The trouble is that there has been no update information since then, not even a minor update to fix bugs.
Last year, I sent a message to them that the Reverb installer would not start on MacOS X 11, they sent me a test version of Reverb (and the VST3 version!). but even that has not yet been made available as a download link from the user page.
I wonder if this company is dead?
Does anyone have any opinions or information on this?
