80 DeepMind 12D User Manual 8.5.3 2-POLE SWITCH 8.5.4 VCF EDIT SWITCH ON=2P / OFF=4P FLASHING=EDIT • This switch controls the configuration of poles used in the VCF. The 1. To access the VCF menu press the VCF EDIT switch. number of poles used in the filter determines the angle of the filters slope/ response curve. 2. The VCF EDIT switch will then start flashing and the VCF PARAMETERS menu is then shown: The VCF uses 4-poles, but can be switched into 2-pole operation. If configured for 4-pole operation the low-pass filter rolls off signals above the cut-off frequency at a rate of 24 dB/octave. When configured for 2-pole operation the low-pass filter rolls off signals above the cut-off frequency at a rate of 12 dB/octave. This can be useful to control the sonic character of the filter, 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) LEVEL (dB) FREQUENCY (Hz) 4-Pole 2-Pole The 2-POLE configuration can be On (2-Pole) or Off (4-Pole). The default program setting is Off (4-Pole). 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 affect how much VCF envelope modulation is applied. The harder you strike the keys, the more the filter 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 your external keyboard's Pitch Bend Wheel position will affect the cut-off frequency. The further you move the wheel forward from its central position, the more the filter will open and the brighter the sound will become, the further you move the wheel backward from its central position, the more the filter 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 of your keyboard will increase the LFO MODULATION DEPTH. This allows you to add LFO modulation of the filter frequency expressively while you play. The AFT-LFO-DEPTH range is from 0 to 255, and the default setting is 0.
