Thanks Noel. I wasn’t aware of those settings. BIAB has more switches than an aeroplane cockpit! The problem came about because I had a RealTracks in a Utility track and it was adding embellishments so I switched the auto-fix sour notes. Then in a later session, I swapped the Real Track for another but had forgotten the track setting. I went down a rabbit hole of checking sampling rates, audio interface settings, RT verification etc - all to no avail. Then I remembered the auto-fix setting, and sure enough, that was it. Obviously, I learned in the process that auto-fix is a track setting, not attached to the Real Track. I’ll check out Natural Arrangements and if I strike any problems, I’ll take you up on your offer.
Thanks for your advice!
Andrew
