Really cool! Please consider replacing the tiny knobs with something a bit more user-friendly like sliders
Yes, please. I like the concept, but found using the dials really fiddly and unintuitive. They don't seem to "turn" like one would expect, working only off the height of the mouse cursor after starting interaction.
It was actually intuitive to me.
But I'm used to interfaces for VSTs (audio generation/effects plugins) that usually have this exact interaction mode. See http://www.protoolerblog.com/wp-content/uploads/screenshot_O... for an example of one.
(Sometimes VST knobs also have the extra of horizontal movement being a "fine-tune" mode, even, which is very handy.)
