max-lilypond

A Max package providing lilypond, a UI external that engraves GNU LilyPond music notation directly inside a Max patcher.

In development. The external is currently macOS-only (x64 and arm64); Windows support is planned.

How it works

The lilypond object shells out to an installed lilypond binary as a subprocess, has it write a cropped SVG, and draws that via Max's vector graphics.

Finding LilyPond

LilyPond is not bundled; the binary is discovered at render time.

Building

# Configure
cmake -B build           \
    -S .                 \
    -G Ninja             \
    -DCMAKE_BUILD_TYPE=Debug

# Build
cmake --build build

This assembles a complete Max package under build/package (with the external in build/package/externals/) rather than writing into the source tree. Override with -DMAX_SDK_PACKAGE_OUT_OF_TREE=OFF to build into the source tree instead.
