A revolutionary Rust-based Digital Audio Workstation featuring a unique three-view paradigm that seamlessly combines traditional DAW workflows with live performance capabilities and modular synthesis.
- Arrangement View: Traditional timeline-based production with automation
- Live View: Real-time performance interface with clip matrix and crossfader
- Node View: Visual modular patching with drag-and-drop signal routing
- Ultra-low latency (<1ms round-trip) real-time audio processing
- High-performance Rust pipeline for professional audio production
- Modular node system with 8 core audio node types
- SIMD-optimized DSP algorithms
- Full MIDI 2.0 protocol implementation with 32-bit precision
- MPE (MIDI Polyphonic Expression) for expressive control
- Per-note pitch bend and pressure sensitivity
- Advanced controller mapping with scriptable bindings
- SAI (Sonic AI): Generative audio synthesis from text prompts
- Stream Diffusion: Real-time audio generation and manipulation
- AI Stem Separation: Intelligent source separation for mixing
- Pattern Generation: AI-driven drum and bass pattern creation
- Stable clock synchronization with PTP support
- Advanced transport system with loop points and cue markers
- 8-track mixer with volume, pan, mute/solo controls
- Real-time effects and signal processing
- Web-based interface for browser access and collaboration
- Real-time bridge: UI ↔ Audio communication implemented with lock-free channels and feedback bus.
- Sample-accurate automation: Event queue exists, integration into audio callback is pending.
- Node graph mapping: Visual hex node view present; engine-side node creation/connection handling pending.
- Atomic parameters: Manager uses
Mutex<f32>; switch to atomic primitives for RT safety. - Deep time & polyspectral: Phase vocoder, time anchors, and FFT band-routing are roadmap items.
- Modu-Commit workflow: UI buttons exist; snapshot/branch engine support pending.
- Desktop app prioritized for demo/testing; web interface is secondary.
- Transport status integrated into bottom panel (playing/stopped, BPM, time).
- Audio Engine Monitor moved into main UI (non-floating) to avoid obstructing views.
- Views: Arrangement, Live, and Node views exist and render; wiring to engine is ongoing.
- DJ Decks: Planned as special plugins on Tracks 1–2 for Live view workflows.
- Browser/Mixer: Present as panels; content/functionality is being restored incrementally.
- Rust 1.75 or later
- Windows/macOS/Linux
- For web development: Node.js 16+ and wasm-pack

Modurust is built with a modular architecture separating concerns into distinct layers:
- Core Systems: DAW engine, transport, node graph, audio backend
- User Interface: Three-view UI system with web integration
- AI Tools: SAI, Stream Diffusion, stem separation
- Infrastructure: Plugin system, error handling, performance monitoring
- Oscillator (sine, square, sawtooth, triangle)
- Noise (white, pink, brown)
- Sampler (audio file playback)
- Granular (advanced granular synthesis)
- Filter (LPF, HPF, BPF, notch)
- Delay (digital delay with feedback)
- Reverb (algorithmic and convolution)
- Distortion (saturation and overdrive)
- Mixer (signal combining)
- Splitter (signal routing)
- Analyzer (spectrum/waveform display)
- MIDI-to-CV (MIDI to control voltage)
- 32-bit precision for ultra-fine control
- MPE support for expressive instruments
- Per-note parameters (pitch bend, pressure, timbre)
- Advanced controller mapping
- Sample-accurate timing
Generate audio from text descriptions:
let audio = sai.generate_audio("deep bass with reverb", 10.0, ¶ms).await?;Real-time audio manipulation:
let processed = stream_diffusion.process_audio(input, &settings).await?;Intelligent source separation:
let stems = stem_separator.separate_mix(audio_file).await?;Modurust DAW implements a revolutionary unified UI system that works seamlessly across platforms:
- Bevy Engine + egui: Native desktop performance with GPU acceleration
- High-performance rendering: 60fps with native look and feel
- Full system integration: Native windowing, audio, and hardware access
- Bevy WebAssembly: Same Bevy engine running in browsers
- WebGL rendering: Hardware-accelerated graphics in web browsers
- Progressive enhancement: Falls back to JavaScript UI if WebAssembly unavailable
- ✅ No UI duplication: One component system works everywhere
- ✅ Consistent behavior: Same logic across desktop and web
- ✅ Future-proof: Easy to add new platforms (mobile, VR, etc.)
