Roadmap
Phase 0 — Baseline
Inspect repository/toolchain, verify Makefile and minimal executable, document dependencies. No system changes without permission.
Phase 1 — C core and offline processing
Graph data structures, validation, cycle detection, topological ordering, preallocated buffers, test oscillator, gain and offline render tests.
Phase 2 — Real-time backend
Choose and implement a Linux backend. Document callback semantics, start/stop, device errors, shutdown, and safe graph publication.
Phase 3 — FLTK shell
Main window, transport controls, view switching, backend status, clean startup and shutdown through the C API.
Phase 4 — Modular editor
Draw nodes/ports/edges; create, move and connect nodes; reject invalid edges; safely submit edits to the C core.
Phase 5 — Project and sequencer
Versioned persistence, stable IDs, tracks, clips, timeline, selection, zoom, scrolling, and transport synchronization.
Phase 6 — Audio clips and recording
Audio import/playback, recording through bounded buffers, missing-asset handling, no file I/O in callbacks.
Phase 7 — MIDI and instrument
MIDI input/events/clips, simple internal instrument, note-off/panic handling, then a basic piano roll.
Phase 8 — Mixer and editing
Gain/pan, meters, mute/solo, automation, undo/redo, keyboard workflow.
Phase 9 — Extensibility and release
Native node API, evaluate plugin hosting, licensing review, packaging, installation tests, performance and recovery tests.
Do not skip phases without documenting why and preserving acceptance criteria.
