\\Excellent idea EPU!
I also have 4 expansion boards installed (plus another 2 when I need them).
It would be WONDERFUL to be able just to say "show me the strings" or whatever.\\
The Korg Triton does it this way, in programs and in combi's.
It's amazing. Just press strings, and there's all your string sounds on your synth.
Want guitar? Click on guitars and there they are.
This is especially handy during sequence mode!
