Multi-effect control
(MFX Control Screen)
If you want to use an external MIDI device to control multi-effect
parameters such as the volume or delay time of the effect, you would
normally need to transmit device-specific types of MIDI messages
called ”system exclusive” messages. However, system exclusive
messages involve complex settings, and require a larger amount of
data to be transmitted.
For this reason, the ARX-03 expansion board lets you use
conventional MIDI messages, such as control change messages, to
control some of the important multi-effect parameters. For example,
you could use the pitch bend lever to change the amount of
distortion, or use keyboard touch to change the delay time. The
parameters that can be controlled in this way are pre-specified for
each multi-effect type. For each multi-effect type, such parameters
are indicated by a ”#” symbol in the ”Multi-effect parameters” list (p.
42).
Multi-effect control refers to this capability of using MIDI messages to
control multi-effect parameters in real time. The ARX-03 expansion
board lets you use four multi-effect control settings simultaneously.
To use multi-effect control, you need to specify which MIDI source
(Source 1–4) will be controlled by which parameter (Control Assign
1–4), and to what extent (Sens 1–4).
MFX Control Sens 1–4
MFX Control Source 1–4
Value
Description
-63–+63
Specifies the depth of multi-effect control.
Select a positive (+) value if you want to modify the
parameter in the positive direction (higher value, toward
the right, faster, etc.) relative to its current setting. Select
a negative (-) value if you want to modify the parameter
in the negative direction (lower value, toward the left,
slower, etc.) relative to its current setting. For either ”+”
or ”-” settings, larger values will allow a greater range of
control. Select ”0” if you don’t want to modify the
parameter.
