$ QCV

This socket is the voltage control input for the filter's

resonance.

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

this input, the resonance of the filter will be modulated

by it: increases in voltage will increase the amplitude

of the frequencies around the filter cut-off point.

% Audio Out

Filter output % sends out the filtered audio signal.

System A - 100

5. User examples

The filter's cut-off frequency can be modulated in

various ways:

• VCF - LFO

Modulation of the cut-off frequency produces cycli-

cal changes of the

frequencies (c. 1 - 5 Hz), you get a "Wah-Wah"-

effect. Modulation in the audio range produces

interesting sounds; the same principles apply here

as with frequency modulation of the A-110 VCO

(see chapter 6).

• VCF - ADSR

Modulation by an envelope results in gradual

change of the sound spectrum. Typical uses

include filter sweeps, which slowly sweep through

the audio spectrum, picking out different harmonics

in turn.

• VCF - Keyboard CV

This modulation produces pitch-related filter ope-

ning.
