8.2 STEP FILTER
This is a dynamic filter where the resonance frequency is arpeggiated (stepped) continuously.
The number of steps is selectable from 4 to 8, and the amplitude of each step is freely adjust-
able. Tempo of the stepping can be tapped, with four selectable subdivisions. Again, four distinct
filter types are available to choose from.
PARAM knob - adjusts the tempo of the stepping.
RANGE knob - adjusts the amplitude of the steps.
MIX knob - adjusts the wet and dry mix.

In 'Random' mode the number of steps is fixed to 8 and the amplitude of the steps are
randomly modulated, this creates a nice 'jumpy' filter groove!
use the RANGE knob to adjust the amplitude of the step
Twist the MODES button to select the step whose amplitude you'd like to edit
