In high-pass mode, partials above the cutoff frequency remain unchanged, while the
partials below the cutoff are attenuated.
Figure 25
The cutoff frequency in any of these filter types does not have to be static; controlling it
with other devices like a keyboard (keyboard tracking), an LFO or envelope generator
creates dynamically-changing and interesting timbres.
Resonance or emphasis
Figure 26
Resonance is a filter’s ability to amplify or emphasize partials that are close to the
cutoff frequency, thus creating a peak in the spectral response. This parameter can
be increased up to a point where the filter no longer acts like a mere filter, but starts
to oscillate on its own.
