DIN IS NOISE
This is the most incredible piece of music software that I have eever seen. It's frighteningly close to some of the ideas I've been (unsucssfully) trying to implement for the last decade or so. The most telling similarity is is how it's very careful about keepign thins specificed in the abstract, even after processing them with layer after layer of user manipulation.
You see that trait most easily when he moves into the (Bézier-spline based!) waveform editor and suddenly jump back to editing the foundating of the sound that's been constantly manipulated the entire time.
I was approaching it more from the style of how the DS-10's interface works - more of a traditional loop based, scale frame work. If find it really interesting, though, that he's very successfully setled on a microtonal apprach, where I was going to to in totally the opposite direction with even more emphasis on harmony/melody. and hoping to get the recursively-self-generating properties by adding that dimentionn to the equation.
Here, though, his approach now seems obvious. It's simply taking advantage of the natural properties of his interface: the mouse/etc and their rather specific movement properties. It simply mapping the pixel grid of the screen directly to the microtonal "scale": perfectly intuitive.
While that first video was just plaing around/demo, the explanation given in other videos gives a much better jobs at explaining this amazing instrument:
