6.6 Shaper 6 PRESET PARAMETERS
6.6 Shaper
The shaper is a module located right after the mixer stage and allows additional processing
before the signal is routed to the analog filter. It offers a multimode filter that can be
configured as low-pass, band-pass or high-pass.
To access the shaper parameters, press the FILTER module button. If
you press the button more than once, the selection will cycle between filter
and shaper. The LED color indicates which module is selected:
Filter Shaper
In addition, the display will show the selected module briefly:

Make sure that the shaper module is selected.
In normal mode, the Cutoff, Resonance and Env A Amount parameters can be edited
via the first, second and third encoder. To edit the Pitch Tracking, Mode and LFO 2
Amount parameters, alternate mode has to be enabled via the ALT button.
6.6.1 Cutoff Frequency
Sets the frequency at which the separation between pass band and attenuation band takes
place.
ˆ
In low-pass mode, all frequencies above the cutoff frequency are attenuated.
ˆ
In band-pass mode, the cutoff frequency can be seen as center frequency. A band
around this center frequency is kept unaffected, while the rest outside will be atten-
uated.
ˆ
In high-pass mode, all frequencies below the cutoff frequency are attenuated.
6.6.2 Resonance
ˆ
In low-pass or high-pass mode, this parameter creates an adjustable ”bump” that
accentuates the frequencies around the cutoff frequency.
ˆ
In band-pass mode, it adjusts the size of the band around the center frequency.
6.6.3 Env A Amount
Determines how much the amplifier envelope (Env A) affects the cutoff frequency. Use
this to achieve a natural progression of the filter that corresponds to the volume of the
signal.
6.6.4 LFO 2 Amount
Sets the amount of LFO 2 modulation on the cutoff frequency.
