Since a while back, Klevgränd has been working with new ways to interact with virtual interfaces. One of the ideas ended up in a remake of their earlier release, Syndt. Instead of presenting a UI with knobs and sliders, the user gets a bunch of presets wrapped on a three dimensional sphere. By rotating the sphere (just click and drag), internals in the synth engine will be morphed and the sound will change. There’s also a few traditional parameters for global settings.
And it’s free for desktop!
