User Guide
Selecting the TUNING field on the main video page gives access to all the instrument's tuning parameters.
o TRANSPOSER: transposer with a range from -6 to +5 semitones. When switched on, the organ always
has transposition equal to zero.
o [second field on the display]: (Equal in the screen shown) selector for setting historic temperaments
of various periods and countries of origin.
o BASE KEY: the note on which the chain of the 12 fifths that make up the temperament starts.
o ENSEMBLE: level of natural tiny 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 obvious 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).
To quit the video page press [EXIT].
NOTE
Transposition does not have any effect on playback of pieces with the internal sequencer (unlike
recording, where the notes are acquired transposed). A specific transposer is provided for this
purpose (see point 12.3).
