Filter Type: This control selects the basic sound of the filter.
Each filter type has a unique sound. You will find situations
where each one offers you a unique effect on a given signal.
The Low Pass Filter is the most commonly used filter type.
This is the kind of filter you will find on vintage synths and enve-
lope followers. It is useful
for controlling the amount
of harmonics or the
brightness of a signal. As
you sweep the frequency
control, try adding some
resonance to make the
cutoff frequency more
audible.
The High Pass Filter
will roll off the bass of
your signal making things
sound thinner as you turn
the frequency control to
the right.
The Band Pass Filter acts like Wah pedal and puts a peak
in the middle of your sig-
nal. (See Fig. 2) This is
great for highlighting cer-
tain frequency ranges or
for creating a sweeping
sound with the frequency
knob.
The Notch Filter works the exact opposite of the Band Pass
filter. Instead of a boost, it puts a notch in your signal, essential-
ly killing a narrow frequency band. This effect often sounds like
talking through a pipe.
For a more dramatic
Notch Filter effect use
turn the Resonance con-
trol all the way counter
clockwise into negative
Resonance to increase
the depth of the notch
and the distinctiveness
of the effect. It will also create unique sweeping sounds, (that
are similar to a phase shifter) when used in conjunction with the
LFO. For best Notch result put the Resonance knob fully count-
er-clockwise.
