Vermona Filter Lancet - analogue multimode filter - Manual (Page 10)

CUTOFF
This control manually sets the filter’s cutoff-frequency. This is the fre-
quency from which the audio signal is manipulated (filtered) with the fil-
ter's slope. In low pass mode (MODE LP) the filter is fully opened with
CUTOFF turned fully clockwise, closed when turned fully counterclock-
wise. In high pass mode (MODE HP), the principle of operation works
oppositely. When using the filter in bandpass mode (MODE BP), there is
no fully opened filter. Here, specific frequencies are always suppressed.
CUTOFF has a larger control knob intentionally. This is the most impor-
tant function of FILTER Lancet and turning this knob should be fun!
RESONANCE
Resonance is a feedback circuit within the filter that emphasizes the
CUTOFF frequency. Lower values will slightly color the sound, higher
values more significantly. With higher values, the filter will also start to
self-oscillate, generating a sine wave at the CUTOFF frequency.
NOTE:
Resonance in FILTER Lancet will easily reach self-oscilla-
tion and produce a constant sine-wave-like tone. It is
recommended, not to set the VCA to ON but preferably
use it through the envelope-generator (EG) or the enve-
lope-follower (EF).
Self-oscillation of the filter will reach a high volume within the last third
of the control. Typically, you would avoid these levels by not turning up
the control that far. The prominent resonance frequency will also be
audible at lower settings. However, the maximum level-settings are
useful when mixing the original with a little portion of the filtered signal
through the MIX control. Here, the distinctive self-oscillation will also be
heard at tiny mix amounts.
INT
The INT control sets the intensity of the CUTOFF frequency being con-
trolled by a modulation source. The MOD SRC switch (Modulation
Source) selects this source. The INT control works bipolar. Turning
clockwise from the center position results in upward CUTOFF modula-
