The plugin also uses a helper file which appears to be another variation of the main file.

That makes sense because BiaB's track generation only takes a few seconds while RB's takes minutes. But the reverse is true when saving BiaB's tracks as a .WAV file versus saving RB's tracks as a .WAV file. In other words, the helper file for RB must be doing more than just generating BiaB tracks or it wouldn't take so long.
