6.2 The Guitar Modules 49
6.2.2 The Pick/Fingers Module
The Pick/Finger module allows one to control the excitation
of the string with a pick or fingers. The Stiffness parameters de-
termines the flexibility of the plectrum or in other words the re-
sistance it exerts against the string. Increasing the value of this
parameter mainly increases the amplitude of the sound. The
Edge
parameter is used to control the rounding of the edge of the plec-
trum. Turning this clockwise increases the sharpness of the edge
resulting in a brighter sound. The
Position
parameter allows one
to modify the pick position on the strings while playing. This is a
parameter used by guitarists to change the tone of the sound. In-
deed playing near the bridge results in a dryer and more metallic
sound while playing over the hole of the body or toward the fretboard results in a fuller sound. In
its leftmost position, the pick is very close to the bridge. Moving this knob clockwise moves the
pick toward the fretboard.
6.2.3 The Hammer Module
The Hammer module is used to control hammer-on and pull-off effects. Hammer-
ons and pull-offs are playing techniques used by guitar players to play legato or grace
notes. The hammer-on effect is obtained by first picking a note and then hammering
down another finger onto the same string at a higher fret. The pull-off effect is almost
the opposite of the hammer on. It is obtained by first picking a note and then sharply pulling-off
the finger from the fretboard in order to hear a second fretted note on the same string. The sounds
produced using these techniques are softer and less percussive than the ones produced by picking
the notes.
In Strum , hammer-ons and pull-offs are triggered when legato playing on the keyboard is de-
tected. The Amp knob is used to control the amplitude of the excitation when a hammer-on or
pull-off is triggered and therefore determines the strength of the effect. Turning this knob to the
left reduces the amplitude of the excitation while turning the knob clockwise increases it.
6.2.4 The Mute Module
The
Mute
module is used to control the sound of the string when it is muted. On
a guitar, fretted notes can be muted by decreasing the pressure applied by the fretting
fingers on the string. The guitarist can control the effect by applying more or less
pressure on the strings and obtain a percussive effect, also called scratching, by striking
the strings with the picking hand.
In Strum , scratching is achieved by using special down and upstroke strumming keys as ex-
plained in section 3.2. The resulting sound of this effect can be adjusted with the help of the Tone
