That’s odd! Can you post it to the support thread in my signature so we’re not limited to to 48 hour rule?
If you can post a screen shot of the audio options & what soundcard, OS etc that might be handy. This is just the JUCE standard output options in the Standalone App wrapper, I don’t really have any control over that as far as I know (but I’ve never looked into it). I set the project up as a standalone VST because that way it’s threaded nicely out of the box, but if it comes to it I could make it a desktop App like Kit Creator & implement my own threads. So far I prefer this option as it offers more potential future options.
