Analogue 12 dB
multimode filter
(SHIFT+ANA12dB)
The analogue 12 dB multimode filter, like its digital counterpart, has
the three filter functions lowpass, bandpass and highpass. The filter
sounds quite similar to its digital copy, but adds a certain unbridled
behavior to the signal processing.

Button Knob/Button Description
- - -
CUTOFF
Use this knob to set the desired filter frequency.
- - -
RESONANCE Use this knob to adjust the resonance of the filter. Resonance
is the feedback of the filter output to the filter input. This
feedback causes an amplification of the output in the range of
the cuto
ff frequency. This intensifies the e ff ect of the filter
sound. Resonance can lead to feedback oscillation.

CUTOFF
MOD
Here you can set how much and with which polarity a control
voltage at the cuto
ff CV input modulates the filter frequency. In
the middle position, the modulation depth is 0. To the left, the
e
ff ect of the control voltage is inverted - a higher voltage
lowers the filter frequency. Right of the center an increaseing
the control voltage increases the filter frequency.
SHIFT
KB-SCALE
This is a MIDI parameter. Set up how much higher notes on
the keyboard control the filter frequency. The middle position
is neutral. Higher notes will open the filter more than lower
notes at positive values.
- - -
EG-DEPTH Here you can set how much and with what polarity the cuto ff
frequency of the filter is controlled by the ADSR envelope
voltage. In the middle position, the envelope is neutral and
causes no sound changes. In the right part of the scale, a
higher voltage value at the envelope output produces a higher
cuto
ff frequency in the filter. In the left scale area, the behavior
is exactly the opposite. A higher envelope voltage lowers the
cuto
ff frequency.
SHIFT
VELOCITY This parameter is a MIDI parameter. The velocity of the MIDI
note controls the cuto
ff filter frequency if desired. With [SHIFT]
& VELOCITY you can adjust the strength of the dynamics
control. Positive values cause the filter frequency to increase
as you play the notes more strongly.
LP With the LP button you can mute and unmute the lowpass
filter output of the active filter. When the output is opened, the
LED above the button lights up.
SHIFT
DIG12dB Use [SHIFT] & [DIG12dB] to select the digital multimode filter.
This filter is selected by default at INIT sounds!
- - -
BP Use the [BP] button to activate or mute the bandpass filter
output of the active filter. When the output is active, the LED
above the button lights up. This button has no function on the
24dB lowpass filter.
