Dunno if the EZ 200 has it's own MIDI driver or not (which would determine if it shows up in driver list or not). It may require a USB-MIDI adapter in which case it would show up as that driver.. it would likely show up in an area near the Forte DXi (since t is software and the Yamaha is hardware) but should be intuitive enough to figure out.

Yes; each track in RB can have its own synth .. up to 16 software synths and however many hardware synths you can figure out how to route with available putput ports. MIDI OUT port restriction has never been an insurmountable issue here, so basicly each track can have its own synth for all practical purposes.

If you want multiple hardware synths you may need multiple physical ports or learn how to be creative with the existing ports, but RB is up to task in this regard as long as hardware allows it.

RB simply sends the MIDI out to any available MIDI port (per track), be it software or hardware.

I do not work here, but the benefits are still awesome
