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 

 

 

 

 

 

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 

 

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
