Thanks for the congratulations, Darryl!

It should be possible to record only 1 mono audio track, latency-free, without taking detours with Pro Tools (industry standard), Eleven Rack and a 3000 Dollar computer!
It is only for a single vocal track.

Of course I do not need 80 audio tracks. It was just a comparison to find out where the problem lies.

AVID itself assured me, that this must be possible and has therefore opened a ticket.

I can only work with 256 samples Buffer Size. For that I would not have had to buy a Mac Pro 2013.

You can hear it in headphones.

If I select "Listening with low latency", I have no headphone and effect send anymore.

So for me it is very probably a mistake! Other interfaces can do so, too.
