resonance: resonance around the center frequency.
6.74 Selector2, Selector3 and Selector4
The Selector module comes in 3 flavors: Selector2, Selector3 and Selector4.
These modules have 2, 3 or 4 inputs respectively and one output. The purpose of
these modules is to connect the input corresponding to the position of the knob on the
front panel to the output.
Typical Use
Selector modules can be used when one wants to change the cabling of a synth. It can
be useful, for example, to be able to choose between an ADSR or a LFO to modulate
the cutoff frequency of a filter.

a Vlowpass2 filter.
6.75 Shifter
The Shifter module is used to change the pitch of an audio sig-
nal. It functions similarly to analog hardware where a magnetic
tape is scrolled in front of a two head system. In this way the pitch
of the signal is changed without affecting the duration of the signal
(unlike the effect obtained by simply slowing down or accelerating
a tape).
This module has one output, the pitch shifted signal, and four
inputs. The first input signal is the audio signal to be shifted. The
pitch shift is adjusted with the coarse and fine knobs and the range
switch. When the two knobs are in their center position (green LEDs on for the coarse knob), the
range switch is set to 8 and there is no modulation signal, the playing frequency has a value of
