For the Harmonic Algorithm, H-OUT, each of the three voices is a 24-partial harmonic oscillator, using
high-resolution sine wave generators. The timbre is varied by the CENTROID and FLUX parameters, with CENTROID
setting the loudest of the 24 harmonics, and FLUX setting the steepness of the gain roll-off around that center
harmonic. When FLUX is full CCW (0% modulation) the spectrum is flat and sweeping the CENTROID will ripple the
spectrum (like a string harmonic). When FLUX is increased, the harmonics sur
