Vcf Edit Switch; Vcf Env Fader - Behringer DEEPMIND 12 User Manual

69 DeepMind 12 User Manual
This can be useful to control the sonic character of the fi lter as the 2-pole mode
will allow more of the signal above the cut-off frequency to pass and sound
brighter / more natural. The 4-pole mode allows less of the signal above the
cut-off frequency to pass and sounds deeper/ more unusual.
VCF POLES ( CUT OFF SLOPE)
FREQUENCY (Hz)
The 2-POLE confi guration can be On(2-Pole) or Off (4-Pole). The default program
setting is Off (4-Pole).

8.5.4 VCF EDIT SWITCH

FLASHING=EDIT
To access the VCF menu press the VCF EDIT switch.
The VCF EDIT switch will then start fl ashing and the VCF PARAMETERS menu is
then shown:
To navigate the options in the VCF PARAMETERS menu, use the UP, DOWN,
switches.
Selected parameters are adjusted using the -NO/+YES switches, the rotary knob
or the fader. The rotary knob has a click which allows very accurate control. The
fader allows rapid adjustment across the full range:
The following options are available in the VCF PARAMETERS menu:
BASS-BOOST - This option engages an analog bass boost circuit. This setting
follows the BOOST switch status.
VELOCITY-SENS - This option controls how much the velocity at which you strike
the keys will aff ect how much VCF envelope modulation is applied. I.e. the harder
you strike the keys, the more the fi lter will open and the brighter the sound will
become (unless the operation is inverted using the INVERT switch).
The VELOCITY-SENS range is from 0 to 255. The default VELOCITY-SENS setting
is 128.
4-Pole 2-Pole
P.BEND-FREQ - This option controls how much the PITCH BEND WHEEL position
will aff ect the cut-off frequency. I.e. the further you move the wheel forward
from its central position, the more the fi lter will open and the brighter the sound
will become, the further you move the wheel backward from its central position,
the more the fi lter will close and the darker the sound will become.
The P.BEND-FREQ range is from 0 to 255. The default P.BEND-FREQ setting is 128.
LFO-SELECT - This option allows you to select which LFO is assigned to the VCF
LFO MODULATION FADER.
You can select either LFO 1 or LFO 2. The default setting is LFO 2, which allows
you to use LFO 1 for voice modulation and keep the functionality separated. You
can of course use the same LFO to modulate the OSC and VCF if you desire.
AFT-LFO-DEPTH - This option controls how much the AFTERTOUCH pressure will
increase the LFO MODULATION DEPTH. This allows you to add LFO modulation of
the fi lter frequency expressively while you play.
The AFT-LFO-DEPTH range is from 0 to 255. The default AFT-LFO-DEPTH setting
is 0.
MW-LFO-DEPTH - This option controls how much the MOD WHEEL position will
aff ect the LFO MODULATION DEPTH. This allows you to add LFO modulation of the
fi lter frequency expressively while you play.
The MW-LFO-DEPTH range is from 0 to 255. The default MW-LFO-DEPTH setting
is 0.
LPF-TYPE - This option is the same as the 2-POLE switch on the surface. Any
changes on the surface will be refl ected here.
The LPF-TYPE confi guration can be 2-POLE or 4-POLE. The default program
setting is 4-POLE.

8.5.5 VCF ENV FADER

The VCF ENV fader controls the amount of VCF ENVELOPE modulation that will be
applied to the cut-off frequency value.
When the cut-off frequency is modulated by the VCF ENVELOPE each note will be
aff ected by the ADSR (and Curves) stages for the VCF ENVELOPE. You can use this
to apply subtle or aggressive modulation to the harmonic characteristics of each
note played for the duration they are playing.
When modulating the cut-off frequency using the VCF ENVELOPE, it is advised
to set the fader to a lower level when using normal polarity, and set it to a
higher level when using the INVERT function of the VCF ENVELOPE MODULATION
parameter.
When no ENV MODULATION is applied the fi lter cut-off frequency will stay fi xed
(unless other sources of modulation are applied).
The cut-off frequency setting can limit the modulation from the VCA ENVELOPE.
If the VCF FREQ fader is already at its maximum setting, and the fi lter is already
wide open then no positive modulation can take the cut-off frequency higher.
