Introducing The Filter

Now that you have been playing with the OSCILLATOR and are familiar with some of
the things it can do, return the knobs to the BASIC PATCH settings so that we can
explore the FILTER section.
The FILTER is just what it implies. It filters, or removes, aspects of the signal that is put
into it. The Steiner-Parker filter, originally designed by Nyle Steiner, allows for wide
ranging sounds and many sonic possibilities.

Low Pass Filtering

The BASIC PATCH has the FILTER set to full open in LOW PASS mode. This means that it
is not affecting the sound of the OSCILLATOR at all. In LOW PASS mode, having the
CUTOFF knob in the full clockwise setting, means that all frequencies will 'pass'
through it. Figure 3
See
With the BASIC PATCH set, play a note and listen to the sound as you turn the
CUTOFF KNOB counter clockwise. You will hear the sound get darker and darker until
it goes away totally.

High Pass Filtering

With the CUTOFF knob still all the way counter clockwise, move the MODE SWITCH to
HP; Figure 4 You should now hear the sound come back.
See .
This changes the filter to a High Pass Filter. Just as the name implies, it allows the
HIGH frequencies to pass though. With the knob in the full counter clockwise
position, the filter is allowing all frequencies above that setting to pass through it.
