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.
CLICK
The attack sound is an important part of a kick. There is no general rule here. Try
different transient generator settings for various clicks and pops or even slightly
increasing the amplitude attack to give some softer bass drums.
TIPS AND TRICKS
> You can further shape the attack of the sound using the FM oscillator.
> You want even more clicks in the attack? Why not enhance the click with a peak
filter?
11.2. SNARE
The snare is a 2 component sound. There is a tonal part for the drum body and a
noise part for the rattles.
Voice 4 of the LXR is designed with these 2 parts in mind. You have an oscillator for
the tonal part and a noise generator with filter for the noise part. Since in most
cases you want a high-pass filtered noise with an unfiltered drum body, only the
noise generator is routed through the filter.
For most snare sounds you want the noise part to be louder than the tonal part,
so
try setting the mix parameter on the oscillator page to a value of around 100.
TONAL PART
The tonal part is quite similar to the kick but not as pronounced. The typical snare
does not need a loud click, nor that much modulation depth for the pitch envelope.
Additionally, since a snare is smaller than a bass drum, the frequency of the
oscillator has to be higher than on the kick.
NOISE PART
For most cases highpass filtered noise with a moderate resonance setting is
sufficient to get good results.
AMPLITUDE ENVELOPE
We want a sharp percussion sound, so the attack will stay at zero.
For the decay it depends on what kind of snare you are after.
> Longer decay times with a very exponential slope setting as low as 5 to 10 will
give you a short hit sound with a nicely decaying noise tail. The tail acts a little bit
like a room reverb on the perception of the snare sound and gives more natural
results.
> Shorter decay times with a linear or exponential slope will give a very dry, direct
snare.
TIPS AND TRICKS
> Not every snare needs tone and noise. Try using only the tonal part with a high
pitch modulation envelope to get the classy Kraftwerk zap.
11.3. CLAP
A clap sound is made from noise. What's special about a clap, is the fuzzy attack of
the sound. Imagine a few people clapping a rhythm. They will never all clap at
exactly the same time. Each of them will have small variations in their timing, some
will clap a little bit earlier, some a bit later.
AMPLITUDE ENVELOPE
To simulate this behaviour we will use the repeat feature of the amplitude
envelope. To get the classic clap sound, a setting of 3-4 repeats is good. Since the
timing differences for the clap are very small, a short repeat time has to be
chosen. An attack value below 10 is good.
Now you will have a short burst in the beginning of the sound.
For the decay we need an exponential slope. A value below 10 is recommended.
OSCILLATOR
A single white noise oscillator set to its maximum frequency.
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.
