Editing
Each MPX 500 program has as many as 16 editable parameters, organized into edit "pages" of as
many as four parameters each. The front panel Edit Pages button cycles through all of the available
pages for the current program.
Dedicated edit knobs corresponding to each page of displayed parameters make program adjustment
easy. Simply turn the knob (1-4) for the displayed parameter (1-4) you want to adjust. When you alter
a parameter value, it will be highlighted and the Edited LED will light to show that the program is
different than the currently running version. (These edit indicators will be turned off when you store
the new program, or if you load another program.) If you return to Program Select mode without storing
your changes, your edited version will still appear as the currently running program, but the Load LED
will light and the original version of the program will be cued.
The 4 front panel edit knobs correspond to the
displayed parameters. Position 1 on Page 1 always
contains a special custom control for easy editing.
Edited parameter values will be highlighted.
Pressing Edit Pages will display
another page of parameters.
The Edited LED will light to
show that the program has
been changed from the
currently running version.
The current tempo will be
displayed (in BPM) if the
program contains tempo-
based parameters.
