CFX4 Control Function Switcher

I'm gonna order one. I've exchanged a few e-mails back and forth with a dude who works for Axxess, and he's been really helpful answering questions. I would be using it with my Krank Revolution, and he told me I should get the "TRS Mod" when I order (which is free), so that all I will need in my case is any stereo cable to go from the switcher to the footswitch input on the back of my amp. I'm not sure exactly what kind of midi data or midi changes I will need to program in Pro Tools in order for the amp to change channels, but I imagine it will be quite easy.

That's what i was wondering about. I have Rolls Patchwork to do the swithing now but i need another free rackspace. the Axess unit takes up alot less space. i took a quick look at the manual and i thing you do need a midi input of some typ to program it, which may suck for on the fly stuff. if you get one let me know how well it works.
