This is really simple stuff but I cant make it work. I want a set of 8 buttons in mainstage2 same as the synth keyboard. heres what I want... when i hit a button, it goes to a certain patch number (and lights up). when I hit another of the buttons, it goes to another defined patch number. simple. Can I do it? no HELP!

Is it possible to assign keyboard keys (ie the bottom C/C#/D) to patches so that when pressed, the patch changes accordingly. eg I am playing piano, I hit bottom C and it changes to Organ patch 10, C# changes to strings patch 12 etc.
