Hi all,
Start a new thread here, thinking this message deserves it. It seems I find the quite easy solution this late evening.
Removed two Librarys in Kontakt Player - The Trumpet and Ethno World 4. Both were registered under Programm (86x) = 32 bit. But both were updated and so I was thinking with the new nkx.files they are in 64 bit now. (My sample folder and nkx-files are on a seperate HD.)
It seems, it is not the case. After removing the libs everything in MIR with Kontakt works like a charme. Changed all and everything, projekts, output formats, venues - every save fast and stable.
So it seems the crashs belongs the past. But I will it confirm tomorrow again.
Hope that helps for others too.
Kind regards
Frank
