OpenPatch 0.3.0 · build 10 combines Claude’s Patch Engine with the latest finished modular instruments and rack tools.

  • Patch Engine: choose genre, mood and texture, keep or vary the seed, and build in Reveal, Showtime or Instant mode. Includes an original C418-inspired piano mode and optional Light mode.
  • Five creative instruments: Tidal Functions, Frame Scene, Segment Garden, Event Fork and Rhythm Terrain. Source contracts and examples describe their supported behavior.
  • Rack tools: Organize with row settings, directional signal-path tracing, cable materials, seated black screws, recent-file access, room brightness and anchored DSP/MCP panels.
  • Visuals: Horizon, Phosphor, Ridges, Pulsar and Vector join Aurora, Spectrum, Waveform and Ferrofluid, with live GLSL editing.
  • Safer live construction: Save/Discard/Cancel protects edited documents; atomic document/revision/layout checks prevent asynchronous builds from adopting another client’s edits.
  • Desktop + CLI packages: macOS ARM64, Windows x64 and native Linux x64 for Steam Deck. Each includes examples, license notices and matching source links. Linux installs within your user account and preserves patches/settings.

Downloads

  • macOS: extract OpenPatch-macos-arm64.zip and move OpenPatch.app to Applications. The app is ad-hoc signed, not Developer ID signed or notarized.
  • Windows: extract OpenPatch-windows-x86_64.zip and run openpatch-desktop.exe. The bundled openpatch.exe is the CLI.
  • Steam Deck/Linux: extract OpenPatch-linux-x86_64.tar.gz, run ./install.sh in Desktop Mode and launch OpenPatch from the app menu. STEAM-DECK.txt includes Steam Input mapping and update instructions.

If upgrading from an older Patch Engine preview on Linux/Deck, run this installer once to install the new updater.

The packages include the CLI used for MCP control. macOS/Linux support attachment to an existing window; Windows currently uses openpatch-desktop.exe --mcp to launch a controlled window.

Qualification and scope

The final release gate passed on all three platforms: strict lint, refreshed complete desktop suites and doc tests, optimized binaries, archive/install/launch checks, 153 native Linux/Mesa captures, Python/MCP and browser integration. Unchanged CLI/Core correctness results were source-checked against the recorded prior run; build-provenance.json records that reference and each archive’s source tree. SHA256SUMS contains the download checksums. Automated checks are distinct from Windows audio-device and Steam Deck hardware/game-mode qualification; those device checks remain open. This is a development-stage synthesizer with 91 native module kinds, not complete VCV Rack parity. Existing VCV plugin binaries are not hosted. Unfinished Recall Random and experimental binary hosting are excluded.

Original OpenPatch code is MIT licensed; combined binaries include GPL processors and are distributed under GPL-3.0-or-later. Corresponding source: https://github.com/dexterlabs1/openpatch/tree/v0.3.0 .
