Well, that's the first time i had to downgrade due to bugs/ instability .
At first, I noticed a noticeable delay (lag) when switching from Tuner to Browse, or from Browse to Performance mode. After playing some time on Performance I wanted to take pause from playing , switched to to tuner but nothing happened, just froze. I turned it off, rebooted , tried to switch back to Performance mode , but this time immediately after switching to browser it started to squeak (loud high pitch sound through my cabinet), and it was frozen again. Rebooted again and after that played without issues...
....until the next day, after playing for about 30 min i got "blue screen of death" (so to speak). It happened while trying to copy and paste fx from one stomp to another stomp slot.
IMHO FW 3.0 shouldn't have "release" status.
Just wanted to share my latest bad experiences after upgrading to FW 3.0.,
