When transcribing a source, the feature now analyzes all tracks within the file. Not a big problem if all you're doing is an individual stereo track/file.
However, for when we have a single .wav file with numerous tracks (1-mix, 2-lav, 3-lav2, 4lav3, 5-boom) Transcribe will go though all tracks, which is redundant and and a horrible waste of time.
Obviously, choosing ONLY the mix for transcribe would be more than adequate. Having that option would save hours of wasted time.
