Java MIDI API

Hey there,

anyone got some experience with the Java MIDI API?
I'm working on something like virtual Piano at the moment. But it's not only supposed to be a piano you should be able to choose the instrument you want to play.
And here the trouble starts. I know how to retrieve the soundbank from the synthesizer but i just don't get how to change the instrument that's played.

Any tipps or good tutorials on this specific topic? I already read the Oracle tutorial but it didn't really help.

Although that looks quite interesting something a little less general would be appreciated.

go choke on a buttplug, faggot

I know fuck all about Java's MIDI API, but program change messages is the intended way to change the program(!).

why would anyone use java for something which can be done with a avr mcu?
or anything else for that matter...

          (else "YOU LOSE FAGGOTFACE!!!")))

    (rps* n (rps-val (random 3))))

(list (rps 'r) (rps 'p) (rps 's))
