UnityMidiPlayer

Unity

A Unity plugin for importing and playing standard MIDI files (type 0 and 1) through MIDI outputs. Supports basic MIDI playback functionality and provides an API for procedural music generation using MIDI messages. The tool handles MIDI file import by converting .mid files to .txt format within Unity's asset system. It provides scheduling functions for precise timing control, including DSP-scheduled playback and sequential note triggering based on PPQ calculations. Note that older MIDI features like embedded lyrics are not supported and may cause import errors. The codebase originated from academic research in 2016 and the author acknowledges its rough implementation state.

16BarLogicGame

Unity · FMOD

16BarLogicGame is a Unity/FMOD adaptive music system built around a seven-state finite state machine (Idle, Explore, Combat, Anxiety, Epic, Win, Die). Each state drives a dedicated FMOD transition loop, and all state changes are held in a queue until the current bar boundary is reached — the system reads FMOD's timeline position, calculates bar length from BPM, and fires the transition at the exact bar edge. Priority locking prevents lower-intensity states from interrupting high-priority states (e.g., Anxiety blocks queued Explore or Combat transitions until it resolves). Custom timers govern nuanced exit conditions, such as delaying Combat exit until a configurable post-encounter window elapses. The repo includes a playable Unity scene with combat and spawner scaffolding for exercising all state transitions. It targets Unity 2022.3 with FMOD Studio integration.

Motif is a browser-based adaptive soundtrack workstation aimed at game composers who need structured, intentional score authoring rather than procedural generation. It covers the full composition pipeline: clip sequencing with music-theory transforms, multi-oscillator synthesis with LFO modulation, sample instrument building, scene layering with intensity curves, and automation lanes. The tool handles the game-integration layer directly: trigger bindings map game state to scenes, deterministic resolution picks the correct cue at runtime, and a runtime-pack exporter serializes the project for engine consumption. MIDI import/export and 24/32-bit WAV export at standard sample rates are also included. Everything runs client-side in the browser with no server, no telemetry, and no cloud sync. The project is a TypeScript monorepo of 16 npm packages under the @motif-studio scope, tested with 1,116 unit tests covering schema validation, playback, synthesis, effects, and studio integration.

zzfxm-rs

Standalone · Engine-agnostic

zzfxm-rs is an unofficial Rust port of ZzFXM, the minimal tracker-style music renderer originally written in JavaScript by Keith Clark and Frank Force. It takes ZzFX instrument definitions, reusable patterns, a sequence, and a BPM and produces stereo f32 PCM output, leaving playback entirely to the caller. The library targets ZzFXM 2.0.3 compatibility, covering beat timing, channel mixing, stereo panning, fractional note attenuation, end-of-note fades, instrument/note sample caching, and legacy ZzFX instrument behavior. It uses zzfx-rs for instrument synthesis. It also supports loading the compact nested-array format used by JavaScript ZzFXM songs, including JavaScript-style sparse array holes represented as None. Useful for embedding chiptune-style music in Rust games or demos where binary size and dependency count matter. Caller-provided randomness allows deterministic rendering, and optional Serde support covers serialization needs. Not yet published to crates.io; installed directly from GitHub.
