Some weeks later…
I joined the NI world with Komplete 14 some time ago. This includes Kontakt 7 which is running - well not so OK. I have some quiet glitches when I load a library (e.g. Alicias Keys) when playing within the first 5 seconds. Even if the rackspace is loaded for 20-30s, as soon as I start to play there are glitches, then everything is OK for ‘hours’
Also some libraries like Session horns showed up with delayed first notes like a 30ms latency when playing first time, then also after 2-3 more notes everything OK.
I’m on macOS, M1 Pro. Latest Kontakt 7.10.7.
Anybody experiencing the same? What about the current Kontakt 8.2.0.?
I don’t think that I will upgrade to Komplete 15, but I could imagine updating to Kontakt 8 if these problems would disappear
I know there have been some discussions about Kontakt 7 here in the past, and some of you are still on 6 - where I don’t have access to 
Any other ideas how to get Kontalt reliably usable for live? Any tweks/settings I could check (besides switching off sharing usage data generally)?
