Parameters
6.6.3
The Hammer Module
The
Hammer
module is used to control hammer-on et pull-off effects as explained
in section 6.2.3. In
Strum
, hammer-ons and pull-offs are triggered when legato playing
on the keyboard is detected. The three parameters of this section are
Tone
,
Amp
and
Velocity
. The
Tone
knob is used to set the harmonic content of the excitation produced
by the finger moving on the string as explained above. Turning this knob to the left
results in a smoother sound while turning it clockwise results in a sharper sound. The
Amp
parameter controls the amplitude of the excitation generated by hammer-ons and
pull-offs.
6.6.4
The Mute Module
In
Strum
, strings are muted when using the muffled downstroke or upstroke
strumming keys or, in auto-strum mode, when a note is released on the key-
board. This reproduces the muting effect obtained by guitarists by releasing the
pressure on the notes held by the fretting hand. The pressure applied on a given
string is controlled using the
Contact
knob. In its leftmost position, the contact
is very light and one can slightly hear the sound of the open string. When this
knob is in its rightmost position, the pressure between the finger and the string is
strong and one can hear the pitch of the fretted note. In its middle position, the
string is muted efficiently and one can, depending on the fret where the finger
is located, hear harmonics ringing. The tone and decay time of these harmonics
are set using the
Tone
and
Decay
knobs which fix the decay time and the spectral content of these
tones respectively. When muting a string it takes a little time for the guitar player to release the
pressure on the finger on the string in order to place them in muting position. This time is set using
the
Time
knob and the release time is increased by turning the knob clockwise.
6.6.5
The Palm Module
In
Strum
, palm muting is achieved by using the palm muted downstroke and up-
stroke keys. The resulting sound of this effect can be adjusted with the help of the
Decay
and
Tone
parameter. The
Decay
knob is used to set the decay time of the sound
when the strings are palm muted. In other words, it controls the amount of overall damp-
ing induced by the picking hand. Turning this knob clockwise increases the decay time.
The
Tone
knob controls the amount of high frequencies in the resulting sound relatively
to the amount of low frequencies or in other words the tone of the sound. Turning this
knob clockwise increases the amount of high frequencies in the sound.
