dependent competition turn one phenotype into two persistent clusters.
Coalescent Foxes
Three-species food chain (Hastings-Powell): grass, bunnies, and foxes move from a regular chase through period doubling into deterministic chaos.
Roomi Fields OSC Controller
Remote-controls the whole Rack patch over OSC: set/get any parameter (by id or name), add/remove cables and modules, load/save presets, dump patch state, and serve an OSCQuery namespace for TouchOSC/Open Stage Control. Passthrough-compatible with osc-bridge.
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.
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 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 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.

forsitan modulare bulla
Rob Hordijk's Blippoo Box: two cross-modulating oscillators, two runglers and a twin-peak filter, between pattern and chaos.
forsitan modulare lustro
Scanned filter: scando's mass-spring string drives the band gains of a 16-band resonant filterbank.
forsitan modulare tabes
Disintegration looper: the tape loop degrades a little more on every pass (HF loss, saturation, hiss, dropouts, wow).
forsitan modulare ululo
Feedback guitar: six comb strings and a saturating amp in a howling loop, chord-tunable via poly V/oct.
forsitan modulare rete
Feedback integrator network: 8 nodes, random mixing matrix, self-oscillating chaos with per-node gain CVs.
forsitan modulare dræn
Drone synthesizer: two banks of 37 drone engines (dronecaster ports + hyf originals) played from fundamental (hz) and level (amp), with fading engine selection.
forsitan modulare pellicula
Exploded 8-voice drum sampler: per-voice sample/pitch/decay/level with knob + CV, poly-normalled matrix, per-voice/poly/mix outs.
forsitan modulare scando
Scanned-synthesis oscillator: a vibrating mass-spring string scanned into an evolving wavetable.
Eternal Eclipse Cosmic Clock
Astrological waveform engine — nine planetary LFO voices shaped by the zodiac signs they transit and mixed by live aspects, with a chart-of-the-moment wheel, end-of-cycle triggers, and time warp up to x100,000,000.
Eternal Eclipse Sephirothic Modulator
Tree of Life planetary CV matrix — ten sephirah outputs computed from real Keplerian orbital positions (Venus pentagram X/Y, Mercury retrograde triggers, lunar phase, planetary clocks), time warp up to x100,000,000, and a Da'at matrix mixer.
Eternal Eclipse Saros
Envelope and modulation generator — morphing shape bank, mouse-drawable screen with playhead, time warp and flux, 5 ms to 30 minutes.
Envelope generatorLow-frequency oscillatorFunction generator
Eternal Eclipse Liminal Vast Reverb
Lush stereo reverb with a modulated feedback delay network — from intimate rooms to the endless liminal vast.
Eternal Eclipse Moon Phase Distortion
Stereo distortion whose depth and character follow the real phase of the moon, with manual override and CV.
Eternal Eclipse Elemental Revelator
Four-element wavetable synth voice — a pentagram of AIR, WATER, EARTH, and FIRE oscillators with elemental-ring cross-modulation, opposing-pair ring mod, SPIRIT chord mode, 72 daemon algorithms, ladder lowpass filter, and stereo delay/diffusion.
Stochastic Telegraph Distribute
Tunable random voltage generator, with a large variety of random distributions.
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.
