Install s3g-dsp CLAP Plugins

The 0.11.0-pre release has Apple silicon (arm64) Mac and experimental Windows x64 packages for REAPER. The Mac package is not notarized, so macOS requires one Gatekeeper approval for its installer. Windows uses manual folder installation.

Download and Install

1. Quit REAPER, download the macOS CLAP zip from the GitHub releases page, and unzip it.
2. Double-click Install s3g-dsp CLAPs.command in the unzipped package.
3. If macOS blocks it, click OK, open System Settings > Privacy & Security, and choose Open Anyway. Confirm Open and authenticate if asked. This option is available for about one hour after the blocked launch.
4. If prompted, allow Terminal to access the downloaded package, then wait for installation to finish.
5. Start REAPER and rescan CLAP plugins if the new builds do not appear automatically.

See Apple's Open a Mac app from an unknown developer for the same approval process. If a binary is unavailable, see Building From Source.

Install Location and Safety

~/Library/Audio/Plug-Ins/CLAP/s3g-dsp/

Back up your current plug-ins before upgrading. The installer replaces current canonical bundles and moves verified renamed/retired aliases—including copies in the former top-level CLAP location—to a timestamped backup. Other CLAP products are untouched.

Manual Installation

Use this only for a fresh manual install; it cannot migrate older top-level copies or retire renamed aliases. In Terminal, type cd followed by a space, drag the unzipped s3g-dsp-macos-clap-0.11.0-pre folder from Finder into the Terminal window, and press Return. Then run:

destination="$HOME/Library/Audio/Plug-Ins/CLAP/s3g-dsp"
mkdir -p "$destination"
for bundle in ./*.clap; do
  installed="$destination/$(basename "$bundle")"
  ditto "$bundle" "$installed"
  xattr -drs com.apple.quarantine "$installed"
done

Tracker Development Builds

Tracker is now a CLAP-only MIDI plug-in; there is no current Tracker standalone app to install. A newer development build may have features not yet in the packaged pre-release. On Mac, quit REAPER and preserve the previous bundle before replacing it with the complete s3g_tracker.clap bundle in the location above. Keep only one installed Tracker copy in the host's search paths, then restart REAPER.

The separate Windows x64 Tracker package is a test build, not an accepted release. Copy its complete folder to a location in REAPER's CLAP search paths, keeping s3g_tracker.clap beside Resources and retaining the license notices. Run the included run-windows-check.cmd where supplied; it checks the plug-in without installing it and does not replace host testing. Do not use the Mac installer for Windows.

The bundled fonts need no system-wide installation. Mac font resources live inside the CLAP bundle; Windows resources stay in the sibling Resources folder. See Tracker platforms and fonts and Tracker source builds for details.

Experimental Windows x64 Suite

The s3g-dsp-windows-x64-clap-0.11.0-pre-experimental.zip package contains 125 CLAP files exposing 132 plug-in descriptors, including Tracker with VIEW Live Code commands. Ambi Energy is the only excluded inventory entry; its renderer prototype is not a CLAP. This is an experimental prerelease, not a stable Windows release. Testing has used Windows 10 x64 and REAPER; Windows 11 is not yet validated. The earlier timestamped s3g-dsp-windows-clap-suite-x64-test-*.zip files are development snapshots.

1. Save your work and quit REAPER, plus Max and Live if open. Extract the entire ZIP to a fresh folder.
2. Move older s3g-dsp copies outside all host CLAP scan paths, retaining them as backups. Do not merge the new collection into an old folder.
3. Copy the extracted folder's complete contents to a fresh %COMMONPROGRAMFILES%\CLAP\s3g-dsp folder (usually C:\Program Files\Common Files\CLAP\s3g-dsp in Explorer). Windows may ask for administrator permission. Keep the .clap files beside the shared Resources directory, with fonts, atlases, and license notices intact.
4. In REAPER, open Preferences > Plug-ins > LV2/CLAP, confirm %COMMONPROGRAMFILES%\CLAP is in the CLAP path list, rescan, and test in a disposable project. Use conservative monitoring levels, especially with sound generators and feedback processors.

This Common Files location is normally searched by both REAPER and s3g.clap~ in Max for Live. If you cannot use it, install under %LOCALAPPDATA%\Programs\Common\CLAP\s3g-dsp instead and add %LOCALAPPDATA%\Programs\Common\CLAP to REAPER's CLAP path list. The per-user path REAPER normally lists, %APPDATA%\CLAP, is not one of s3g.clap~'s built-in Windows search roots. Keep only one active copy across these locations.

PLUGIN_MANIFEST.tsv lists the expected plug-ins. SHA256SUMS.txt covers the extracted payload; the adjacent ZIP checksum covers the archive. run-windows-check.cmd checks Tracker only and does not install anything. Font installation is unnecessary. Do not use the Mac installer or merge only selected files into an older pilot folder. For reproducible builds, see Consolidated Windows Test Package.

If a Plugin Does Not Appear

• On Mac, confirm that its complete .clap bundle is in ~/Library/Audio/Plug-Ins/CLAP/s3g-dsp/. On Windows, confirm its .clap file and shared Resources folder are under the chosen CLAP path above.
• Check REAPER's CLAP path list, rescan, then restart the host. On Windows, also check for an older copy in another scanned folder.
• On Mac, if REAPER shows per-plugin Gatekeeper dialogs or duplicate names, quit REAPER and rerun the packaged installer. If the installer itself is blocked, repeat the Open Anyway step within one hour.

For routing after installation, see Multichannel, Stereo Listening, or Ambisonics.

Using these CLAPs through Max for Live requires the separate Max host and Live devices. Install the CLAPs first, then follow the Ableton Live setup guide; the CLAP installer does not install .amxd devices.
