Problem delayed tracks / Sync?


Recommended Posts

Hi there,


for a recording session I need 24 input-Tracks.


My configuration:

iMac 2,4 GHz / 4GB RAM

OSX 10.6.6

Logic 9.1.3

Focusrite LiquidMix32


MOTU 828 mkII

M-Audio Fast Track Ultra


I created a new audio-device called EPTotal in the audio-utility. The first device from EPTotal is the 828, the second one is the Fast Track Ultra. OSX makes the checkbox "Resample" = TRUE. In Logic I choose "EPTotal" in the audio-konfiguration.


8 Track from DI Mackie Desk to 828 Analog IN

8 Track from DI Mackie Desk to M-Audio Fast Track Ultra

8 Track from Yamaha 01V to 828 ADAT IN (optical) --> 828 is master / 01V is slave no wordclock/sync problem.


In Logic there are on all 24 Autio Tracks a signal. So far so good. On all channels of the Fast Track there are a larger latency. After recording, all tracks from the Fast Track are delayed about a half beat. But it various from take to take.


At first, I thought it was a sync-problem. So I deactivate the 8 ADAT channels. No result. I tried to set the "Resample" checkbox = FALSE in the audio-utility of OSX - no result.


Has anybody an idea, what the problem could be?


Lot of thanks.
