Count me in as a dedicated BIAB user. I started with the program when it was version 2-point something. Now, it's 11.0. As a guitarist, I find uses for it as well as arranger keyboards. One thing I really like about BIAB is the precision of the bass line. It will track the movement of 4 chords in a measure at a quick tempo, where my 6500 will often glitch or respond slowly on such. It all depends on the style of the song and how much time I have available as to which program I use to create tracks.
