  • Page 11 Patch 4 MIDI If you will be using an LXP-15 as your primary effects unit, and your system includes a console with one or more auxiliary (effects) sends, connect the LXP- 15 as shown above. In most applications, it is preferable to connect the LXP-15 outputs to two of the console's input channel strips, panned full left and right, rather than the effects returns.
  • Page 12 LXP-15 between the instrument and console. This makes it possible to keep the LXP-15 up on stage with other MIDI gear, rather than in the console effects rack, making MIDI control much easier.
  • Page 13 L Input R Input For a very spacious guitar sound, connect the LXP-15 between a guitar and two amp and speaker stacks. Set the LXP-15 MIX control to approximately 50%. The only problem with this setup is that if you use overdrive distortion created by the amplifier, changing settings on the LXP-15 also affects the quantity and quality of your distortion.
  • Page 14 If you use overdrive distortion, it's usually better to create the overdrive before sending the signal to the LXP-15 to ensure that the effects don't change the quantity and quality of your distortion. In this setup, you need a guitar pream- plifier or a guitar amp with a direct output.

    If the output you are using doesn't have a level control, don't worry about it! 3. While sending audio to the LXP-15, gradually turn up the INPUT control until the red OVL LED just flashes on the loudest peaks. If it flashes continuously, turn the INPUT control down slightly.

  • Page 27: Delay/Reverb

    The Algorithms To get some idea of the types of sounds and effects that can be created with Delay/Reverb the Delay/Reverb algorithm, be sure to listen to and experiment with presets built on this algorithm. (See Chapter 5: The Presets. ) The Delay/Reverb algorithm consists of an equalizer in series with a unique glide delay line and reverb simulator.
  • Page 28 LXP-15 Owner's Manual Lexicon Delay/Reverb parameters Glide Delay:The master predelay for this algorithm, providing up to 683ms of delay. Glide Delay produces pitch shift effects while it is being modulated. Controlling Glide Delay with the LFO can produce vibrato, chorus and flanging effects.
  • Page 29 The Algorithms Size: Sets the rate of buildup of diffusion after the initial period (which is set by Diffusion). It also acts as a master control for Decay. Because of this link, Size changes a reverb sound from very large to very small. Generally, you should set Size before adjusting anything else.

Interval: Adjusts the pitch shift in semitone increments from two octaves below to one octave above the original pitch. Control this parameter with Last Note, High Note or Low Note for MIDI harmonizer or loop sampler effects.

  • Page 33: Gate

    The Algorithms Gate To get some idea of the types of sounds and effects that can be created with the Gate algorithm, be sure to listen to and experiment with presets built on this algorithm. (See Chapter 5: The Presets.) The Gate algorithm is a reverb effect with a fairly constant sound and no decay until the reverb is cut off abruptly.
  • Page 34 LXP-15 Owner's Manual Lexicon Gate parameters Predelay: A predelay providing up to 262ms of delay. It is located after Treble and Diffusion and before the gated reverb . Relatively short predelay times (60ms or less) will add depth to gate effects that use a mix of wet and dry signal.

    The Algorithms To get some idea of the types of sounds and effects that can be created with Plate the Plate algorithm, be sure to listen to and experiment with presets built on this algorithm. (See Chapter 5: The Presets.) The Plate algorithm is a reverb simulator that produces reverb effects with the characteristic sound of metal-plate reverberators.

    The Algorithms To get some idea of the types of sounds and effects that can be created with the Chorus Delay Chorus Delay algorithm, be sure to listen to and experiment with presets built on this algorithm. (See Chapter 5: The Presets.) The Chorus Delay algorithm is a six voice chorus configured as three stereo pairs.

Also the base delay setting for the Delay 2 and Delay 3. When creating effects with multiple delay settings, use Delay 1 to set the shortest delay.

  • Page 39: Creating Sounds And Effects

    Creating Sounds and Effects The presets in the LXP-15 provide you with a wide range of sounds and effects which you can use right out of the box. You can create new sounds simply by calling up one of these presets and experimenting with the parameters until you get a sound that you like.
  • Page 40 Careful use of slap echoes can increase the rhythmic density and spatial interest of a musical arrangement. The "Tempo" patch source of the LXP-15 can be used to automatically synchronize slap rhythms to a wide range of MIDI tempos.
  • Page 41 There are many possible variations of the chorusing effect; some shade into flanging, or doubling, or even echo. The LXP-15 provides a Chorus Delay algorithm which allows all of these variations. Originally, flanging effects were created by simultaneously playing two identical Flanging programs on two tape recorders.
  • Page 42 Gating allows you to cut off reverberation at any point before its natural decay time — which is in itself a dramatic effect. The LXP-15 has a Gate algorithm dedicated to these effects.
  • Page 43 20 milliseconds later from the auxiliary speaker (like the delay towers near the middle of the audience at a large rock concert). The LXP-15 can provide two delay paths for two zones of auxiliary speakers by using the stereo delay in the Pitch/Delay algorithm.

  • Page 44: Patching

    Patching, as described previously, is the ability to assign a control ( Source ) to Patching any LXP-15 parameter ( Destination ). This allows you to alter the value of the parameter by manipulating the control Source. For example, you can use a foot pedal as a Source and ouput level as a Destination.

  • Page 48 LXP-15 Owner's Manual Lexicon Slider Sources correspond to some type of slider, pedal or wheel on the MIDI MIDI Sliders instrument. The output is determined by the physical position of the slider or wheel. Most sliders and wheels are implemented as unidirectional controllers.

  • Page 51: Global And General Purpose Patches

    Creating Sounds and Effects There are two types of patches possible on the LXP-15: Global patches and Global and General General Purpose patches. Global patches, accessed by turning PAGE to Purpose Patches “Global,” are simple Source-to-Destination links that are active for all setups. As many as 28 global patches can be active at once.

  • Page 56 LXP-15 Owner's Manual Lexicon When using any of the Note Sources (LastNote, HiNote, LoNote), the threshold value is the Note Number that will correspond to the initial Destination parameter value. (On a standard 5-octave MIDI keyboard, 36 corresponds to the lowest C, 60 is middle C, and 96 is the highest key.) Threshold should be set to a value...
  • Page 57 Creating Sounds and Effects The scale value determines the effective range of the Source controller. For example, a scale value of 50% means that moving the controller through its full range of motion moves the Destination parameter through 50% of its total range. The upper and lower limits of the scale range are determined by the threshold and intial parameter values.
  • Page 58 The General Purpose patching system allows you to customize the response of General Purpose Patches each LXP-15 setup to your requirements. Here are some tips and techniques for getting the most from General Purpose patches. • Fine tune the parameters on the Delay, Pitch/EQ, Reverb, Level, and Mod pages before creating any General Purpose patches for the setup.
