With the F
REQUENCY
1 knob you set the cutoff frequency (or center frequency in BP and BR mode). If
you for example select a lowpass (LP) filter and turn the F
REQUENCY
1 knob clockwise, a more and more
high-frequent signal will be output from the filter.
Note that if the EnvAmt value is above zero, turning the F
REQUENCY
1 knob might not change the sound
as expected.

The slope of a filter determines how steep the frequency attenuation curve is. In Single Filter Modes in
Nord Lead 3 you can select between 6 dB/octave (1-pole), 12 dB/octave (2-pole) and 24 dB/octave (4-
pole) slopes for the LP (lowpass), HP (highpass) and BP (bandpass) filters. Press the F

This is the classic “synth filter” slope used in the Minimoog and Prophet-5 among others. It cuts out fre-
quencies rather drastically, 24 dB per octave. A 24 dB filter is also known as a 4-pole filter.

The 12 dB/octave slope leaves more harmonics than the 24dB variation discussed above. This type of
filter has been used in various early Oberheim synthesizers and others. A 12 dB filter is also known as a
2-pole filter.

The 6 dB/octave slope is very gentle and doesn’t cut out very much in the frequency spectrum. A 6 dB
filter is also known as a 1-pole filter and is the simplest type of filter.

The Resonance parameter is used to further adjust the characteristics of the Filter. If you are using the
HP, LP, CLASSIC or DIST LP filter types, increasing the Resonance will emphasize frequencies around
