Routing audio into an ofxPd application on raspberry pi


I’ve got my ofxPd applications running on raspberry pi, now I’m trying to route audio from other applications into an ofxPd application.

I have Patchage installed, but my application won’t show up in there, so when my application attempts to load I get an RtApiALSA error. Am I barking up the right tree here, or should I be using another approach?

Many thanks!
