Well I ran my MT at Disco Biscuits the other night at Starr Hill, first set went great. I was doing 16/44.1. The rig was a SP-C4 > mme > mt. First set was about 1 hour 6 minutes, no problem. Second set ran over 1 1/2 hours and the MT cut out. I only got 1/2 the encore bah! Oh well, my mme was still in high gain (who the hell sets those jumpers at the factory for a field unit to high gain...) which was promptly fixed after the show.
Things I have noticed when I have problems:
Usually its after I started another file, so I try to do one file per CF card and only after a format.
Usually cuts off when I forget to set the hold button immediately.
I am running at Robert Randolph, Drive By Truckers and Man Mountain Jr. tonight. Here's to hoping for the best.
