261.6 Hz, which corresponds to the C3 key on a piano (middle C). The range switch transposes the
pitch one or two octaves up or down. The reading on the counter gives the frequency of the output
signal, in Hertz, when there is no modulation signal. The second input is used to give the module
an estimate of the pitch of the original signal in order to minimize the artifacts it introduces. The
convention followed here is 1 Volt/octave where a value of 0 Volt is C3 (middle C on the piano). For
example, A3 is equivalent to a value of 9/12 Volts since this note is located 9 semitones above the
C3. This input is usually connected to a Constant module. If you are not certain of the pitch of the
original signal, you can use a Constant followed by a Volume module in order to tune this input
signal. Finally the third and fourth input signals are used to modulate the pitch variation relative to
the setting of the coarse, fine and range knobs and selectors. The gain of these modulation signals
are controlled with the mod1 and mod2 knobs. The total modulation signal is the sum of the two
inputs each multiplied by the gain corresponding to its respective mod knob. When the knobs are in
the center position (green LEDs on), the gain equals 1 and the pitch variation is 1 Volt/octave. This
position is used to play an equal temperament scale when connecting the output of a Keyboard.
Typical Use
In the example of Figure 82, a sample from a Player module is pitch-shifted with a Shifter, the
final pitch being controlled by the Keyboard. The pitch of the original sample is adjusted with a
Constant module.

6.76 Single Gate Sequencer
The Single Gate Sequencer module enables you to record sequences of gates. This module in
itself does not produce sound but is used, usually instead of a Keyboard module, to trig other
modules such as a Player. This module is a 16-step sequencer, which means that it plays se-
quences or patterns of 16 notes in loop. Sequences can be set to have 1 to 16 steps. Because each
