remulant effect
remulant effect
In pipe organs, it is of fundamental importance for the air pressure to be constant in order to obtain an
even, "sustained" sound. However, a number of mechanical devices were introduced to generate a
number of periodic variations of varying intensity in the air flow.
These variations produced a "tremulous" effect on the sound, which made a number of solo stops (such
as the VOX HUMANA) more pleasant on the ear, and gave added expression to the wind stops.
You can press the
TREMULANT
button (on the instrument's front panel) to enable or disable this effect.
The effect is activated when the LED is on.

The CM-100 allows you to adjust the two fundamental parameters that set the character of the tremu-
lant effect: the
SPEED
(modulation speed) and the
DEPTH
(modulation depth). You can also decide on
which of the module's voices the tremulant effect is to act (see advanced manual for the relative proce-
dure).
To set the modulation speed and depth, proceed as described below:
Locate on the instrument's Main page
Press the
SETUP
button
Use the cursor keys to select the "
TREMULANT
" option
Press the
ENTER
key and the following video page will appear on the display
Use the cursor
S
and
T
keys to select the field you require and turn the encoder to enter the values of
your choice: when the operation is complete, the display wll return to the main page.
TREMULANT DEPTH:13
TREMULANT SPEED:14
