Installation Instructions & Release Notes

SAFETY SUMMARY

The following general safety precautions must be observed during all phases of operation, service, and repair of this unit. Failure to comply with

these precautions or with specific warnings elsewhere in these instructions violates safety standards of design manufacture and

intended use of this unit. Lexicon, Inc. assumes no liability for failure to comply with these requirements.

GROUND THE INSTRUMENT

To minimize shock hazard, the unit chassis and cabinet must be

connected to an electrical ground. The unit is equipped with a three-

conductor AC power cable. The power cable must be either plugged

into an approved three-contact electrical outlet or used with a three-

contact to two-contact adapter with the grounding wire (green) firmly

connected to an electrical ground (safety ground) at the power outlet.

The power jack and mating plug of the power cable meet International

Electrotechnical Commission (IEC) safety standards.

DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE

Do not operate the unit in the presence of flammable gasses or

fumes. Operation of any electrical instrument in such an environment

constitutes a definite safety hazard.

KEEP AWAY FROM LIVE CIRCUITS

Operating personnel must not remove unit covers. Component

replacement and internal adjustments must be made by qualified

maintenance personnel. Do not replace components with power cable

connected. Under certain conditions, dangerous voltages may exist

even with the power cable removed. To avoid injuries, always

disconnect power and discharge circuits before touching them.

DO NOT SERVICE OR ADJUST ALONE

Do not attempt internal service or adjustment unless another person

capable of rendering first aid resuscitation is present.

DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT

Because of the danger of introducing additional hazards, do not install

substitute parts or perform any unauthorized modification to the unit.

Dangerous voltages capable of causing death are

present in this instrument. Use extreme caution

when handling, testing, or adjusting.

WARNING

These service instructions are intended for use by

qualified personnel only. Do not perform any

servicing other than that contained in these

instructions unless qualified to do so. Refer to the

Safety Summary on page 2 prior to performing

any service.

WARNING

ELECTROSTATIC DISCHARGE

(ESD) PRECAUTIONS

The following practices minimize possible damage to ROMs resulting from

electrostatic discharge or improper insertion.

• Keep parts in original containers until ready for use.

• Avoid having plastic, vinyl, or Styrofoam in the work area.

• Wear an anti-static wrist strap.

• Discharge personal static before handling devices.

• Remove and insert boards with care.

• When removing boards, handle only by non-conductive surfaces and

never touch open-edge connectors except at a static-free workstation.*

• Minimize handling of ROMs.

• Handle each ROM by its body.

• Do not slide ROMs or boards over any surface.

• Insert ROMs with the proper orientation, and watch for bent pins on ROMs.

• Use anti-static containers for handling and transport.

* To make a plastic-laminated workbench anti-static, wash with a solution of

Lux liquid detergent, and allow to dry without rinsing.

PRESERVING USER BANK PROGRAMS &

SYSTEM SETTINGS

User Bank programs will be preserved during the

software installation process. But, to avoid accidental

initialization of User Bank programs and other system

settings, it is recommended to dump system information

to an external MIDI storage device before installing the

new software. To do this, refer to the instructions that

begin at the top of the next column.

System select: 

Audio

If desired, follow the instructions that begin below to

perform MIDI dumps of system information and User

Bank programs:

1. Connect a 5-pin MIDI cable from the MPX G2 to an

external MIDI storage device. This cable should be

connected from the MIDI OUT connector on the

MPX G2 to the MIDI IN connector on the external

MIDI device.

2. Press the front panel System button to enable

System Mode. The front panel display will appear as

shown in the figure below.

3. Rotate the front panel selection knob two clicks to

the right, until the MIDI option is selected as shown

in the figure at the top of the next page. The

selection knob is located to the right of the Effect

buttons.

4. Press the front panel > Yes 11 button times, until the

MIDI Dump option is selected as shown in the figure

below. The front panel Store button LED will flash to

indicate that the MPX G2 is armed to transmit a

MIDI dump.

Settings (continued from page 7)

9. When the new software is installed, refer to the

external MIDI storage device documentation to send

the MIDI dumps back to the MPX G2. This will

restore User Bank programs and system settings.

INSTALLATION INSTRUCTIONS

Performing this upgrade is a simple process. But, to avoid

problems, please follow these instructions carefully. Pay

particular attention to precautions that appear in this

document, including the Safety Summary that begins on

page 2. Any damage caused during installation is not

covered under warranty.

1. Using a Phillips head screwdriver, remove the two

rear panel screws identified in the figure at the top of

the next column.

4. Before proceeding to Step 2: Install the ROM:

A. Put on the anti-static wrist strap.

B. Attach the copper tape to the MPX G2 chassis.

STEP 2: INSTALL THE ROM

1. Refer to the figure below to locate the ROM on the

MPX G2 main board (location U93).

2. Examine the ROM provided in the upgrade kit.

Because the manufacturing process leaves the pins

angled out slightly from the ROM body, the pins

must be straightened before insertion.

To straighten the pins:

A. Place the ROM on its side on a static-free, flat

surface. See page 3 for instructions to create a

static-free workstation.

B. Hold the body of the ROM. Gently exerting

pressure downward, roll the ROM back and forth

to force both rows of pins into a position parallel

to the workstation. This is demonstrated in the

figure below.

. . . Step Two: Install the ROM continues on page 10

Software Version 1.1 Installation Instructions & Release Notes Lexicon

Step 2: Install the ROM (continued from page 9)

3. Using the ROM extractor tool as shown in the figure

below, remove the ROM from location U93.

ROMs inserted backwards might be destroyed.

Incorrect insertion of ROMs might also cause

damage to the board. Make sure the notch on the

ROM aligns with the notch on the ROM socket.

Damage caused during installation is not covered

under warranty.

CAUTION

4. Insert the Software Version 1.1 ROM in place of the

old ROM. Be careful not to bend the pins. The notch

on the ROM (shown in the figure below) should

align with the notch on the ROM socket. When the

ROM is inserted, inspect the pins to make sure none

have been bent.

RELEASE NOTES

Software Version 1.1 includes the new enhancements

described in this section.

• The Time parameter in the Delay (S), Delay (D), Echo

(S), and Echo (D) effects can now be set above 5,000

milliseconds without creating ping pong effects.

• When working with MIDI Pgm Maps, different

Program Change messages can now be assigned to

the same program.

• Program Change messages with values greater than

100 will no longer activate the "Sort programs by

number" feature when sent to the unit. Rather, these

messages will select the corresponding MIDI Pgm Map.
