Erica Synths LXR-02 Drum Machine Synthesizer - Manual (Page 9)

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.

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.
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.
