Hello, I have been using Logic Audio for a while. now I'm on 6.4.1. I still have timing problems sometimes when using VST instruments. Even if I don't use alot of them. I use a Mac G4 Dual 1,44 Ghz with an MOTU 828 interface and Unitor 8 midi-interface. Anybody have any idea what the cause could be ? Internal mac, MOTU, Unitor ? Thanks for your replies.
