Patchrrr is a minimalist Python based patchbay for Jack audio and ALSA MIDI on Linux. It takes lists of input/output pairs and tries to keep them connected at all times.
This project was created for a headless audio processing setup, with no X or Wayland present.
- 800 lines of Python with no dependencies (thanks to
ctypes) - Easy install — just download the single file
- Linux only
- Dynamic patching, including the ability to disconnect clients
- Run in the background so the main thread isn't blocked
- Support for Jack MIDI (assuming it doesn't just work already)
Just copy or download the patchrrr.py file. You can then use it in two ways:
- Edit the examples at the top to specify the clients you want to patch together, then run:
python patchrrr.py
- Import
patchrrrinto your own file and create an instance of the manager class
Patchrrr is designed around blocking IO, threads, and queues. It should be fairly lightweight in terms of resource consumption, but running super fast isn't the main goal.
