Latency issues w/ Rosetta 800 and AD-16X

[kosmokrator]

Hi there,

i have a very strange problem here. System is PT HD3 on Quad-MacPro running PT 7.3
Converters are 1x AD-16X, 1x DA-16X, 1x Rosetta 800. All clocked via 192IO (i know, but it's not possible clocking via the XHD-Cards). All goes out to a AWS900.

Now, if I route a identical snare-signal both to the Rosetta and the DA16X, I have flaming going on. Obviously the latencies are way different. With timadjuster I found the difference to be around 600 samples!!
Now, whats the issue here? Also strange, the difference is influenced by HW buffer size. I don't get this. Doesn't the HW buffersize correspondent to all interfaces?
Maybe interesting: The Rosetta 800 is connected to a different Card than the DA-16X.

Any ideas anyone?

Thanks..

OK, Problem solved. L3 on mono-master in some strange way f**ed up the ADC...
