How are the orbit points transformed to the microtonal scale?

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.
