Actually, BIAB went from 16-bit to 32-bit with BIAB 2004. This from the 2004 upgrade manual:

Quote:
All New 32-bit Program Engine

Previous versions of Band-in-a-Box were a combination of 16-bit and 32-bit
code. The new program is rebuilt with a 32-bit-clean engine. Program
operations are much faster, including up to 3 times faster notation redraws, song
and soloing generation. Playback timing is improved and rock-solid with all
versions of windows, including the newest XP and Media Center operating
systems. The GUI is enhanced with floating/dockable toolbars.
