Below is the list of editable Backpage parameters.
Expression Pedal Depth (XD)
The ' ' parameter can be used to modify the range or depth of an
XD
expression pedal connected to the
eters assignable to the expression pedal input will sound best when the
depth is not set to its maximum range.
- A single light in the +12 position denotes the maximum
depth of positive value.
- A single light in the -12 position denotes the maximum
depth of negative value.
- A single light in the '0' position is a neutral selection that
effectively disables the expression input.
Expression Pedal Control (XC)
The ' ' parameter can be used to select the input destination of an
XC
expression pedal or the
Sweep Range, Speed, and Mix) may be a destination. Filter modulation
and the effect selector knob are also available destinations.
When controlling a knob parameter, the knobs remain active with the
expression pedal signal summed with the knob position. This sum value
is pinned to stay within the full control range of the knobs alone. To
enable control of the entire range of a knob with an expression pedal,
it is important to set the destination knob to the full counter-clockwise
position. Otherwise, the value will pin and some of the range of the
expression pedal will not have any effect.
It is important to note that the signal from the expression pedal is
identical to the action of turning each knob. The range and direction
of the expression pedal is dictated by the '
set to a parameter above the neutral '
the expression pedal forward will be like turning the destination knob
clockwise. When '
(towards - ), moving the expression pedal forward will be like turning
12
the destination knob counter-clockwise.
