Anybody expand their interface via ADAT? What are your I/O ping values?

Are you expanding your interface via ADAT? Which brand(s) do you use? How do you clock it? What are your ping values when using the I/O Plugin in Logic? Do they stay consistent?

 

I'm trying to troubleshoot a problem dcescribed on another thread ( viewtopic.php?f=1&t=133876&p=683799#p683799 ) and I'm looking for real world data and experiences.

 

My results:

 

RME interface, ping value always reported at 0 samples.

Focusrite Clarett Octopre connected via ADAT, ping varies from 4 to 36 samples, depending if it's a full round trip or not. AND the value varies randomly in the same project and I/O path

 

Thanks for any insights!

hi. I use ADAT light pipe output from my Mac Pro to my Motu 2408s. I have 2 MOTU units that each have 24 inputs and outputs.

 

so I basically run 48 in/outs to my analog console, when mixing, but usually just 24 inputs when tracking.

 

the 2 Motus are plugged into 2 Alesis HD24s for the analogue/digital conversion.

 

rock solid forever in my studio.

 

hope that helps Buddha

i have the Presonus Digimax 8, but never tested it. will try. do you use your RME as the master clock via BNC, or the external pre?

Thanks! I've done both: RME as master via BNC, and Focusrite as master via ADAT. The ping results differ with each method, but the problem remains: the values change for no reason.

wierd, i can't see how that would be possible without reseting audio driver

I've isolated the problem to the ping values for the DA conversion changing randomly. The DA is rock solid. Even a restart of the unit will make the ping values change.
