4.2.4 The Damper Module

The Damper module is used to attenuate rapidly the vibration of the string.

In a piano or harpsichord, this role is played by felts while for the violin or

the guitar, the performer’s ﬁnger is used to damp the string vibrations. Basi-

cally, the damper can be viewed as a mass/spring system acting on the string

as illustrated in Figure 12. The Mass and Stiff knobs are used to adjust these

parameters, which affect how the damper interacts with the string. These phys-

ical parameters can be modulated with the pitch signal from the Keyboard and

ﬁne-tuned over the whole range of the instrument. The Velocity knob is used

to adjust the velocity at which the damper is applied and released from the

string. This parameter can also be modulated with the pitch signal from the

Keyboard module. The last parameter of the Damper module is controlled

with the Damping knob and refers to the ability of the damper to absorb energy from the string.

Turning this knob clockwise will increase the damping exerted on the string by the damper.

Note that the Damper module responds to the sustain pedal signal via the Damper MIDI Con-

trol Change message (CC#64). In order for String Studio VS to respond to a sustain pedal, simply

set your synth or MIDI controller to send its sustain pedal signal via this MIDI Control Change

message.

4.2.5 The Termination Module

This module is used to model the fret/ﬁnger/string interaction as illustrated in Figure 13. In a real

instrument, this interaction is used to change the effective length of the string and thereby ﬁx the

pitch of the note played.
