A-105 / A-122

At close to maximum resonance, the filter starts to

self-oscillate, and behaves like a sine wave oscilla-

tor. Thanks to this effect, you can use the filter as an

independent tone source.

4. In / Outputs

! Audio In

This is the filter's audio input socket, where you

patch in the output from any sound source.

" FCV 1

Socket FCV 1 is a voltage control input for the filter.

re s onan ce

It works on the 1V / octave rule, like the VCOs.

If you connect the output of 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.

frequency

§ FCV 2

Socket § is also a voltage-control input for the filter.

Unlike on socket ", though, you can adjust the level of

voltage by using the attenuator 3 , and thus control the

intensity of modulation effect on the filter.

If you use this VCF as a sine wave oscillator,

connect a pitch control voltage to this input.

Do the same if you want the filter's cut-off

frequency to track exactly with the pitch of a

note.
