You can also control the MPX R1 4-state relay in FX mode.
A relay is simply an electronic switch that can tell a circuit (typically an amp's
channel-switching scheme, or reverb and tremolo status) what "state" to go to.
Manufacturers use different schemes, or "logic states" to accomplish similar
tasks, and the MPX R1 can be programmed to satisfy these requirements,
allowing you, for example, to use your MPX R1 as a replacement for your amp's
channel-switching footswitch.
Storing a Relay State
The relay state can be stored with each MIDI Program Change message. To do
this, select the desired MIDI program on the MPX R1 and press the MPX R1 FX
button to enter FX mode
The relay states are assigned to the following buttons as factory defaults.
ON/OFF 1 = Relay state 1
ON/OFF 2 = Relay state 2
Press the button assigned to the desired relay state and hold the button down
for two seconds. The relay state (for example, CH1) will flash once on the MPX
R1 display to indicate that it has been stored with the program.
Clearing a Relay State
To clear a relay state, press and hold any button not assigned to a relay channel.
Hold this button down for two seconds until – – – flashes once on the display to
indicate the relay state for that program has been removed.
Removing Relay Settings for All Programs
To reset all of the relay settings to Not Assigned, go to Edit: Program Mode
(Press and hold the rear panel EDIT/RUN switch until Edt appears on the
display.) Use the BANK/Parameter Select buttons to select the Relay Initialize
parameter (rEi). Press Yes/+ to reset all of the relays. Note that the relays stay
in their last state (based on the last physical button press) until a button is
pressed to assign a different state. Briefly press and release the rear panel EDIT/
RUN switch to exit Edit Mode.
