24 Parameters
The Key knob is used to modulate the amount of noise depending on the pitch of the notes
played on the keyboard. In its center position, the amount of noise is the same for all notes and
equal to the value set by the Noise knob. When turned to the left, there is more noise for low notes
than high notes. Turning the knob to the right has the opposite effect and the noise component is
higher for high notes than low notes. Note that the Noise parameter can be adjusted directly from
the Play view.
5.2.2 The Fork Module
The Fork module is at the heart of the sound generation mechanisms of the Lounge Lizard EP. The
fork is the component that produces sound after being excited by the hammer. It has roughly the
shape of a tuning fork with a small branch called the Tine and a larger one the Tone bar.
The Tine Bar
The tine is where the hammer hits the fork.
It produces a high metallic sound very important
for clear electric piano sounds.
The amplitude of the tine signal present in the
final sound from the fork is controlled with the
help of the Tine knob. Turning the knob clockwise increases the presence of the tine in the final
sound. The amplitude of the tine signal can be modulated with the pitch of the note played using
the Key knob. Turning this knob to the left will increase the presence of the tine in low notes while
decreasing it for high notes. Turning this knob to the right has the opposite effect and increases the
presence of the tine in high notes while decreasing it in low notes. In its center position the volume
of the tine is uniform across the whole range of the keyboard.
The timbre of the tine bar can be adjusted with the Color knob which controls the relative
amplitude of low and high partials in the spectrum of the sound produced by the tine bar. Turning
this knob to the left will favor lower harmonics while turning it to the right will increase the relative
amplitude of the high harmonics present in the spectrum.
The Decay knob is used to adjust the time taken by the tine to fade out when a key is depressed
on the keyboard and a note is held. Turning this knob clockwise increases the natural decay time
of the oscillations.
The Tone Bar
The tone bar is the biggest part of the fork, it is connected to the tine and starts to oscillate when
the hammer hits the tine. The Tone knob is used to control the amplitude of the signal from the
tone bar present in the final sound. Turning this knob clockwise results in a louder sound from the
