The Impact of Cutoff Frequency on the ES2 Signal
The Cutoff Frequency (Cut) parameter controls the brilliance of the signal.
In a lowpass filter, the higher the cutoff frequency is set, the higher the frequencies of
signals that are allowed to pass.
In a highpass filter, the cutoff frequency determines the point where lower frequencies
are suppressed and only upper frequencies are allowed to pass.
In a bandpass/band rejection filter, the cutoff frequency determines the center frequency
for the bandpass or band rejection filter.
The Impact of Resonance on the ES2 Signal
The Resonance (Res) parameter emphasizes or suppresses portions of the signal above
or below the defined cutoff frequency.
In a lowpass filter, Resonance emphasizes or suppresses signals below the cutoff
frequency.
In a highpass filter, Resonance emphasizes or suppresses signals above the cutoff
frequency.
In bandpass/band rejection filters, resonance emphasizes or suppresses the portions
of the signal—the frequency band—that surround the defined frequency, set with the
Cutoff Frequency parameter.
Controlling Cutoff and Resonance Simultaneously in the ES2
Changing the Cutoff and Resonance controls at the same time is essential to the creation
of expressive synthesizer sounds.
