Last time I played with Band in a Box wsa 1999.. didn't realise it was still going..

Back then it was handy to use it to turn a computer into the kind of quick compositional & backing tracks arrangement tool
as found in home keyboards and more pro workstation keyboards...

[ think of the cheap yamaha keyboards as used on stage by Frank Sidebottom..]

Better investigate how much more advanced latest version of B in a B is...................................


5 Minutes Later:

Definitely far more advanced in 2017...
