Melodom

The DAW you already know.

Melodom is a free, open-source digital audio workstation that works the way Pro Tools users expect. Record, edit, mix and bounce on macOS.

Melodom's Edit window with a nine-track session: drums, bass, pad, keys and lead, a reverb aux and a master fader
The Edit window with the built-in demo song. Every sound in it is synthesised by Melodom itself.

Edit

Audio and MIDI, with playlists and comping, fades, clip gain, Beat Detective and undo for everything.

Mix

Inserts, sends, busses and VCAs, automation written live from the faders, and automatic delay compensation.

Record

Punch in, loop record and monitor through the full channel strip. Autosave brings your work back after a crash.

Plug-ins

Original effects and instruments built in, and your own CLAP, VST3 and Audio Units with their own editors.

Go further

Video with timecode burn-in, surround up to 9.1.6 and Ambisonics, and a Score Editor for notation.

Script it

Every action is a command you can run from the command line or hand to an AI agent.

Get started

Download Melodom 0.7.0 for macOS 11 or later (Apple silicon and Intel), open the DMG and drag Melodom to Applications. Windows and Linux builds will follow once they've been tested.

It isn't notarized yet, so macOS stops it the first time: try to open it once, then click Open Anyway in System Settings › Privacy & Security.

Then press Space to play, ⌘= to switch between Edit and Mix, and open Setup › Keyboard Shortcuts for the rest.

Or build it from source on a Mac, with Rust 1.95 or later:

git clone https://github.com/grovebit/melodom
cd melodom
cargo run --release -p soundcraft -- --demo

Melodom is pre-alpha. Recording, editing, mixing and bouncing work end to end, but it can't exchange sessions with Pro Tools yet, and it isn't ready for paid work. Bug reports and wishes are welcome in the issues.
