pi-Stomp has always intended to be a platform. One of its main advantages over commercial units, is that it runs Linux, and thus can run additional software.
I just committed some minor software changes to allow the hardware to work independently of the recommended MOD software. So now, you can use pi-Stomp hardware with other audio plugin hosts!
You can even MIDI-map the pi-Stomp controls and footswitches to control effect parameters in the host.
I’ve tested two such hosts so far. They both work great.
Rakarack – an awesome (Free) guitar oriented virtual pedalboard

Carla – a Free, full featured modular audio host. It can run multiple plugin formats including LADSPA, DSSI, LV2, VST2, VST3 and AU, plus SF2 and SFZ sound font files!
