Have you checked your buffer settings? May be worth upping them from whatever they're on atm. You can find them in Logic-Preferences-audio. I'm on Mavericks and don't have this problem.
Im gonna have to try this on a new project if i wanna do tests, i up'd it and one of my massive channels got set back to default, but only one so im completely un clued as why any of this is happening, but thanks for info, ill try this in a bit
If plug in delay compensation is off, turn it on.
Also, try the following:
Menu > Preferences > Automation
Adjust the snap offset and ramp time. I think te ramp time defaults at 200 ms, which is quite a lot, so change it to 30ms or whatever.
I changed it to 30, then 0, now i think it has made a difference but only subtle, thanks man. as russ said, most likely down to the big projects, the current operating system is leaps behind in performance theres so many bugs.
Im gonna ask this here instead of making a new thread, 'when i preview mp3's, wavs and all audio with the space bar, there is a significant delay till the audio plays, now my laptop running an older osx does this very quick and smooth, my new comp running capitan, has heaps more power. Again, is this something that capitan is known for? If I were to downgrade to the right osx, would it change this?
Cheers for the input and time guys, much appreciated
