The VCF-01 is a 2 pole resonating low pass filter with frequency modulation.


CONTROLS

FREQ

The frequency knob changes the cutoff frequency.

RES

The resonance knob controls the amount of feedback in the filter.

CV AMT

The control voltage amount knob applies the CV socket input to the frequency.


SOCKETS

IN

Signal input.

CV

Control voltage input for cutoff frequency modulation

OUT

Low pass output.

TYPE

Filter

FILTER TYPE

Low pass

FILTER SLOPE

12db per octave

FREQUENCY RANGE

0 hz to approx 7 khz


MORE INFORMATION

A low pass filter allows frequencies below the cutoff frequency to pass through while attenuating frequencies above the cutoff frequency.

High resonance values will emphasize the filter frequency and slightly reduce the amplitudes of all other frequencies.

FILTER SHAPE

TIP

You would typically filter waveforms with lots of harmonics such as sawtooth and square. Filtering a sine wave will have minimal effect.
