Python script for setting up a bidirectional bridge between REAPER's OSC control surface and web-based client implementations.
Includes a JavaScript port of https://github.com/lucianoiam/pyreaosc for interacting with the REAPER mixer through an easy to use object-oriented API.
- Transport play and record status
- Track volume, pan and mute
- FX bypass
- FX parameter values
- REAPER → Preferences → Control/OSC/web → Add → OSC → Mode "Local port"
- Run
