This diagram shows SPARK's feedback signal flow
The output of the Oscillators section is the mixed with the feedback signal by the crossfader
marked as "Filter FB" and fed as the carrier signal to an amplitude modulator, the first ele-
ment in the Ringmod/Filters section. Again, the modulating signal again is the feedback signal.
Amplitude modulation reduces the presence of the carrier signal harmonics, but adds the
harmonics of the modulation signal into the mix in a more complex manner than just adding
the two signals together.
The amplitude modulated signal is then ring modulated by the output of the Oscillators sec-
tion. Ring modulation causes the harmonics to be mixed in a manner similar to amplitude
