3 Rane MPE Users Guide
User Modes and Functions
The MPE user interface is organized into three
main user modes. These are:
Normal Operating mode
EQ Edit mode
Expression Edit mode
Each user mode can be thought of as a drawer
containing a particular set of MPE parameters. To
adjust an MPE parameter, you enter the correspond-
ing mode (i.e., open the drawer), change the param-
eter, and then exit (close the drawer) when you’re
done.
As implied by its name, the Normal Operating
mode is the mode in which you normally operate the
MPE. Normal Operating mode is entered by the
MPE on power up, and is the mode from which you
enter the EQ Edit and Expression Edit modes. When
you exit either of these latter two modes, you are
returned to Normal Operating mode. Normal Operat-
ing mode could also be thought of as “Memory”
mode, since it is the mode in which you recall Stored
Memories, save them, recall Factory Presets, etc. We
will continue to call it Normal Operating mode.
Within the Normal Operating mode, there are 6
equalizer user functions :
Recall a Stored Memory
Store Working Memory
Recall Factory Preset
Set Ramp Step Size
Curve Weighting
Set Lockout Status
and 8 MIDI user functions:
Set MIDI Channel
Program MIDI Map
Enable OMNI Mode
Enable Program Change Output
Enable Key Scan Echo
Enable Parameter Echo
Set Device ID
Dump Memory
The EQ Edit and Expression Edit modes provide
the environments for you to edit the equalizer and
expression parameters, respectively.
The EQ Edit mode provides two user functions in
addition to the equalizer editing interface:
Compare
Clear (set to 0dB) Bands
Expression Edit mode provides a simple interface
to the expression parameters.
User functions must be accessed from the correct
mode. This is the most important concept for intui-
tive operation of the MPE. For example, if you want
to flatten the equalizer bands, you must be in the EQ
Edit mode to access this function. Similarly, you
must be in the Normal Operating mode to recall a
Stored Memory, set a MIDI parameter, and so on. If
you attempt to access a user function from the wrong
mode, the MPE hurls error messages into in the
SYSTEM display.
Entering user modes and functions is accom-
plished by pressing the key assigned to them. Each
key is identified on the front panel. You never have
to search through a hierarchy of hidden menus to
find them. (You’re welcome.)
You can usually enter the Normal Operating mode
simply by pressing the MEMORY key. The word
usually is stressed because there are two exceptions.
In EQ Edit mode you must press the EQ key until
the EQ LEDs are off to reach Normal Operating
mode (since the MEMORY key is used for the
compare function). In the Program MIDI Map
function you might have to press the MEMORY
key twice.
Entering EQ Edit mode is no big deal. Just hit the
EQ key. That’s it. Entering the Expression Edit
mode is just as easy, press the EXPRESS key.
So how can you tell which user mode you’re
currently in? If you’re in the Normal Operating
mode, the SYSTEM display area on the right side of
the MPE front panel will look something like:
