QUICK START
The LXR-02 comes with
a universal wall wart
PSU for worldwide use.
Install the appropriate
adapter on the PSU
and connect the LXR to
a power outlet. Use
cables with 6.3mm
jacks to connect the
main output to the
mixer and start making
beats!
The fastest way to get some beats out of your new box!
> Make sure the SD card is inserted in the LXR
> Power up the synth.
> Press the PLAY button. The chaselight starts running.
> Adjust the volume faders so they are not at zero volume.
> Use the 16 SEQUENCER buttons to activate some steps. Now you should hear the
first voice playing.
> Use the 7 VOICE buttons to change the active track/voice
> Again, use the 16 SEQUENCER buttons to activate some steps. The next voice should
now play as well.
> Press the LOAD + KIT (Step 8) buttons together. You are now in the kit load mode.
> Use the encoder to select another preset. Confirm the selection by pushing the
encoder. This will load a new kit and the sound will change accordingly.
The following image outlines the LXR's data structure.
3MEMORY MANAGEMENT
The LXR operates with all data (Kits, Patterns, Songs etc)
loaded into the internal RAM. The data is loaded from the
SD card during power up. All edits are made to the volatile
copy of the files in RAM. If you power down the LXR
without manually saving the project, all changes will be
lost! Data will only be written back to the SD card for
permanent storage once a PROJECT is saved!

LXR OWNERS MANUAL10
4.1. SD CARD
The memory card is used as non volatile storage. Without a memory
card you are not able to save your work!
4.2. PROJECTS
The LXR can handle 64 projects stored on the SD card. A project
consists of 64 Kits, Patterns and Songs as well as the project setting
files. Projects are created as folders on the memory card.
4.3. KITS
A kit contains the instrument data for the 6 Voices. All synthesis
parameters are stored here. Kits are stored as .SND binary files inside
the Project folder. The factory preset kits are developed by Leoš Hort
aka hrtl.
4.4. PATTERNS
A Project contains 64 Patterns, each with 7 Tracks containing 64 Steps
in 4 Bars. Patterns contain the note and automation data for each
instrument. They are saved as .PAT files inside the project folder.
4.5. SONGS
A Project contains 64 Songs. Each song is a list with up to 64 Patterns
that will be played one after another.
The LXR offers 6 voices. They are optimized for different kinds of drum sounds. The type of
a voice can not be changed. There are 3 drum voices, a subtractive clap/snare voice, an FM
percussion voice and a hi-hat voice. In this chapter a diagram of the synthesis structure is
shown for each voice type, then the parameters are explained. Let's take a closer look at
the voice types.

5.2. SNARE VOICE (VOICE 4)
This voice is good for snare-drum and clap sounds. A noise source and a
pitched oscillator can be mixed. Only the noise source is routed trough the filter.
There is no FM capability on this voice.
5.4 HI-HAT VOICE (6)
The hi-hat voice is nearly identical to the Cymbal voice, but it offers 2 different
decay times for the amplitude envelope. The voice is shared between sequencer
tracks 6 and 7, each using one of the 2 available decay times. This allows for playing
open and closed hi-hats. The closed hat (track 6) will choke the open hat (track 7).
5.3. CYMBAL/CLAP (VOICE 5)
This voice uses a 3 operator FM to generate the sound. The main oscillator is
modulated by 2 modulation oscillators. It's great for metallic and noisy sounds!

LXR OWNERS MANUAL12

UNMUTE ALL TRACKS
To unmute all muted tracks simultaneously, go to performance mode and hold
down the SHIFT button. Now the VOICE buttons will unmute all tracks up to the
selected track.
An example:
SHIFT + VOICE Button 4 = track 1, 2, 3 and 4 will be unmuted.
SHIFT + VOICE Button 7 = all tracks are unmuted.
TRACK LENGTH
There are multiple ways to set the track length
Mixer Page length parameter
The length of a track can be set on the mixer page of the corresponding voice
with the “len” parameter. Tracks can be anywhere from 1 to 64 steps.
Last Step Button
Another way to set the track length is to use the Last Step button.
> Press SHIFT + LAST STEP (seq 14).
> Use the SEQUENCER buttons to select the new last step.
> Use the BAR buttons to select steps above step 16.
> You can also set last step with the encoder.
> You can choose the track for which to edit the last step with the voice buttons.
> SHIFT + double LAST STEP key press enters the page where you can set last
step for all tracks at the same time.
> To exit the LAST STEP page press the VOICE button!
Bar Buttons
You can also use the BAR buttons to change the track length.
SHIFT + BAR UP extends the track length by 16 steps.
SHIFT + BAR DOWN shrinks the track length by 16 steps.
If you want, you can extend the track and copy the step data from steps 1-16 to
the steps 17-32, use COPY + BAR to fill the next bar with the current bar data.
6.2. BARS
A pattern contains up to 4 bars, each with 16 steps. The SEQUENCER buttons only
show 16 steps at a time. To view the next or previous bar, the BAR UP and BAR DOWN
buttons are used. You can also enable bar following in the configure menu with FLW
setting!
6.3. STEPS
There are up to 64 steps per track. Steps can be set/removed using the 16 sequencer
buttons.
6.4. STEP PARAMETERS
Each step has a set of parameters. To edit the step parameters in voice edit mode,
hold down the shift button. The display will now show the step parameter page and
the LED of the selected step will start flashing.
AVAILABLE STEP PARAMETERS
The display shows the following parameters:

Edit automation using the step edit menu
The automation data can also be edited manually.
> Go to the step parameter menu. (step edit mode, blinking voice mode LED).
> Use the encoder to scroll to page 2.
> There you will see:
The manual edit is the only way to assign parameter automations from one track to
another. It is advised to edit the target parameter in edit mode (push encoder), since
only then the full names as well as the destination voice is shown.
CLEAR AUTOMATION DATA
A whole automation track can be cleared.
> Hold down SHIFT and press the COPY/CLEAR button.
> While still holding the SHIFT button, use the encoder to select 'Clear [autom.1/2]?' on
the display.

6.5. AUTOMATION
Parameter values can be recorded to the sequencer steps. Each step can store
2 parameter changes. They affect only a single step and are not processed if
the step is inactive. The modulation targets can be different on every step.
CHOOSING THE ACTIVE AUTOMATION TRACK
Before you start recording parameter changes select the active automation
track. There are 2 automation tracks per voice. You have to select the active
track before you record new data. If data is already present on the active track,
it will be overwritten!
> Hold SHIFT and press the REC button. The record options are shown in the
menu.
> The parameter ("trk") selects the active automation track to which the data
will be recorded.
HOW TO ASSIGN PARAMETER AUTOMATION
There are several ways to assign automation parameters to a step:
Realtime recording
> Activate the recording mode by pressing the REC button. The record LED will
light up.
> While the pattern is playing, tweak some sound parameters using the knobs.
The parameter changes will be recorded to the played steps.
Lock parameter values to a single step using the 4 knobs
You can also assign a parameter change directly to a single step.
> In voice edit mode, hold down the SEQUENCER button.
> The LED of the step starts blinking.
> Use one of the 4 knobs to assign a parameter value to the step.
> Release the SEQUENCER button.
> The changed parameter is now locked to this step.

BASIC PATTERN EDITING
Basic pattern editing is done in VOICE edit mode. Select the track you want to edit
with the VOICE buttons. The step data will be displayed on the 16 sequencer button
LEDs. You can then use the SEQUENCER buttons to set and remove steps.
6.7. COPY SEQUENCER DATA
You can copy the content of one track to another:
> Push and hold the COPY button.
> It’s LED will start flashing.
> Now, while still holding the COPY button, press the VOICE button of the track you
want to copy.
> The voice button will flash, too.
> Now push the target VOICE button of the track you want to copy to.
> All buttons stop flashing and the track is copied to the destination.
> To abort the process, just release the copy button.
6.8. CLEAR SEQUENCER DATA
The sequencer data can be cleared to start over from an empty track or pattern.
CLEAR PATTERN
The whole pattern with all tracks will be cleared.
> Press SHIFT + CLEAR
> Use the encoder to select “clear [pattern]?” on the display.
> Push CLEAR again to confirm or release the SHIFT button to abort.
CLEAR TRACK
To clear a single track in the pattern:
> Use the VOICE buttons to select the track you want to clear.
> Press SHIFT + CLEAR
> Use the encoder to select “clear [track]?” on the display.
> Push CLEAR again to confirm or release the SHIFT button to abort.
There are different modes for different tasks. Voice editing, performance or
generating patterns.
The main modes are accessible with the 4 MODE buttons. Further modes and
menus are available as alternate SHIFT functions on the SEQUENCER buttons.
7.1. VOICE EDIT MODE
The voice edit mode is used to modify the sound parameters and to do basic
pattern editing.

PATTERN EDITING
The 16 SEQUENCER buttons are used to set and remove steps in the selected pattern. Each button
is a 16th note from a 4/4 bar. If a step is set, the LED in the button is lit.
SOUND EDITING
> The 7 VOICE buttons (10) select the active voice, which is indicated by a lit LED.
> The parameters of the voice are divided into several pages which can be selected using the 8
SELECT buttons (12).
> Each voice type has its own set of parameters, but the overall page structure is the same for all
voices.
> Parameters in the display can be edited using the 4 encoders below.
Parameter editing
As an example lets
take a look at the
filter page:
To change the frequency of the filter of voice 3
> Press ' VOICE Button 3' to select the voice.
> Press ' SELECT button 6' to show the filter page.
> Use the first knob to adjust the 'frq' parameter.
CLEAR KIT / INIT SOUND
If you want to start over with a fresh sound, you can use the
‘clear kit’ option.
> Press and hold SHIFT + COPY = CLEAR and use the encoder to
select “Clear [kit]?”
> Confirm the selection by pushing the CLEAR button again.
The kit will now revert back to the init sound.
7.2. STEP (EDIT) MODE
This Mode is used to edit the step parameters volume, note
value and probability as well as automation data. You can enter
the step edit mode by hitting the VOICE button again, when you
are in voice mode. It is indicated by a blinking voice LED.
The VOICE button will toggle between voice and step mode.

7.3. PERFORMANCE MODE
This mode is designed to jam live. You can trigger manual rolls for each voice and access
the morph and global sample rate FX. Voice editing is not possible in this mode.
BASIC PERFORMANCE MENU
In performance mode the display shows a set of 5 parameters.
MANUAL ROLL
The first 7 sequencer buttons trigger a manual roll for each corresponding
voice. The roll rate can be adjusted in the menu using the 'rol' parameter. Rolls
are recorded to the pattern when the recording mode is active.
MORPH
The morph feature allows you to morph from one preset sound to another. You
can load any preset from the SD card as a morph target. The Morph amount
value controls the ratio between the original and the target sound. As the
morph parameter is increased, the current sound is gradually transformed into
the selected morph target sound.
For an explanation how to load a morph target, see the LOAD AND SAVE MODE
section of this chapter.
SHUFFLE
The shuffle function will shift the position of every other 16th note
The original pattern timing looks like this:
7.4 .LOADING AND SAVING
When the LXR is turned on, a project is automatically loaded from the SD card to
the machine's memory.
With increased shuffle every other 16th note is delayed, thus shifted in the
direction of the next 16th note:
x x x xxx x xxx x xxxx x
xxxxxxxxx x x x x x x x
