Program Sort, Search and Show

A DataBase function allows
you to sort the 250 MPX 1
preset and user programs
into various categories.
(When shipped, the MPX 1
is set to "Sort by Number".)

Tap

Many preset programs are
designed with their own
tempo rate settings. When­ever you see the Tempo
light flashing, simply press
Tap twice in rhythm to estab­lish the rate you want.

You can select other sorting
criteria in Program mode by
pressing Options. (The
Options LED will blink).
Use either the knob or the <
and > buttons to select:

Press Options again to re­turn to Program mode with
the DataBase sorted to
show only those programs
that fit the criteria you've
selected. The < and > but­tons will jump to the next
sorting category.

If the displayed program is
currently loaded, pressing
and holding Program will
display the effect routing as­signment.

Mix and Level

From any mode of opera­tion, press Mix. The button
will flash while Mix is active.

The display will show the
current mix and level set­tings. Use the < and > but­tons to select MstrMix, Mstr
Level, or to step to the Mix
and Level controls for any
active effect in the currently
running program. Use the
knob to adjust the flashing
parameter value. Press Mix
again to exit.

A/B

Many MPX 1 presets are de­signed with A/B patches that
allow you to morph between
two effects, glide rotary
speakers from slow to fast,
start and stop loop delays,
etc.

When A is lit, pressing the A/
B button activates a param­eter glide. Pressing A/B
again reverses the glide.

Store

Once you've made changes
to a program, press Store.
The Store LED will flash

while you change
the name of the pro­gram and decide
where to store it.

The lower line of the display
shows a user program num­ber (201-250) and the name
of the program currently
stored there.

The MPX 1 has 3 basic modes of operation, selected by
pressing: Program, Edit or System. This Quick Reference
Guide provides information only on the functions you can
access in Program mode. For complete details on other
features, read the MPX 1 User Guide.

sor between the program
number and the letters of the
current name on the upper
display line.

Turn the knob to select an­other program number, or
alphanumeric characters.
