3. Controls

1 Frq.

With this control you adjust the Cut-Off Frequency f

above which the filter attenuates all frequencies. At 10,

the filter is fully open. The more you turn down this

control, the more the high frequencies are filtered. The

sound becomes mellower and less bright (see Fig. 1)

until at 0 the filter is completely shut, and there will be

no output signal at all.

2 CV 2 • 3 CV 3

For voltage control or modulation of the cut-off fre-

quency, use these CV inputs " and/or § (see Fig. 1).

Use attenuators 2 and/or 3 to adjust the control

voltage level.

4 Lev.

Use this attenuator to control the amount of signal

entering the filter input $.

If the filter's output distorts, turn this control

down, unless you deliberately want the sound

5 Res.

With this control you adjust the filter's resonance

(emphasis, Q ) - the parameter which emphasises the

frequencies around the cut-off point f

maximum setting, the filter becomes so resonant that it

goes into self-oscillation, and starts behaving like a sine

wave . You can take advantage of this effect, and use

the VCF as an additional oscillator.
