This project is an attempt to build a music studio similar to Ableton Live or Bitwig Studio.

The initial scope will be to output only MIDI events, with the simplest way to arrange clips.

All related to the UI is still very uncertain. I've been exploring several options but I don't feel like buying anyone of them yet. The one that I will be exploring consists on building the UI with Electron which would delegate to the core logic in rust. More information about the development of the idea here.

Suggestions are welcome.

This is a multi-project composed by:

• core: The core data model and logic.
• app-native: The native application that handles Audio/MIDI and uses the core.

More sub-projects will come depending on how I decide to build the UI.

You will need to install PortAudio before running the project as we're using the portaudio crate which has a dependency on it.

If you get this error:

error while loading shared libraries: libportaudio.so.2: cannot open shared object file: No such file or directory

then you should install libportaudio:

# ubuntu
sudo apt-get install libportaudio2

Finally, you can run the project:

cd app-native
cargo run --release

Tests can be run with:

cargo test

• core: Basic transport logic with accurate timing: play, stop, loop
• app-native: Allow MIDI configuration through studio.toml
• core: MIDI bus system
• core: Implement a basic metronome using MIDI notes
• core: Management of time and sync between different clocks: Audio, Midi, Host, Ticks
• app-native: Build MIDI output abstraction to send MIDI events to a device using CoreMIDI as an initial impl (in progress)
• core: Filling MIDI output buffers from the Song clips (initially choose one type of clip between pianoroll, step-sequencer, drum-box).
• Start exploring UI integration
