Applications
Now for the fun part, using the MPE. The MPE
hooks up to other audio equipment just like a stan-
dard graphic equalizer. Audio goes in the audio
input and comes back out the audio output. Don’t
forget to connect power to the MPE.
There are an endless variety of MIDI setups that
could accommodate the MPE. A few simple ones
appear below. In all cases, the MIDI OUT of one
device connects to the MIDI IN of another device.
MIDI THRU’s are used for daisy-chaining, but
should not be used to connect more than four de-
vices together. If you need to connect more than four
devices, use a MIDI Thru box (splitter).
If you want to bring the MIDI OUT’s of more
than one MPE to a single device, then you need a
MIDI Merger. MIDI Mergers take two or more
MIDI cables and combine them to one. Never try to
use a Y-connector to combine two or more MIDI
cables. It won’t work.
With these basic ground rules in mind, here are
some typical setups.
Example 1:
One MPE connected as a slave to a MIDI key-
board. Note that any MIDI device could be substi-
tuted for the keyboard.
Example 2:
Two MPE’s in master-slave configuration.
Notice that the MIDI OUT of the master is
connected to the MIDI IN of the slave. With Key
Scan Echo and/or Parameter Echo enabled on the
master, key presses and/or parameter changes are
transmitted to the slave.
Example 3:
Master-slave configuration with 4 slaves, using
MIDI THRU’s .
The keyboard sends MIDI program change com-
mands to the MPE. It also sends MIDI channel
pressure aftertouch or continuous controller data for
the Expression feature.
As in example 2, with the proper SYSEX echo
option enabled, the master controls the slaves.
Each slave is given a different device ID. The
master communicates with each slave independently
by adjusting its device ID to match each slave.
Only use MIDI THRU’s with 4 or less slaves.
