regarding the learning curve:

one thing that's different about BIAB is that you don't have to know everything in order to make it work. Now, the more you know (and that comes with time and practice) the more musical problems you can overcome with the software... but... unlike almost every other piece of music software, with BIAB it *IS* possible to load it and start making really good sounding songs almost immediately.

Start by opening it and playing the demo songs. Once you buy it, let us know and we'll coach you throughthe process of playing the demos.

THAT alone will take a long time, as there are lots of demos! By the time you get finished playing them, you'll have aa baseline comfort level to start typing your own chords.
