After few test on the pisound card with great results I'd like to present you my project : a looper pedal based on pisound and sooperlooper.
I've already manage to use a cheap usb pedal board (in french) (in english) to talk to sooperlooper (rec/play) via pure data.
Now, I'd like to send informations feedback from sooperlooper to a phone or a tablet via wifi with OSC.
Meanwhile, I try to build a small and stable linux image with buildroot to drive audio with pisound the best that i can.
If everything goes well I'll try to make a standalone pedal board with a teensy to interface the raspberry pi, sooperlooper and pisound!
I'll feed the topic as I can...
