MORPH KITS
A morph kit is a normal kit that is loaded as morph target. Any kit can be loaded as
a morph target.
Loading
> Press LOAD + MORPH
> Select the preset number of the kit you want to load.
> Push the encoder.
> The morph sound is loaded.
> Please note that you won't hear any change if the morph parameter value is set to
zero.
> Use the morph parameter on the performance page to morph the current kit into
the loaded morph kit.
Saving
You can also save the resulting sounds from morph operations. Just press the
SAVE + MORPH buttons and save the sound as a new kit. Instead of the original
sound, the currently playing mixture of the 2 presets will be saved.
Did you know?
If morphing arbitrary presets is too drastic for you, try modifying your
favourite pattern just a little bit and save it to a new location. Now you
can control all tweaked parameters at once!
SONGS
The process to load and save songs is the same as described for the kits. Just use
the button combo Press LOAD + SONG or SAVE + SONG instead.
PATTERNS
Patterns are a special case as they have no name. Loading and saving is done in
a similar fashion like changing patterns in pattern mode.
Loading
> Press LOAD + PATTERN
> The screen will show “Select Pattern, Current: x”
> Now you can use the SEQUENCER and BAR buttons to select the pattern to load.
> If the sequencer is playing, the new pattern will start after the current pattern
has finished playing.
Saving
> Press SAVE + PATTERN
> The screen will show “Save Pattern, Current: x”
> Now you can use the SEQUENCER and BAR buttons to select where to save the
pattern.
> As soon as you press the SEQUENCER button, the display will show “success!”
and the pattern is saved.
The software for the LXR can be updated using the memory card.
10.1. UPDATE PROCEDURE
> Copy the latest LXR_V2_xxx.img to the root of the SD card.
> Push and hold the encoder button while turning on the device.
> “LXR Bootloader” will pop up in the display.
> The LXR will check if the firmware image is valid and has the proper checksum.
> If the check is passed, the update will be installed.
> Do not turn off the power during installation!
> Once done, the LXR will prompt you to reboot and the new firmware will be
running.
10.2. BOOTLOADER ERROR MESSAGES
> LXR*.img Not Valid!
File doesn’t seem to be a valid firmware file. File header not matching
> LXR*.img Wrong size!
Filesize differs from the size specified in the header. Probably an incomplete
download.
> Wrong Checksum
File corrupted. File content does not match the checksum. Probably a download
error.

This chapter will introduce you to the very basics of drum synthesis. Of course, this
is just a small pointer in the direction of a few classic drum sounds. There are
many more sounds to discover beyond the well-known drum sounds of the
analogue classics. Nonetheless we will mostly focus on generating these, because
they provide a good starting point for further exploration.
11.1. KICKS
The basis of nearly every kick sound is the simple combination of an oscillator and
a decaying envelope modulating its pitch. The first 3 voices are perfect for this!
OSCILLATOR
A good starting point is a sine oscillator with a pitch around 30 to 35.
AMPLITUDE ENVELOPE
To decide how to set up the envelope, let's think about the kick sound. A kick has a
sudden impact, so we want no attack (set to zero) since the sound starts with its
maximum amplitude.
The decay controls the length of the kick sound. For the average kick a decay in
the range 20-30 and a slope around 25 (exponential) gives a nice, not too short, not
too long kick. For those booming 808 kicks you may want to set the decay higher.
PITCH ENVELOPE
To get some 'oooomph' and punch into your sound you need to set up the pitch
envelope.
Try a decay and slope setting similar to the amplitude envelope as a start. All three
parameters, decay, slope and modulation amount, have a great impact on the
sound of the kick.

PROJECT
The process to load and save project is the same as described for the kits. Just
use the button combo Press LOAD + PROJECT or SAVE + PROJECT instead.
Where Projects are special is in regard to the place where they are saved. All
previous datatypes are loaded from and saved to the non persistent RAM region
where the project data is located. Projects however are saved to the memory
card and are the only way to save kits, songs and patterns so they will be
restored after a power cycle. Projects are containers that are a collection of Kits,
Patterns, Songs and settings.
7.5. PATTERN GENERATOR MODE
The pattern generator provides an easy way to generate interesting poly rhythms
on the fly. You just have to set the desired pattern length and the number of
active steps to generate a new pattern using the euclidean algorithm.
