Hi folks,
I was trying to run the fireface 800 along with the presonus firestudio,
the main problem is that the firestudio does not have any kind of clock port or stuff like that, considering
that I'm on Snow Leopard with Logic pro 9 I've created an aggregate device that merge the two devices into a virtual one.
All seemed ok in the first place, Logic recognized the aggregate device and the inputs.

But after a few recording tests I discovered a couple of problems:
1. the audio recorded from the presonus channels in not in sync with the rest of the tracks that comes from the ff800
2. all the tracks form the firestudio have a sort of craking in the audio.
 
anybody ever tried this kind of configuration?
or do you have any kind of suggestions?

thanks in advance.

K
