I'm aiming to create a Korg Wavedrum-like project. The idea is to have a tensioned drum head miked with two piezo contact mics (one at center and one at edge) feeding into the Cirrus card so the signals can be processed by PD into something more interesting. I'm not talking about just using the piezos as triggers: the audio they capture can be part of the final sound.
I know people have said the RPi is not a good platform for DSP, but I think for this application it will be good enough. The problem I'm having right now is with how to set up a real-time kernel on the RPi 2, which is what I'd like to use as it has more RAM and processor power. I've tried Google and the search here, but didn't find anything I understood. Is this possible, and does anyone know where some good information can be found on it? It's been a long time since I've used Linux, so I'm really rusty at the moment.
Thank you very much for your help.
