At 5 bills I'll be looking at the X-Touch compact first. I like the FP a lot, but I don't like that can't be used as a generic MIDI controller for stand-alone apps. I have it tweaked the way I want it, but having to use AZ Controller in Sonar to customize it is a PITA. No offense to AZ - without his tool I would be stuck. It's the same in Reaper. A 3rd party driver is req'd there to get the most out of the FP as well.
Might have changed with the FP-8. Maybe there is real MIDI out now ... time will tell.
