After I drag and drop a series of grooves into a track in pt. there is always an issue with consistent playback functionality. Like it looses the beat for a second. I have isolated where this happens a number of times, and play the track back from a spot just before the problem, and it will be perfect, but intermittently. Any ideas?? I am running win 8.1
