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

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.

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.

11

Software Version 1.1 Installation Instructions & Release Notes

MPX G2

• The Diatonic Hmy effect now corrects pitch in
“down” pitch shifts. Setting the Int parameter to
negative (–) pitch shift setting now provides the
correct interval.

• The Wah2 and PedalWah2 effects will now maintain
accurate output levels when placed in the pre-gain
path. A –3dB change in output level will no longer
occur when either of these effects is assigned in the
Effect 1 bank.

• Footpedals connected to the MPX G2 will now show
proper tuner offset. When the Tuning Cal option is
not set to A=440.00Hz, the setting will display
correctly on an MPXR1 footpedal connected to the
MPX G2. (The Tuning Cal option is available in Tuner
Mode.)

NEW FEATURES

Software Version 1.1 includes the new features described
in this section.

NEW & IMPROVED EFFECTS

• New effects have been added to the Effect 1, Effect 2,
and EQ banks. Descriptions of these effects begin on
the next page. The table beneath each description
indicates the parameters available for the effect.

• The following effects have been added to the EQ
bank: SweepFilter, Wah1, Wah2, PedalWah1,
PedalWah2, Test Tone, and Ring Mod. These effects
are identical to the effects included in the Effect 1
and Effect 2 banks.

• The compressor level in the Wah2 and PedalWah2
effects appears on the same meter as it appears on in
the RedComp effect. The compressor in all three
effects is identical.

. . . New & Improved Effects continues on page 12

Software Version 1.1 Installation Instructions & Release Notes

Lexicon

12

New & Improved Effects (continued from page 11)

• The Blue Comp effect time constant has been
shortened to improve performance when the ATime
parameter is set to 0. The minimum attack time set in
the algorithm is greater than 0. This time is now
faster, making the effect sound less "crunchy" when
the ATime parameter is set to 0. The Blue Comp
effect is located in the Effect 1 and 2 banks.

Comp (S)

The Comp (S) effect has been added to the Effect 1 and 2
banks. It is a stereo version of the Blue Comp effect.
These effects are identical, except Comp (S) has a mono
detector linking the left and right compressors. Comp (S)
includes the ATime (Attack Time) parameter modification
described in the last column. The table shown on the

next page (left column) lists all Comp (S) parameters.

RingMod

The RingMod effect has been added to the Effect 2
and EQ banks. It is modeled after the Moog LC
moogerfooger™. It multiplies a locally generated sine
wave carrier by the input signal, creating sidebands

around the carrier frequency. A built-in LFO modulates
the carrier for added “weirdness.” Harmonics are not
anti-aliased. The table shown on the next page (right

column) lists all RingMod parameters.

NEW PARAMETER OPTIONS

Note:

To access new parameter options, press the front
panel Options button while the desired parameter
is selected.

Mix (0 to 100% or Off, -95 to 0dB)

When the Effect Mix option is selected, the Mix
parameter can be used to set the wet-to-dry ratio of the
input signal as a percentage. When the Dry Level option
is selected, the Mix parameter can be used to set the dry
level of the input signal. (The Level parameter indicates
the wet level of the input signal no matter which option
is selected.)
