2 IN/2 OUT MIDI MERGER
The Merge 2 x 2 MIDI Merger allows any two incoming
MIDI signals to be merged and sent to either one or
two MIDI devices. Merge 2x 2 can also be used as a 1
In / 2 Out MIDI thru box.
Merge 2 x 2 can be used whenever you have two MIDI
signals that need to go to the same destination. Also,
if you find that your MIDI system has had a “nervous
breakdown,” the 2 x 2 has a built-in “panic button” feature.
Merge 2 x 2 draws power directly from the MIDI Out of
any instrument or sequencer connected to either of its
MIDI Ins -- so it needs no external power supply. The
instrument that is connected to the Merge 2 x 2's MIDI
In must be turned On in order for the 2 x 2 to receive
power. When this is done, the red power LED will light.
IMPORTANT: Merge 2x2 takes 2 or 3 seconds to
power-up after active MIDI is connected to either of its
MIDI Ins. During this brief power-up time the Merge
2x2 will not merge.
To use Merge 2 x 2, connect the MIDI Outs of the
instruments or sequencers you wish to merge to the 2
x 2’s MIDI Ins. Next, connect the Merge 2 x 2's MIDI
Outs to the MIDI Ins of your desired MIDI devices. Both
Merge 2 x 2's MIDI Outs are identical so it doesn't matter which 2 x 2 MIDI Out is connected to which instru-

ment MIDI In.
The Merge 2 x 2 has a built-in “Panic Button” which will
send “all notes off” messages and zero all MIDI controllers and pitch wheels. This feature is activated by
powering down the Merge 2 x 2 and then powering it
back up again. This can be done either by turning off
the power of both instruments connected to the 2 x 2’s
MIDI Ins and then turning them on again, or by disconnecting and then reconnecting both MIDI cables
plugged into the Merge 2 x 2’s MIDI Ins. IMPORTANT:
When powering down the Merge 2x2 in this fashion
make sure power remains off for at least 5 seconds

before turning the power back on. This will ensure
that the 2x2 resets properly.
Merge 2 x 2 is designed to consume almost no power.
However, very rarely you may encounter some older
MIDI device that requires more power than 2 x 2 can
deliver. This can only happen if the instrument draws
more power than allowed in the MIDI specification. If you
encounter this situation, there is a standard 9-volt, center pin positive, power jack on the side of Merge 2 x 2.
You can go to your local electronics store and buy a universal power adapter or call MIDIMAN to purchase one
directly.
