WHEELS
The wheels are performance devices which need to be practiced and mas-
tered, just like the keyboard. The Pitch wheel is on the left: the Mod wheel is
on the right.
Pitch Wheel and Pitch Wheel Range
The Pitch wheel allows you to play notes "between" the keys. This wheel is
double-sprung to automatically return to center. Near the center detent, you
may notice a "deadband" of insensitivity to make it easier for you to bend
"into" the note.
If you have played other synthesizers, you may already be in the habit of
checking the wheel positions each time you play. While this is a good habit
to get into, on the Prophet VS it is not strictly necessary. You do not have to
check the position of the Pitch wheel, because the springs return it to center
position.
Note: During "power-up," do not move the Pitch wheel. When the
computer is switched on, it assumes that the Pitch wheel is centered,
and takes the current position as the center pitch reference. So if you
move the Pitch wheel during power-up, you will be telling the computer
to take one of those o-center positions as center pitch, and everything
will therefore be detuned until you turn power o and then back on.
The Pitch wheel is monophonic. That is, it aects all the voices uniformly.
Except for latched arpeggiator notes, all voices are simultaneously pitch-bent
by the same interval.
Pitch Wheel Range adjusts the interval that will be played when the Pitch
wheel is rotated fully up or down. You can adjust the maximum range of the
Pitch wheel in one-semitone steps. The feel of the wheel is largely a matter
of personal taste. The wheel may bend notes up or down by as much as a
perfect fth (covering a range of fteen semitones). A narrower range gives
greater physical control over the bend. In other words, if you set the range
to the most "outside" bend you want to make, then you don't have to worry
about overshooting it.
Note: Like Master Tune, the Pitch Wheel Range adjustment is held
in non-volatile memory while power is o. Therefore when power is
switched on, Pitch Wheel Range will be however you last set it, so you
don't need to worry about it each time power is switched on.
To adjust the pitch wheel range:
1. Select Pitch Wheel Range parameter.
The display shows the current range in semitones, from one semitone
to a perfect fth.
2. To adjust the value, use the Data Entry slider.
