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 sequencer: a chain of 8 phrases, each with its own length, key and tempo.
SignalFunctionSet Record
Auto-sampler: drives a voice across notes and velocities, then writes WAVs + .sfz.

HTTP bridge that lets Claude AI read and control your VCV Rack patch in real time. Connect it to Claude using the MCP Server + Skill available at https://www.patreon.com/c/nevertrustrobots
forsitan modulare bulla
Inspired by Hordijk's Blippoo Box: cross-modulating oscillators and runglers, 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: a tape loop that degrades a little more on every pass, with overdub.
forsitan modulare rete
Feedback integrator network: eight leaky nodes in a random mixing matrix, self-oscillating chaos.
forsitan modulare dræn
Drone synthesizer: two banks of 37 engines, each played from just a fundamental and a level.
forsitan modulare pellicula
Exploded 8-voice drum sampler: every voice's sample, pitch, decay and level on its own knob and CV.
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, diffused feedback delay network — from intimate rooms to the endless liminal vast, with infinite decay and freeze.
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.
Modular Mooch Wolfram
A multi-algorithmic sequencer capable of generating complex evolving patterns. Algorithms include one & two-dimensional cellular automata such as Conway's Game of Life. Sequences can be captured and looped, much like the Turing Machine.
Coalescent Bunnies
Predator-prey oscillator: prey and predator chase each other a quarter cycle apart. Lotka-Volterra and Rosenzweig-MacArthur modes.
Coalescent Operon
Three-phase oscillator on the repressilator gene circuit: three genes repressing each other in a ring, ~120 degrees out of phase
Cella Loudness CV
Loud and Loudness Meter expander with scaled overshoot and signed-error output modes
Forge Audio Analog LFO
Sub-audio oscillator with waveform morphing, analog character, and drift modeling
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.
