I am making a patch for the Wii Rock Band controller. I have it almost done, I made the strum bar an open note and the five buttons the next five semitones. I have the toggle switch changing between five audio waveforms (Sine, Saw, Triangle, Square, and an attempt at mimicking a real string.) What I want to do is have the plus and minus buttons change the output sound of the strum and buttons by adding and subtracting, respectively, six midi notes.
I would also like to know how to do this to switch samples output from a key press.
Also, the solo buttons (the smaller buttons farther down the neck) are read by the computer as the same as the five buttons, but at the same time all of them are also triggering another button. (ex: Green Solo button = btn_1 and btn_6) I would like to know how I can make it so btn_6 will read the other btn_1-5 and make the note output for btn_6 a perfect fifth above that.
If anyone can give me any ideas to help that'd be great, thanks.
