If you can put the wave instructions in the BBoutput.txt for the other tracks it can then be inserted instantly into Reaper giving total editing control rather than the consolidated wav.
This is the BBoutput.txt for the 7 Multiriffs it has the wav instructions and
I can read them directly into Reaper then just delete the wavs in the SavedTracks that bbw4 went to so much time and trouble to create unnecessarily.
To keep all these files "BBoutput.txt etc.." put an empty txt file in \bb\BBPlugin named "PreserveAllFiles.txt"
