MIDI Connections

Audio Connections

MIDI connections are dependent on your applications, and on the equipment available in your system. For examples of MIDI system connections, see Chapter 6:

MIDI Operation.

This section outlines several connection possibilities for the LXP-15 II. Because 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-15 II are unbalanced, and should be made with high quality shielded cables with 1/4" tip-sleeve phone jacks at the LXP-15 II end. The connectors must be wired as shown below:

Sleeve - Shield/Ground

Tip - High

Mono or stereo?

If only 1/4" tip-ring-sleeve phone jacks are available, they must be wired as shown:

Sleeve - Shield/Ground

Tip - High

Ring - Connect to Sleeve

The LXP-15 II produces wonderful stereo effects from either mono or stereo signal sources. For mono sources, use either of the two input connectors; the dry signal appears (along with the stereo effects) in mono at both output connectors. For instruments and sources with stereo outputs, use both inputs. We recommend using both LXP-15 II outputs whenever possible but, if mono output is required, you can use just one of the two output connectors. When only one output is used, the left and right signals are summed internally.

Some of the examples on the following pages use stereo instruments and amplification systems, others use mono. Feel free to adapt the examples to your specific requirements.

If you will be using an LXP-15 II as your primary effects unit, and your system includes a console with one or more auxiliary (effects) sends, connect the LXP15 II as shown above. In most applications, it is preferable to connect the LXP15 II outputs to two of the console's input channel strips, panned full left and right, rather than the effects returns. This allows the greatest flexibility in routing and equalization.

In this configuration the console controls are used to set the amount of effect heard—the LXP-15 II program's MIX control should be set to 100% wet.

In some applications (such as when an LXP-15 II is used for a single instrument) it may be desirable to patch the LXP-15 II between the instrument and console. This makes it possible to keep the LXP-15 II up on stage with other MIDI gear, rather than in the console effects rack, making MIDI control much easier.

Set the LXP-15 II MIX control to approximately 50%.

For a very spacious guitar sound, connect the LXP-15 II between a guitar and two amp and speaker stacks. Set the LXP-15 II 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 II also affects the quantity and quality of your distortion. If you use a separate distortion box, you can get around this problem by connecting it before the LXP-15 II. If you prefer amplifier-generated distortion, try the setup shown on the next page.

If you use overdrive distortion, it's usually better to create the overdrive

before

sending the signal to the LXP-15 II to ensure that the effects don't change the quantity and quality of your distortion. In this setup, you need a guitar preamplifier or a guitar amp with a direct output. Feed this signal to either of the LXP-15 II inputs, and then on to a stereo power amp or a pair of guitar amps. (A few guitar amplifiers become unhappy if they are operated without speakers connected. Consult the amp manufacturer for details.)

You can use the effects send and return connectors on a mono guitar amp to obtain similar results. Adjust the LXP-15 II output level so that the amp produces the same output with the LXP-15 II as it does without it.

Setting Audio Levels

The wide range of adjustment available with the LXP-15 II INPUT and OUTPUT controls allow it to be used with virtually any kind of equipment found in the studio or on the road.

To set audio levels:

1. Turn the LXP-15 II INPUT and OUTPUT controls all the way down (fully counterclockwise).

2. Set the instrument output, preamp output, or effects send that feeds the LXP-15 II input(s) to a nominal level. With an instrument, this should be your loudest normal playing level; with a preamp output or console, adjust the output(s) or effects send(s) to produce the highest level possible with the least amount of noise. 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 II, 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. This ensures the best possible signal-to-noise ratio and dynamic range.

In general, it is best to set the gains in your system so that the nominal input to the LXP-15 II is at least 12dB from the maximum converter (peak) level.

Front Panel Operation

If you want to keep this modified preset as a new setup, it is a good idea to assign it a new name before storing it. To change the name of a setup, turn PAGE to "Name". The following display will appear.

Preset # Name Edit: Bright Hall

<Char Char> - - -

Note that the first letter of the current setup name is underlined by a cursor, indicating that it is selected. Turning the ADJUST knob allows you to replace this character with the first letter of the name you want. The ADJUST knob dials sequentially through a list of alphanumeric characters in the following order: (space), 0-9, A-Z, a-z, and an assortment of standard symbols. Pressing the buttons under "<Char" and "Char>" will step the cursor to the left and right, allowing you to choose the characters you want to change.

After creating a new sound, and assigning it a name, you may want to save it for future use in one of the LXP-15 II's 128 registers. — 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. (We have provided a chart for you to record your own program entries at the end of this manual.)

Storing a new sound

To store a setup, turn PAGE to "Store". The following display will appear.

Store into Registr XX Briter Hall ?

Reg # - - - Store

If the register shown on the top line of the display contains a setup you want to keep, select "Reg #" and turn ADJUST to a register you don't mind overwriting. When the display shows the register you want, simply press the button beneath "Store". Successful storage is indicated by the following display:

Stored Registr XX Briter Hall

Reg # - - - Store

Note: The LXP-15 II will not perform a store instruction if memory write-protect

is enabled (see next page), or if you accidentally try to store into a Preset location.

To recall a register, simply turn PAGE to "Setup", select "Registr" and dial the ADUST knob to the register you want. The setup is automatically recalled and ADJUST may be used to modify the sound. (For footswitch control of setup changes, see Chapter 4:

Selecting "Mem Prot" in System Parameter mode allows you to choose ON or OFF with the ADJUST knob.

This feature allows you to choose continual display update of patched parameter values (ON), or display of only the base values of patched parameters (OFF). See Chapter 4:

for details on patched parameters.

Note: Selection of Display Update ON will slow down the operation of the LXP15 considerably. It is primarily useful when

setting up

patches, after which it is

recommended that it be turned OFF.

The LXP-15 II contains five effects algorithms: Delay/Reverb, Pitch/Delay, Gate,

Plate, and Chorus Delay. When a preset or register is loaded, its algorithm is shown in the top line of the display. (See Chapter 5:

The Presets

for a list of the

algorithms used in each preset.) The algorithm parameters are grouped by function onto five pages: Delay, Pitch

EQ, Reverb, Levels and Mod. This format allows you to find the delay parameters, for example, at the same page and display location in each algorithm. Parameters which are not available in an algorithm are assigned a blank space to maintain this format.

NOTE: You can change the current algorithm by turning the PAGE knob to "Alg" and using ADJUST to select a different algorithm. Be aware that different algorithms have different parameters. Changing algorithms with ADJUST may cause some parameters to be set to undesirable values. For this reason, when you want to work with a different algorithm, select and load a preset or register with the desired algorithm. This ensures that all parameters are set to normal values.

The Algorithms

The general signal flow through the LXP-15 II, as well as the features and parameters of each of the five effects algorithms are described on the folllowing pages.

Input Level: Adjusts the amount of input signal sent into the effects algorithm. This signal is the sum of the left and right inputs, after the front-panel input control.

Mix: Adjusts the mixture of the dry (left and right inputs) and wet (the left and right algorithm outputs) signals sent to the left and right outputs. When set to 0%, only dry signal is present at the outputs. When set to 100%, only wet signal is present at the outputs.

Dry Pan: A pan control for the dry signal. When a mono input source is used, Dry Pan will “move” the sound between the left and right speakers. When a stereo, or two-channel input source is used, Dry Pan will make one channel louder as the other gets softer.

Wet Pan: A pan control for the wet signal. All effects in the LXP-15 II are monoin/stereo-out. Wet Pan will make one effects channel louder as the other gets softer.

Output Level: Adjusts the amount of dry/wet mix sent to the front panel output control.

The Algorithms

To get some idea of the types of sounds and effects that can be created with 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. The glide delay can be smoothly modulated through its entire range with no glitches. While it is being modulated, the glide delay produces pitch shift effects. Increasing delay times will shift the pitch of signals being processed flat; decreasing delay times will shift the pitch sharp. The amount of pitch shift will decrease as the glide delay stabilizes at the new delay time. (There is no pitch shift when the delay has stabilized.) The reverberator is a full-featured room simulator with its own predelay. Its many parameters alllow you to design almost any space you can imagine. One unique feature of this reverberator is infinite reverb: a wash of reverberated sound that sustains forever. (See

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.

When creating patches, Glide Delay is controlled from two patch page parameters. Gldlyhi provides coarse control over the entire delay range for the parameter (0-683ms). Gldly provides fine control over a smaller range (0-

16.1ms). Glide Feedback: A positive feedback loop around Glide Delay. When set to

maximum (100%), it continues to add input signal into the feedback loop. Use feedback for repeating echo effects and to deepen chorus/flanging effects created by modulating Glide Delay.

Delay 2: Reverb predelay following the glide delay. It can provide as much as179ms of additional delay.For setups that use a mix of both the glide delay and reverberator outputs, use Delay 2 to acoustically separate the two effects. Like Glide Delay, Delay 2 is controlled from two patch page parameters. Dly2hi provides coarse control over the entire delay range for the parameter (0-179ms). Dly2 provides fine control over a smaller range (5.04ms ).

HiCut: Adjusts high frequency roll-off for the algorithm. Roll-off is adjustable in 16 steps from flat to 320Hz.

LoCut: Adjusts low frequency roll-off for the algorithm. Roll-off is adjustable in 32 steps from flat to 19Hz.

Decay: Adjusts the reverb time for mid-frequency signals. Becase low frequency reverb time (Bass Multipy) is a multplier of decay time, this parameter acts as a master control for reverb time.

In this algorithm, Decay can be set to produce infinite reverb effects. When set to “Infinit,” sounds in the reverb continue to reverberate, but do not decay. (For a truly infinte reverb effect, all of the reverb page settings must be set appropriately. See

Patching Examples

for an example of this effect.) While decay is set to “Inifnit,” input is locked out of the reverberator. This allows you to play over the reverb wash, and prevents cumulative overloading. Experiment with controlling Decay with MIDI Velocity or the input envelope follower for performance control of this effect.

Treble : Sets the frequency above which sounds decay at a progressively faster rate. When set relatively low, it gives a darker tone to the reverberation, simulating the effect of air absorption in a real hall. Maximum setting gives a flat response through the filter section.

Bass Multiply: Sets the reverb time for low-frequency signals, as a multiplier of the Decay parameter. For example, if Bass Multiply is set to 2X and Decay is set for 2 seconds, the low-frequency reverb time will be 4 seconds. For a naturalsounding hall ambience, values of 1.5X or less are recommended.

3-4

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. The size in meters is roughly equivalent to the longest dimension of the space you are trying to create. Note that changing Size temporarily mutes the outputs.

Diffusion: Controls the degree to which initial echo density increases over time. High settings of Diffusion result in high initial buildup of echo density; low settings cause low initial buildup. Echo density is affected by Size — smaller spaces will sound denser. To enhance percussion, use high settings of Diffusion. For clearer and more natural vocals, mixes and piano music, use low or moderate Diffusion settings.

LFO Rate: Adjusts the rate of the internal Low Frequency Oscillator. Note that in order to hear the effect of changing the LFO Rate, the LFO must first be patched to control some parameter in the algorithm.

Reverb Mix: Adjusts the mix of reverb with glide delay effects. You can listen to the glide delay output without any reverb effects by setting Reverb Mix to 0.

Predelay

To get some idea of the types of sounds and effects that can be created with the Pitch/Delay algorithm, be sure to listen to and experiment with presets built on this algorithm. (See Chapter 5:

The Presets

The Pitch/Delay algorithm allows as many as six simultaneous effects in series: long delay with infinite looping, pitch shift, EQ, stereo delay, reverb, and a panner. Delay L can be fed back through the pitch shifter for cascade effects. Pitch/Delay is very useful for creating complex layered effects for instruments and vocals. For example, you can have filtered echoes, pitch shift chorusing, enhanced stereo spread, and reverb, all at once.

A special feature of this algorithm is loop sampling. The Predelay can be used as a loop sampler controlled by Predelay Feedback. Any Pitch/Delay setup can use the loop sampling feature. Choose a length for Predelay, and set Predelay Feedback to 100% to start recirculation and lock out further input. To precisely cue the end of the loop, set the Mix control to 0% and listen to the input. Once the loop is captured, experiment with changing Predelay to shorten it, or Interval to change its pitch.
