Notch+LP: To select this type of filter, press the Filter Type button until both the LP 12 and LP 24 buttons
light up.
A notch (or band reject) filter can be seen as the opposite of a band pass filter. It cuts off frequencies in
a “mid-range” band, letting the frequencies below and above through. However, a plain notch filter is
not very musically useful, since it often lets too many frequencies through, resulting in a very sharp, harsh
sound. Therefore, the notch filter in Nord Lead is combined with a 12dB Lowpass filter, resulting in a filter
curve that looks like this:
The audible result of this filter combination is a sound with plenty of body, some of the upper mid-range
“bite” removed but a certain amount of high frequencies still present. This type of sound could be very
useful for soft, yet clear pads, etc.
The special characteristics of the Notch+LP filter will be most obvious with low Resonance settings.
Frequency
This is the overall control for which part of the frequency spectrum the filter should operate.
▼
If you for example select the 24dB filter and turn the Frequency knob clock-wise, more and more high-
frequency material will be allowed to pass through the filter.
Please note that if the Envelope Amount setting is raised from its full left position, turning the Frequency
knob might not change the sound as expected. For more information, see below.
