This is my first time doing this.

I got GPO4 last night and here is my problem
Ok, I have an M-Audio Keystation 61es.
1. I go to channel one and select violin, and go to channel 2 select piano.
2. Click on channel 1 and play keys on the midi keyboard I get the correct sound (the violin)
3. Click on channel 2 where I have the piano, play keys on the midi keyboard, I do not get the piano sound, I still get the violin sound. This only happens when I play from the midi keyboard.

If I use my mouse and click on the virtual keyboard in Aria everything is normal, All channels with their selected sound are ok (1-16).

It seems like my midi keyboard only recognizes only the first channel in Aria.

How do I get to play the different selected sounds from channel 2 -16 using my midi keyboard.

Thank you.
