the only flaw I found so far is that I cannot export (importing works instead) the Scaler status from Cantabile
I believe this is an issue with the way the choose file selector is implemented for plugins using the Juce library. I’m working at the moment with the developer of another plugin that has the same issue, but this could be related to a specific combination of Cantabile/Juce. It might be that the fix is for the developers of Scaler to rebuild with the latest version of Juce, but until I have more information I can’t really say. I’ll post back when I know more.
Apart that, I found that Scaler works very well in my Cantabile Solo
