Hi Byron:

Your question doesn't really address the technical issue. Being an engineer, I'm looking at the tech as to why the glitch.
Your answer however is that I'm on the road between Bangkok, Amsterdam and Mexico City - and this is a porta-rig that goes in my carry on. As quick rig demos or backing tracks with a USB mic, quickies and sketchbook production should be doable to catch and lock the takes without something like the Focusrite or my main full studio rig or my main mics.
As mentioned in the post, the takes went fine to the utility tracks and played back fine as well when done on the first production.
