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 three times 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 three times 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.
When you load a new program, it takes about 100 milliseconds for the MPX 1
to fade out the old program and then fade in the new program. (That's about a
16th note at 120 BPM.) For most musical situations that's plenty of time. For
those situations where you really need to "nail" a sound change, you can be
more precise by using the individual effect bypass buttons (in FX Mode) to
instantly turn individual effects on or off.
For example, at the beginning of a tune, load a preset (using Program or Direct
Access Mode) with the effects you want — say, Chorus, Delay and Reverb.
Then, while you're playing, turn the desired effects on and off from FX Mode via
the MPX R1 effect buttons.
First, connect the Effects Loop Send(s) to the MPX 1 Input(s).
If the Effects Loop send has two outputs (L, R):
connect them to the left and right inputs of the MPX 1. On the MPX 1,
press System, select Input Mode and set it to Stereo.
If the Effects Loop has only one output:
connect it to the left input of the MPX 1. On the MPX 1, press System,
select Audio: Input Mode and set it to Mono(L only).
Connect the MPX 1 Output(s) to the amp's Effects Loop Return(s)
If the Effects Loop has left and right return inputs:
connect them to the left and right outputs of the MPX 1.
If the Effects loop has only a single return input:
connect it to the left output of the MPX 1. (Effects will be richer if both
outputs can be used, but MPX 1 V1.10 presets (100 through 159) have
been optimized for use with only one output connected.
