the plate thus shortening the decay time of the sound produced by the structure. When the signal is
greater than 0, dampers are raised. Note that this damping adds to the natural damping of the plate
itself. If this input is not connected to any other module, the default value is set at 0 which implies
that the plate motion will be damped. This input is, therefore, usually connected to a Constant
module to obtain undamped motion or to a Damper module or the gate signal from a Keyboard
in order to vary the damping while playing. The second input signal is the force signal exciting the
plate and the third is a pitch modulation.
The default value of the following parameters is set at construction
• Length: the length, in meters, of the plate.
• Width: the width, in meters, of the plate.
• Frequency: fundamental frequency, in Hertz, of the plate beam when there is no pitch modu-
lation signal or when its value is equal to 0. Note that the fundamental frequency is indepen-
dent of the size of the plate. The software automatically calculates the physical parameters
necessary to obtain the required fundamental frequency. The default value of this parameter
is 261.62 Hz which corresponds to the middle C (C3) of a piano keyboard. This setting is
convenient when controlling a Plate module with a Keyboard module.
• Decay: proportional to the decay time of the sound produced by the plate.
• Number of Modes: number of modes used to simulate the object. As the number of modes
is increased, the number of partials in the sound increases but also inevitably the calculation
load.
• Excitation point-x: x-coordinate, in meters, of impact point from the lower left corner of the
plate.
• Excitation point-y: y-coordinate, in meters, of impact point from the lower left corner of the
plate.
• Listening point-x: x-coordinate, in meters, of listening point from the lower left corner of the
plate.
• Listening point-y: y-coordinate, in meters, of listening point from the lower left corner of the
plate.

module.
6.62 Player
The Player module is used to read sound files from a disk. This module has one input and two
outputs, the latter being the left and right channel from the signal read from the sound file. When
the sound file is mono, both output pins carry the same signal. The outputs from the Player can
