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.

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.

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
information about System Mode.)

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.

effects. Each program can be used for tape echo or
digital delay effects.

When the Adjust knob is set to a
value between 12 and 5 o’clock,
tape echo effects are produced. Each
repeat is darker and softer. When the
Adjust knob is set to a value between
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.

• 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.

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.

• Sending Controller 32 with a value of 0 followed by
Program Change 1 will load the first program in the
User bank.

• Sending Controller 32 with a value of 1 followed by
Program Change 2 will load the second program in
the Flange-Delay bank.

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.

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 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 Operation

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.
