I think the idea of having twelve key "woodsheeding" Real Tracks is a great idea. However, why not expand it to other instruments such as bass, saxophone, piano, trumpet, flute, harmonica etc? Also, why not make a "woodshedding" version of drum players who use Band-in-a-Box to practice along with?

I guess I don't understand this request, so could you clarity please?

BIAB can already cycle through all keys for all RealTracks, to my knowledge, in the Window, Practice Window, Transpose Songs menu. I'm not aware of any utility RealTracks for this, unless I missed something. However, I do not know if this is in the Mac version of BIAB.

And what would a woodshedding version of drummers be? Changing to a different drummer each chorus?
