There is a lot that could be changed in a 1, 5, and 10-year plans. Here are a few ideas off of the top of my head:
1-a complete rewrite that includes all time signatures, streamlined menus, and a modern interface/GUI.
2-If no rewrite is in the future then streamline menus, like how many copy and paste options do we really need?
3-Become more like other software. By that I mean things like the horizontal bar in notation, the one like all other software has, except BiaB's doesn't work. You have to click on the little arrows.
3-Have the VST include all of the options in the standalone version of BiaB and when one does MIDI it doesn't clog up your HD with an audio version. This would combine both the Mac and Win versions of BiaB.
4-If #3 is implemented then do the same with RB, thus eliminate BiaB stand-alone completely.
5-Have multiple versions of BiaB, one for MIDI including all charts and MST, one for RTs and RDs, and one for both.
6-Have chord progression templates like rock, blues, jazz, new age, etc. The templates would be various chord progressions in each genre, i.e. 12 bar blues, 16 bar blues. Choose a template and the chords in the key of C would be implemented in BiaB where you would choose a key signature and style. This might help new musicians or musicians with limited chord progression knowledge.
7-Modernize all graphics and change the name to something like The Musicians Ultimate Accompaniment Software.


I get most of my exercise these days from shaking my head in disbelief.
