Hi guys, i leave here a mail from access staff:
"Dear Fabrizio,
This is in reference with your Request Ticket Number: SI00013114.
Dear Fabrizio,
What is the audio buffer size set in Logics audio preferences window and what is the "process buffer range" parameter set to in the same preferences window?
Also what other USB devices are connected to your Mac besides the TI and what is the delay compensation setting set to in the Logic preferences?
Best wishes,
Jörg Hüttner"
and this is my answear:
Dear Jorg,
The audio buffer size set in logic is 128 Samples.
The process buffer range is set into "LARGE"
The plug in latency compensation is setting to "ALL"
The others usb devices are the apple keyboard and a logitech mouse, but i don't think that is influence on it.
I have to tell you that from when i have installed the new system 4.0.0 the sync is better, is not perfect but the problems of sync are less.
Hope to receive an answear of you soon.
best wishes
Fabrizio
