Bug fixes.
• Random Loop Phasing: closing the N.O. on a loop that is IN phase no longer blows your cutouts. Out of phase still does — check your phasing before you close.
• Sound, Vibrate, Fault Indicator and Random Loop Phasing settings stick between sessions.
• Memory no longer piles up as you move between labs.
