    #moondsp CLAP prototype

    This directory contains the native CLAP bring-up scaffold.

    • clap_payload.mbt is a MoonBit native main package used to emit generated C for the clap_host/ primitive handle bridge.
    • moondsp_clap.c is the C CLAP ABI shim, compiled against the vendored official CLAP 1.2.8 headers in ../third_party/clap/.
    • moondsp_clap_moonbit.h is generated from the native payload C and maps the shim's stable mb_engine_* aliases to the current MoonBit-mangled clap_host symbols.

    Build the Linux prototype:

    scripts/build-clap-prototype.sh

    Cross-build a Windows x86_64 prototype for Windows CLAP hosts such as Bitwig Studio with MinGW-w64:

    scripts/build-clap-prototype-windows.sh

    Install the Windows build for the current user with:

    %LOCALAPPDATA%\Programs\Common\CLAP\moondsp-synth.clap

    Run the local dlopen/process smoke test:

    scripts/smoke-clap-prototype.sh

    Regenerate the MoonBit bridge header after a MoonBit toolchain or package-name change:

    moon build --target native --release clap_plugin
scripts/generate-clap-moonbit-header.sh \
  _build/native/release/build/clap_plugin/clap_plugin.c \
  clap_plugin/moondsp_clap_moonbit.h

    Run the pinned clap-validator check:

    scripts/validate-clap-prototype.sh

    Outputs:

    _build/native/release/clap/moondsp-synth.clap   # Linux ELF shared object
_build/windows/release/clap/moondsp-synth.clap # Windows x86_64 PE DLL

    The Windows build has loaded in Bitwig Studio 6.0.6; see ../docs/development/2026-06-06-clap-bitwig-windows-host-load.md. Before production use, complete the audio-thread allocation audit.
