2012 Mac Mini, 32 and 64 buffers, HDN Latency

[propower]

Good point about the USB drive (though I thought that was more about USB2 and USB3 would not be a problem)...

I transferred the session to an external FW800 case - with Intel SSD. Exactly the same result. Good point though!

Doh!

Yes, that's what I thought too when I tried USB3.

I was getting crashes as well as poor performance to do with cmd S'ing at the same time as PT auto saving.

I haven't had the same problems since switching to the external firewire drive, which is a Glyph drive and performance improved.

Best,

John

Reading this thread with interest - getting buffer underrun errors a lot. Just had to redo 10 minutes of recording..

Mac Mini 2.7 Ghz i7 8GB RAM OSX 10.7.4. SSD System Drive recording to FW800 external drive ProTools 10.3.5 on a Digi 002 Console.

Also getting a lot of "Lost Communication" errors with the Digi002.

Front end is a ULN2. I have yet to try, but may try bypassing the 002, using the ULN2 as the playback engine, as the 002 may be the source of the errors.

Can't speak to the 002 but never any buffer underun errors with ULN8.

Have you tried just using the Mac built in input and output to see if you have the same issues?

[propower]

Yes I tried it using built in. The system delay alone is over 300 samples. Anything less than 128 buffer (though that might have been 256) had loads of distortion. I did this before installing Metric Halo.
