This is an example project for controlling a synth, programmed and compiled with Faust, through a Python script. The synth runs as a JACK client on Linux systems and the output is automatically recorded by jack_capture.

The following examples are written for Debian systems.

Faust Synth

This is a quick example for a subtractive synth, modified from the Faust documentation.

Get the Faust Compiler

The recent Faust compiler can be cloned from the repository:

https://github.com/grame-cncm/faust

Compile the Faust Code

With GUI (for testing):

faust2jaqt -osc subtractive_synth.dsp

Without GUI:

faust2jackconsole -osc subtractive_synth.dsp

This will create a binary:

subtractive_synth

OSC control

The synth listens to OSC commands on the defauilt Faust-UDP ports 5510, 5511 and 5512.

Run the Synth

• after starting the JACK server:

./subtractive_synth

Python Control

Install pythonosc

$ pip3 install pythonosc

Run Script

• after making sure that 'synth_control.py' is executable, run:

$ ./synth_control.py
