Thanks, I’ve received files from Ulrik and David.
Unfortunately - as I already assumed - from the log files I can not see anything suspicious.
Only thing that I wonder, you both have Pianoteq 5 and Pianoteq 6 installed. Apparently P5 comes only as VST2 and P6 as VST3 plug-in. Why do you still have P5 whitelisted in Dorico? Does P5 do something better that P6 can not do? But that just as a side question.
And David says that P6 does not get listed in Cubase Pro. Does P5 get listed and can be chosen?
How about in general with the noise? Does it only start when you select P6 and stop immediately when throwing it out again?
What is with P5? Same thing?
