I've been using PD in os X with great joy for a year now but always on fairly straightforward grounds. Mostly using (modified) mouse and keyboard events to control audio prossessing. Recently I bought and put together a USB I/O ddevice (Velleman k8055). So now I'm looking for ways to let PD interact with it. Has anyone a idea where to start? I tried [keyboard] which does see it but does not output any data.
