4-5: String Main
4-5a: Excitation
The Excitation is the force that makes the string start to
vibrate. For a physical string, this might be a guitar
pick, a fingernail, a hammer on a clavinet, a plectrum
on a harpsichord, and so on.
Position [0…100.0]
This models the position of the excitation (such as the
pluck) along the string, which has a strong effect on the
timbre.
Important: the Tone parameter, below, must be non-
zero in order for Position to have any effect.
0.0 is one end of the string, at the bridge; 100.0 is the
other end of the string, at the nut (just before the
headstock). Usually, values between 8.0 and 25.0
should work well.
50.0 is the middle of the string. The timbres of different
values are approximately symmetric around this
position, except for very near the ends of the string. In
other words, 60.0 produces a similar timbre to 40.0,
75.0 is similar to 25.0, and so on. The delay between the
excitation and the pickups will change, however.
Excitation Position
How Position affects the timbre
Depending upon the Position, some overtones will be
emphasized, and others de-emphasized. At specific
positions, certain overtones will disappear completely,
as detailed below.
You can also think of the Position as a fraction of the
total string length. For instance, 50.0 means that the
excitation is half-way along the string; 33.3 means that
excitation is 1/3 of the way along the string; 25.0 is 1/4
of the way along the string, and so on.
Reaching back into math class for a moment, the
number under the fraction is called the denominator.
For instance, the denominator of 1/5 is 5.
