Meanwhile..... back to the OP's & Chuck's question. The X32 compact (and producer) have 2 physical banks of 8 faders. The original design (v1.x firmware) was the left faders were the individual channel faders and switched via buttons providing 8 layers. The right bank of faders was setup the same as the full x32 with 4 layers: DCA, bus 1-8, bus 9-16 and the matrix selection. After using this for a couple of minutes you want to use the right bank for channel faders and Behringer added that functionality in v2.x firmware. Now if you press the 1-8 and the 9-16 buttons at the same time you end up with channels 1-8 on the left and 9-16 on the right. Same thing with 17-24 and 25-32 button functionality.
Freshly coming from the analog world I went with the original x32 (aka "full") which has 16 faders on the left and 8 on the right, each with 4 layers. Channel faders on the left with DCAs and busses on the right make life simpler and my brain doesn't hurt.
