It's simply plug and play. GM and GS compatable. Mac interface on back of unit. Not much on pianos, but some good organs and EPs. Choirs and Brass sounds really really stink.
Strings are good.
It has some good synth sounds too. A good starting unit for a begginer. 10 Very reliable. I've never had a problem with it. It was my first module and I have since moved on to bigger and better things.
