Vonk — VCV Rack Modules

Modules — 9 available

Avalanche

Granular Delay ⚠ Alpha

This module is currently in alpha. Expect bugs and breaking changes — feedback and bug reports are welcome via GitHub.

Captures incoming audio into a buffer and plays it back as a cloud of overlapping grains. Each grain has its own envelope, enabling textures that range from subtle thickening to full granular cloudscapes. Pitch shifting, freezing, and reverse playback are all available per grain.

BitBoy

Oscillator Beta

GitHub

A classic 8-bit style oscillator delivering crunchy digital tones with authentic bit-crushing and NES-style noise generation. Four waveforms cover the full range of lo-fi character from punchy square basses to gritty digital noise.

MotherFuzzer

Distortion Beta

GitHub

A rich, musical fuzz and distortion effect with intuitive Drive, Tone, and Volume controls. Soft clipping drive from 1× to 100× paired with a low-pass tone control makes it equally at home on synth basses, leads, or drums. CV inputs on all three parameters open it up for dynamic modulation.

SubGate8

Gate Sequencer Beta

GitHub

An 8-step gate sequencer with 4 subdivisions per step, giving 32 individually togglable triggers. Swing and gate length controls add groove and expressiveness. Compact and performance-friendly, it syncs to external clocks and fires an end-of-cycle pulse for chaining.

SubGate16

Gate Sequencer ⚠ Alpha

GitHub

A 16-step gate sequencer with 4 subdivisions per step, giving 64 individually togglable triggers. The expanded step count allows longer, more complex rhythmic patterns while retaining the same swing, gate length, and clock sync features as SubGate8.

This module is currently in alpha. Expect bugs and breaking changes — feedback and bug reports are welcome via GitHub.

Burst Sequencer Beta

GitHub

A 16-step sequencer where each step is a self-contained burst generator. Instead of a single gate per clock, each step fires a burst of evenly-spaced gates with independent control over count, length, probability, and speed relative to the clock.

Utility Beta

GitHub

A 4-channel variable gate length module. Takes gate or trigger inputs and re-emits each as a gate of a fixed, independently-set length — from 1ms to 2 seconds. Each channel retriggers cleanly on every rising edge.

Riddim

Drum Sequencer ⚠ Alpha

GitHub

A 7-voice, 16-step drum pattern sequencer with per-voice gate outputs and a dedicated fill mode. Swing, clock division, and one-click pattern randomization make it easy to build and vary grooves live. The fill pattern is independent of the main pattern and can be randomized at any time.

This module is currently in alpha. Expect bugs and breaking changes — feedback and bug reports are welcome via GitHub.

Burst Generator ⚠ Alpha

GitHub

A polyphonic gate burst generator that turns a single trigger into a randomised cluster of gates spread across a clock-synced window. Each polyphonic channel gets its own independent burst engine and random state, producing rhythmically coherent but unpredictable fills, rolls, and ornaments.

This module is currently in alpha. Expect bugs and breaking changes — feedback and bug reports are welcome via GitHub.

Installation

Install the VCV Rack SDK & C++ toolchain

Download the VCV Rack SDK and set up a C++ compiler for your platform:

Windows — Install MSYS2, then open the MSYS2 terminal and run pacman -S mingw-w64-x86_64-toolchain make to install the MinGW compiler and make.
macOS — Run xcode-select --install in Terminal to install the Xcode Command Line Tools, which includes clang and make.
Linux — Install GCC and make via your package manager, e.g. sudo apt install build-essential on Ubuntu/Debian.

Clone the module repository

Clone the GitHub repo for the module you want and navigate into its directory.

git clone https://github.com/grant-pie/<module-name>
cd <module-name>

Build and install

Run the install target. This compiles the plugin and copies it into your Rack plugins folder.

make install

Launch VCV Rack

Start or restart VCV Rack. The module will appear in the module browser under Vonk.
