Looks exciting - but, TBH, I wouldn’t want to spend hours editing with this theme - would probably make me too aggressive. Plus, it’s not really ergonomic (contrasts, hard-to-read rack/plugin labels.
Increasingly, I tend to use very simple, relaxed interfaces that help me concentrate on content/workflow and not on shiny reflections on buttons etc. And when playing live, that principle holds even more: I need layouts / colors that let me focus at one glance on what is important.
Live interfaces tend to be more colorful for me than Studio stuff: I spend more time staring at the screen in the studio, so I need the screen to be more subdued to not wear my eyeys out - couldn’t work with this theme at all. When playing live, colors are more important, since they help “anchor” the eye quickly when simply glancing at a screen in passing, so I use bright colors and strong contrast to set important items off from the un-important - doesn’t look very sophisticated like some of the fancy tone-in-tone DAW interfaces but helps navigate quickly on stage. But too much color would be like screams from every direction of the room: you don’t know where to focus.
So whilst this theme does really look cool when showing off Cantabile, I don’t think it really helps USING Cantabile.
I think that @brad has done a great job combining looks and ergonomics in his two themes.
Just my 0.02 EUR - no offense…
Cheers,
