ORGAN TUNING (Fine pitch adjustment of the instrument)
1
VALUE RANGE
From -100.0 cents (- 1 semitone) To + 100.0 cents (+1 semitone)
The intermediate position of 0.0 cents corresponds to the perfect tuning of the instrument, according to diapason
LA - 440 Hz.
With this control it is possible to fine-tune the pitch of the organ in relation to another musical instrument (or to
modify the diapason of an historical or programmable temperament).
ENSEMBLE (Ensemble effect of the stops)
2
With this control it is possible to increase or decrease the depth of the acoustic undulation among the various
stops, having previously done an adjustment using the control PITCH ADJUSTMENT. If the undulation ratio
between the stops is =0, the control ENSEMBLE will not work.
VALUE RANGE
From 1 (minimum undulation) To 8 (maximum undulation).
Insert (using the organ stops) a fairly rich stop, on the manuals as well as the pedal.
