About the MPX 110.........................................................................1-2
Highlights
Front Panel Overview ......................................................................1-4
Thank you for purchasing the MPX 110 Dual Channel
Processor, featuring Lexicon’s proprietary Lexichip®.
The MPX 110 is a true stereo, dual-channel processor
with 24-bit internal processing, analog-to-digital
conversion, and digital-to-analog conversion. It offers
240 presets with classic Lexicon reverbs, including Plate,
Chamber, Ambience, Tremolo, Rotary, Chorus, Flange,
Pitch, Detune, 5.7 second Delay, Echo, and Inverse.
Dual-channel processing creates two independent
effects in combinations such as Dual Stereo (Parallel),
Cascade, Mono Split, and Dual Mono.
The front panel Adjust knob allows instant manipulation
of critical preset parameters, and the Effects Lvl/Bal knob
controls effect level in SINGLE programs or effect
balance in DUAL programs. All programs can be selected
with the PROGRAM and VARIATION knobs. The
PROGRAM knob selects SINGLE, DUAL, or User
programs, while the VARIATION knob selects among 16
program variations.
Tap Tempo simplifies the once-complicated process of
matching delay times and modulation rates between
tempo-based presets and other music. Tempo-controlled
delays and modulation rates lock to Tap or MIDI clock. In
addition, Tap can be controlled using audio input, a dual
footswitch, the front panel Tap button, or an external
MIDI controller using MIDI Continuous Controller or
Program Change messages.
The MPX 110 features Learn Mode, a powerful editing
tool that allows MIDI patching of five front panel
controls. Standard Continuous Controller and Program
Change messages provide complete control over Bypass,
Effects Lvl/Bal, Mix, Tap, and even Adjust.

CONNECTING THE UNIT
The INPUT and OUTPUT connectors on the MPX 110 are
1/4 inch unbalanced sockets. Connections should be
made utilizing high-quality shielded cables with 1/4 inch
Tip/Sleeve phone plugs at the end connected to the unit.
The unit produces effects from either mono or stereo
sources. For mono sources, use the RIGHT (MONO)
INPUT. For instruments and stereo sources, use both
inputs. It is recommended to use stereo outputs
whenever stereo inputs are used. Use the RIGHT
(MONO) OUTPUT if mono output is required. The left
and right input signals are combined internally when
only the RIGHT (MONO) OUTPUT is used.
HEADPHONES
The LEFT (PHONES) OUTPUT supplies a stereo signal
adequate to drive headphones, provided no connections
are made at the RIGHT (MONO) OUTPUT. This feature is
included for convenience and practice purposes. It is
intended to provide modest volume.
FOOTSWITCH
A footswitch connected to the rear panel FOOTSWITCH
connector can be used to control front panel Tap and
Bypass functions. A momentary footswitch can be wired
to a Tip/Ring/Sleeve connector or a stereo Y-connector,
which allows two identical switches to be used.
Note:
Power off the unit prior to connecting the
footswitch. Otherwise, Bypass functions will be
enabled.
Dual-Function Footswitch
A dual-function footswitch with
labels to indicate Tap and Bypass
functions is available at Lexicon
dealers or www.lexicon.com.

SETTING AUDIO LEVELS
1. Begin with the Input knob set to the 9 o’clock
position.
2. Set the instrument or effects sends to a modest
output level.
3. Begin playing or sending audio to the MPX 110. The
Level LEDs should light green. If the Clip LEDs light
red, reduce the output level of the instrument or
effects sends until the Clip LEDs do not light during
the loudest passages.
4. Continue to play or send audio to the MPX 110.
Gradually increase the Input knob setting until the
Clip LEDs light red on the loudest passages.
5. Set the Mix knob to Dry.
6. Set the Output knob to the desired level.
7. If utilizing console sends and returns, set the Mix
knob to Wet. If utilizing an instrument amplifier, set
the Mix knob to the 12 o’clock position.
The Level LEDs do not light when the incoming signal is
more than 30dB below overload. The Clip LEDs light red
when the signal approaches overload (-2.5dB). When an
acceptable signal is present, the Level LEDs light green
almost continuously and the Clip LEDs flash red on the
loudest passages.
Note:
As with all audio products, it is good practice to first
power on all outboard equipment, then the mixer,
then the speakers.

REINITIALIZATION
The procedure below outlines the process to reinitialize
the unit. When reinitialized, the unit will restore all
System Mode parameters to their factory-default
settings; replace all User programs with factory-default
presets; and clear all Learned Patches.
To reinitialize the unit:
1. While powering the unit on, press and hold the front
panel Store button until the Store and Tap LEDs flash
quickly.
2. To reinitialize the unit, press the Store button. To
cancel reinitialization without affecting the unit,
press either the Tap or Bypass button.
3. After reinitialization, restart the unit - power it off,
then on again.
Note:
Reinitialization will cause the unit to:
•Restore all System Mode parameters to their
factory-default settings.
•Replace all User programs with factory-default
presets. (See the table on page 4-38.)
The Adjust knob has been customized for
each individual program, and in most
cases controls several parameters at once
to handle complicated editing processes.
For instance, Adjust controls the
“liveness” of space in many Chamber and
Room programs by changing decay, EQ, and early
reflections simultaneously.
The behavior of the Adjust knob is also customized for
different functions:
•It can act as a linear control, at its
minimum value when set to the 7
o’clock position and its maximum
value when set to the 5 o’clock
position.
•It can act as a bipolar control, at its
minimum value when set to the 12
o’clock position, like a cut/boost EQ
control.

SELECTING PROGRAMS
All programs can be selected with the front panel
PROGRAM and VARIATION knobs. The PROGRAM knob
selects either a SINGLE, DUAL, or User program. SINGLE
program selections are arranged around the left side of
the knob; DUAL and User program selections are
arranged around the right side of the knob. The
VARIATION knob selects among 16 program variations,
arranged around the knob.
SINGLE PROGRAMS
When the PROGRAM knob is set to a SINGLE program:
•VARIATION knob settings 1 to 8 will load eight
variations of the first effect.
•VARIATION knob settings 9 to 16 will load eight
+–
variations of the second effect.
MPX 110
Basic Operation
•See pages 4-2 to 4-17 for more information about
SINGLE programs.
For example, when Plate, Gate is selected:
•VARIATION knob settings 1 to 8 will load eight
different Plate program variations.
•VARIATION knob settings 9 to 16 will load eight
different Gate program variations.
When Special FX is selected:
•VARIATION knob settings 1 to 16 will each load one
program.
•See page 4-18 for more information.

contains both effects.
•See pages 4-20 to 4-35 for more information about
DUAL programs.
USER PROGRAMS
When the PROGRAM knob is set to User:
•VARIATION knob settings 1 to 16 will each load one
memory location available for storing User
programs. When shipped, these locations will
contain duplicates of presets.
•See page 4-38 for more information about User
programs.

EDITING PROGRAMS
The front panel Adjust and Effects Lvl/Bal knobs can both
be used to edit programs. The Adjust knob provides
instant manipulation of critical program parameters.
These parameters are arranged under the knob, meaning
that just one turn is all that is required to customize a
program to personal taste. The Effects Lvl/Bal knob can
be used to control effect level in SINGLE programs, or
effect balance in DUAL programs.
The unit recognizes changes made with either knob as
edits. When edits are made, the front panel Edit LED will
light to indicate that the selected program has been
modified but not stored.
Use the Adjust knob to edit the
selected program, and the Effects
Lvl/Bal knob to control effect level in
SINGLE programs or effect balance
in DUAL Programs. The Edit LED will
light to indicate that the selected
program has been modified from its
stored condition.
STORING PROGRAMS
To store a program in a User memory location:
1. Press the Store button. The Store LED will
flash slowly to indicate that the store
function is activated.
2. To continue saving the program, set the PROGRAM
knob to User. To cancel the store function without
saving the program, make sure the PROGRAM knob
is not set to User, then press the Store button again.
3. Set the VARIATION knob to select one of the 16 User
memory locations.
4. Press the Store button to save the program to the
selected location. The Store LED will flash quickly
until the store process is complete. The Edit LED will
no longer be lit when the saved version becomes the
selected program.

MPX 110
Basic Operation
CAUTION
When new programs are stored in a User memory
location, programs that were previously stored at that
location will be automatically replaced.
TAP TEMPO
VARYING RHYTHM
Tap Tempo can be used to match the delay
times and modulation rates of tempo-based
programs with those of the music. The Tap LED
will flash whenever a tempo-based preset is loaded. To
set tempo from the front panel, press the Tap button
twice in time with the music. It is not required to enter
what could be the delay time in milliseconds. Just press
the Tap button twice, and the unit will calculate the
appropriate delay time. To change tempo, press the Tap
button twice again in the new rhythm. Changes made to
tempo with the Tap button are not considered program
edits, and will not cause the Edit LED to light.
AUDIO TAP
To use audio input to set tempo:
1. Press and hold the Tap button for 2
seconds. (The optional dual footswitch
allows the musician to remain in contact
with the instrument while pressing and holding the
Tap button.)
2. While holding the Tap button, play two short notes
in rhythm, then release the Tap button. The unit will
automatically calculate tempo based on the time
lapse between the two notes.
Audio tap is a must for live performances. It offers a
simple method of setting delay times and modulation
rates to match the music.

BYPASS
The Bypass button can be used to mute audio
or to force the unit to pass only dry,
unprocessed audio. Its function depends on the
setting of the System Mode parameter Bypass. When set
to Bypass Dry, the unit sends only dry, unprocessed
audio to the outputs. When set to Mute Input, the unit
mutes the inputs only. Running effects will continue their
natural decay. Bypass functions can also be activated
with a footswitch or MIDI control device (see pages 1-8
and 5-5).
When pressed and held for 2 seconds, the Bypass button
also activates System Mode. (See Section 3 for more

PLATE
Plate reverb began with a large, thin sheet of metal
suspended upright under tension on springs.
Transducers attached to the plate transmitted a signal
that made the plate vibrate, causing sounds broadcast
through it to appear to be occurring in a large, open
space.
The Plate programs synthesize the sound of metal plates
with high initial diffusion and a relatively bright-colored
sound. These programs are designed to be heard as part
of the music, mellowing and thickening the sound. Plate
programs are a popular choice for enhancing pop music,
particularly percussion.

GATE
Gated reverbs were created by feeding a reverb, such as
a metal plate, through an analog gate device. Decay
time was set to instant, while hold time varied
duration and sound.
The Gate programs provide a fairly constant sound with
no decay until the reverb is cut off abruptly. These
programs work well on percussion, particularly on snare
and toms. It is recommended to experiment with other
sound sources as well.

CHAMBER
Historically, recording studio chambers were oddly
shaped rooms with a loudspeaker and set of
microphones to collect ambience in various parts of the
room.
Stereo Chamber programs produce even, relatively
dimensionless reverberation with little color change as
sound decays. The initial diffusion is similar to Hall
programs. However, the sense of size and space is much
less obvious. This characteristic, coupled with the low
color of the decay tail, makes these programs useful on
a wide range of material - especially the spoken voice, to
which Chamber programs add a noticeable increase in
loudness with low color.

AMBIENCE
Ambience adds warmth, spaciousness, and depth to a
performance without coloring its direct sound. It is
commonly used to add a room sound to recorded music
and speech. In music recording, Ambience can
realistically add distance to close-mic’ed signals.
Ambience programs simulate reflections from room
surfaces with random reflections, a gradual decay of
overall level, and a gradual narrowing of bandwidth. In
these programs, the Mix control adds depth - emulating
the movement of a coincident pair of microphones away
from the sound source into the room.

TREMOLO
Tremolo is a rhythmic change in loudness, commonly
employed as an expressive technique by vocalists and
wind instrument players. It is also one of the oldest
electronic effects, frequently used with electric guitar,
electric piano, and occasionally vocals. Different tremolo
effects are largely determined by the rate (fast or slow)
and waveform shape (smooth or sharp) of the change in
loudness. If the effect is used in a stereo mix, the left and
right can be synchronized to produce dramatic side-toside motion.
The Tremolo programs offer classic tremolo shapes, such
as square, sawtooth, triangle, sine, and rectified sine. The
synchronization of the left and right channels can be
adjusted to produce mono and stereo effects. The Tap
button sets tremolo rates, making it simple to match the
tempo of the music. The Adjust knob (phase) sets left
and right channel waveforms out-of-phase, resulting in a
panning motion.
Set the front panel Mix knob to Wet for all program
variations. Mix can be used to effectively set the depth of
the Tremolo program when more dry is added to the
wet-to-dry mix. (Turn the knob to the right, moving its
setting closer to Dry.) It is recommended to make the
rate work with the tempo of the music, as Tremolo is
essentially a rhythmic effect.
The Adjust knob can function as a fourposition switch, selecting the amount of
phase shift. When a setting is selected in the
0 range, no phase shift is applied. When a
setting is selected in the other ranges, the
indicated amount of phase shift is applied.
Numbers indicate phase shift in degrees.

ROTARY
Rotary speaker cabinets were designed to provide a
majestic vibrato/choir effect for electronic theater and
church organs. The most well known rotary speaker is
the Leslie™ Model 122, which has two counter-rotating
elements: a high-frequency horn and a low-frequency
rotor with slow and fast speeds. The sound generated as
the spinning elements change speed is truly magical.
The swirling, spacious effect is difficult to describe - but
clearly recognizable.
The Rotary programs are a detailed simulation of a
Leslie-style cabinet. The input signal is split into high and
low-frequency bands. The rotation effect is created by a
synchronized combination of pitch shifting, tremolo,
and panning. Like the physical cabinet, the high (horn)
and low (rotor) frequencies are “spun” in opposite
directions. Horn and rotor speeds are independent, and
designed with acceleration and deceleration
characteristics to simulate the inertia of the original
mechanical elements.
A virtual requirement for organ music, Rotary programs
also sound remarkable with guitar and electric piano
rhythm parts. In fact, these programs are great
alternatives to chorus and tremolo effects for any sound
source.
To achieve the full effect, set the front panel Mix knob to
Wet for all variations of this program (9 to 16).

CHORUS
Chorus effects create lush, full sounds by multiplying the
original audio source. Traditionally, these effects were
used to fatten up tracks and to add body to guitar
without coloring the original tone. Chorus effects are
also often combined with plates, echoes, and other
reverb effects.
The stereo Chorus programs, inherited from Lexicon’s
PCM 80, create a rich, airy effect that simulates the
sound of multiple sources from a single source. These
programs are stunning on acoustic or clean-electric
guitar.
These programs utilize six independently-randomized
delay voices panned across the stereo field. Set the front

FLANGE
Flange effects were originally created by simultaneously
recording and playing back two identical programs on
two tape recorders, then using hand pressure against the
flange of the tape reels to slow down first one machine,
then the other. The result was a series of changing phase
cancellations and reinforcements, with characteristic
swishing, tunneling, and fading sounds.
The stereo Flanger has two 2-Tap delays - one per
channel. The first tap is fixed, and the second sweeps
past it. Mixing the two delay taps together creates the
flanging effect.

DELAY, ECHO
Delays and echoes repeat a sound a short time after it
first occurs. The simplest (and oldest) delay effect is tape
slap - a single repeat about 100ms after the original
sound. Tape slap was often used on Elvis Presley’s voice
and rockabilly guitar tracks.
Tape slap becomes tape echo when the output of the
tape is fed back into the input (feedback). This turns a
single repeat into a series of repeats, each a little softer
and a little darker than the last. This darkening is
characteristic of the analog tape recording process.
Digital delays do not have this characteristic; each repeat
has the same exact timbre. For digital delays, loudness is
the only difference from repeat to repeat.
Tape echo and digital delay are both useful, but
different. Tape echo is warmer, allowing the original
sound to distinguish itself. Digital delay presents a
“perfect” copy of the original sound.
The Delay and Echo variations include mono (5.5
seconds), stereo (2.7 seconds), and 6-voice multi-tap
effects. Each program can be used for tape echo or
digital delay effects.
When the Adjust knob is set to a
MIN
value between 12 and 5 o’clock,
tape echo effects are produced. Each
Delays
Echoes
repeat is darker and softer. When the
Adjust knob is set to a value between
MAX
MAX
7 and 12 o’clock, digital delay effects are produced. Each
repeat is the same timbre, but softer.
In variations 1 to 8, the Adjust knob sets the amount of
feedback with an increasing number of repeats as the
setting is increased. Delay time is set with Tap. Each
program is preset with a different rhythm. In
variations 9 to 16, the amount of feedback is preset and
the Adjust knob determines the delay time.
With all Delay and Echo effects, note the way the repeats
fall rhythmically to the beat. The most effective Delay
and Echo patterns are those that lock with the tempo of
the music.

DUAL PROGRAMS
The DUAL Programs combine Delay with Reverb, or

Four routing configurations are used in the variations of
each DUAL program: Dual Stereo (Parallel), Cascade,
Mono Split, and Dual Mono.
Variation knob settings are configured as follows:
•Variations 1 to 6 are arranged in the Dual Stereo
(Parallel) configuration - two stereo effects placed
next to one another to receive and output stereo
audio from both the left and right channels.
•Variations 7 to 10 are arranged in the Cascade
configuration - two stereo effects, one placed after
the other. For example, in Flange-Delay, Flange
passes its stereo signal to Delay.
•Variations 11 to 14 are arranged in the Mono Split
configuration, which is similar to the Dual Stereo
(Parallel) configuration. One effect (Flange) receives
audio from the left input and the other effect (Delay)
receives audio from the right input. Both effects
output stereo audio.
•Variations 15 and 16 are arranged in the Dual Mono
configuration where one effect (Flange) appears on
the left channel only, while the other effect (Delay)
appears on the right channel only.

THE PITCH PROGRAMS
The MPX 110 features single Pitch, Pitch-Delay, and
Pitch-Reverb programs. All pitch programs are designed
to input and output two channels and to respond to
pitch-shifting in either Stereo or Dual Mono mode.
Note:
In this case, Dual Mono refers to signal type - not
routing configuration.
In Stereo mode, the same pitch-shift is applied to both
channels at the same time. This helps maintain the
proper phase relationship between the channels. When
pitch programs operate in Stereo mode, rotating the
Adjust knob will affect both channels in the same
manner.
In Dual Mono mode, pitch-shift is applied to each
channel separately. When pitch programs operate in
Dual Mono mode, rotating the Adjust knob will affect
each channel in a different manner. Sometimes one
channel may seem to experience no effect at all.
The mode in which a particular program responds to
pitch-shifting cannot be selected. The tables that begin
below list each pitch program along with its assigned
mode of operation.

USER PROGRAMS
When the PROGRAM knob is set to User, VARIATION
knob settings 1 to 16 each select one memory location
available for storing User programs. When shipped, these
locations will contain duplicates of preset programs. The
table at the right lists the factory-default preset stored in
each User memory location.
Learn Mode enables the MPX 110 to “learn” MIDI Program Change and
Continuous Controller messages. To activate and deactivate Learn Mode, press
the Store and Tap buttons simultaneously. The Store LED will flash slowly and the
Tap LED will light to indicate that Learn Mode is active.
The unit supports five learned patches for the front panel Mix, Effects Lvl/Bal,
Adjust, Bypass, and Tap controls. Program Change messages 0 to 15 are reserved
for executing program loads. The Program Load function can also be assigned to
a separate MIDI channel (see page 5-3).
These controls can be
patched to Continuous
Controller messages.
These controls can also
be patched to Program
Change messages.
Program Change messages can
be used to load programs.
Simultaneously press the
Store and Tap buttons to
activate and deactivate
Learn Mode.

MPX 110
MIDI Operation
PROGRAM LOAD CHANNEL
The MPX 110 is designed to have one MIDI channel
dedicated to loading programs, called the Program Load
MIDI Channel. This allows Program Change messages to
load programs.
The Program Load channel can be the same channel that
is used to receive other Program Change messages for
Learned Patches. However, numbers 0 to 15 will always
load the 16 variations of the selected program. Program
Change messages 0 to 15 will be ignored on all other
MIDI channels.
MIDI channel 1 is the default Program Load Channel. To
assign this function to a different channel:
1. Simultaneously press the Store and Tap buttons
to activate Learn Mode. The Store LED will flash
slowly and the Tap LED will light to indicate that
Learn Mode is active.
2. Send a Program Change message to the unit. The
Edit LED will flash to indicate incoming MIDI activity.
3. The unit learns the MIDI channel of the transmitting
device, and reassigns the Program Load function to
that channel.
4. Simultaneously press the Store and Tap buttons
to deactivate Learn Mode.
The unit will remember the Program Load Channel
assignment until the Program Load Channel is
reassigned using the same procedure.

PROGRAM CHANGE MESSAGES
LOADING PROGRAMS
Standard MIDI Program Change messages can be used
to load all 240 preset and 16 User programs. The unit
conforms to the use of MIDI Continuous Controller 32 to
execute Bank Select messages. For purposes of this
section, each PROGRAM knob setting selects a “bank” of
16 programs. These banks are numbered as shown in the
table at the right.
When a standard MIDI Program Change message is sent
to the unit on its Program Load channel, Program
Change messages 0 to 15 will load program variations 1
to 16 from the selected program bank. When a Bank
Select message is sent to the unit with Continuous
Controller 32 before the Program Change message, any
one of the 256 programs can be loaded.
For example, the PROGRAM knob is set to Plate, Gate:
•Sending Program Change 1 will load the first Plate
program.

programs within that bank until a new value for
Controller 32 is received, or until the PROGRAM or
VARIATION knobs are adjusted.
MIDI Program Change messages can be disabled in
System Mode with the MIDI Pgm Change parameter
(see page 3-4 for more information).
ACTIVATING BYPASS OR TAP FUNCTIONS
The unit can recognize MIDI Program Change messages
16 to 127 (17 to 128 on some MIDI devices) on any
channels.
To assign a Program Change message to the Bypass or
Tap controls:
1. Simultaneously press the Store and Tap buttons
to activate Learn mode. The Store LED will flash
slowly and the Tap LED will light to indicate that
Learn Mode is active.
2. Press the desired front panel button - Bypass or Tap.
3. Send a MIDI Program Change message to the MPX
110. The Edit LED will flash to indicate incoming
MIDI activity.
4. Press the Store button to commit the assignment.
The Store LED will flash repeatedly.
5. Simultaneously press the Store and Tap buttons
to deactivate Learn Mode.
Some MIDI controllers do not allow repeated Program
Change messages to be sent with a single button. To
assist these controllers, the unit also recognizes the next
highest Program Change message with each Program
Change message it learns for Bypass and Tap. For
instance, if Program Change 20 is learned as the source
for Bypass, Program Change 21 will also control Bypass
functions. To avoid conflicting Bypass and Tap
assignments, leave a space between the assignments of
these two buttons. For instance, if Program Change 20 is
learned for Bypass, remember that 21 will also be
learned. Skip to Program Change 22 (and consequently
23) for Tap.

LEARNING CONTINUOUS CONTROLLERS
The unit recognizes Pitch Bend, AfterTouch, and MIDI
Continuous Controllers 1 to 31 and 33 to 119.
To learn a Continuous Controller:
1. Simultaneously press the Store and Tap buttons
to activate Learn mode. The Store LED will flash
slowly and the Tap LED will light to indicate that
Learn Mode is active.
2. Adjust the desired front panel control - Mix, Effects
Lvl/Bal, Adjust, Bypass, or Tap - to assign it to the
controller.
3. Move the MIDI controller through its full range. To
utilize a portion of the controller range, limit this
movement to the desired range. The Edit LED will
flash to indicate incoming MIDI activity.
4. Press the Store button to commit to the assignment.
The Store LED will flash quickly.
5. To assign another front panel control, repeat steps 2
to 4.
6. Simultaneously press the Store and Tap buttons
to deactivate Learn Mode.
Note:
When a MIDI controller has been assigned to the
Bypass control, moving the controller above the
mid-point of its learned range engages Bypass.
Moving the controller below the mid-point range
disengages Bypass. When a MIDI controller has
been assigned to the Tap control, moving the
controller above the mid-point of its learned range
will “tap” the control as if the Tap button had been
pressed.

MIDI CLOCK
The unit can use MIDI Clock messages to apply tempo
(40 to 400bpm) to programs that use the Tap Tempo
feature. Connect a MIDI device that outputs MIDI Clock,
such as the MPX R1 foot controller or a MIDI sequencer,
to the MPX 110 MIDI IN connector. The unit will
automatically recognize and begin to process MIDI Clock
messages. When the tempo of the connected device
changes, the unit will automatically adjust its delay times
and modulation rates to match the new tempo.
This feature can be disabled with the MIDI Clock Receive
parameter in System Mode (see page 3-5).
MIDI DUMPS
MIDI Dumps can be used to save the 16 User programs,
the currently active program, or the System Mode
settings and Learned Patch assignments to a storage
device (typically a MIDI sequencer). MIDI Dumps are
performed in System Mode.
To perform a MIDI Dump:
1. Press and hold the Bypass button for 2 seconds. The
Bypass and Store LEDs will blink to indicate that
System Mode is active.
2. Set the VARIATION knob to 14 to dump the User
programs; 15 to dump the currently active (or
loaded) program; or 16 to dump the System Mode
settings and Learned Patch assignments.
3. Press Store to execute the dump.
4. Press Bypass to deactivate System Mode.

MIDI SYSEX MESSAGES
MIDI Sysex messages can be used to access all algorithm
parameters. More information about using this advanced
feature with the MPX 110 and other Lexicon products is
available at www.lexicon.com. The website offers
instructions, sample messages, and a complete table of
parameter Sysex addresses.
Note:
Executing MIDI Sysex messages is a complicated
process. Please observe the cautionary notes
included on the website.
PERMANENT PATCHES
The MPX 110 recognizes permanent, non-learnable
MIDI patches to provide additional MIDI control.
Permanent patches connect designated Continuous
Controllers to specific audio parameters that are not
accessible on the front panel. Permanent Patches for
each algorithm are shown on pages 5-10 and 5-11.
The unit recognizes Permanent Patches on the current
Program Load Channel only. To use a permanently
patched controller for a Learned Patch, make the unit
learn that patch on a different channel. If a controller is
used for both a Permanent and Learned Patch on the
same channel, the result will be unpredictable.
Some patched parameters are also controlled with the
Adjust knob. In these cases, either control will function
and will override adjustments made by the other.
Note:
Permanent Patches will be disabled when the System
Mode parameter MIDI Patching is set to Disabled.
