VCF
VCF: Voltage Controlled Filter
The low-pass filter creates a brighter or darker sound by selectively
filtering certain parts of the harmonic spectrum of the sound generated
by the oscillators and the noise generator.
CUTOFF knob
This knob is used to set the cutoff frequency (the frequency at which
the filter is applied).
Turning the knob to the left will lower the cutoff frequency, and turn-
ing the knob to the right will raise the cutoff frequency.
If the CUTOFF value is set too low, the volume may be extremely
low.
RESONANCE knob
Also known as Peak or Q, the RESONANCE control adds additional emphasis to the overtones
occurring at the CUTOFF frequency, giving a distinctive character to the sound.
Turning the knob to the right will emphasize the harmonic content, increasing the resonance ef-
fect.
Low resonance value
The overtones that are emphasized will change depending on the cutoff frequency. For
Tip:
this reason, it's good to adjust the CUTOFF knob while adjusting the RESONANCE knob.
When emphasizing the overtones in this way, the sound may distort depending on the
cutoff frequency or the input audio.
DRIVE switch
Sets the distortion effect produced by the drive circuit, in three stages.
0% (switch in the lower position): no drive effect.
50% (switch in the center position): drive effect will be set at half strength.
100% (switch in the upper position): drive effect will be set at maximum.
KEYTRACK switch
Key tracking allows the note played on the keyboard to influence the cutoff frequency of the filter.
0% (lower position): No keyboard tracking will be applied.
50% (center position): Keyboard tracking will affect the cutoff frequency, but at only half the
amount produced by 100%. For example, playing the C5 note on the keyboard will produce a har-
monic that is an augmented fourth higher than the cutoff frequency of C4.
100% (upper position): The cutoff frequency will change at the same rate/slope as the pitch of the
keyboard, centered on C4. For example, pressing the C5 key will give a cutoff frequency one octave
higher than the C4 key.
