I agree with Bud. I don't see the need for a light version and especially not a whole bunch of lite versions with different accessories. A person can go as deep as they want with BIAB whether it's covers or writing songs or learning to play. Even in a lite version they're still going to have to type chords in. And for covers - between tabs, song books, sheet music, midi files and .sgu files readily available - it's really not that hard to get started.

I played rhythm guitar and piano by ear and hadn't played in years when I got BIAB. I also had really limited experience with computers so if I could do it - anybody can. I haven't scratched the surface of all that BIAB can do. And I really like knowing if I want to take the time to learn more BIAB is right there waiting to assist. That's probably why it's used by so many teachers.

Also, I recall several years back there was a joint product between BIAB and I don't remember who now but anyway it was shipped with some other products like pedals or something and I think could also be had on it's own - seems like it was with windows somehow.... It came with a very limited number of backing tracks. Don't remember now what it was called but lite would describe it.
