If a midi patch sounded as good as a Real Track, there wouldn't be a need for RT's, IMO. My old Tyros keyboard used patches called "Mega Voices," which had to convert regular patches to them. They were the Cat's Meow and sounded as good as a RT. You couldn't record with them though, they worked after conversion.

The Biab Midi Styles are fantastic. If you have a hardware synth to use with them, Biab sounds like a whole different program compared to the standard Forte/VSC. I actually prefer the Biab Midi Styles over the RT ones, but since I don't have my Tyros anymore, I prefer the RT's now because of the sound.

There is a night and day difference when using a synth that sounds and emulates a real instrument, compared to the standard GM palette. Plus, midi data allows much more control when creating a song with a Biab Style.
