When I drag and drop from the DAW plugin to a folder in windows explorer, all the instruments with exception to the drums export ok, but the drums have an extra "thump" at the beginning of the first lead-in count, and I have to use either Adobe Audition CS5.5 or Audacity to remove that first count along with the "thump" but to stop the other wavs from being out-of-sync, I also remove equal amounts from the beginning of each wav file, then I can use them in Cakewalk Sonar to record multiple midi tracks along with audio vocals (which BiaB can't do), then add some VST effects and when satisfied with the take, I export (mix down) the entire session to a wav file, which I then use Audacity to convert the wav to MP3.

How can I stop BiaB from creating that extra "thump" when drag and dropping the real-drums from DAW plugin to a folder?
