INTONATIONS
The organ has 12 intonations divided into four styles: Romantic (ROM), Symphonic (SYM), Baroque
(BAR) and Historic (HIS) and three variations per style: Standard, Solo (SOLO) and Trio (TRIO).

PRE-PROGRAMMED MEMORY LOCATIONS
Pre-programmed memory locations are available by operating pistons PP to T and PL. These seven
memory locations have factory settings (presets) appropriate for the quiet pianissimo to the loud tutti
and the classic plenum.
Calling up a pre-programmed memory location:
Press a pre-programmed memory location (PP-T or PL). The active stops light up.
CAPTURE MEMORY
Through use of the capture memory, a registration can be made active with just one piston. The
capture memory consists of 75 levels. These levels can be seen on the display (Mem:..). Each level has
eight memory locations (pistons 1-8). The 600 capture memory locations are not pre-programmed
and can be programmed by the musician.

VOLUME CONTROLS
Organ: You can adjust the volume of the organ with the ORGAN volume control.
Cathedral: The reverb volume can be adjusted smoothly with the CATHEDRAL volume control.
Expression pedals: In the standard version the organ has two expression pedals. One is configured as
a swell pedal for the Swell, and one is configured as a crescendo pedal. With use of the Johannus
Menu, function ‘Expression Pedals’, the function of the expression pedals can be changed.
Using an expression pedal which is set as a swell pedal will next to the volume also changes the timbre
of the stops. By this the effect of the swell box shutters of a pipe organ is simulated.
Crescendo pedal: The crescendo pedal can be used to activate 20 registrations step-by-step. These
registrations start with very quiet (pianissimo) to very loud (tutti).
If the crescendo pedal is not activated it is indicated on the displays with ‘Cr:--’.
Use the CR piston to activate the crescendo pedal. The display indicates the actual step.
Using the Johannus Menu, function 'Expression Pedals', the crescendo pedal can also be configured as
a swell pedal.
If the crescendo pedal is set as a swell pedal, all functions of the original crescendo pedal are
deactivated.
