Quick APC question...

[thatMcFlyGuy]

I have an APC 20 and I was reading about how the APC 40 can expand/collapse grouped/drum racks and I was just wondering if the 20 can do this also. I tried holding down the shift button but nothing happens.

Is it a different control for the 20?

Does the 20 not support this feature?

Am I retarded?

Thanks in advanced
