The small parameter numbers in parentheses apply in the VL-XG sound module mode.
Pitch Bend
01
(01)
: PB Ctrl
• Pitch Bend Control
• Settings: -24 … +24
This parameter sets the maximum amount of pitch
bend which will occur when the pitch controller is
set to its maximum position (e.g. when the pitch
bend wheel on a keyboard is rolled all the way up).
Minus setting produce a downward pitch bend.
Each increment corresponds to a semitone. A
setting of “+12”, for example, results in maximum
upward pitch bend of one octave.
This setting automaically switches the plus/
minus status of the “PB LowCtrl” parameter,
below: If “PB Ctrl” is set to a “+” value, “PB
LowCtrl” is automatically switched to a “-”
value, and vice-versa.
Natural acoustic musical instruments have no
“pitch parameter”. Pitch is determined by the
properties of the instrument’s resonant body as
well as the condition of the instrument’s driver.
The same applies to Virtual Acoustic Synthesis:
in the VL70-m pitch bend is simulated by
manipulating the appropriate pipe/string length
and driver characteristics. As a result, the pitch
bend range may not always be “mathemati-
cally” accurate.
02
(02)
: PB LowCtrl
• Pitch Bend Low Control
• Settings: -24 … +24
“PB LowCtrl” sets the maximum amount of pitch
bend which will occur when the pitch controller is
set to its lowest position (e.g. when the pitch bend
wheel on a keyboard is rolled all the way down).
Plus settings produce an upward pitch bend. Each
increment corresponds to a semitone. A setting of
“-12”, for example, results in maximum downward
pitch bend of one octave.
03
(03)
: PBLFO PMod
• Pitch Bend LFO Pitch Modulation
• Settings: 000 … 127
Sets the amount of LFO pitch modulation applied
by the pitch controller (e.g. the pitch bend wheel
on a keyboard). The higher the value the greater
the amount of pitch modulation produced by pitch
controller operation. A setting of “000” produces
no pitch modulation.
In the VL70-m pitch modulation produces
extremely realistic vibrato effects by simulta-
neously modulating the pitch, embouchure, and
pressure parameters.
