I've had my pi for about a week now, trying to come up with some brilliant project when it hit me: the Pi would be perfect for running a drum machine.
Background: I have an Alesis DM10 which supports MIDI over USB and also has a documented history of working with Hydrogen. While I consider myself fluent in computers as a whole, I haven't spent much time with Linux, so please forgive me if I ask silly questions while trying to learn
I got Hydrogen running on Raspian Wheezy and I got the Pi to communicate with my MIDI input, but so far I have been completely unable to get any sound out
of the Pi. The closest I have come is some painful-sounding popping and clicking coming out the analog jack.
My ultimate dream is to have some sort of USB or S/PDIF box that will give me multiple sets of outputs (5+ outputs would be divine; if they were balanced it would be even better) for the different drum voices. This is still a bit of a far-off dream, though, since I can't even get the integrated audio working!
Does anyone have any suggestions on how to get Hydrogen to output audio? And, with my dream in mind, what is the best audio subsystem to use? JACK seems like it is built for what I want, but I haven't found anybody who had success getting JACK running on the Pi yet.
I've done some basic troubleshooting; I can play audio using aplay and omxplayer through both the analog output and the HDMI port.
Sorry if I've been unclear about anything. I'll be more than happy to clarify if I can. Thanks!
