Main thing is, it's a generic MIDI controller, made by Yamaha for several different things. If Yamaha's preset pedal assignments aren't to your taste, you may have quite a job reassigning them.
BTW, Donny doesn't even use a SUSTAIN pedal, for Pete's sake! Advice on this subject from him is like asking a blind man to pick a color for your music room...
