Hello Juneau,
I would like to direct your attention to page 148 of the Genos Reference Manual.
As you will see, it is possible to change what each CC is doing on the Genos, and change the part(s) it is applied to.
So what do PC1-4 correspond to ? Whatever you set it as.
I think this is both a blessing an a curse. Blessing in the extra flexibility it provides. Curse in that it makes things more complicated.
I tried an FCB1010 for a while, but I decided to go Midi Bass pedals, and there wasn't enough room for both. Unfortunately, it was a while ago, but I do remember programming the 1010 by pushing the on-board buttons, not using a computer. If my memory is correct, I set the 1010 to send out CC7 for the expression pedal, and CC1 for the other pedal. The rest of the buttons on the 1010 I set to send a note on/off, and used the Genos screen from page 148 to set what that note did.
Hope that's somewhat helpful.
Good luck
Adam Parker
