Hi all, it's been some 8-10 years since I posted on the LUG - I remember when it was on the yahoo groups... Anyway, my setup is: Logic pro 8.0.2, tr-rack, jv-1010, jp8000, amt8, genelec 1029s, MOTU 828 mkII. Yes, the stuff is ancient, but it all works great on OS 10.6.8, so while I would like to upgrade to Lion, I am concerned about any possible incompatibilities from logic or any of the gear with OS X Lion. First, is there any potential pitfalls between logic 8 and Lion, or any between the AMT8 and/or my MOTU interface and the new OS? Thanks to all who can help, and I'm glad to be back.
