Glad to be helpful!
And yes, I will reduce the minimum required version to 12.0 in a future release.
As a cautious upgrader myself (I lost some data back when Catalina stopped supporting 32-bit apps, not to mention the unwanted privacy intrusions that are plaguing each new piece of software these days), I prefer to keep it classic, so to say. But my initial choice of GUI framework was SwiftUI that is still half-baked at this point, and requires 13.0 for some of its features. I just checked again and 12.0 shouldn’t be a big rewrite. But Digitakt and Syntakt come first.
