I have owned BB for many years and have learned quite a lot. As I wish I could play an instrument but that is not one of the things i have been able to accomplish. but....
BB has allowed me to put into musical expression what goes on in my head,,, to a point.

The dilemma as I see it is my lack of musical ability, is RT"s stop short of us being able to be the brains and talent behind the musician, hence the compositions fall a bit short of (in my case) my expectations but is far better than than without it.
Now those who play, I can see the frustration of the rt styles being stale. they are for me also, but stale is better than none and for the price, well worth it.
I recently watched a youtube vid by Guy Michelmore, a British composer using Cubase Pro and Native instruments and other hardware with his keyboard. There was the gap between me a wantabee and where my head hears ideas.
BB can be more but at what price?
Just an observation not a solution
