adjusted with the mod1 knob. The greater the amplitude, the greater the stiffness. This modulation
input is used, for example, when a variation of the stiffness of the mallet with the note played is
desired. When the knob is adjusted in its center position and when this input is connected to a pitch
signal, the stiffness exactly follows the pitch variation so as to ensure that the spectral content (or
color) of the sound produced by a structure is uniform when the pitch is varied. The third input
modulates the strength of the impact relative to the adjustment of the strength knob. This input is
generally connected to a velocity signal which allows you to increase the force of the impact. The
amplitude of this modulation signal is adjusted with the mod2 knob.
The default value of the following parameters is set at construction
• Strength: value of the impact force (value between 0 and 2).
• Stiffness: value of mallet stiffness (value between 1 and 20 000).
Note: See also Mallet.
6.51 Nor
The Nor module performs the inverse of the OR logic operation. The one output of this module is
either 1 (true) or 0 (false) depending on the values sent to the two inputs. This module has no front
panel. The following diagram shows the output value depending on the values in the two inputs.
Input signals are considered False (0) when smaller than 0.1 Volts and True (1) when greater
than 0.1 Volts.

1 1 0
1 0 0
0 1 0
0 0 1

6.52 Not
The Not module performs the logical not operation. The one output of this module is either 1 (true)
or 0 (false) depending on the values its one input receives. The module outputs false when the input
is true and outputs true when the input is false.
Input signals are considered False (0) when smaller than 0.1 Volts and True (1) when greater
than 0.1 Volts.
