GPO 4 and Yamaha Organ: don´t know how to use them together
I am new to GPO 4, and mainly use it with Sibelius, but I would like, also, to use it with the Aria Player to play with a keyboard. I have a Yamaha Organ (PSR413), and don´t find how to:
- Change channels from the keyboard. (sticks to channel 1).
- Make the Wheel work as GPO 4 should treat it (it keeps modulating the sound, as when using the organ independently).
I looked on the Yamaha documentation, but couldn´t find the answer. Perhaps here, with more experienced people, I can get some help.
