When an MPX R1 is connected to an MPX G2, two-way communication is

accomplished via MIDI System Exclusive messages. This allows immediate

response by both units to actions on either front panel.

Connect the power adapter provided with the MPX R1 to the MPX G2 REMOTE

POWER input jack and to a wall outlet.

Power up the MPX G2 and connect the 7-pin DIN cable provided with the

MPX R1 between the MPX G2 rear panel IN/REMOTE jack and the MPX R1

MIDI OUT/REMOTE.

The MPX R1 will cycle through a power-up routine, lighting various LEDs, and

then display Con. The MPX G2 will display Remote Connected. These

messages indicate that proper bidirectional control has been established.

When the MPX G2 powers up, it will default to Program Mode. The MPX R1

should also power up in Program Mode. (FX button LED should be off.) In this

mode, the MPX R1 sends MIDI Program Change and Bank Select messages to

load MPX G2 programs.

These four switches and continuous controller transmit specific MIDI System

Exclusive or Control Change messages regardless of the mode of operation.

In this mode, the state of A/B and the Tempo LED rate will automatically update

to the state of the currently loaded program. For example, if you load a program

set to 100 beats per minute (BPM), the MPX R1 will flash at 100 BPM, just as

the MPX G2 does. If you then load a program set to 120 BPM, the Tempo LED

on the MPX R1 will increase from 100 to 120 BPM when the new program loads.

Pressing and holding the TAP button on the MPX R1 will display the current

tempo in BPM on the R1 display.

The first two digits on the display indicate the bank number. The third digit

indicates the program number. The BANK buttons select banks, and switches

0-9 select programs within the displayed bank. Programs are loaded whenever

one of the numbered switches is pressed.

To load a new program within the same bank, press any of the numbered

switches (0-9).

To select a program in a different bank, press the BANK buttons to step to the

bank you want, or hold down either button to scroll through the numbers. The

rightmost digit, which is reserved for program numbers, will turn off during bank

selection. Once you have selected the desired bank, press the numbered switch

to load the program number within that bank.
