8.5.3 2-POLE SWITCH
• This switch controls the conguration of poles used in the VCF. The number
of poles used in the lter determines the angle of the lters slope/response
curve.
The VCF uses 4-poles, but can be switched into 2-pole operation. If
congured for 4-pole operation the low-pass lter rolls o signals above
the cut-o frequency at a rate of 24 dB/octave. When congured for 2-pole
operation the low-pass lter rolls o signals above the cut-o frequency at
a rate of 12 dB/octave.
This can be useful to control the sonic character of the lter, as the 2-pole
mode will allow more of the signal above the cut-o frequency to pass and
sound brighter / more natural. The 4-pole mode allows less of the signal
above the cut-o frequency to pass and sounds deeper/ more unusual.
The 2-POLE conguration can be On (2-Pole) or O (4-Pole). The default
program setting is O (4-Pole).
ON=2P / OFF=4P

8.5.4 VCF EDIT SWITCH
1. To access the VCF menu press the VCF EDIT switch.
2. The VCF EDIT switch will then start ashing and the VCF PARAMETERS menu
is then shown:
3. To navigate the options in the VCF PARAMETERS menu, use the BANK/UP or
BANK/DOWN switches.
4. Selected parameters are adjusted using the -/NO or +/YES switches, the
rotary knob or the DATA ENTRY 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 setting of the BOOST switch below the HPF Fader.
• VELOCITY-SENS - This option controls how much the velocity at which you
strike the keys will aect how much VCF envelope modulation is applied.
The harder you strike the keys, the more the 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, and the default setting is 128.
• P.BEND-FREQ - This option controls how much the PITCH BEND WHEEL
position will aect the cut-o frequency. The further you move the wheel
forward from its central position, the more the lter will open and the
brighter the sound will become, the further you move the wheel backward
from its central position, the more the lter will close, and the darker the
sound will become.
The P.BEND-FREQ range is from 0 to 255, and the default setting is 128.
• LFO-SELECT - This option allows you to select which LFO is assigned to the
VCF LFO MODULATION FADER, 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 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 lter frequency expressively while you play.
The AFT-LFO-DEPTH range is from 0 to 255, and the default setting is 0.
