of the MRC. These changes and features are based on feedback from
presentMRC users.This addendum is nota replacement of the Version3.0
MRC Owner’s Manual. It describes only the new features and changes
added by Version 4.0. If you are new to the MRC and MIDI control, be sure
to refer to the V3.0 manual for general descriptions of, and operational
guidelinesfortheMRC.Wealsosuggest thatyouread ControllingtheLXP-

V4.0 Features
The following features have been added to the MRC by Version 4.0:
•The MRC can now control the Lexicon LXP-15 Multi-Effects Processor.
A new machine type for the LXP-15 has been added to the MRC’s
machine definitions.
• Two-way communication has been added to allow the MRC to upload
user registers directly from Lexicon LXP-1, LXP-5, and LXP-15 multi-
effects processors for parameter display and control.
V4.0 Changes
The following changes have been made by Version 4.0:
•The PCM-70 machine type has been replaced by the LXP-15 machine
type. Although Version 4.0 cannot be used as a dedicated controller for
the PCM-70, you can still control the PCM-70 from a GMIDI machine
type.
•The two-way communication features of Version 4.0 eliminate the need
to hold large banks of LXP-1, LXP-5, and LXP-15 setups in internal
memory. (Each LXP-type machine can access sixteen internal MRC
presets and 128 external LXP registers.)

Owner's Manual Addendum Controlling the LXP Series of Multi-Effects Processors
One of the most powerful features of the MRC is its ability to be used as a
dedicated controller for Lexicon’s LXP-1, LXP-5 and LXP-15 multi-effects
processors. For maximum flexibility with your setup, the MRC can control
LXP devices using either one-way or two-way MIDI communication. This
section presents the general issues of MRC/LXP control and communica-
tion. The following sections provide specific information for MRC control of
each type of LXP processor.
Advantages of MRC control
As a dedicated LXP controller, the MRC offers functions similar to those
providedbyacomputerequippedwitheditor/librarianprogramsforthethree
LXP effects units, as well as a MIDI merger/mapper. The MRC is much
easier to move around than a computer — so it’s a great way to take MIDI
control on the road.
With its 2€×24 character display and its ability to control up to sixteen LXP
processors simultaneously, the MRC becomes the “front end” to your LXP
devices — just put them in your rack and let the MRC take over.
Ifyou’reusingacomputerwithyourMIDIsystem,youcanrunyourfavorite
computer-based sequencer and simultaneously use the MRC to edit and
control your LXPs. (The MRC’s GMIDI functions can also be controlling
other MIDI instruments while the sequencer is running)

Multi-Effects Processors

Lexicon MRC V4.0/ MIDI Remote Controller
The MRC has several advantages as a dedicated remote controller for
Lexicon’s LXP-1, LXP-5, and LXP-15 multi-effects processors. Here are
some of the possibilities:
• Simultaneous editing and display of as many as four parameters
• Access as many as sixteen LXPs from a single MRC
• Route two analog controllers (foot pedals) to multiple LXPs
• Enhances programmability of the LXP-1 (The MRC lets you control
parameters that aren’t accessible from the LXP-1 front panel. Internal
Dynamic MIDI patches are expanded from two to four
• Finer control resolution of LXP-1 and LXP-5 parameters
• Fine and coarse control of LXP-15 delay time parameters speeds up
delay programming
• As many as four additional Dynamic MIDI patches per LXP
•Internal storage of sixteen setups each for LXP-1, LXP-5 and LXP-15
machine types
•Recordthe movements ofMRC sliders andexternal controllers with any
MIDI sequencer, allowing the MRC to function as an automated effects
controller
One-way and Two-way Communications
Dependingontheapplication,MIDIsystemscanbeconfigured forone-way
or two-way communication. For example, when a MIDI keyboard is used to
controla MIDI sound module, one-way communication is usually sufficient.

slaves can be controlled by the master via MIDI THRU.

Owner's Manual Addendum Controlling the LXP Series of Multi-Effects Processors
Two-way communication is used for more sophisticated applications. For
instance, in order for a sequencer to record and playback MIDI data from a
single synthesizer, they must be set up for two-way communication. Two
cables are required. One is run from the synthesizer’s MIDI OUT to the
sequencer’s MIDI IN. This sends the MIDI data from the synthesizer to the
sequencer where it is recorded. Another cable is run from the sequencer’s
MIDIOUT to the MIDI IN of synthesizer. This sendstherecorded MIDI data
back to the synthesizer, where it is played.
Editor/librarian programs for MIDI effects units are other examples of
applications that require two-way communication to upload parameter
settingsfromtheeffectsdevice intothecomputer,and downloadthemfrom
the computer back into the effects unit.

Lexicon MRC V4.0/ MIDI Remote Controller
It is important to note that two-way communication creates a closed-loop
between the two MIDI devices. Unlike a one-way configuration, it is not a
simplemattertoconnectadditionaldevicestoatwo-wayconfiguration.This
is because MIDI outputs cannot be combined on a single cable without a
MIDI merger .
The MRC can be be used in both one-way and two-way configurations.
Since the MRC already “knows”the parameters of the LXP-1, LXP-5 and
LXP-15, it can be used as an editor/librarian in a one-way system. Its dual
inandoutportsandbuilt-inmergerallowexpandedfunctionalitywhenused
in a two-way configuration. You can, for example, merge selected MIDI
controllermessagesfromMIDIIN2withMIDIOUT1.Thismakesitpossible
to control an LXP from a MIDI keyboard (or other MIDI controller) while the
MRC and LXP are set up for two-way communication.
