I am thinking about replacing my E-MU Xboard 49 with an Akai MPK49 because (1) The Akai supports a sustain and expression pedal at the same time, which Strad requires; (2) It has sliders in addition to knobs, which I would like to use with Ableton Live; (3) It has percussion pads.

To help me make up my mind, can anyone tell me of any problems that the MPK49 has with any of the Garritan libraries?
