--- Comment #2 from Emmet O'Neill emmetoneill.pdx@gmail.com --- I forgot to mention the context of the "laptop log" attachment.
While taking this log, I simply opened Amplitube, turned on the metronome click, and then hit the "play" button to start the playback timer. (This is a decent way to visualize the hitching without too many other things going on, i think.) I let the program run like this for a few seconds before hitting the close button, saying "No" on the save prompt dialog, and ending the process.
