But Peter,
It really doesn't change the fact that the print notation (that is the paper representation of the song) hasn't had any significant updates since 2004.

I agree that ther have been data input updates, but we still have fixed bar lengths, although we can assign the number of bars on a line. It's still very difficult to get note lyrics to line up when dealin with multi note bars. The last bar on a line can cause all sorts of problems due to lyrics wrapping to the line below.

I love BIAB; note, lyric and chord entry is a breeze, and the sound of the 'band', even with basic midi is amazing.

Perhaps BIAB is not a piece of notation software, and I should consider investing in a dedicated notation software, but I am not prepared to create duplicate copies all of my songs. BIAB notation could be a lot better, or at least provide a simple but comprehensive interface to another program. Wouldn't it be nice to use the same dialogue we use today to get a professional looking fake sheet?
