EDIT-MIDI/CTRL
Knob 4
[ Turn] Range
Determines the range over which the specified function
will be controlled by data from an external MIDI controller
on the internal Program LFO.
[Range] -63 — +63
When set to "0" no controler variation will be
applied. The higher the value, the greater the
controller range. Negative values reverse the
operation of the controller.
[ Press] QUICK...
Calls the quick entry menu (page 83).
Knob 5
[ Turn] Type
The setting determines how the A5000/A4000 converts
and applies the control-change value received from the
controller.
When you move a controller at a MIDI device, the control-
ler transmits a control-change value indicating the magni-
tude of the movement. The transmitted values always
range from 0 to 127.
Upon receiving the value, the A5000/A4000 converts it as
specified here, and then applies it to the parameter
selected by the Function entry. The conversion deter-
mines how strongly (and in which direction) the parame-
ter changes in response to the controller's movement.
[Range] +offset, -/+offset, +offset(-exp), +offset(+exp)
• +offset ... The A5000/A4000 converts the received
value (0 to 127) to a corresponding value in
the range {0 to range}, and adds the result to
the target parameter. Notice that the resulting
offset is therefore always positive (or always
negative, depending on the Range sign). In
other words, the controller can offset the tar-
get parameter in one direction only.
• +offset ... The A5000/A4000 converts the received
value (0 to 127) to a corresponding value in
the range {-range to 0 to +range}, and adds
the result to the target parameter. Notice that
in this case the controller applies 0 offset
when at its center position; displacement in
one direction generates a negative offset,
while displacement in the other generates a
positive offset.
• +offset(-exp) ... The received value (0 to 127) is
converted to an appropriate value within the
available range. The conversion is not linear,
however, with greater variation produced at
lower values and less variation produced at
higher values.
• +offset(+exp) ... The received value (0 to 127) is
converted to an appropriate value within the
available range. The conversion is not linear,
however, with smaller variation produced at
lower values and greater variation produced at
higher values.
