I have ran pd on a raspberry controlling it with VNC Viewer over wifi quite successfully. Since I keep editing the Pd project I need to have access to the GUI, but I would prefer run it headless on the rpi since that would free up quite a bit of cpu.
Could you run Pd's GUI on one computer (i.e. my laptop) and Pd audio process headless on another (i.e. the RaspberryPi)? That would be so neat.
