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
