Hello there. I need to make a sketch in processing to play different instruments (gm midi) when i press different keys on the computer keyboard using the soundcipher library. I have made a sketch that play a note when a key is pressed but is always a piano sound. How i can have different sounds, ie Acoustic Bass for a key 's' pressed and a electric piano when a key 'f' is pressed? I know it must have something to do with program change but i could not figure it out by myself. Thanks for any help!!!
