here is a simple example of chuck code for the Quasicrystal phase function QCphF
the Quasicrystal Phasefunction f(z) -1 to 1 and -i to i,
10-fold rotational symmetry,
red is minimum (-10), blue 0 and green is maximum (10)

Sporbits are based on bits of mathematics by NJ Wildberger, especially orbits of his Spread Polynomials

update november 2013 - Steel sheet and voice :YellowLeaves.mp3
april 2013 - Brass sheet and Electronics : Magicicada.mp3
DFF on his rather new brass sheet, the interactive synthesizer units are build in Max, using fractal samples and a spectral 13 tone harmonic system.
The harmonic movement in these compositions is generated by traversing twigs and branches of
the Stern-Brocot-tree via matrix multiplication.
((this matrix multiplication also allowed some paths between fractions which actually do not directly belong to the Stern-Brocot-tree :: multiplying by the "wrong" inverse matrices allowed some circular movements and sort of labyrinths))
The over all form is somewhat fugue like, though microtonal indeed. .. I did an mp3 compression of 320kbs to give space for the subtle dissonances.
play-back advice: low volume and quality amplification:
PrimeCircle - quadratic residue
PrimePop - cubic residue
PrimeOrder - quadratic residue
based on samples generated from the mandelbrot-set algorithm - orbiting points close to the boundary + some spectral arithmetic.(2012)
