I also can see the bezier one being very powerful (yet could we be its master?)
This is a very interesting point. Blowfly in its current form is an example of an 'autonomous instrument' - where one doesn't 'interact' with it in the strict sense of the term. One can 'guide' it by setting rules and boundary conditions as it plays but within that framework, it still 'kind of does its own thing'.
An area of particular interest to me (not least because it has been explored so little) is that of semi-autonomous instruments. An example of this is Chaosorus - which I focus on
in this video I just uploaded.
The phase of a sine oscillator is perturbed by two small functions and depending on the parameter values of these functions, a variety of sounds are produced ranging from rhythmic noise to glitch effects to pitch gliding tones and chip-tune like melodies. What makes it semi-autonomous is that although you don't initially know what you'll get across the keyboard for the various parameter values, the same settings will produce the same results, so you can actually compose something with what it produces, and this is what I've tried to show in the video.
In other words at its heart is a process which at a lower level generates self-organized sound, yet at a higher level lets you play and arrange the sound sequences in the traditional composition sense. I think an enabler for creativity is to let go of at least some conscious control one has over the creative process...but not too much

, I thought I'd take the 'opportunity' to make another edu-demo video (something I quite enjoy but don't normally get enough time to do).
