Resonance
The resonance control emphasizes or suppresses signals around the cutoff frequency.
The figure below shows an ES1 sawtooth wave with a high resonance setting and the cutoff frequency set to 660 Hz.
This resonant filter setting results in much brighter and harsher signals close to the cutoff frequency. Frequencies below the cutoff point are not affected.
The result of using filter resonance is a change in the basic waveform shape and, therefore, the timbre of the sound.
Very high filter resonance settings can cause the filter to self-oscillate, resulting in the filter generating an audible sine wave.
