Happens with Orchestral Tools libraries like Metropolis ARKs and Inspire 1 and 2
using Cubase 10.5 and 12. Happens in both versions of Cubase.
doesn’t happen in Kontakt standalone.
when load any instrument from any of those libraries, a red exclamation symbol with cpu overload spears in Kontakt.
and when the error goes away, all of a sudden the sound starts playing if the notes that I was playing while it was loading. Seems like the notes were memorized in the buffer.
