I have the Fast Track Pro. The Fast Track Ultra is a nice one, but it should be enough for you; two inputs, four outputs, and MIDI I/O is the basics of what you'd need. If you need more than one or two inputs then you can go with the Ultra (though running your devices through a mixer, if you already have one or can find one, can work just fine). I'm not sure about the DSP feature on the Ultra, but it might be something someone else can enlighten you (and me) on.
