Dude - how did you say all of that without taking a breath? Can you do circular breathing like Kenny G?
On a serious note, I am running a MacBook Pro I7 and have never gotten the bit crusher sound, but every once in awhile the latency will go to 2-3 seconds or more. I will play a passage, take my guitar off, and put it on the stand, and I will then hear the passage I just played. The only way to fix it is to reboot LOGIC 9 and the Axe. I don't rely on recording or guitar to make my living, so when it happens about once every 4-5 times I sit for an evening to tinker with recording, I just save my work, and reboot. I am a little concerned to read that this doesn't have with Windows machines, as I took the plunge and switched to Mac about 18 months ago, which was about 6 months before i purchased my Axe II.
I just upgraded my Mac memory from 4 to 16 RAM, but I haven't tried to record anything since doing this. So, I don't know if the increase in RAM would appease and rectify this tendency to fail after 45mins to an hour like the guys have reported.
PS - no punctuation was harmed during this post.
