    LXP-5 Owner's Manual Audio Connections This section outlines several connection possibilities for the LXP-5. Be- cause each sound system is unique, we recommend experimentation to arrive at the best configuration for your system. Always check connections for proper impedance, polarity, and levels. Audio connections to the LXP-5 are unbalanced, and should be made with high quality shielded cables with 1/4"...

  • Page 26: Creating Your Own Sounds

    Front Panel Operation Creating your own sounds The LXP-5 contains two algorithms which are used to create its many different and interesting sounds: Pitch/Delay which includes a digital delay line, pitch shifter, EQ and ambience Delay/Reverb which includes a digital delay line, EQ and reverb.
  • Page 27 LXP-5 Owner's Manual The available parameters for each preset are determined by the algorithm used. All PITCH, DELAY, CHORUS and MULTI presets 49-56 use the Pitch/Delay Algorithm. MULTI presets 57-64 use the Delay/Reverb algo- rithm. Editing a preset The easiest way to start creating your own sounds is by editing one of the 64 LXP-5 preset programs.

The maximum delay available is the sum of the largest coarse and fine values.
  • Page 31 LXP-5 Owner's Manual Infinite Reverb and Infinite Loops Both algorithms allow you to create "infinite" effects. The Pitch/Delay algorithm's Delay 1 can be used as a loop sampler, controlled by Feedback 1. Any Pitch/Delay preset can use the loop sampling feature;...
  • Page 32 Front Panel Operation Reverb Balance, Output Level and Output Balance interact. The Output and Reverb Balance parameters are like conventional pan pots, with a 3 dB loss in the center position. When set at 100%, Output Level contributes 6 dB of gain to override these losses and provide the best signal-to-noise ratio.
  • Page 33 LXP-5 Owner's Manual Choosing ADJUST Knob Destination After creating a sound, you can customize your effect by assigning as many as five parameters to the ADJUST knob. This allows you to recall a program, and modify the chosen parameters with the ADJUST knob without going back into Edit mode.
  • Page 34 Front Panel Operation Storing a new sound After creating a new sound, you may want to save it for future use in one of the LXP-5‘s 128 memory locations. New entries will overwrite any program stored at that location, so be careful not to store into a location that contains a setup you want to save.
  • Page 35 LXP-5 Owner's Manual Editing a User program A User program can be modified in the same way as a Preset. First, turn FUNCTION and SELECT to recall the desired program. Enter Edit mode by holding the LEARN button in while turning FUNCTION to EDIT A or B. Release the LEARN button and turn SELECT to a specific parameter.
  • Page 36 Front Panel Operation Changing Algorithms Another way to modify programs is by choosing the LXP-5’s other algorithm. For example, you might like the sound of a program that uses the Delay/ Reverb algorithm, but want to add pitch shifting. To change algorithms: 1.

  • Page 41 LXP-5 Owner's Manual Selecting a MIDI channel Before you can use the LXP-5 with a MIDI controller, both units must be set to the same MIDI channel. To set the LXP-5 MIDI channel: 1. Set the controller you will be using (keyboard, foot controller, etc.) to any MIDI channel (1-16).
  • Page 42 MIDI Operation Storing a program After editing a Preset program with the front panel knobs, you can store the edited program in any of the 128 LXP-5 User memory locations: 1. Connect your MIDI controller and the LXP-5, and set them to the same MIDI channel.

  • Page 43: Patches And Dynamic Midi

    LXP-5 Owner's Manual Living with controller quirks Some synthesizers and controllers cannot send the full range of MIDI program change messages (0-127). With them, you can't access all the registers in the LXP-5. Others may appear to be able to send only 32, but actually have a bank mode that does let you send all 128 program change messages.
  • Page 44 MIDI Operation ADJUST Knob Patch The front panel ADJUST knob can be assigned to as many as five parameters. This patch may be stored with a program in addition to the four general purpose patches. The usefulness and implementation of this patch is discussed in Chapter 2: Front Panel Operation: Choosing ADJUST knob destination.
  • Page 45 LXP-5 Owner's Manual Creating a General Purpose Patch using Edit Mode Edit Mode lets you create a general purpose patch by using the front panel of the LXP-5. First set up the LXP-5 by recalling a program and modifying any parameters to obtain the desired sound. Place this setup in the edit buffer (if it is not already there) by holding in the LEARN button while turning FUNCTION to EDIT C, then releasing LEARN.
  • Page 46 MIDI Operation feedback, you can set the threshold value high enough so the controller will bottom out at 70% and top out at 100%. Sixteen Threshold values from 0 to 127 are available when using Edit mode to create a patch. If MIDI SysEx data is used to create a patch, any value from 0 to 127 may be used for Threshold level.

  • Page 48 MIDI Operation After a patch is created, it can be saved in a register. Up to four general purpose patches may be created and saved in each memory location. Creating a General Purpose Patch using MIDI Learn Mode This method of creating a patch is fairly simple but it limits you to one active general purpose patch at a time.
  • Page 49 LXP-5 Owner's Manual 7. Release the LEARN button. The position of the ADJUST knob at the moment the LEARN button is released will be used to determine the scale factor. If you moved more than one MIDI controller while holding in the LEARN button, the last one moved will be used.

  • Page 50: Creating Patches Using Midi Sysex Data

    LXP-5. A device that is programmed to transmit LXP-5 SysEx data is needed, such as the Lexicon MRC MIDI Remote Controller (with Rev. 3.0 or higher software). The MRC allows you to edit up to eight parameters for each program giving you much greater creative potential.

    LXP-5 Owner's Manual Assigning Switches as Control Sources In addition to continuous controllers, you can patch switches and use them to choose between two parameter values.
