A granular synthesizer with 8 individual play heads, built as a cmajor patch with a vue.js UI.
Drop an audio file into the synth and each head can independently scan its own region of the shared buffer, with its own position, motion, and grain parameters. The heads run simultaneously, creating layered granular textures from a single source recording.
Use it as a MIDI-playable instrument or let it free-run as an evolving drone. The editor visualizes the buffer, loop regions, and head positions so you can see how the grains are moving through the source.

Download CloudChamber-<version>.zip from the releases, unzip it, and drag
CloudChamber.cmajorpatch into the Cmajor plugin.
pnpm install
pnpm build
dist/ is then the patch bundle — CloudChamber.cmajorpatch, CloudChamber.cmajor and the
compiled main.js view — ready to load in a host.
The CLAP headers are not part of cmajor, so clone them once next to this project:
git clone --depth 1 https://github.com/free-audio/clap.git ../clap
pnpm run build-clap then builds the ui and generates a self-contained CLAP plugin project into
dist-clap, with the include path to the CLAP headers already baked into its CMakeLists (the Vue
gui is embedded into the generated C++). Open that folder in your IDE, or build it from the command
line:
cmake -S dist-clap -B dist-clap/build
cmake --build dist-clap/build --config Release
