I have version 3.3.4 and wondered if that is the lateset version or if there was a newer one?

Also, do you think there would at any time be a scaleable option in the future?

Thanks in advance

Yes, Microtonic 3.3.4 is the latest version.

The interface is already scalable: open Microtonic’s main menu in the top-left corner and choose Zoom.
