CUTOFF
The FILL control is used to change the filter cutoff frequency. As you turn the knob, the LEDs
indicate the active area of the filter. The filter characteristics can also be seen visually. Only the
filter bands with lit LED are audible.
EXAMPLE OF FILTER MODULATION
Example: Adjusting the lowpass cutoff manually
- Set the CUTOFF (FILL knob) to the middle position
- Set FILTERTYPE to Lowpass (VARIATION knob at 9 o'clock).
- Turn SMOOTH to maximum (ENVELOPE knob fully clockwise)
Now you can use the CUTOFF control (FILL control) to move smoothly through the individual fil-
ter bands like a low-pass filter. You can see this from the glowing LEDs of the filter channels.
The filter type algorithm automatically regulates the volume of the individual filter bands, crea-
ting the effect of a low-pass filter. The other filter types work the same way.
Try them out and listen to the different effects.
SMOOTH
The ENVELOPE knob changes the smoothing of the band sweep with the cutoff control. It can
be softly blended from unsmooth to smooth. With an unsmoothed setting, the bands jump
straight on. With a smooth setting, the bands flow smoothly into one another.
All three functions can also be controlled via the corresponding CV inputs.
