If you have that problem with delayed problem, could you please create a simple piano project with just a dozen arbitrary notes, press Play, wait for let’s say 15 seconds and then choose from the main menu Help > Create Diagnostic Report. That will create a zip file on your desktop with all sorts of logging data. Please send it to ‘u dot stoermer at steinberg dot de’. I can’t promise that I will find something in there, but this is really the best way to get more insights.
As Paul said, this is most curious and we never heard about so far, so we want to know more about.
