VCF (Voltage Controlled Filter)
a . INITIAL FILTER FREQUENCY slider . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .[10Hz…10KHz]
Broadly adjusts the cutoff frequency of the LPF (low-pass filter).
Moving the slider toward the left cuts the high-frequency range of the input
signal, producing a softer tone. Moving the slider toward the right produces a
harder and brighter tone.
The frequency range is an approximate value.
b . FINE TUNE slider
Finely adjusts the cutoff frequency
of the LPF.
c . RESONANCE slider
Adjusts the filter resonance level.
This modifies the tonal character by
boosting the overtones in the region
of the cutoff point. As you raise the
slider, self-oscillation (a state in which
the VCF itself produces a sound) will
occur starting at a certain point.
d . TYPE switch . . . . . . . . . . . . . . . . . . . . . . . . . . . . [ , ]
Selects the type of VCF.
TYPE I: ARP 2600 early models
TYPE II: ARP 2600 late models
