Thanks for posting that video showing the problem.  We were actually able to reproduce the problem using the latest PitchFactor bam.  So, it looks like you found a bug in the latest PitchFactor release.  We were planning on putting out a new PitchFactor release soon anyway to add the new routing modes, expression pedal to volume mappings and other features in the most recent H9 release.  Hopefully, we'll put in a fix for this problem as well in the next release.
