The slope of these curves is determined by the attraction capacity of the “poles”. The S
Series can have two 2-pole filters or one 4-pole filter. The 4-pole filter creates a clearer
slope and consequently a fuller and more aggressive sound.
Resonance enhances the frequencies in close proximity of the Cutoff Frequency, rendering
the filter curves more complex:

Resonance was a very typical feature of classic analog synthesisers. As an example, listen to
the Sound Invasion 82-2.

The two filters of the S Series can be also be considered as two band equalizers and can be
programmed accordingly.
