! CV 1

Socket CV 1 is the filter's standard voltage control

input, and works on the 1V / octave rule, like the

VCOs.

If you patch a modulation source (eg LFO, ADSR) to

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.

If you use the VCF as a sine wave oscillator, connect

Resonance

the pitch CV into this socket. Do the same if you want

the filter's cut-off frequency to track exactly with the

pitch of a note.

" CV 2

Sockets CV 2 and CV 3 are also voltage control

inputs for the filter. Unlike CV 1, you can control the

level of voltage - the intensity of modulation effect on

the filter - with attenuators 2 and 3.

$ Audio In

This is the filter's audio input socket. Patch in the

output from any sound source (eg. VCO, noise gene-

rator, mixer).

% Audio Out

Filter output % sends out the filtered signal.
