VOLTAGE CONTROLLED FILTER (VCF) (Continued)
CUTOFF
The CUTOFF knob specifies the Frequency at which the Filter begins to
attenuate (or reduce) sound in either the Low Pass or High Pass mode.
NOTE: The 4-pole Ladder Filter provides 24dB of attenuation per octave
beginning at the Filter’s Cutoff point.
LOW PASS MODE
As the Filter CUTOFF knob is turned to the right, the top end of the Filter
will open, resulting in a brighter and more articulate sound, while retaining lower frequency harmonics.
As the Filter CUTOFF knob is turned to the left, the Filter will close, resulting in a thicker or dark sound.
HIGH PASS MODE
As the Filter CUTOFF knob is turned to the right, low frequency harmonics are removed, creating
a bright and more cutting sound. As the Filter CUTOFF knob is turned to the left, low frequency
information is allowed to pass while retaining a bright upper spectrum of sound.
WARNING: The Filter CUTOFF knob can be set manually from 20Hz to 20kHz — roughly the same range
as human hearing. Certain Filter and Modulation settings can cause DFAM to seem as if it is not making
sound. If you think this is the case, set the Filter CUTOFF knob and the VCF EG AMOUNT knob to center
position. If this does not resolve the issue, try setting the VCF switch to LP. If this still does not resolve
the issue, we recommend going back to the Default settings found on page 8.
RESONANCE
The RESONANCE knob determines how much signal is routed from the Filter’s
output back to its input. As the RESONANCE knob is turned to the right, a
peak or harmonic boost at the Filter’s Cutoff frequency is created and bass
frequencies may be attenuated.
TIP: Resonance settings above 3 O’clock in LOW PASS mode will cause the Filter
to self oscillate, creating a Sine Wave that can be used as an additional sound
source. (See preset Filter As An Oscillator on page 35.)
NOTE: In HIGH PASS mode, the
RESONANCE knob does not have the
same scaling as in LOW PASS mode.
With the RESONANCE knob set to its
maximum position, self-oscillation
begins with the Filter CUTOFF knob
set to approximately 1kHz. This is normal.
