Noise Synth
Key Tracking
Mode
Lowpass, Highpass, Bandpass. This selects whether the filter will cut high
frequencies (Lowpass), cut low frequencies (Highpass), or cut all frequencies above
and below the cutoff point (Bandpass).
Lowpass. Frequencies above the cutoff will be attenuated, and frequencies below
the cutoff will pass through unchanged.
Highpass. Frequencies below the cutoff will be attenuated, and frequencies above
the cutoff will pass through unchanged.
Bandpass. Frequencies both above and below the cutoff will be attenuated, and
only frequencies right at the cutoff will pass through unchanged.
Type
4 Pole, 2 Pole, 2 Pole > 2 Pole. This parameter selects the amount of frequency
attenuation in the filter, and the character of the resonance.
4 Pole. This is a 24dB per octave filter. Of the three types, the 4 Pole offers the
greatest attenuation of frequencies beyond the cutoff, coupled with a resonance
slightly more delicate than the 2 Pole type. Many classic analog synths used this
general type of filter.
2 Pole. This is a 12dB per octave filter. Compared to the 4 Pole, this offers
significantly less attenuation of frequencies beyond the cutoff, but with slightly
more pronounced resonance.
2 Pole > 2 Pole. This is two 12dB per octave filters in series. Of the three types, this
offers by far the most extreme resonance effect. Compared with the 4 Pole, it has
just a little less attenuation of frequencies beyond the cutoff.
