Music is actually microtonal but don't let that put you off.

How are the orbit points transformed to the microtonal scale?

Out of the five different audio files you have at the above web page, I liked "septimal" the most.    :D

Hi eiffie, my laptop is under-equipped for this music making so i made the sequencers simple. Each orbit co-ordinate outputs to a midi channel. A co-ordinate is assumed to be within -2 to 2, it is normalized to be between 0 and 1, multiplied by a pitch range parameter, rounded to an integer, transposed up or down by a transpose parameter, then clipped to be between 0 and 127.
Each midi channel is therefore a constant pulse of chromatic note numbers. I use the microtonal softsynth Zynaddsubfx to add rests and restrict to a scale by simply using it's excellent programmable keymapping, by editing this i can adjust note density and which notes in the scale have preference.
The same midi channels drive the drum machine, again rests are created by using a carefully designed 32 piece drumkit with gaps so many midi messages trigger nothing.

This is the basic 2D Mandelbrot sequencer that shows how the 4D and 8D ones operate:

Nahee, thanks, Septimal is actually a microtonal 6 string bass guitar improvisation using an Ebow and multi-looper.

Thanks for the explanation menokefug! This mapping sounds similar to what I am doing with Sloth Canons (another thread). After getting the integer values (from a different method like brownian motion) I toss out the chromatic notes that aren't in the selected scale. It gives a very natural rhythm that makes me think we do this subconsciously when we write music???? Now I have to learn more about microtonal scales. Thanks again.
