So, some people don’t know what smooth-scrolling is. Smooth scrolling is having the content of an application windows scroll with the mouse-wheel in a way that is gradual and consistent, rather than a series of chunky jumps between the content. There is no frame-rate requirement for it, as it is not locked to a frame-rate. Cubase itself doesn’t have a frame-rate, but will display according to whatever your personal monitor supports.
And I don’t know what the point showing that browser plugin is supposed to be making, because I don’t have that Logitech extension installed in Chrome, and yet Chrome has smooth-scrolling. I don’t have an extension in Firefox, and yet Firefox has smooth-scrolling. I don’t have an extension in Opera, and yet Opera has smooth-scrolling. I don’t have an extension in Edge, and yet Edge has smooth-scrolling. Even Internet Explorer has smooth-scrolling.
And +1 to adding smooth-scrolling to Cubase. It’s long overdue.
