Mix

Mix control 5 adjusts the relative amounts of low-pass
and high-pass signals appearing at the LP/HP mix
output %.

You can move from pure low pass (LP position on the
control) via asymmetrical / symmetrical / asymmetrical
notch to pure high pass (position HP).

Audio In

This socket is the filter’s audio input. Patch the
output of a sound source (such as a VCO, noise
generator or mixer) into it.

"

CV 1

Socket CV 1 is a voltage control input for the filter
frequency
. It works approximately to the 1 V / octave
standard (like a VCO). Due to the simple Wasp filter
design the control scale is not very precise.

If you patch a modulation source (eg LFO, ADSR) into
this input, the cut-off frequency of the filter will be
modulated by its voltage: ie, the sound color changes
according to the voltage put out by the modulator.

§

CV 2

Socket CV 2 is another voltage control input for the
filter.
Unlike CV 1, you can control the level of voltage
- the intensity of the modulation effect on the filter -
with attenuator 3.

BP Out

This is the band-pass output.
