After painfully lurking in this thread for 9 hours at work I finally was able to come home and give this firmware a shot.
OSX 10.5.8 Lepoard
Ableton Live 8.1.1
Install worked fine, I didn't even bother uninstalling 3.0.3 before installing this one. Update took a while, everything ran fine, and it auto-rebooted me afterwards.
For a sanity check I was able to load up previous songs and even recovered one that I was having problems with earlier this month.
New patches sound great and I've been messing with them all night. I have to admit with the new arp and comb filter, my Virus feels very unfair once again. I was actually enjoying myself tonight working with outrageous sounds I actually wrote a song tonight.
Thanks Access!
