Introducing Version 4.0Owner's Manual Addendum

1. Introducing Version 4.0

Congratulations on your purchase of the MRC V4.0 MIDI Remote Controller. Version 4.0 adds some significant new features and changes to Version 3.0 of the MRC. These changes and features are based on feedback from present MRC users.This addendum is not a replacement of the Version 3.0 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 guidelines for the MRC. We also suggest that you read

in this addendum for the best understanding of MRC control with any LXP

effects processor.

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

user registers directly from Lexicon LXP-1, LXP-5, and LXP-15 multieffects 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• The PCM-70 machine type has been replaced by the LXP-15 machine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.)

2. 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 communication. 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 provided by a computer equipped with editor/librarian programs for the three 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.

If you’re using a computer with your MIDI system, you can run your favorite 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)

2-1

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

• Record the movements of MRC sliders and external controllers with any

MIDI sequencer, allowing the MRC to function as an

automated

effects

controller

One-way and Two-way Communications

Depending on the application, MIDI systems can be configured for one-way or two-way communication. For example, when a MIDI keyboard is used to control a MIDI sound module, one-way communication is usually sufficient. A single cable is run from MIDI OUT on the keyboard to MIDI IN on the sound module. This is generally thought of as a master/slave system. Additional 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 MIDI OUT to the MIDI IN of synthesizer. This sends the recorded 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 settings from the effects device into the computer, and download them from the computer back into the effects unit.

2-3

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 simple matter to connect additional devices to a two-way configuration. This is because MIDI outputs cannot be combined on a single cable without a MIDI

MRC

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 in and out ports and built-in merger allow expanded functionality when used in a two-way configuration. You can, for example, merge selected MIDI controller messages from MIDI IN 2 with MIDI OUT 1. This makes it possible to control an LXP from a MIDI keyboard (or other MIDI controller) while the MRC and LXP are set up for two-way communication.

Two-way communication requires a separate pair of MIDI IN/OUT ports for each LXP being controlled. The MRC has two sets of MIDI IN/OUT ports, so you can control two LXPs in two-way at once using two-way communication. Control of more than two LXPs with two-way communication is possible, but requires a MIDI merging device that can handle System Exclusive data. In MIDI systems with additional hardware such as mergers, THRU boxes, or patching devices, the MRC’s two-way functions can be expanded to allow control of more than two LXPs and/or merging of MIDI clock for Tempo patching while maintaining two-way communication.

3. Controlling the LXP-15

The MRC can be used as a dedicated remote controller for the LXP-15. All of the LXP-15 parameters are accessible via the MRC. In addition to being a full-featured editor, the MRC also extends the programmability of the LXP15 by allowing you to create as many as four additional Dynamic MIDI patches for each LXP-15 sound via the MRC’s Machine Edit Mode. Each patch allows you to assign one of a variety of MIDI sources or either of the MRC’s two external inputs to control any LXP-15 parameter. This makes it possible to control the LXP-15 from

per LXP-15 setup, and four per LXP-15 machine.

Be sure to read about MIDI patching in the V3.0 manual.

The MRC and LXP-15 can be connected for either one-way or two-way communication, depending on the application.

One-way Connections

Some examples of applications that call for one-way communications are:

• to connect more than one LXP-15 to the same MRC OUT port

• to route MIDI clock to the LXP-15 for Tempo patches

The MIDI connections are simple. Connect a single MIDI cable from MIDI OUT 1 of the MRC to MIDI IN of the LXP-15 as shown. We use OUT 1 as an example since it is the default. Of course, you can edit an LXP-15 “machine” to transmit on OUT 2 if you wish. (See MRC V3.0 manual).

Establishing One-way Communication

When configured for one-way communication, the MRC is the master, and the LXP-15 is the slave. In order to establish communication after the initial connections are made and both units are turned on, it is necessary to put the LXP-15 in the same “state” as the MRC. The following procedure describes how this is done:

1. On the MRC, enter Machine Select Mode by pressing MACH twice.

2. Use the leftmost slider, the MACH button or the keypad to select an LXP-

15 type machine. (Machine #3 is an LXP-15 machine when the MRC is shipped from the factory.)

3. Confirm that the MIDI cable is connected to the same output as the

displayed “OUT#”.

3-3

Lexicon MRC V4.0/ MIDI Remote Controller

4. Confirm that the LXP-15 is set to receive on the same MIDI channel as

the displayed “CH#”.

5. Press ENTER to put the MRC into Machine Run Mode. The MRC

display will change to show the first page of LXP-15 Setup parameters.

6. Press ✱ to send the MRC Setup parameters to the LXP-15. The

parameter values displayed by the LXP-15 will change to match those displayed by the MRC. (This step only needs to be done the first time communication is established between the two units.)

7. You can confirm that one-way communication has been established by

moving a parameter slider on any of the six MRC parameter pages. The LXP-15 display for that parameter should change to match the new value.

In order to see parameters change on the LXP-15 when MRC sliders are moved, set the LXP-15 “Update” parameter to “ON”, turn PAGE to the appropriate parameter page, and press VIEW to display the parameter values.

With one-way communication, the MRC has no way of “knowing” if the current LXP-15 setup or parameters have been changed. (This could happen for example, by sending a Program Change message to the LXP15 or by changing parameters or setups from the LXP-15 front panel.) If you think the LXP-15 has been changed by some other action, simply press the ✱ key on the MRC to transmit the current MRC values to the LXP-15.

MRC

Using one-way communication, you can control as many as sixteen Lexicon devices at once by defining a separate machine for each device. Multiple LXP-15 control is very easy to set up since the LXP-15 MIDI THRU port can be used to “daisy chain” additional units.When two or more LXP-15s are controlled from the MRC, they (and the MRC machines that control them) should be set to different MIDI channels, or be connected to different MRC OUT ports. Different types of LXPs can share the same MIDI channel and/ or MRC OUT ports.

If you want to process multiple audio sources with

identical

LXP effects, you can daisy chain multiple LXP-15s (or LXP-5s, or LXP-1s) from the same MRC OUT port and set them all to the same MIDI channel. They can all be controlled simultaneously from a single MRC machine.

If you want to use a foot pedal or other analog controller as a patch source for your LXP-15 be aware that you can connect one or two pedals to the MRC instead of to the LXP-15 rear panel Foot Controller jacks. This allows you to control

multiple

LXP-15s (or other LXP processors) from the same pedal(s).

Two-way Connections

Two way communication allows you to access and view parameters stored in the LXP-15’s 128 internal registers. You can connect one or two LXP-15s to the MRC for two-way communication. Two MIDI cables are required for each LXP-15. The LXP-15 MIDI OUT and MIDI IN can be connected to the MRC IN1 and OUT1 or MRC IN2 and OUT2.

Establishing Two-way Communication

When configured for two-way communication, the MRC requests parameter data from the LXP-15 and displays it for editing. The edited values are sent back to the LXP-15. This back and forth communication, or occurs automatically once communication is established between the two units.

In order to establish communication after the initial connections are made and both units are turned on, it is necessary to put the LXP-15 and MRC in the same “state.” With two-way communication you have the option of setting the LXP-15 to the state of the MRC, or of setting the MRC to the state of the LXP-15. The following procedure describes both options:

1. On the MRC, enter Machine Select Mode by pressing MACH twice.

2. Move the leftmost slider all the way up to select “SYSTEMS PARAME-

TERS” and press ENTER. Use switches 1, 2 and 3 to set MIDI MERGE to “OFF” for the IN and OUT connected to the MRC as shown below:

Selecting an LXP-15 Setup

Once communication has been established between the MRC and the LXP15, different internal and external setups can be selected whenever you are running an LXP-15 machine. If the MRC is not currently running an LXP-15 machine type, you must first select one, then select the desired setup. Here’s how :

1. On the MRC, enter Machine Select Mode by pressing MACH twice.

2. Use the leftmost slider, the MACH button or the keypad to select an LXP-

15 type machine. (Machine #3 is an LXP-15 machine when the MRC is shipped from the factory.)

6. Press ENTER to load the setup into the MRC and LXP-15.

Communication Problems

If the MRC is unable to communicate with the LXP-15, it will display one of two error messages: “No Target,” or “SYNCH TIMEOUT.” The “No Target” message is displayed if the MRC cannot “find” the LXP-15. This can occur if the LXP-15 is not connected properly or if it is set to a different MIDI channel than the MRC. To recover from a “No Target” error, it is necessary to reestablish communication with the LXP-15. To do this, repeat the procedure in

Establishing Two-way Communication

The “SYNCH TIMEOUT” message is displayed if MIDI MERGE for the IN/ OUT ports connected to the LXP-15 is set to “ON,” or when MIDI data is received faster than it can be processed by the MRC. To recover from a “SYNCH TIMEOUT” error, simply press ENTER (and confirm that MIDI MERGE is set to “OFF”).

Viewing and Editing LXP-15 Setup Parameters

LXP-15 setup parameters are viewed and edited on six MRC display

pages.

Pages can be selected by pressing PAGE repeatedly, or by pressing the desired page number on the keypad.

To edit LXP-15 parameters from the MRC, simply select the desired page and move the slider of the parameter you want to edit. The new value is displayed on the MRC and transmitted to the LXP-15. (You can see the parameter changes on the LXP-15 when MRC sliders are moved, if the LXP15’s “Update” parameter is set to “ON”, PAGE is turned to the appropriate parameter page, and VIEW is pressed to display the parameter values.)

Using the ✱ and ENTER Keys

While in Machine Run Mode, the ✱ key transmits the current values of all parameters to the LXP-15. Use it to reset the LXP-15 to the values displayed by the MRC. (You would do this, for example, if LXP-15 parameters are inadvertently changed from its front panel.) If you are using two-way communication, you can press ENTER to update the MRC to the current parameter values of the LXP-15. This allows you to transfer new settings to the MRC after front panel adjustment of the LXP-15.

LXP-15 Display Pages

The LXP-15 has five processing algorithms: Delay/Reverb, Pitch/Delay, Gate, Plate and Chorus Delay. The following charts show the MRC display pages for the parameters of each LXP-15 algorithm . (The LXP-15 parameters are shown with their ranges immediately below each MRC label.)

NOTE: There are some slight differences in the labeling and grouping of parameters on the MRC and LXP-15: The LXP-15 displays five parameters at a time, the MRC displays four. The LXP-15 and MRC have different limits as to the number of characters a label can have. The MRC also provides a fine and coarse control for delay parameters.

MRC/LXP-15 Presets

When shipped from the factory, MRC Version 4.0 has 10 setups loaded into its internal memory. Six additional memory spaces are left blank. You may want to use these setups as is, or modify them to your own taste. Be aware that changes you make will overwrite the factory-loaded setups when you perform a store operation. Brief descriptions of the 10 presets follow:

#1 Big Hall

This is a preset which emulates a rather large space (67 meters) with a long decay time (2.1s). This preset will add depth to any sound source. Great starting point for vocals.

#2 My Room

This preset is a smaller space (31 meters) with a strong reflection added for wall simulation. The bottom end is rolled off to reduce muddiness. This preset was originally written with guitar in mind. However, it's a good basic fill with anything.

#3 Glide Rm

This preset makes use of the gliding delay line which modulates moderately slowly in combination with a medium size room. If it sounds too strange, bring the LFO Rate up to 2.12Hz. Experiment also with changing the RMIX (Reverb Mix) control.

#4 DelyVerb

This preset combines 70ms delay reflection with a small (18 meters) tight (0.7s) room. Good on anything.

#5 HarmMIDI

This preset makes use of Dynamic MIDI patching where MIDI Note values are scaled to the coarse pitch parameter. NOTE: In cases where no MIDI Note data is being transmitted into the LXP-15, the default pitch will be -2 octaves.

3-18

Owner's Manual Addendum

Controlling the LXP-15

#6 Eko Roll

This multi-effects preset combines 60ms and 90ms of delay to the left and right outputs. The pitch shifter is lowered slightly to create a chorusing effect. The reverb is mixed 50/50 with the delay section. It has a small/tight character, but with a 30ms pre-delay for additional space separation from the source.

#7 Gate It

Get it?

#8 V4 Plate

This reverb preset is pretty close to a well-tuned plate. 40ms of pre-delay is utilized for space. Change the SIZE parameter to suit the application.

#9 V4Chorus

Straight ahead multivoice chorus. Sound sources generally "fatten up" when put through this preset.

#10 ChorsEko

This preset combines recirculating echoes with a moderate chorusing effect. Adjust Dely3 to fit the tempo of the sound source. Great effect on lead or vocal tracks.

Controlling the LXP-5 with Two-Way Communication

Establishing Two-way communication

When configured for two-way communication, the MRC requests parameter data from the LXP-5 and displays it for editing. The edited values are sent back to the LXP-5. This back and forth communication, or

hand shaking

occurs automatically once communication is established between the two units.

In order to establish communication after the initial connections are made and both units are turned on, it is necessary to put the LXP-5 and MRC in the same “state.” With two-way communication you have the option of setting the LXP-5 to the state of the MRC, or of setting the MRC to the state of the LXP-5. The following procedure describes both options:

1. On the MRC, enter Machine Select Mode by pressing MACH twice.

2. Move the leftmost slider all the way up to select “SYSTEMS PARAMETERS” and press ENTER. Use switches 1, 2 and 3 to set MIDI MERGE to “OFF” for the IN and OUT connected to the MRC as shown below:

If the LXP-5 is connected to IN/OUT1 . . .

MIDI MERGE

IN1 -> OUT1 <OFF>

If the LXP-5 is connected to IN/OUT2 . . .

MIDI MERGE

3. Press ENTER to return to Machine Select Mode.

4. Use the leftmost slider, the MACH button or the keypad to select an LXP5 type machine. (Machine #2 is an LXP-5 machine when the MRC is shipped from the factory.)

5. Confirm that the MIDI cables are connected to the same input/output pair as the displayed “OUT#”.

6. Press ENTER to put the MRC into Machine Run Mode. The MRC display will change to show the first page of LXP-5 Setup parameters.

4-3

Lexicon MRC V4.0/ MIDI Remote Controller

7. Confirm that the LXP-5 and MRC are set to the same MIDI channel by pressing the LEARN button on the LXP-5 while moving any of the sliders on the MRC. The LED on the LXP-5 will flicker.

8*. To set the LXP-5 to the same state as the MRC, press ∗ to send the MRC

Setup parameters to the LXP-5. The parameter values displayed by the LXP-5 will change to match those displayed on the MRC.

OR To set the MRC to the same state as the LXP-5, press ENTER on the

MRC to send the LXP-5 parameters to the MRC. The parameters displayed by the MRC will change to show the values received from the LXP-5

9. You can confirm that two-way communication has been established by selecting a new register from the LXP-5 front panel and then pressing ENTER on the MRC. The MRC’s displays will change to the parameter values of the new register.

* (Step 8 only needs to be done the first time communication is estab-

lished between the two units.)

With two-way communication, you can update the MRC values to match those currently active in the LXP-5. This is particularly useful if you’ve changed the LXP-5 from its front panel and want to transfer the new settings to the MRC for further editing. To update the MRC simply press ENTER at any time while you are in Machine Run Mode. This will automatically transfer and display the active LXP-5 parameters.

Using two-way communication you can control two LXP-5s at once, one for each input/output pair. If you have a high quality MIDI merger you can control multiple LXP-5s on the same input/output pair. (Each LXP-5 and its corresponding MRC machine must be assigned to a different MIDI channel.)

As long as the LXP-5 MIDI OUT is connected to the appropriate MRC IN you can maintain two-way communication with it, even if other devices are daisy chained to the MRC OUT. This is useful, for instance, when you want to control the LXP-5 and one or more sound modules from a sequencer or keyboard. (See illustration.)

Selecting an LXP-5 Setup

Once communication has been established between the MRC and the LXP5, different internal and external setups can be selected whenever you are running an LXP-5 machine. If the MRC is not currently running an LXP machine, you must first select one, then select the desired setup. Here’s how

1. On the MRC, enter Machine Select Mode by pressing MACH twice.

2. Use the leftmost slider, the MACH button or the keypad to select an LXP-

5 type machine. (Machine #2 is an LXP-5 machine when the MRC is shipped from the factory.)

3. Press ENTER to put the MRC into Machine Run Mode.

4. Press SETUP to enter Setup Select Mode.

5. Use the leftmost slider, the SETUP button, or the keypad to select the

desired setup.

Pressing ∗ on the keypad switches the display between “SETUP#”

and “EXTRN#”. While “SETUP#” is displayed, you can use the keypad to select any internal setup (1–16). While “EXTRN#” is displayed, you can use the keypad to select any external setup (1–

128).

6. Press ENTER to load the setup into the MRC and LXP-5.

Communication Problems

If the MRC is unable to communicate with the LXP-5, it will display one of two error messages: “No Target,” or “SYNCH TIMEOUT.” The “No Target” message is displayed if the MRC cannot “find” the LXP-5. This can occur if the LXP-5 is not connected properly or if it is set to a different MIDI channel than the MRC. To recover from a “No Target” error, it is necessary to reestablish communication with the LXP-5. To do this, repeat the procedure in

Establishing Two-way Communication

The “SYNCH TIMEOUT” message is displayed if MIDI MERGE for the IN/ OUT ports connected to the LXP-5 is set to “ON,” or when MIDI data is received faster than it can be processed by the MRC. To recover from a “SYNCH TIMEOUT” error, simply press ENTER (and confirm that MIDI MERGE is set to “OFF”).

Viewing and Editing LXP-5 Setup Parameters

LXP-5 setup parameters are viewed and edited on seven MRC display

pages.

Pages can be selected by pressing PAGE repeatedly, or by pressing

the desired page number on the key pad. To edit LXP-5 parameters from the MRC, simply select the desired page and

Using the ✱ and ENTER Keys

While in Machine Run Mode, the ✱ key transmits the current values of all parameters to the LXP-5. Use it to reset the LXP-5 to the values displayed by the MRC. (You would do this, for example, if LXP-5 parameters are inadvertently changed from its front panel.) If you are using two-way communication, you can press ENTER to update the MRC to the current parameter values of the LXP-5. This allows you to transfer new settings to the MRC after front panel adjustment of the LXP-5.

Storing Setups from Machine Run Mode

You can store a setup you’ve created in any one of the MRC’s sixteen internal setups, or in any one of the LXP-5’s 128 user registers. Here’s how:

MRC/LXP-5 Presets

#1 DetunHall

This preset offers a combination of reverb with a slight pitch shift which gives a smooth chorusing effect. Adjust the RLVL to suit your application. This preset was originally written with a clean, compressed guitar in mind.

#2 MATdelay

Use MIDI Tempo to automatically set the coarse delay times for Delay 2 and Delay 3.

#3 SloFlang

Slow Flange is intended to be used totally wet through a pre-fader send for maximum effect.

#4 SlapDetn

This Pitch/Delay preset combines 155ms master delay with a slight pitch shift down. A short, bright reverb is mixed 59% into the delay sound. This preset works well on guitar or smooth background voices.

#5 ChorusUp

This is a Pitch/Delay preset which combines a moderate amount of feedback (44%) with a 46ms delay line which is pitched up +2 fine steps. The whole effect is then blended into a reverb module which is moderately sized. This is a way cool, heavy effect.

#6 E/G Slap

This is a Delay/Reverb preset which uses a filtered (2.49k) delay line set to 90ms with a 22% feedback ratio.

#7 On Stage

This preset combines an early reflection of 24.5ms with a moderately large space incorporating a 40ms pre-delay. Great for voice or instruments.

#8 Chamber

This preset is a straight ahead reverb with a slight early reflection set to 24ms. The chamber is bright and mid-sized. Really a great sounding preset for anything.

#9 Linoleum

This preset is kind of like a tiled rest room, only a little duller. The reverb time is exaggerated in length, but can be easily modified to suit your taste.

#10 Sweep It

This is a Delay/Reverb preset with a slowly swept delay line with a nicely bloomed reverb effect. You can use this on tracks which are doubled for a much glitzier final product.

5. Controlling the LXP-1 with Two-Way Communication

Two-way Connections

Two way communication allows you to access and view parameters stored in the LXP-1’s 128 internal registers. You can connect one or two LXP-1s to the MRC for two-way communication. Two MIDI cables are required for each LXP-1. The LXP-1 MIDI OUT and MIDI IN can be connected to the MRC IN1 and OUT1 or MRC IN2 and OUT2.

Owner's Manual Addendum Controlling the LXP-1 with Two-Way Communication

Establishing Two-way communication

When configured for two-way communication, the MRC requests parameter data from the LXP-1 and displays it for editing. The edited values are sent back to the LXP-1. This back and forth communication, or

hand shaking

occurs automatically once communication is established between the two units.

In order to establish communication after the initial connections are made and both units are turned on, it is necessary to put the LXP-1 and MRC in the same “state.” With two-way communication you have the option of setting the LXP-1 to the state of the MRC, or of setting the MRC to the state of the LXP-1. The following procedure describes both options:

1. On the MRC, enter Machine Select Mode by pressing MACH twice.

2. Move the leftmost slider all the way up to select “SYSTEMS PARAME-

TERS” and press ENTER. Use switches 1, 2 and 3 to set MIDI MERGE to “OFF” for the IN and OUT connected to the MRC as shown below:

If the LXP-1 is connected to IN/OUT1 . . .

MIDI MERGE

IN1 -> OUT1 <OFF>

If the LXP-1 is connected to IN/OUT2 . . .

3. Press ENTER to return to Machine Select Mode.

4. Use the leftmost slider, the MACH button or the key pad to select an

LXP-1 type machine. Machine #1 is an LXP-1 machine when the MRC is shipped from the factory.

5. Confirm that the MIDI cables are connected to the same input/output

pair as the displayed “OUT#”.

6. Press ENTER to put the MRC into Machine Run Mode. The MRC

display will change to show the first page of LXP-1 Setup parameters.

5-3

7. Confirm that the LXP-1 and MRC are set to the same MIDI channel by

pressing the MIDI button on the LXP-1 while moving any of the sliders on the MRC. The MIDI LED on the LXP-1 will flicker.

8*. To set the LXP-1 to the same state as the MRC, press ∗ to send the MRC

Setup parameters to the LXP-1. The parameter values displayed by the LXP-1 will change to match those displayed by the MRC.

OR To set the MRC to the same state as the LXP-1, press ENTER to send

the LXP-1 parameters to the MRC. The parameters displayed by the MRC will change to show the values received from the LXP-1

9. You can confirm that two-way communication has been established by

selecting a new preset from the LXP-1 front panel and then pressing ENTER on the MRC. The MRC’s displays will change to the parameter values of the new register.

* (Step 8 only needs to be done the first time communication is estab-

lished between the two units.)

With two-way communication, you can update the MRC values to match those currently active in the LXP-1. This is particularly useful if you’ve changed the LXP-1 from its front panel and want to transfer the new settings to the MRC for further editing. To update the MRC simply press ENTER at any time while you are in Machine Run Mode. This will automatically transfer and display the active LXP-1 parameters.

Using two-way communication you can control two LXP-1s at once, one for each input/output pair. If you have a high quality MIDI merger you can control multiple LXP-1s on the same input/output pair. (Each LXP-1 and its corresponding MRC machine must be assigned to a different MIDI channel.)

As long as the LXP-1 MIDI OUT is connected to the appropriate MRC IN you can maintain two-way communication with it, even if other devices are daisy chained to the MRC OUT. This is useful, for instance, when you want to control the LXP-1 and one or more sound modules from a sequencer or keyboard. (See illustration.)

It is important to realize that all machines defined in the MRC are active even when they are not being displayed. This means that if you use Machine Edit Mode to create an LXP-1 machine with MIDI patches (as described in

Dynamic MIDI

in the MRC V3.0 manual), the LXP-1 will be controlled by those patches no matter what parameters (from any machine type) are being displayed on the MRC. This feature makes it possible for the MRC to simultaneously control as many as sixteen LXPs and other MIDI devices in any combination.

Selecting an LXP-1 Setup

Once communication has been established between the MRC and the LXP1, different internal and external setups can be selected whenever you are running an LXP-1 machine. If the MRC is not currently running an LXP machine, you must forst select one, then select the desired setup. Here’s how :

1. On the MRC, enter Machine Select Mode by pressing MACH twice.

2. Use the leftmost slider, the MACH button or the keypad to select an LXP-

1 type machine. (Machine #1 is an LXP-1 machine when the MRC is shipped from the factory.)

Lexicon MRC V4.0/ MIDI Remote Controller

3. Press ENTER to put the MRC into Machine Run Mode.

4. Press SETUP to enter Setup Select Mode.

5. Use the leftmost slider, the SETUP button, or the keypad to select the

desired setup.

Pressing ∗ on the keypad switches the display between “SETUP#” and

“EXTRN#”. While “SETUP#” is displayed, you can use the keypad to select any internal setup (1–16). While “EXTRN#” is displayed, you can use the keypad to select any external setup (1–128).NOTE: When shipped from the factory, there are no parameter values stored in any of the LXP-1’s 128 user registers. These registers are displayed on the MRC as “NoName N/A.” If you try to load a “NoName N/A” register into the MRC, you will see an “INVALID SETUP” message. This simply means that there are no parameter values assigned to that register (so there’s nothing to load). You must store parameter values into a user register before you can load it. (See

Mode

Storing Setups from Machine Run

6. Press ENTER to load the setup into the MRC and LXP-1.

Communication Problems

If the MRC is unable to communicate with the LXP-1, it will display one of two error messages: “No Target,” or “SYNCH TIMEOUT.” The “No Target” message is displayed if the MRC cannot “find” the LXP-1. This can occur if the LXP-1 is not connected properly or if it is set to a different MIDI channel than the MRC. To recover from a “No Target” error, it is necessary to reestablish communication with the LXP-1. To do this, repeat the procedure in

Establishing Two-way Communication

The “SYNCH TIMEOUT” message is displayed if MIDI MERGE for the IN/ OUT ports connected to the LXP-1 is set to “ON,” or when MIDI data is received faster than it can be processed by the MRC. To recover from a “SYNCH TIMEOUT” error, simply press ENTER (and confirm the MIDI MERGE is set to “OFF”).

Viewing and Editing LXP-1 Setup Parameters

LXP-1 setup parameters are viewed and edited on two MRC display

pages.

Pages can be selected by pressing PAGE repeatedly, or by pressing the desired page number on the keypad.

To edit LXP-1 parameters from the MRC, simply select the desired page and move the slider of the parameter you want to edit. The new value is displayed on the MRC and transmitted to the LXP-1. (You will see the MIDI LED flicker when sliders are moved on the MRC.) Refer to the

parameters.

Using the

✳

and ENTER Keys

While in Machine Run Mode, the ✳ key transmits the current values of all parameters to the LXP-1. Use it to reset the LXP-1 to the values displayed by the MRC. (You would do this, for example, if LXP-1 parameters are inadvertently changed from its front panel.) If you are using two-way communication, you can press ENTER to update the MRC to the current parameter values of the LXP-1. This allows you to transfer new settings to the MRC after front panel adjustment of the LXP-1.

Storing Setups from Machine Run Mode

You can store a setup you’ve created in any one of the MRC’s sixteen internal setups, or in any one of the LXP-1’s 128 user registers. Here’s how:

1. On the MRC, press STORE to enter Setup Store Mode.

2. Move slider 2 to select “MRC SETUP” or “LXP-1 RGSTR”

3. Use slider 1, the SETUP key or the keypad to select a setup number.

(The display will blink if you enter an invalid number. Valid numbers for MRC setups are 1–16. For LXP-1 registers valid numbers are 1–128.)

4. Press ENTER to store the setup and return to Machine Run Mode

Changing LXP-1 MIDI THRU to MIDI OUT

Using a Phillips-head screwdriver, remove the 2 screws from either side of the LXP-1 front panel. Do a 9/16" nut driver, or miniature pliers, carefully unscrew the 5 nuts and washers surrounding the 1/4" jacks labeled DEFEAT, OUTPUTS and INPUTS.

Holding the unit with both hands, gently separate the outer case from the front panel. Slide the front panel and its circuit board out of the case. Avoid

touching any of the parts on the board unless you are confident that both you and your LXP-1 are properly grounded. (The thin rubber

protectors on the sides of the circuit board may come off. These can easily be replaced prior to reinserting the board and the front panel.)

Locate the single small jumper (usually a small blue plastic piece) at the back of the circuit board close to the MIDI jacks. Lift the jumper off of the two pins it is sitting on and place it on the two pins beside it. Your MIDI THRU port is now a MIDI OUT port.

not

remove the two screws on the rear panel. With

Carefully reinsert the board into the outer case, sliding the rubber protectors into their grooves. Seat the front and rear panel properly so that the 1/4" jacks protrude from the proper holes. Replace the 5 washers and nuts without over-tightening them. Replace the 2 front panel screws. Your LXP1 is now ready to communicate with the Version 4.0 MRC.

After performing this procedure once, you will se that the changeover is very quick and simple. If you ever want the port to act as a MIDI THRU again, you can always move the jumper back to its orginal position.
