Thanks Noel. I appreciate the reply.

For reference and with respect to your intent, I have a long history and much experience in music production. This is not something as extreme as 48khz vs. 44.1khz . Some instruments (not all) are literally .01% out of tune and it is discouraging, as if they were recorded slightly out (imagine a guitar note slightly sharp on the tuner, enough so you desire to flatten it) . Also, my sound card is a high-end interface that is accurate with a very stable digital clock.

These tracks are in tune at 44.144 khz. I suspect perhaps the speed/slow function of BIAB has slightly changed the tuning? Sounds that way. Doesn't happen in Nuendo or Cubase. Perhaps I should have bought the Audiofile edition to get the original tracks untouched? We see what I can do. Thanks again.
