- **Modular engine first:** sequencer, instruments, effects, mixers and I/O are nodes in one processing graph.
- **C core:** project model, graph, DSP and audio engine are implemented in C.
- **Optional JUCE GUI:** build `xtc-juce` with `-DXTC_BUILD_JUCE_GUI=ON -DXTC_JUCE_ROOT=/path/to/JUCE`. Keep or disable FLTK independently with `XTC_BUILD_GUI`. See [the JUCE frontend](src/gui/JUCE/README.md) for build/run instructions and SDK licensing.
- **FLTK/C++ GUI:** C++ is confined to the graphical interface and calls the core through a C API. The sequencer coordinates nested ruler, track, header, clip and velocity widgets; see [GUI ownership](docs/ARCHITECTURE.md#sequencer-widget-ownership).
- **Linux first:** keep backend-specific details behind an interface.
- **Small increments:** build and test each milestone before adding features.

## Build
Requirements: CMake 3.25+, a C99 compiler, Python 3.12+ and a build backend such as Ninja or Unix Makefiles. The default optional GUI needs C++17 and FLTK; a separately selectable JUCE frontend uses an external JUCE SDK; JACK and LADSPA development files enable their optional integrations.

Override `BUILD_DIR`, `BUILD_TYPE` or `JOBS` as needed, for example `make BUILD_DIR=build/release BUILD_TYPE=Release JOBS=8`. Pass additional options with `CMAKE_ARGS` and `CTEST_ARGS`. CMake remains the authoritative build system.
This builds `libxtc.a`, the headless `xtc-check`, tests, examples and the FLTK application when available. Live JACK tests are opt-in. Use `-DXTC_BUILD_GUI=OFF -DXTC_BUILD_JUCE_GUI=OFF` for the C-only build, or the `debug`, `release`, `minimal` and `sanitize` presets for separate configurations. See [docs/BUILD.md](docs/BUILD.md) for options, focused tests, installation and IDE setup. [Phase 108](docs/ROADMAP.md#phase-108--complete-cmake-build-migration) records the CMake migration.
