Band in a Box have plenty of save options like ones in "Assign Instruments and Harmonies to Song", there is for example "Save Mixer settings w/each song (Vol,Rev,Pan,Ch)". Whereas the wonderful and amazing advances and improvements in the program in terms of programation we has been witness, it is very probable BIAB design team can assume without problem to add an export or additional save mode similar to SEQ file format which would retain our favorite last regenerated take, it could be loaded back in BIAB and even exported to Real Band. There would be sub-options like "select MIDI/RT instruments will not get regenerated on load" in the case you only want determined instruments to remain intact at reload.
Reason I think this way? sometimes and not un-frequently I want stay ONLY in Band in a Box without switching to RB or any other of my DAW, maybe because I don't still need it, maybe because do it could interrupt my creative flow in a strictly musical level. If I want to capture that wonderful regenerated backing track take which match perfectly with that spontaneous solo or melody created in my BIAB song or piece, then being not able to make it would be inconvenient or even annoying. That kind of improves and additions, which expand the freedom of creativity, will look great and worthy in any program new number version ...like Band in a Box 2010
