TREMULANT SPEED AND DEPTH
With this control it is possible to regulate the Tremolo SPEED and DEPTH, for each section (Swell and Great).
These controls affect the amplitude modulation as well as the frequency modulation.
VALUE RANGE:
SPEED: from 2.0 to 6.3 Hz
DEPTH: from 1.0 to 6.0 dB
Enter the control in the desired section (Swell / Great), as illustrated in SYSTEM PANEL N. 2. Insert (by means of
the organ tablets) one or more stops of your choice, together with TREMOLO. It is advisable to attempt separate
adjustments for flue stops and reed stops, in order to obtain a correct result valid for both families.
