Having Lag issues in Logic 9 with Access Virus TI

[arzie]

Hello,

I've been working on a song using my Access Virus TI Desktop Synth in logic pro 9 via USB with the ControlPlugin and using all 16 available tracks from the Virus and it seems like every time i double up and let two synths play the same thing, often times everything throughout just starts getting laggy and falls behind, and sounds like i'm not quantized and I am! Or simply if i just have too many parts playing at the same time, it's quite frustrating.. Does anyone know what causes this and how to fix it?

Below, I attached images of the settings I'm using in logic, as well as what my project looks like if that helps by any chance, and the settings of the mac I'm running on..

EDIT: I realized how small those photos are so i've uploaded them to imageshack-

Thank you very much for any help!

Apart from the things said over at the access forum, you might as well want to leave 1 bar empty before the song starts (Or move all regions 1 bar to the right). Good luck!

it just gives the external and internal devices time to synchronize.
I use the virus Ti2 in oldschool-mode, by the way
(Ti2 stereo out -> Audio interface in
Ti2 midi out/in -> midi interface out/in) + DAW multitracking. My Logic 9 doesn't seem to be too happy about 2 audio interfaces (Focusrite + Virus TI2), so I don't use multis. Happily, I don't need to
