If you render the song to a WAV file, and then make any change to the BiaB song and then play it, the original WAV file you created will play along with the new/changed song.
Could this be what is happening?
Nope... I ALWAYS save the BiaB file and the WAV file in separate folders...
But ok, I just ask someone to load that song, primarily PGMUSIC staff, since that is part of their job, as customer service.., if I am not wrong about that, do the same and see IF I am the one that have something in my SETTING, or, something in my system, or, something I do, that makes this happen, AND what I can do to avoid it for the future... That's all...
But ok, IF I am the ONLY one encounter this problem from time to time, then IT MIGHT very well be something I do wrong, OR, something wrong in my computer...;) Because, as I mentioned, it happens not only ONCE for me...but several times... My solution, WHEN it happens, is to RECORD it directly to Audacity, from Biab...THEN, the problem is avoided...;) THAT just being a workaround...
