Absolutely correct Robin, not latency free, just sensory and audibly 
indistinguisable from latency free (that is why I included  "it seems" 
with latency free in my statement..
I could have used better grammar.

I get 2-10 xruns in the brackets, when I just start up, probably while 
starting jack etc.
After Mixbus is started and up, it stays at that value for hours as far 
as I tested which is supernice.

There are no more clicks every minute or so. All gone.

I just wish I could work at 48000Hz. 1818VSL refuses to do it even 
though it can do 96000. It is a stupid process of using windows 
configurator software to set it to 48khz, but after I plug it into linux 
all I get is 44100. Maybe I dont understand alsa correctly, because a 
48kHZ jackd string doesnt work at 48kHz.

That will enable me to increase the buffer for the same latency and is 
the quality I want to work at.
