By the time you truly master your VA76, all that software will be out of date!
Concentrate on one thing. You can't learn the piano while you are blowing a trumpet and banging a drum. Give yourself (and us) a break and settle down and CONCENTRATE ON ONE THING for a while!
It would be SO nice if we could just answer your questions (or try to) about the VA76 - especially as this is an ARRANGER forum. Propellorheads have their own forum, as does Cubase, why ask us?
This forum is probably mostly attended by musicians in their more mature years (OK, we're old guys!), with many, many more years experience playing and using technology than you have. Why not just accept what we say?
If not, there's always Ritalin (just kidding...........!)
