The diagram below shows the response of a typical low pass lter. Frequencies above the cut-
off point are reduced in volume.

In addition to the traditional low-pass lter type, there are also high-pass and band-pass types.
On Circuit Mono Station, the Filter type is selected with the Shape switch

.
A high-pass lter is similar to a low-pass lter, but works in the “opposite sense”, so that it is
frequencies below the cut-off point which are removed. Frequencies above the cut-off point are
passed. When the Filter Frequency parameter is set to minimum, the lter is completely open
and no frequencies are removed from the raw Oscillator waveforms.
