Masscore and Ultra Low Latency

Postby Sylvain94 » Fri Feb 22, 2008 17:25

On my pyramix, when i select Ultra Low Latency, i have a lot of sync pb with my monitoring interface (clic).

My combination :
Masscore 48
X30 - AES SRC
Avocet in AES

AES 1-2 go to Avocet for monitoring.

I've also seen that the jitter is very high and have some "peak of jitter" during this clics.

I had same problem.

But I could solve this problem, increasing 'Playback buffer size' until no click noise.

try this.... :D

Hi Sylvain,

Please verify the DMA load (debug>DMA load) it might be a good thing to work in Extra Low latency in this case. It will depend of your workflow and if you use plug-ins or not.

Regards,
Ricardo

Hi Sylvain,

Glad to know that it is now working, note that we are still benchmarking different daughter-cards that could have difference performance values in Ultra Low Latency.

A small note on the Pyramix V6 latencies.
Note: Please be aware that some of our competitors only take in account latency from Live In to Record; in our case this would means 0.665ms in Ultra-Low, 1.33 in Extra-Low and 2.66 in Low Latency. But, since from Live In to Live Out is the ‘real-world’ figure, we calculate it as 1.33ms , 2.66ms , 5.33ms respectively.

Regards,
Ricardo
