Ian, versions of BB that were made before the advent of the Elastique stretch engine use several Realtrack files for each melodic instrument Realtrack.

If you look in the folder you will see that there are files with the same name but slight changes at the end of the filename, such as +1, -1, etc.

Those are identical files except for the key they are played in, typically there will be transposed files there covering the diminished chord. The older stretch engine would pick the file closest to the key you designated and then would only have to stretch the pitch by an amount that would not create digital artifacts.

With the Elastique engine, stretching to any key from one soundfile is now possible, so there is no longer any need to have all those duplicates.


This decreases the disk space needed appreciably and more different sounding Realtracks can now be stored in much less space.
