Thanks guys...no it's not anything to do with freezing. Next time it happens I will note the RT and post. I only really use BIAB for bed tracks for Sonar processing. And then only drums and guitars mostly. One thing is it SEEMS to be mostly happening with acoustic guitar parts, finger pick and strum.

Not sure how it can be a "selecting the wrong chord" issue?? I mean the chord progression is the chord progression, yes?
