Generally very happy. I'm in the middle of a record so no time to experiment but I have noticed a couple of possile problems: 1: When in cycle mode, Logic doesn't play the first loop of a selected track the first time around. Also it seems to spurt out a lot of midi data on the down beat (nb virtual instruments only...I don't use much midi stuff anymore). 2: About every 2 minutes when playing or recording virtual stuff from a controller KB my Unitor 8 goes AWOL. Panic button does nothing but when I turn it on or off it reappears until the next time. Very annoying problem which only appeared after installing 5.1. Anyone else got this one?
