The diagram below shows the results from high, medium and low settings of
the cut-o frequency when applied to the SAWTOOTH and SQUARE
waveforms.
The VCF FREQ range is from 50.0 Hz to 20000.0 Hz. The default VCF
FREQUENCY setting is 20000.0 Hz (fully open).
The fader position, current value and stored value for the VCF FREQ fader is
shown on the PROG screen. There is also a visualization of the lter curve as
shown below.
Note: The slope of the lter will update depending on the use of a 2-pole or
4-pole conguration.

8.5.2 VCF RES FADER
• The VCF RES fader controls the resonance of the lter. When resonance is
increased, the frequencies/harmonics/partials around the cut-o frequency
are emphasized. The resonance along with the lter slope help dene the
character of the lter.
The DeepMind 12 lter is capable of being driven into self oscillation. Unlike
many other synthesizers, the DeepMind 12 can guarantee an accurate pitch
even when the lter resonance is pushed to (and past) the point where the
lter starts to self-oscillate. When using this self-oscillating feature of the
VCF as a sound source, the VCF calibration ensures the correct response when
playing the entire scale of the keyboard. For more information please consult
the section on calibration later in this document.
The VCF RES range is from 0.0% to 100.0%. The default VCF RES setting is
0.0%.
The fader position, current value and stored value for the VCF RES fader is
shown on the PROG screen. There is also a visualization of the resonance as
