SignalFunctionSet Canon
Four arpeggiators reading one chord progression, wandering from it as Fugue does.
SignalFunctionSet Count
A narrow clock: six gate outputs, each a rate and a mask over one cycle of steps.
SignalFunctionSet Carillon
Bells joined by rods you draw: velocity and reach set how far a strike ripples.
GPaudio Clamp - Note Range Limiter
Limit Note Pitch (V/Oct) to a Range. Drop, limit or octave-shift out-of-range notes
GPaudio Chained Mixer Extended Channel
Extended Chained Mixer Channel for Mono and Stereo Inputs with Additional Aux Pre/Post Switching, Input Trim, Direct Outs and CV Inputs for Gain, Mute and Solo
GPaudio Triple Control Merge
Play your synth from three keyboards, MPE controllers or sequencers simultaneously
GPaudio Dual Control Merge
Play your synth from two keyboards, MPE controllers or sequencers simultaneously
Eternal Eclipse Eternal Eclipse
Resizable blank panel bearing the Eternal Eclipse corona. Drag either edge to set the width from 3 HP upward; the corona scales to fit.
Eternal Eclipse Syzygy
Orbital note generator — sixteen beads joined by a line drift around a field at speeds in powers of the golden ratio from a golden-angle sunflower, through five task figures (orbit, Lissajous, rose, star, sweep), with mass physics, wall bounce and mouse throw, an angular trigger arc, a fourteen-scale quantizer, and eight CV/gate pairs allocated Ansible-style; every parameter is a bare ±5 V input read once per EPOCH lap, made for Cosmic Clock.
SignalFunctionSet Flock
A murmuration as a microtonal granular voice: flocking birds, grains as their calls.
SignalFunctionSet Field
Nineteen related random voltages: one smooth random field read at nineteen points.
SignalFunctionSet PolyKit In
Expander for Kit: every input of every instrument as its own jack, 13 by 8.
Venom Random
Fully polyphonic implementation of the VCV RANDOM CV generator with independent shape controls
Clock generatorLow-frequency oscillatorPolyphonicRandomSample and hold
Infinite-Noise Envelope Phase Expander
2HP expander for ADR/ADSDR: phase gates (Attack, Decay, Sustain, Delay, Release, Idle) plus Rise, Steady, Fall. Idle can output phase position (0V to 10V).
Infinite-Noise ADSDR Envelope
6HP Attack-Decay-Sustain-Delay-Release envelope with attack/decay/release time and shape, and levels for Attack, Sustain and Release. Rate Chaos.
AmbientModules LunarFilter
Dual 12dB Polivoks-style multimode (Low-pass/Band-pass) filter with independent per-side CV, Link, a shared distortion stage with CV, and a stereo FX-insert loop (Send/Return, Blend, Master)
AmbientModules LunarDetector
External-source preamp with an Attack/Release envelope follower and a hysteresis gate detector
AmbientModules LunarPads
6-pad gate source for the drone voices (4 Lunar50Drone, 2 LunarPapaSrapa), momentary or latching, each pad's external gate input lets an external MIDI gate source trigger it alongside the mouse
AmbientModules LunarMixer
9-channel panoramic mixer with per-channel level and pan summed to a stereo output
AmbientModules LunarJoystick
Dual manual/CV position source (X/Y) with offset knobs and a switchable input range per axis, for use with an external MIDI CC-to-CV controller or as a manual fixed-voltage source
halfagiraf Constellate
Four-channel relational event memory and generative trigger processor with transition-confidence CV.
halfagiraf MOD1
Three independently scaled random CV outputs with internal or external clocking and smooth or stepped motion.
forsitan modulare vates
Stereo sample player with generated banks: modulate the sample choice and the rhythm falls out.
forsitan modulare artifex
Nine stereo effects sharing one feedback loop, with a pattern generator wired into them.
forsitan modulare aether
A faulty transmission line: audio to a pulse train on one clock, back through a PLL on another.
forsitan modulare materiae
Percussion from two square waves and the relation between them: logic, feedback, a ringing body.
forsitan modulare gradus
Eight rows of one knob and four moves: step the CV up or down, or jump to plus or minus it.
forsitan modulare scrupea
Chaotic bank: 16 oscillators into tuned feedback combs, modulating each other.
forsitan modulare cartilago
Gristleizer: LFO into a FET attenuator that never closes, or into a swept filter.
EffectVoltage-controlled amplifierRing modulatorFilterHardware clonePolyphonic
forsitan modulare tundo
Digital drum voice: six additive oscillators, morphing waves, prime spread, infinite folder.
forsitan modulare raucus
Big Muff Pi fuzz: four transistor stages, feedback diode clipping, scooped tone stack.
forsitan modulare caligo
Greyhole: a long modulated echo inside a nested allpass diffuser, with a patchable loop.
SignalFunctionSet Wheel
Hurdy-gurdy drone instrument: one wheel bows six strings, and the dog keeps time.
SignalFunctionSet Sigma
Additive voice: up to 64 sine partials, with velocity morphing between two spectra.
SignalFunctionSet Trace
A paper loop and four brushes: draw four CVs, or let the patch draw them.
ControllerLow-frequency oscillatorSequencerSample and holdUtility
AK Audio Looper
8x8 looper on the NINJAM jam clock (Ninjam expander): beat-quantized capture/launch/stop, free-running clips of any whole-beat length (tempo changes never touch committed audio), scenes, follow actions, auto-advance chains, overdub; takes persist on disk and in the patch. Beta: young and complex - expect occasional bugs.
Missing Mile Modular Doubleplus Pulses
Performance gate router for the Music Thing Turing Machine: eight channels, each routed to one of two OR/AND merge buses.
Freezer Labs Interactive Rhythm Composer
6 row drum sequencer with interactive style pattern generator, per-row shift and rush/drag controls and step probability.
stoermelder SPLICE-KIT
8x8 matrix patch-bay for creating and removing cables by pressing button pairs. Stores up to eight independent scenes per instance, with full MIDI control and feedback for playing your patch from a grid controller.
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.
