tELHARMONIC Harmonic Algorithm


Published on Aug 6, 2015 MAKEN0ISE

"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 surrounding the CENTROID decrease in
amplitude and the sound becomes more focused upon the center harmonic, which causes modulation of the
CENTROID to have a more dramatic effect.

When FLUX is not set to 0%, a trigger or gate in the H-LOCK input, or a press of the H-LOCK button, will cause the
partial that is currently selected by the CENTROID parameter to be locked ON at full amplitude even after
CENTROID changes. By sequencing CENTROID and Locking harmonics, many additive timbres can be found. Press
and hold the H-LOCK button for 1 second, or set Flux to 0% via panel control or CV, to clear all locked harmonics.
This parameter affects all three voices of the H-OUT, but does not affect the P or N OUTs."
