Modular
VCF In VCF audio input selector. With this switch in upper position 'Noise', white noise is the input
for the filter. With the switch in middle position 'Noise+ext.' , a combination of white noise and the
external audio signal applied on the 'ext. VCF In' socket feeds the filter's input. With the switch
in lower position 'ext.', only the external audio signal is being processed by the VCF.
VCF CV Input
VCF cutoff frequency modulation input. Modulation depth can be adjusted by knob
'VCF CVin' ; its polarity is invertable with switch .
VCF 1V/Octave CV Input The 1V/oct. tracking can be adjusted precisely by trimmer

external signal input for the VCF. This input allows an external audio signal to be
fed into the VCF. This signal may replace the internal noise source or can be combined with it;
depending on the position of switch 'VCF In' .
Note: This socket has no extra knob for adjusting its level. Due to the wide range of possible input
signals and filter settings it may happen that the filtered signal is distorted (with high Q setting and
an input frequency which is nearby the VCF's cutoff frequency) or is too low.
VCA CV in Input level control knob for the CV source applied on 'VCA CVin' controlling the
VCA's amplification (for its input signal selectable by switch 'VCA In' ) . In center position (denter
locked) the level is 0 and there is no CV modulation of the VCA. By turning the knob clockwise, the
CV will modulate the selected input signal. By turning this knob counterclockwise, the inverted CV
modulates the VCA's input signal ('polarizer').
Offset VCA offset control. With this polarizing control knob either a positive or negative voltage can
be added to the VCA's CV input. In center position (denter locked), the offset voltage is 0. By
turning the knob CW, a positive voltage with range up to +5V will be added, by turning the knob
CCW, a negative voltage up to -5V is addable. By turning this knob CW, the pure, unmodulated
VCA's input signal (selectable by switch 'VCF In' ) will be provided on the VCA's output 'VCA Out'
- with variable amplification. In combination with an applied CV on 'VCA CVIn' , a negative
offset voltage added (turning the knob CCW) may be used to shift the VCA's operation point – so
that only from a certain amount of positive input CV begins to open the VCA (Example see chapter
6. Patches
Example 4).
VCA In Signal input selector for the VCA. The position of this switch determines which signal is
being processed by the VCA.
