Programming Organ Styles (Style Menu); Adjusting The Tremulants (Tremulants Function) - Viscount Cantorum Duo Mode D'emploi

6. PROGRAMMING ORGAN STYLES (STYLE menu)

The Style indentifies the sound configuration of the organ, i.e. the actual voice activated by each stop. The
many organ styles allow the musician to use several sound configurations, as if several different
instruments were present at the same time in the same place.
The Cantorum Duo has four organ styles, each one refers to a particular aesthetic of sound: Baroque,
Barock, Romantic and Symphonic. As already described at point 10 of chap. 2, Styles can be selected
through the dedicated pistons: [BAR], [BRK], [ROM] and [SYM]. On the main video page, each time a
Style is selected its name appears on the display. All four styles can be customized: the user can adjust the
tuning difference among pipes, tremulant Speed and Depth for each section, stops volume and orchestra
voices.
To modify a Style, recall the desired Style, then select the STYLES field in the MAIN MENU. The
following page will appear:
The fields on this menu perform the following functions:
o ENSEMBLE: level of tiny natural differences in pitch between one organ pipe and another,
simulating the tuning error that occurs in the organ's pipes due to wear over time and variations in
temperature.
The values range from 0 (pipes perfectly tuned) to 8 (maximum pitch instability).
o TREMULANTS: adjust the speed and depth of the tremulant for each manual (par. 6.1).
o VOICES VOLUMES: set the volume for each stop (par. 6.2).
o ORCHESTRA: select orchestra voices (par 6.3).
To access a function, use the buttons [FIELD
corresponding field, then press [ENTER].
To quit the STYLE menu, press [EXIT].
NB
Any general combination and Tutti can recall the organ Style that was in use when the
combination was saved. However in order to save Styles to combinations, the corresponding
option of the COMBINATIONS function must be activated. For further information see par. 5.6.

6.1 ADJUSTING THE TREMULANTS (TREMULANTS function)

In a pipe organ it is of the utmost importance that the air pressure remain constant, so as to obtain a
steady and sustained sound. However, mechanical devices were introduced to generate periodical
variations in the air flow.
These variations created the "tremulant" effect on the sound, which made some lead registers more
pleasant, and the tone of the reeds colourful.
By using the [TREM I] and [TREM II] thumb pistons it is possible to enable and disable the effect in
question.
