I use my AI module to insert an instrument track (actually, you can use any CMC module, but with AI you don’t have to hit the SHIFT key to access the programmable buttons.) I just press one of the programmable buttons and add an instrument track, but then I still have to select the instrument with the mouse. And yeah, that could be much improved if I could, for example, select the instrument with the AI wheel and then click (on the wheel) when I reach the one I need.
