5. VOICE PROGRAMMING
5.1 PARAMETERS INVOLVED
One of the most interesting features of the Prestige is that the user is able to modify each individual voice or register of the
organ by altering a number of its main parameters.
The modified voice is maintained even with the instrument switched off, and it can also be saved on floppy disk and
reloaded as necessary.
The following is a list of the parameters used for voice modification, and the relative descriptions:
1.
LEVEL parameter (abbreviated to Lvl): This is the parameter which regulates the general level of the voice. The
maximum range of this parameter -8/+7 corresponds to -/+4 Db.
2. Section
KEYBOARD VOLUME TRACKING parameter: The volume tracking parameter allows a different
volume ratio to be assigned to the voice depending on whether it is played in the high or low part of the manual.
The Prestige VII therefore provides the user with two parameters, called TRACKING LOW (abbreviated to Trl)
and TRACKING HIGH (abbreviated to Trh) which will define the relative volume of the voice for the low
section of the (Trl) and for the high section of the keyboard (Trh) respectively. The range for both parameters is -
8/+7, corresponding to -/+4 Db.
3.
RANK FLUCTUATION parameter (abbreviated to Rnk): When enabled, this parameter creates slight
fluctuations in timbre.
4.
PITCH ADJUST parameter (abbreviated to Pch): Regulates the fine tuning of the selected voice; the range of this
parameter is -8/+7, corresponding to
±
32/100 of a semitone.
5.
OUTPUT parameter (abbreviated to Out): Allocation of the voice output to the stereophonic panorama of the
organ, with the following possibilities:
- L (Left): The voice is addressed to the left-hand channel only.
-
R (Right): The voice is addressed to the right-hand channel only.
-
C/L (C to the Left): Starting from the note C of the first octave, which is addressed to the right-hand channel, all
the following notes in the chromatic scale will be addressed to each channel alternately (C-> right, C#-> left, D->
right, etc.).
-
C/R (C to the Right): Starting from the note C of the first octave, which is addressed to the left-hand channel, all
the following notes in the chromatic scale will be addressed to each channel alternately (C-> left, C#-> right, D->
left, etc.).
-
Mid (Left - Right): The voice is addressed in stereophonic panorama to the right and left-hand channels.
6.
COLOUR parameter (abbreviated to Col): Regulates the colour of the voice, meaning the ratio between its bass
and treble components (display range -8/+7).
7.
ATTACK CHIFF parameter (abbreviated to Atk): Regulates the attack speed of the voice in a scale of 16
different values (1 - 16) ranging from a minimum of about 2 msec. to a maximum of 300 msec. Note that the
parameter considers the time tracking of the manual and thus the maximum value of 300 msec. applies to the
central part of the manual, while it will be significantly higher for the lower part (about 500 msec.) and lower for
the high part (100 msec.).
8.
DETUNE RELEASE parameter (Rel): Regulates the variation in tuning on release of the key with maximum
range 50 cents of a semitone (equivalent to the range 1 to 16 on the display).
9.
RANDOM DETUNE (Rnd): This parameter allows regulation of the random variations in tuning between one
key and another of the manual, thus generating the chorus effect typical of a pipe organ (display range from 1 to
16).
N.B: For better listening the changes made by the parameters RANK FLUCTUATION and RANDOM DETUNE, we
suggest you to play two registers while modifying one’s parameters.
