Hy!
I connect the Audya with USB midi and it work .But when I play the second midi it go crazy.The led's of sound buttons were runing on keybord and the screen was trying to follow them with the menu of sound.
Maybe I should put the Sys ex off on the audya or it's something else.
And is very noisy when connect the usb midi to the keybord.Even with the main volume 0.
