Viscount Physis OrgansReference Manual
the display shows the organ’s sections, allowing selection of the one containing the voice to be modified:
after which the voice the parameters of which are to be viewed can be displayed.
Another way of viewing the setting screen directly is to hold out the draw-stop or hold down the rocker tab
(except in the models with electromechanical draw-stops) for a few moments in the voice on position
with the cursor on the EDIT PARAMETERS field in the VOICES menu, or in the function itself.
The LED of the stop being modified will flash to prevent modification errors; the stop will be on and can be
played for better, quicker adjustment. Other stops can also be switched on to assess the overall effect of the
changes.
The parameters displayed are not the same for every voice, since some families have specific setting parameters
not required for other types of voice.
The settings which can be made are:
o CHARACTER: harmonic richness.
o AIR NOISE: noise of the air blowing through the pipe.
o REED NOISE: imperfect synchronisation of the reed throb period.
o ATTACK: attack time the sound takes to reach the maximum volume.
o REL. DETUNE: (Release Detune) detuning in the release phase.
o FREQ. SKEW: gradual change in the air’s pitch during the attack and release phases.
o DETUNE: detuning to produce the throb effect in the voices concerned.
o DETUNE TYPE: Select one of the three types of beating:
- A: the beat frequency is almost constant over the entire range of the keyboard;
- B: the beat frequency increases moderately proceeding towards the top of the keyboard;
- C: the beat frequency increases significantly progressing towards the upper part of the keyboard.
o KEYB. LO LEV.: (Keyboard Low Level) gain (positive values) or attenuation (negative values) of the
volume in the low part of the manual.
o KEYB. LO LEV.: (Keyboard High Level) gain (positive values) or attenuation (negative values) of the
volume in the high part of the manual.
o TREMOLO: select the first (1st) or second (2nd) tremolo. The selected tremolo will be applied to the
register when activated through the dedicated stop or draw-stop (see also chap. 9.1).
To quit the function and save the values press [EXIT].
