YADJ, thanks for your post.
my macbook pro (2G) seems have the same problem these days.
most of time, only one channel takes all the task with that red end, the other channel doesn't kick much. the message of "midi/audio sync problem" shows, with lots of pops and noises. unfornunately, this is 80% of time for me these days.
the other 20% of time, both channel work in a pretty balanced manner, i don't get any error message and can use as many plug-ins as i want.
the two states can shift from one to another without any warning. but most of time i'm in trouble.
is it a problem for all logic users? i only have it recently. is there any way to fix it?
by the way, the second chip in my mac is a third party one, from "crucial", not a paired. will that be a possible effect too? i doubt it, since it was working very fine in the past and the problem has just come recently.
will appreciate any suggestions!
have a good weekend!!
