Set the desired transformation characteristics with the selectors, Log2, Log1, Exp1 or Exp2.
• As mentioned, the Shaper affects each single value of an incoming signal, not
the total level. To show this more clearly, take a look at the figures below. The
X-axis in the diagram represents the incoming signal values, and the Y-axis the
output values.
• If a sine wave is sent to the input of the Shaper, and the Log2 curve is selected,
the resulting wave on the output would be more like a square wave.
• If the Exp2 curve is selected, a sine wave on the input would result in a triangle-like wave on the out-
.

The Rectifier (diode processing) module
can be set to discard of any positive or
negative input levels, or if you want to
transform these to only positive or only
negative levels.

Sets the operation of the module. The first position discards of any negative input signal levels, the second
position discards of any positive input signal levels, the third position transforms (mirrors) any negative
signal levels to positive levels and the fourth position transforms (mirrors) any positive signal levels to neg-
ative levels. See also

A filter is one of the primary tools for coloring the sound in a synthesizer. It can attenuate and amplify
different frequencies in oscillator waveforms and other signals, and drastically change the timbre of the
sound. Most of the Nord Modular G2 filters can be dynamically controlled from various modulation
sources.
In Nord Modular G2 you have several different filter modules to choose from, ranging from traditional
LP/HP/BP filters to complex special filters such as the Vocoder and the Vocal filter.

There are one or more
Control
or
Dynamic Control/Audio
signal inputs for a modulation
source to control the cutoff frequency of the filter. There can also be a pitch modulation at-
tenuator next to the input of
Attenuator Type II
. If the attenuator knob has a triangle above
it, click it to select 1:1 keyboard tracking of the cutoff frequency if the input is connected to
the Note output of the Keyboard module (see
). See
for more info.
