Thanks for all the responses.
I have plenty of MIDI cables so I don't mind
having to plug them in. It's also better
in the long run to have separate cables,
because what do you do if the one piece
interface's midi cables start having problems?
I guess my only reservation with this Evolution unit is the drivers.
Roland is the defacto standard for MIDI
interfaces, so maybe spending a few extra
dollars will be worth it.
