Work in progress: a small text-based DSL for MIDI sequencing. Songs are written as plain-text source that defines named timelines of notes and references between them; the runtime parses the source, walks the resulting tree against an internal or DAW-driven clock, and emits MIDI to a chosen output device.

• Odin — install via the Odin install guide.
• PortMIDI (via Odin's vendor:portmidi): brew install portmidi on macOS.
• Raylib ships with the Odin compiler (vendor:raylib); no extra install.

odin build source -out:build/midiseq -debug
