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 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.

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
Cella Loudness CV
Loud and Loudness Meter expander with scaled overshoot and signed-error output modes
THEREELPEET Phrasing
Phrasing and presence controller. Shapes rests, repeats, changes, and level-focused dynamics; intended to drive VCAs or Morph 4-style level CV inputs.
computerscare Mely Porge
Polyphonic input processor with 16 insert channels

No Such Device TrigGate
Create a gate from a start and stop trigger, such as the outputs on the MidiCV module.
stoermelder SIREN
Sample browser collaboration with Omri Cohen — browse, preview and drag WAV/FLAC/MP3 samples to other modules. Streams audio directly from disk with no full-file loading, making it practical for large sample libraries and long recordings. Also does repitching and creates endless loops.
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 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.
TNN1T1S GHOST MIX
Dedicated summing mixer for the Ghost drum kit. Twelve labeled inputs -- one per voice of the full kit (Kick, Snare, Rim, Clap, Tom Lo/Mid/Hi, Closed Hat, Open Hat, Crash, Ride) plus a MIXIN channel (the 909's external mix-in) -- each with a mute switch, summed to one MIX output. Per-voice level lives on the voices, so the mixer is a clean unity summer -- the whole kit on one master mix point, in the box.
TNN1T1S GHOST CTRL
Global state controller for the Ghost drum system. DEFAULT, ACCENT A, ACCENT B, and MASTER controls are broadcast to adjacent Ghost voices via the expander path. Hit-time events such as trigger and local/total accent gates are patched directly to each voice. Use GHOST CTRL to make the separate voices behave like one instrument.
Animatek APC40 CTRL
MIDI-to-CV bridge for Akai APC40 Track Control, Device Control, Cue and Crossfader CCs on MIDI channel 1, plus the 8 channel faders (CC7 on channels 1-8).

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 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 Meter
Time-signature-aware musical clock with bar/quarter/eighth/sixteenth/triplet outputs, CV-controllable time signature, and external clock sync
SignalFunctionSet Fugue X
Expander for Fugue — per-voice steps, range, sleep, probability, S&H mode, sorted CV outputs, and per-step trigger outputs
Ouroboros Industries Reset Helper
An utility to make it easier to reset sequencers from multiple sources. Converts gates to triggers, with a configurable "merge" time for incoming triggers
forsitan modulare limen
TCP + JSON interface for controlling VCV Rack from external tools (e.g. Emacs).
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.
