Fx Mode; Relay State Programming - Lexicon MPX R1 User Manual

FX Mode allows you to turn on and off any of the active effects in the current
program. To access FX Mode, press the MPX R1 FX button. The LED next to
the button will light to indicate you are in FX Mode.
Buttons 1, 2, 3, 6, 7 and 8 bring MPX 1 effects (Pitch, Chorus, Delay, Reverb,
EQ and Mod) in and out of bypass. The LED for each button indicates the current
state of the MPX 1 Effect:
Green = MPX 1 Effect on
Red = MPX 1 Effect bypassed, but available
Off = MPX 1 Effect unavailable
As in Program mode, the R1 will update to match the current MPX 1 A/B, Tempo
and Bypass states of the currently loaded program. If you press any of these
controls on the MPX 1, or if you load a new program from the MPX 1, the R1 will
update accordingly.
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 relacement 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
ON/OFF 3 = Relay state 3
ON/OFF 4 = Relay state 4
The FX LED is lit when FX Mode
is active.
