Hi Graham
I consider myself to be an 'average' user, not into many of the clever tricks that BB can do.
I'm a Soloist guitarist and use BB to make backing tracks that would be otherwise unavailable or to arrange a tune in a personal arrangement.
Click on the SoundCloud link to give yourself an idea of what it can do.
BTW - I have Ultra pack so have the max possible RTs and RDs. I seldom work with midi as, for me, its too darned complicated and I'm an old fashioned Analogue sort of guy at heart. lol.
HTH
