Could you try the new v1.1.0 download? I believe I have fixed the issue that prevented extracting the .zip file properly on macOS Ventura.
hey, I downloaded it, unfortunately it is still not working and I still get the "cannot be downloaded because the developer has not been verified" however I was able to get the standalone app to work so I finally got to try the synth and it sounds really nice! I was able to download the plugin version but as soon as I actually copy the file the message pops up. I guess Apple has some kind of verification process now
According to this article from Apple, https://support.apple.com/en-gb/guide/mac-help/mh40616/mac, there should be an option to grant an exception to allow the app to open in Privacy & Security settings.
