Omni is a professional Digital Audio Workstation written entirely in Rust — combining a lock-free, real-time audio engine with a GPU-accelerated interface (egui/eframe). Designed for producers who demand both reliability and performance, Omni delivers a complete music production environment on Linux and Windows.

Audio Engine
Omni's engine is built for zero-compromise real-time performance. The processing pipeline runs with SCHED_FIFO priority, memory-locked pages, FTZ/DAZ denormal protection, and a SIMD-optimized (f32x4) mixing bus. Plugin Delay Compensation (PDC) is automatic and DAG-aware. The engine never allocates on the audio thread.

Session View — Step Sequencer + Piano Roll + Euclidean Sequencer
The Session View offers a clip-launching workflow similar to modern loop-based DAWs. Each clip contains a 32-step pattern sequencer with dedicated lanes for pitch, velocity, gate length, probability, and performance modifiers. The full-featured Piano Roll editor includes scale-aware fold modes, velocity-to-brightness note coloring, snap grid quantization, marquee selection, copy/paste/duplicate, transpose, legato tools, and real-time note audition.

Arrangement View
A timeline-based arrangement editor with waveform display, clip split/resize/fade, drag-and-drop across tracks, loop regions, markers, and per-parameter automation lanes. Seamless crossfade switching between Session Arrangement modes.

Mixer
Per-track volume, pan, and trim controls with mute/solo/record arm. Send/return routing with pre- and post-fader sends. Master bus with dedicated FX chain. Real-time peak metering on every channel.

10 Built-in Professional Effects
Parametric EQ (3-band biquad) · Compressor (soft knee, auto-makeup, parallel mix, sidechain) · Stereo Delay (tempo-sync, ping-pong, LP feedback) · State Variable Filter (LP/HP/BP/Notch, zero-delay feedback) · Algorithmic Reverb (FDN architecture) · Chorus · Phaser · Saturator/Overdrive · Brickwall Limiter · Insert Chain.

Plugin Hosting
CLAP and VST3 plugins are hosted in isolated child processes via shared memory IPC for crash safety. Full parameter automation, state save/restore, and X11 editor window support are included.

Sampler Engine
Multi-format audio loading (WAV, MP3, FLAC, OGG via Symphonia), automatic high-quality resampling (Rubato, SincFixedIn, BlackmanHarris2), slice detection, MIDI-mapped triggering, and velocity layers.
