Channels
The “momentary, normally closed” state of a channel is Channel 4. Pressing a
channel button causes the relay to momentarily change to that channel’s state
and then change back to Channel 4. (Pressing a button assigned to Channel 4
does nothing.)
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.
Press the MPX R1 FX button to enter FX mode.
In the MPX R1 the relay states are assigned to the following buttons as factory
defaults.
ON/OFF 1
= Relay state 1
ON/OFF 2
= Relay state 2
ON/OFF 3
= Relay state 3
ON/OFF 4
= Relay state 4
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 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 – – – is flashed on the display to
indicate the relay state for that program has been removed.
Latching
To assign the relay using tip or ring when the relays are set to latching mode:
Assign the relay state to the desired button. This button will now have two relay
states: State 1 (Green) and State 2 (Off).
Follow the same method for assigning the relay as above. To save the CH1 relay
state, the button must first be put in CH2 relay. Then, when you press and hold
this button it will toggle the to the CH1 relay state.
Momentary
If the relays are set to momentary, normally closed, or to momentary, normally
open, you can store a momentary change on either the tip or the ring relay.
To reset all of the relay settings to Not Assigned, go to Edit: Program mode and
select the Relay Initialize parameter (rEi). Press Yes to reset all of the relays.
Note that the relays will stay in their last state (based on the last physical button
press) until a button is pressed to assign a different state.
