Manual = g00d.
Yup it sure can do style changes within a song.
Turns out biab has extensive MIDI control implementation.
The FCB is perfect for it.
Looking at the Conductor window; it means that when the piano player yells "Bridge!" I can hit a button on the FCB and biab will go to the bridge....in time...after it finishes the current measure!
That's a small miracle right there.

Now to figure out what hardware to use....
In a live situation latency will be a big problem if I were to try to go VST. I could use my Triton but sheesh I setup everything now and the last thing I need is another keyboard. Is anyone using VST on a laptop w/o latency issues?
I need to open a new thread....
