Turning Omni Mode On And Off
Sometimes it is necessary to instruct the MPE to
listen to all MIDI channels, but to only transmit on
one particular channel. This is useful, for example, if
you want the MPE to listen to another MIDI device
but don’t know what channel the device is transmit-
ting on. It is also useful when more than one MIDI
device is speaking to the MPE, and each is assigned
to a different MIDI channel.
Omni mode forces the MPE to accept messages on
all MIDI channels. The MIDI channel assigned to
the MPE is still attached to transmitted messages.
To place the MPE in Omni mode, or take it out of
Omni mode, perform the following steps:
1. Make sure you’re in the Normal Operating mode,
and then enter the Set Omni mode function by
pressing F-OMNI . The FUNCTION LED
illuminates, and the OMNI LED flashes telling
you you’re in the Set Omni Mode function (see
the diagram below). The SYSTEM display
shows the current status of Omni mode ( ON or
OFF).
2. Use the UP or DOWN key to toggle Omni mode
on or off.
3. Press F-OMNI to return to Normal Operating
mode when you’re finished. The FUNCTION
and OMNI LED’s turn off.
When Omni mode is on, and you are setting the
MIDI channel (as described in the previous section),
the MIDI CHANNEL LED flashes to remind you
the MIDI channel number only applies to transmit-
ted messages.
Enabling MIDI Program Change Output
The MPE can be instructed to transmit MIDI
program change commands whenever a Stored
Memory is recalled via the MPE front panel. To do
so, perform the following steps:
1. Make sure you’re in Normal Operating mode, and
then enter the Set Program Change Output func-
tion by pressing F-PRGCHG . The FUNCTION
LED illuminates, and the PRGCHG LED flashes
indicating you are in this function (as shown
below). The current status of the MIDI Program
Change Output option appears in the SYSTEM
display (
on on
or
off off
).
2. Use the UP or DOWN key to toggle MIDI
Program Change Output status on or off.
3. Press F-PRGCHG to return to Normal Operating
mode when you’re finished. The FUNCTION
and PRGCHG LED’s turn off.
Programming The MIDI Map
When the MPE receives a MIDI program change
command, it recalls a Stored Memory. The particular
Stored Memory that gets recalled is determined by
the MIDI map.
Without the MIDI map, a received MIDI program
change “X” would recall Stored Memory “ X ”.
Program change 25 would recall Stored Memory
25
. This is very rigid. For example, if you are
preparing an equalization curve for a particular
portion of a song, you have to ensure that the Stored
Memory number matches all the other devices in your
MIDI system. Otherwise, when your MIDI sequencer
sends the program change command for this passage,
the MPE would recall the wrong Stored Memory.
The MPE MIDI map redirects received MIDI
program change commands to any Stored Memory.
It can be thought of as a simple table, as shown
below. When MIDI program change “X” is received,
Stored Memory “
Y
” is recalled.
