Welcome
Thank you for purchasing a CrX4 license or trying the CrX4 demo.
The CrX4 is a sample-based software synthesizer, but no sampler (more
on this soon). It is designed for creating music on your personal computer,
both on Mac and Windows PC.
The CrX4's key features 3 different sample based generators which “eat a
sample” and create some new sound from it. Though you can play back a
sample as it was recorded, this means missing the potential of CrX4. To get
you started and inspire your own creativity CrX4 comes with a selection of
high quality presets in a wide range of styles, an easy-to-use one-page
interface, two user-programmable stereo filters, an enormous range of
processing and modulation options including a powerful arpeggiator, as
well as a sophisticated effects section.
We believe that the CrX4 is an exceptional instrument because of its
unique audio processing capabilities, which result from the fact that we at
LinPlug design most of our audio modules from scratch, sometimes
following paths no one else would even consider. We hope you get a lot of
yet unheard sounds using the CrX4 sample synthesizer and that it
becomes an integral part of your music-making.
The LinPlug team, June 2012

Overview
The CrX4 is a 32 note-polyphonic VST sample-based synthesizer with
some extraordinary features. The instrument includes various Generators,
Filters, Effects and Modulation modules.
The design of the CrX4 can be divided into 4 main sections: Generator,
Filter, Effects and Modulation. Furthermore there are various general
settings, a bank/preset browser and a setup page.
Audio signals are created by a Generator that gets triggered from your host
software (DAW software), which might come from track or being played life
from your MIDI Controller (Keyboard, Guitar etc).
The output of the various Generators can be combined in several ways.
The signals can be mixed together proportionately or the outputs of
Generator 1 and 3 can be used to modulate the frequency or amplitude of
Generators 2 and 4 respectively.
This AM or FM increases the harmonic spectrum of the modulated
Generator producing very interesting, harmonically-rich results. At this point
the signals can also be detuned and thickened using the Spread control.
The output of the Generator section is then routed through the Filter
section, consisting of two individual filters. The filter modifies the harmonic
spectrum of the signal. Each filter includes an envelope for controlling the
filters Cutoff parameter, but other parameters of the filter can be modulated
through the Modulation Matrix.
The filters can be either used in parallel or in serial; when in parallel the
filters output is sent to effects 1 and 2 respectively. When in serial, the
CrX4 User Manual
8
output of filter 1 is send to filter 2 and the output of filter 2 is sent to the
effect 1.
Following the Filter section is the CrX4's Effects section which contains 6
independent effects processors. A wide range effects processors are
available including a three types of delay, a chorus, a phaser, a filter, a
reverb, a flanger, a gate, a stereo enhancer, a parametric EQ and a bitreduction/sample-rate reduction distortion.
Effect 1 is following Filter 1 and Effect 2 is following Filter 2, when the filters
are used in parallel, the output is mixed together and then goes through
Effects 3, 4, 5 and 6 which are in series. When the filters are used in serial,
all effects are processed in serial too.
The Modulation section contains the instrument’s Envelopes, LFOs,
Arpeggiator and Modulation Matrix. At various points throughout the CrX4’s
signal path you can modulate the processing parameters using the various
controls found in the instrument’s Modulation section.
The available modulation include 6 envelopes, 4 LFOs, a Modulation Matrix
“patchbay” and the arpeggiator. Independent from this every MIDI
Controllers can also be used to modulate any of the CrX4’s parameters and
some can control the Modulation Matrix (in example the Modulation
Wheel).

Operation / Controls
The LinPlug CrX4 dials and sliders are operated in a linear manner, so just
move your mouse up/down to modify a control.
Holding down the ALT key while clicking on a control changes the selected
control's value a minimum step upwards (when clicking in the upper half of
the control) or a minimum step downwards (when clicking in the lower half
of the control).
Holding down the CTRL key (Windows) or COMMAND key (Mac) while
clicking on a control sets the control to its default value (e.g. for Volume
controls it sets the control's value to 0 dB).
Holding down the SHIFT key while changing a control's value enables finer
control values to be set.
Double clicking once in a Modulation Matrix slot sets the value of the slot to
0.00. Double clicking in the same slot a second time resets the slot to its
previous value.
All Controls can be controlled using external MIDI messages. To do this you
need to use the LinPlug CrX4's ECS which is described in detail later in this
manual.

User Interface Sections
The user interface of the CrX4 is a major overhaul from its predecessor
CronoX 3. It has been redesigned in order to make using it easier and more
streamlined. A major difference is that all relevant edits are on a single
page now. The idea behind this is to give the user direct access to the
instrument’s most commonly used controls.
The CrX4’s Main panel can be divided into 7 sections:
1. Generator
2. Filter
3. Main (including Glide)
4. Effects
5. Modulation (LFO, Envelopes and Matrix)
6. Arpeggiator
7. Preset Browser
CrX4 User Manual

Generator
The Generator section is located on the upper left of the instrument’s Main
There are two controls, which affect both the upper and lower Generator
simultaneously: The Generator Switch and the Cross-Modulation Switch.
The Generator Switch
The half-round switch on the very left
between the upper and lower part of
the Generator section allows to switch
between the most used Generators 1
and 2 and the less often used
Generators 3 and 4. The large light
indicates which Generators are edited,
while the smaller light indicates when at
least one of the currently not visible
Generators are used. This is giving you
a hint that there is more making up the
sound than is currently visible in the
Generators section.
The Cross-Modulation Switch
The Mix, AM and FM button determine the output destination of Generators
1 and 3 respectively. While we explain it here for Generator 1, the same
applies for Generator 3. When the Mix button is selected the output of
Generators 1 is mixed with the other generators output.
The AM (Amplitude Modulation) setting enables the amplitude of Generator
2 to be modulated by Generator 1. This type of modulation can be used to
produce rich and complex waveforms.
The FM (Frequency Modulation) setting allows the frequency of Generator
2 to be modulated by Generator 1. This type of modulation is great for
producing metallic, bell-like tones.
In case of AM or FM, the Generator 1 is operating in mono, so if a stereo
sample is used in the Loop Sampler Generator as modulation source, then
only the left channel is used.
CrX4 User Manual
12
The Generator Controls
The upper and lower part in this section are apart from the just mentioned
two controls absolutely identical. The respective controls in each Generator
are partly the same and partly depending on the type of Generator used:
Common Controls on Top
Each Generator also has its own On/Off switch located to the left of the
module's menu. If you don’t want to use one of the Generators it's best to
switch it off as this conserves CPU resources.
Next is a Menu which allows to select the generator type. There are 5
different available within the CrX4: Time Sampler, Wavetable Sampler,
Loop Sampler, Oscillator and Noise Oscillator.
Finally there is a Edit Helper Menu which offer functions to copy and paste
one generators settings to a different generator and to init the settings of a
generator.
Common controls on the Left
Each Generator module contains
controls for Semitone, and Cent.
Semitone sets the Generator pitch in
semitones. A wide range covering
multiple octaves up or down is
available: -60 to +60 semitones (thats
-5 to +5 octaves).
Cent sets the oscillator pitch in cents (a
semitone is equal to 100 cents). A
range of -100 to +100 cents is
available.
The Track button determines whether
the Generator tracks the pitch of
incoming note messages. If Track is switched off the frequency of the
Generator depends on the Semitone and Cent settings only and is the
same whatever note is played.
Common controls on the Right
CrX4 User Manual
13
The Volume dial is used to set the output level of the Generator. If the
Generator is being used for either AM or FM then this parameter controls
the intensity of the modulation.
The setting of the Bal (“Filter Balance”) dial determines the proportion of
the signal that is sent to Filter 1 and Filter 2. Turning the dial all the way to
the right sends all of the oscillator's output to Filter 2, while turning it all the
way to the left sends all of the output to Filter 1.
Note that when using AM of FM modulation, this control in Generator 1 (or
Generator 3) is disabled (greyed out).
Generator Spread
Though this parameter is not in all Generators it is in three of them: Time
Sampler, Wavetable and Oscillator.
Spread is the “polyphonic unison” of
CrX4, the detuning of stacked
Generators. The Spread dial is used
to set the degree of detuning. When
moved from the leftmost position the
dial gradually detunes five of the
currently selected Generators to
produce a thick and fat sound. This
does not affect polyphony (however it
does use more CPU resources). The
range is Off (thats 0 cent) to 50 cent.
To make sure you not miss a very
small detuning (when the dial is
almost, but not yet at its leftmost
position), there is a small indicator
light top-right of this dial, which is lit
as soon as all 5 voices are active.
CrX4 User Manual

Time Sampler Generator
The Time Sampler Generator is one of the key features of the CrX4. In
some ways, the Time Sampler Generator is like a conventional sampler:
you load a WAV or AIFF file into the Generator and then trigger it.
It however holds just one sample and there are no velocity splits or key
regions. Although only one sample is used as basic waveform for the Time
Sampler Generator, what you can do with this one sample is unique. You
can time-stretch it in real-time (and this time is available as modulation
destination for dynamic modulation in the matrix!). You can pitch-shift it
without affecting the duration. You can use key tracking to control the Time
parameter, all this is allowing you to create really weird sample-based
sounds!
The Time control enables you to
continuously time-stretch the loaded
sample in real-time. As a result, you
can shorten or lengthen the sample
independently of its pitch. In example,
a value of 133 means that the sample
is 133% of its original length. If it was
originally 3 seconds in duration it
becomes four seconds in duration.
The Range is: 25%...3200%.
Around the Time dial there are marks at 50%, 100% (green), 200, 400, 800
and 1600%
The TimeTrack control enables you to set the duration of the sample
independently of its pitch. Let’s say for example, your sample's root note is
C3 and that it is 4 seconds in duration. What happens to the duration of the
sample when you play a C4 (one octave higher)?
This is where Time Tracking comes into play. If you set the Time Tracking
control to 0, the sample duration remains at 4 seconds. If you set the Time
Tracking control to 100%, the sample duration will be reduced to 2 seconds
(a doubling of the frequency results in a halving of the duration, just as in
the case of a conventional sampler). If you set the control to 50%, the
duration will be about 3 seconds, while with a setting of -100% the sample
is reversed and has a duration of 8 seconds. Range: -100%...100%
The Spread is described in the general Generator description right before
this section.
CrX4 User Manual
15
Next is the Sample Name display, which not only indicates the name of the
used sample, but also has a color coding: When written in white, the
sample is from the CrX4 library (within the Library folder), when it is dark
red it is from outside the Library (thus indicating you need to make sure it is
always available at its current location as CrX4 might else not be able to
relocate it). A light red written sample name indicates that the sample could
not be located. As a guideline it is a good idea to save all presets to the “My
Presets” folder (or another user created folder) within the Library, as this
makes sure your samples are all in the Library and all you need to backup
is the Library (and no other locations).
The Sample control is used for loading and unloading samples. The Load
button (folder symbol) opens a dialog that lets you select a file for loading.
The Previous and Next buttons allow you to traverse a list of samples. The
Clear button (X symbol) is used to remove a sample from the Generator
(thus freeing memory and producing no sound anymore).
The Range controls is used to set the relative start and end point of the
sample. If the first (upper) value is set to 0 the sample starts right from the
file’s original start point. Higher values set the start point towards the end of
the sample. The same applies to the second (lower) value adjusting the
end of the used region of the sample.
The Root control enables you to set the unity note of the loaded sample. If,
for example, you set Root to C1 and play a C2 the sample will be played
one octave above its original frequency. In the case of the Time Sampler
Generator, if you wish to obtain the most natural sound then it's essential
that the sample's root note is set to the same note as the one at which the
sample was initially recorded. Otherwise the Generator will produce
unusual effects. In many cases however, it is precisely these effects that
give the CronoX its interesting and unique sounds.
The Loop switch enables a complete loop of the sample, that is, when it
comes to its end it starts from the begin again. This is aprticular useful with
short samples of when you shorten its time with the Time parameter.
CrX4 User Manual
16
Wavetable Generator
The CrX4's Wavetable Generator module uses a sample to generate a
wavetable. This Generator works “best” with samples which are both
exactly in tune and without gaps (regions of silence). However, it might be
that just something not in tune or with varying pitch results in the most
interesting sound.
The Speed dial determines the
playback speed of the wavetable
where the red marked setting is the
approximate speed of the original
sample. Interesting results are
usually achieved with slower
playback, rather than with faster
playback.
Around the Speed dial there are marks at 25%, 50%, 100% (green), 200,
400, 800 and 1600%. These represent speeds from ¼ of the original speed
(duration) to 16 times the original speed.
The Speed Track dial determines whether the playback speed gets faster
with higher notes (positive tracking) or slower (negative tracking). This can
be used for achieving an effect similar to that found on conventional
samplers where playback gets faster as pitch increases. The range is:
-100%...+100%, so with negative values you can create just reverse the
effect usually found on simple (or older) samplers.
The Spread is described in the general Generator description before this
section.
The Sample control is used for loading and unloading samples. The Load
button (folder symbol) opens a dialog that lets you select a file for loading.
The Previous and Next buttons allow you to traverse the samples within the
folder where you last loaded a sample from.
Attention: When no sample is loaded, the Wavetable generates a sine
wave and thus works like an oscillator with a sine waveform.
The Range controls (located in the low left) enable you to define a fraction
of the sample to be used as a basis for the wavetable. This way you can in
example exclude the begin or end of the sample or narrow the sample
down to only a small part.
CrX4 User Manual
17
The Root control enables you to set the unity note of the loaded sample. If,
for example, you set Center to C2 and play a C3 the sample will be played
one octave above its original frequency. In the case of the Wavetable
Generator, to obtain clean wavetables it's essential that the sample's root
note is set to the same note as the one at which the sample was initially
recorded. Otherwise the Generator will produce more or less rough, harsh
sounds.
Loop Sampler Generator
The CrX4's Loop Sampler Generator is ideally suited to looping samples in
a creative way. The user interface for this Generator is divided into two
parts: the Settings in the generator area and an additional Waveform
window in the lower part of the GUI, which can be opened with the Display
Switch in the Settings.
The Settings in the Generator
window contains the following
controls:
The Sample Filename shows
which sample is currently loaded
(in the active sample slot).
Right below the filename, on the
left is a number which has small
arrows left and right of it. Usually
you will see number 0 here, indicating you work with the first sample slot.
The Loop Sampler however allows to work with many samples, though this
is not the common way of using it. To work with more than one sample you
can here switch through 64 individual sample slots (indexed 0 to 63).
The Load button (folder symbol) opens a dialog that lets you select a file for
loading. The Previous and Next buttons allow you to traverse a list of
samples. Once loaded, the sample’s name is displayed to the right of the
Next button. The Clear button (X symbol) is used to remove a sample from
the Generator.
Below the file controls you find on the left the Start parameter (allowing to
start the sample from a certain point instead of from the beginning) and the
Loop-Points (Start and End), allowing you to define a part of the sample
CrX4 User Manual
18
which is looped. These three parameters can also be adjusted in the
Waveform Display window allowing you to actually see these parameters
right on the loaded sample.
Moreover these three parameter (Start, Loop Start and Loop End) can be
dynamically changed in realtime during playback of the sample. They are
available as “Aux Mod 1” for the Loop Start and “Aux Mod 2” for the Loop
End.
The Root control enables you to set the unity note of the loaded sample. If,
for example, you set Center to C1 and play a C2 the sample will be played
one octave above its original frequency. Range: C-2...G8.
The Start, Loop-Start and -End and Root parameters are per Sample, so if
you use more than one sample in this Generator, each sample has its own
settings. The following parameters however, are global for all samples!
The setting of the Release Loop button determines what happens in terms
of sample playback after a note is released. When the Release Loop
button is on, sample playback continues from within the loop even after a
Note Off message is received. This means that the segment of the loop
after Loop-End point never gets played. When the Release Loop button is
off, sample playback ends with the segment of the loop after Loop-End
point.
The Smooth (“Smoothing”) setting determines the degree of loopsmoothing when loop points are used. The maximum setting is 99.9%. A
setting of 50% means that half of the loop's length is used for smoothing.
Depending on the loop length, a setting between 5 and 20% should be
sufficient for smooth loops even with loop points being modulated. It's best
to use higher smoothing settings for shorter loops.
Please note that Smoothing cannot work sufficiently when the loop start
point is the same as the sample start point.
CrX4 User Manual
19
Settings in the Waveform Display
The Waveform Display window shows the currently selected sample as well
as the sample's start point marker (a green vertical line), the loop's start
point marker (a bright red vertical line) and endpoint marker (a darker red
vertical line).
Top left is a small X button to close this window (and showing the LFO and
Arpeggiator edits again).
Next is the control for selecting one of the up to 64 possible samples for
this generator, click and drag the number or use the arrow buttons to move
up or down one sample at a time. Note: most factory presets only use a
single sample, because the CrX4 is not meant to be a conventional
sampler using multi samples in the first place.
Next comes the Filename as well as the controls to browse or clear the
sample. These controls are the same as in the generator edit region.
The Vol (Volume) setting adjusts the volume of the current sample.
The Key Range setting is used to determine which notes trigger a sample.
If you want the Loop Sampler Generator to play more than one sample, use
a different Key Range for each separate sample. In this way you can have
up to sixty-four different samples triggered by different notes within one
Loop Sampler Generator. If you use velocity-split samples the Key for all
samples will be the same, however a different velocity range (see below)
will trigger each sample.
The Velocity setting determines the velocity range in which a particular
sample is triggered. Setting different velocity ranges for individual samples
allows you to create expressive multisampled instruments that respond
CrX4 User Manual
20
dynamically to MIDI input. If you overlap the velocity ranges (for example,
sample 1 is triggered in the 1 to 80 velocity range while sample 2 is
triggered in the 50 to 127 velocity range) you create what is known as a
velocity crossfade. In the crossover region (50 to 80) the volume of one
sample is successively reduced, while the volume of the other sample is
successively increased until only one sample is heard (below 50 and above
80, in this example). Note: the screenshots in this manual do not visualize
this example, as in CrX4 you always only see one sample at a time.
The most prominent part is the sample display, showing a graphical
representation of the sample. The sample data is drawn in different colors:
dark green represents not-played parts of the sample (which are before the
Start Point). Next is a white sample wave for normal playback and the loop
region drawn in a light green color. Samples behind the loop are agin
shown in white.
To adjust the start and loop point markers click on or near the vertical line
and drag them forth or back. The degree to which the Loop Start and Loop
End can be modulated is adjusted by clicking near the top of the loop's start
point marker (the first, bright red vertical line) and dragging to the right. A
small horizontal rectangle opens, indicating the maximum modulation
range.
The scrollbar at the bottom of the display allows you to scroll the sample
sideways when it is too long to be displayed in the window. This, of course,
depends on the current magnification setting (described a few lines below).
The Reverse setting determines the direction in which the sample is played
