Pro Wave

ProWave is an open-source music production DAW in pure Rust, with a look and workflow modelled on Apple's Logic Pro. It is drawn entirely with egui and plays audio through cpal: no Electron, no JUCE.

Status: early development. Tracks, MIDI and audio regions, MIDI and audio recording, the Piano Roll, the Mixer with effects and automation, the Library and the built-in synthesizer work; most of Logic's instruments and many editing commands are still to come. ROADMAP.md has the full plan and resume.md a detailed status of what works today.

Piano Roll with quantize and velocity lane	Playback with live channel meters

ProWave is an independent project. It is not affiliated with, sponsored by or endorsed by Apple Inc. Logic Pro is a trademark of Apple Inc., used here only to describe the workflow ProWave follows. ProWave contains no Apple code, artwork or sounds.

How much of the app works today, counted from the source: a menu entry is done when it can be used, and a roadmap item when it is ticked in ROADMAP.md. Run cargo xtask status to update this section.

• Engine (prowave-engine): sample-accurate transport with cycle, metronome and a tempo map; a lock-free command queue between UI and audio thread, with no allocations on the audio thread; a built-in subtractive synthesizer with drum-kit modes (48 voices); per-track volume, pan, mute, solo and meters; WAV, AIFF, FLAC, MP3 and CAF regions streamed from disk.
• Tracks area: ruler, cycle band, playhead, track headers, MIDI and audio regions with waveforms; move, repeat and delete regions with snapping; per-track heights.
• Piano Roll: draw, select, move, resize and delete notes; quantize (with strength and swing), scale quantize, velocity lane, playable keyboard.
• Mixer: channel strips with sends, pan, faders and meters; Library patches that change a track's instrument and sound; Region and Track inspectors applied non-destructively.
• Projects: .prowave files (a zip with project.json and the audio in media/).
• Time signatures: any signature, including compound meters such as 6/8 and 7/8.

Get the latest build from the Releases page (each version is a pre-release while Pro Wave is in early development):

The files are not code signed, so Windows SmartScreen and macOS Gatekeeper warn before running them; the release notes say how to continue. Linux install steps for every format, the libraries needed and troubleshooting are in dist/README-linux.txt. The Linux and macOS packages have not been tested on real hardware yet; reports are welcome.

Pushing a version tag such as v0.1.2 runs the Release builds workflow, which builds every package, test-installs the Linux ones and publishes the Release. Running it by hand from the Actions tab builds the packages as workflow artifacts without publishing.

cargo run --release -p prowave-app                  # the app
cargo run --release -p prowave-app -- song.prowave   # open a project
cargo run --release -p prowave-app -- drums.wav      # new project, import audio files
cargo run --release -p prowave-app -- --play         # start playing right away
cargo run --release -p prowave-app -- --piano        # open the Piano Roll on start
cargo run -p prowave-engine --example beep           # 440 Hz test tone, reports output latency

Linux uses Ctrl where macOS uses Cmd: Space plays and stops, Ctrl+N/O/S new, open and save, Ctrl+R repeats a region, and Y, I and X toggle the Library, Inspector and Mixer.

Rust stable is required. On Linux, install ALSA's development files and pkg-config first:

cargo build --release -p prowave-app   # the program is target/release/prowave
cargo xtask check                      # fmt, clippy -D warnings, tests, no-alloc check, cargo-deny, wasm check
