INSTALLATION

Connect your MIDI cables as follows:

MX-28M Inputs

Route the OUTPUT from one “source” (e.g. your controller keyboard) to one of the
INPUTS on the MX-28M. Route the OUTPUT from another “source” (e.g. your
sequencer) to the other input on the MX-28M.

MX-28M Outputs

Route each of the eight MX-28M OUTPUTS to the INPUTS of your tone modules,
sequencer, etc. (the “destinations” for your MIDI data).

Plug the Power Adapter into a suitable wall outlet. Plug the Power Adapter connector
into the power jack on the MX-28M.

ROUTING

For each MX-28M OUTPUT, use the corresponding three-position switch to select either
INPUT 1, INPUT 2 or the PROCESSOR as the source for that OUTPUT.

PROCESSING

The MX-28M is extremely easy to program. Transpose intervals and map zones are
selected directly from your controller keyboard connected to INPUT 1.

Select one of the three processing functions with the three-position Function Select
Switch. Processed data can be assigned to any OUTPUT(s), and each of the INPUTS can
still be assigned individually.

Merge

In Merge mode, the MX-28M will merge data from INPUT 1 with the data from INPUT

2.

Transpose

Select TRANSPOSE (the middle position) with the Function Select Switch. When the
PGM button is depressed briefly (see RESET), the Red LED above the word
“TRANSPOSE” will blink rapidly and the Green LED above the word “FROM” will
illuminate.

Press the note on your keyboard that defines the key you wish to transpose from. The
Green LED above the word “TO” will illuminate. Press the note on your keyboard that
defines the key you wish to transpose to.

Example:
If you are playing in the key of C and you wish to transpose to the key of F#, you would
perform the following sequence.

1. Select TRANSPOSE.

2. Press PGM button.

3. Play C on your keyboard connected to INPUT 1.

4. Play F# on your keyboard.

Transposed MIDI data is send to each selected output.

Map

In MAP mode, four completely independent zones can be defined. These zones can be
splits, layers or combinations of both. Each zone is then output on its own MIDI channel
to each selected output. The first defined zone is transmitted on the same MIDI channel
number as the input channel number, and each of up to three additional zones are output
on the next higher MIDI channel number.

Example:
If four zones are defined and the input channel is MIDI channel 4, the zones will be
output as follows.
zone 1 on channel 4
zone 2 on channel 5
zone 3 on channel 6
zone 4 on channel 7

Select MAP (the uppermost position) with the Function Select Switch. The default MAP
sends the entire keyboard range to all four zones (i.e. four channels are layered on each
note) for instant LAYERING.

To define SPLITS and LAYERS in any combination, press the PGM button. When the
PGM button is pressed, the Red LED above the word “RANGE” will blink to indicate
