4.2 The Piano Module
The Piano module is used to select the type of pi-
ano which will be played. A selection of 4 different
instruments is available, three Rhodes-like pianos and a
Wurlitzer-like piano. Switching from one instrument to
the other is achieved by changing the position of the se-
lector knob.
The reference pitch of the keyboard can be adjusted
with the Tune knob. When in its center position (green LED on), the reference
note of the keyboard is A4 set at 440 Hz. Turning this knob counter-clockwise will
lower the pitch of this reference note while turning it to the clockwise will increase
it. Note that the pitch knob can be set directly to its center position by clicking on
the green LED.
4.3 The Tremolo Module
The Tremolo module, introduces low frequency amplitude
modulation, or tremolo, in the sound. This is an effect exten-
sively used with electric pianos. The effect is switched on or
off by clicking on the green LED in the upper right corner of
the module.
The stereo button is used to determine if the tremolo is
mono or stereo. When the button is depressed, the tremolo is
on and in stereo mode. In this mode, the sound bounces with a 180 degrees phase
from left to right. When the button is its off position, the tremolo is in mono mode
and is the same on the left and right channels.
The Depth is used to set the amount of modulation in the amplitude of the
signal. In its leftmost position, the amplitude is not modulated and turning the
knob clockwise gradually increases the amplitude of the modulation.
The Speed knob controls the frequency of the modulation. Turning the knob
clockwise increases this frequency and results in a faster modulation rate.
4.4 Damper
Although it is not visible on its interface, the Lounge Lizard Session engine in-
cludes a damper module which simulates the production of noise when dampers
