In the Effects/MFX screen you can set the parameters of the multi-
effect.
In this screen you can edit the parameters of the multi-effect you
selected in
“MFX Type” (p. 29). For details on the parameters that
can be edited, refer to “Multi-Effects List” (p. 34).
For details on Control Assign 1–4, refer to “ “Multi-effect control
(Effects/MFX Ctrl screen)” (p. 29).
Multi-effect control
(Effects/MFX Ctrl screen)
In order to control parameters such as the volume of the multi-effect
or the delay time of a delay from an external MIDI device, you will
normally need to transmit “MIDI system exclusive messages,” which
are a type of MIDI message that is specific to a particular device.
However, system exclusive message settings are complex, and these
messages will also increase the amount of data that needs to be
transmitted.
Thus, this expansion board allows you to use MIDI messages such as
control changes to control the most important multi-effect parameters.
For example, you can use the pitch bend lever to vary the depth of
distortion, or use your keyboard playing touch to change the delay
time. The parameters that can be controlled in this way are pre-
assigned for each multi-effect type. The parameters that are assigned
for each multi-effect type are marked with a “#” in the list of
“Multi-
Effects Parameters” (p. 35).
This ability to use MIDI messages to vary the multi-effect parameters
in real time is called “multi-effect control.” The ARX-01 expansion
board allows you to use four multi-effect controls simultaneously.
To use multi-effect control, you need to specify the MIDI message
(Source 1–4) that will control the desired parameter (Control Assign
1–4) in the specified way (Sens 1–4).

Multi-effect control lets you use
MIDI messages to control the pa-
rameters of the multi-effect. For de-
tails, refer to
