6. TUNING THE INSTRUMENT
(TUNING menu)
Selecting the TUNING field on the main video page gives access to all the instrument’s tuning parameters.
o TRANSPOSER: transposer with a range of -6 to +5 semitones. When switched on, the organ’s
transposition is always zero.
o [second field on the display]: (Equal in the screen shown) selector for setting historical temperaments
of various periods and countries of origin.
o BASE KEY: the note on which the chain of 12 fifths that make up the temperament starts.
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 – (pipes perfectly tuned) to 8 (maximum pitch instability).
o AIR PRESSURE: simulates the drop in air pressure when a large quantity of air is requested in a short
time (e.g. when large chords are played with the Tutti). This is reflected in a temporary, gradual drop in
pitch, more evident in the longest, widest pipes (flutes, bourdons, principals).
o PITCH (A): fine tuning of the pitch, indicated as the frequency of A4 (an 8’ pipe).

NOTES
- When the instrument is switched on, its transposition value is set to zero
- Transposition does not have any effect on playback of pieces with the internal sequencer (unlike
recording, where the notes are acquired with the current transposition). A specific transposer
is provided for this purpose (see point 12.3).
o SUR (Surround): volume of the side speakers expands the sound stage, giving the feeling of being in a
bigger environment. Not present in the organs without side speakers.
o PRS (Presence): volume of the front side speakers makes the sound more natural and detailed, emphasizing
on the dynamic evolution of the pipes sound. Not present in the organs without additional front speakers.
o PHO (Phones): level of the output signal at the headphone [PHONES] connector underneath the manuals.
o EXT (External outputs): general volume of the PROG. OUT connectors on the rear panel.
o PED (Pedal): pedal board divisional volume.
o GRT (Great): Great divisional volume.
o SWL (Swell): Swell divisional volume.
o CHR (Choir): Choir divisional volume.
o SLO (Solo): Solo divisional volume.
o ORC (Orchestra): volume of the orchestra section. Not present in the models without orchestral voices.
Press [EXIT] or wait about 4 seconds to quit the screen and return to the previous video page.
