Module A-123 (VCF 4) is a voltage-controlled high-

pass filter, which filters out the lower parts of the

sound spectrum, and lets higher frequencies pass

through.

The cut-off frequency determines the point at which

filtering takes effect. You can control this manually, or

by voltage control (filter modulation, for instance by

an LFO). Two CV inputs are available.

The cut-off slope is -24 dB/octave. The circuitry uses

a Curtis CEM 3320 chip.

Voltage controlled resonance: on the VCF 4, reso-

nance can be controlled not just manually, but by

voltages as well, right up to self-oscillation. In this

case, the filter behaves like a sine wave oscillator.
