In the audio world, Convolution is the process of multiplying two signals together or folding one audio file over the other one. The result is a hybrid of the two original sounds, introducing a whole new world of sound creations.

With Galaxy X, those two sound files are the Sources and the X-Files.

The SOURCES are sample sets especially and exclusively recorded and tweaked for use with FX Convolution. All in all X delivers about 15BG of source material with almost 1000 tonally playable source key instruments, over 2000 Effect Sounds and over 5000 Loops.

The X-FILES are Impulse Responses, specifically created for FX convolution, which shape, twist, filter, reverse, deepen, morph and even destroy and rebuild the source sounds.

By the X-Engine’s X-Files a celeste mutates into a tuning orchestra, a bowed ventilator sinks into the resonances of a piano, a sitar smashes into a clatter of glass, a tonal dance loop arises from a kalimba.

The combination of Sources and X-Files creates trillions of sounds unheard before.



The X-EYE is the center of the X surface. Its color corresponds to the amount of FX-convolution in action.

The great thing about X is that you are always in charge of easily and dynamically changing the amount of FX convolution by simply using the Modulation Wheel or any other midi controller.

This way the final sound of X can be constantly and musically modulated. Listen to your music and decide instantly, how much the Source should be convolved. 


A whole world of DYNAMIC CREATIVITY.


X FILES - Impulse Responses


The X-Files put their mark on the Sources, be it the envelope, the frequency, the position or  tonality and resonance. The kind of effect they achieve always depends on the interaction between Source and X-File. Galaxy X being a virtual instrument featuring both the sources and the convolution files gave us the opportunity to co-ordinate them on each other.

The effect of the X-FILES ranges from filtering the source to shaping, deepening, morphing or completely mutating it.

We have recorded hundreds of 'real' X-Files like instrument resonances, phrases,  'mistreated instruments', voice noises or environmental noises and treated them big time for great effects on the sources.

We sampled different rooms, vintage equipment like tape delays or old turntables, ..... We programmed noises for filtering and shaping the sources or recorded and tweaked different loops for creating tonally playable loops.

We reversed all kind of X-Files for creating reverse effects for every X-Source.



Overall you can choose from over 4000 basic source sounds, which are based on over 16000 samples.

Almost 1000 TONALLY PLAYABLE SOURCES like  bowed mallets and cymbals, piano overtones, waterphone , mini-celesta, synthetic attacks and weirdos, different pianos, plucked and beaten instruments, noises or reversed sounds.

Over 2000 EFFECT SOUNDS such as magic balls, whirling wood, circuit bent noises, scratched cymbals, electronic effects, industrial and machine samples or flute and voice phrases.

Over 5000 exceptional LOOPS such as tongue drum, body percussion, world percussions, tonal loops, chopped loops. vinyl loops and weird ones like Rod Spring Piano or Trembling Chimes.


Galaxy X brings convolution sources and X-Files together into one virtual instrument for the first time. This enabled us to co-ordinate all sounds and aspects of FX convolution into one integrated system with an intuitive, easy, but effective user interface.


The source sounds start in the top triangle of the interface, the Sources section. The Sources can be layered by up to three, already creating a whole bunch of complex sources. These combined source sounds take their way counter-clockwise to the next module.


The Pre-X-Engine prepares the sources for FX-convolution. The source can be distorted, crunched and crushed, resulting in a very different interaction with the X-File. The 'Dirt' Section is followed by either a Groove and Sequence generator or an EQ/Filter section. Contour shapes the signal and Repeat adds filtered echoes, also being convolved afterwards.


The combination of source Sources and Pre-X effects already creates a zillion of complex sounds. But these are only the feed for the beast: the X-Engine.


The X-Engine is the convolution module of X.  This is where you choose your X-File, change its length and tuning, sync it to the host tempo and reverse it, if you choose to do so. The main control is the 'X-Factor', representing the amount of convolution. The 'X-Factor' is always controlled by the Modulation Wheel (unless you choose another controller) and always visualized by the centered X-Eye, so you can always 'keep an eye' on the convolution amount.


At the end, the Post-X-Engine finalizes the Xed sound with a panning automation, Color and Filter control and the final Space module. Behind Space hides another convolution module, but this time exclusively serving for all kinds of reverb, from weird small spaces to the Taj Mahal.

    Why doesn’t the sound stop after releasing a key?

    Think about the convolution X-Engine as reverb. Anything going into the X-Engine triggers the X-File. If the X-File is very short, like the Timbre files, the sound stops according to the volume envelope of the source sound. But if it’s a long X-File, like one of the piano resonance files, the sound continues as long as the X-File lasts.


    How can I shorten the sound?

    In the X-Engine you can either shorten the X-File itself using the ‘X-Size’ knob or shorten its envelope using the X-Time knob.


    How long do the longest X-Files last?

    You can find the longest X-Files in the category ‘Soundscapes’. They are up to 30 seconds long. Among the instrument layers, there’s a category called ‘Hit once and listen’, which uses theses Soundscape X-Files. By hitting one key or single keys one after the other, you can easily build long lasting soundscapes.


    When should I use the ‘Reverse’ button in the X engine?

    The Reverse button reverses the X-File. Any sound going through the X-Engine will be reversed according to the length and the sound of the reversed X-File. This makes Galaxy X the most universal Reverse Instrument on the market. There are also a couple of special Reverse X-Files, which are synced to the tempo. Their musical length is included in their name. So if you use the X-File preset ‘Breathe Up_4 Beats’, you can create a reverse effect on every 4-beat source sound.


    Why is there a separate volume adjustment for ‘X-In’ and ‘X-Out’?

    If you found a good balance between the three sources, but with an overall hot level, you can adjust it with the ‘X-In’ knob before going into the X-Engine. If the interaction between the source sound and the X-File creates big volume changes, for instance when creating special resonances, you can adjust the X-Engine’s output volume, before sending it to the Post-X effects.


    Sometimes there are big level differences between the dry and the X’ed signal. Why is that?

    The result of an interaction between source sound and X-File can be very different. For instance, sending a bass instrument into a thin X-loop will result in a very soft level, because the bass frequencies won’t survive the X-File. On the other hand, the interaction can create strong resonance, leading to a distorted output signal.


    Does Galaxy X use a lot of CPU power?

    Generally, convolution is a CPU intensive sound effect, so a fast computer is recommended. The CPU load depends on the length of the X-File used. The Timbre presets and many of the Gear presets work as filters or EQ, and don’t need much power. But the long X-Files might consume quite a lot CPU power.


    What is the difference between the three instrument layer categories?

    The layer types depend on the source material. X-Keys features multi sampled instruments, which are tonally playable over the whole keyboard.  X-FX is based on all kinds of effect source sounds. And X-Loops presents different source loops. The X-File presets are the same for all the instrument layer types.


    How are the sounds mapped on the keyboard?

    This differs for the three instrument layer types.

    With X-Keys the source sounds are mapped over the whole keyboard and layered over each other.

    With X-FX there are two different types of source presets.  The basic sources have different FX sounds mapped from C3 upwards. The 'Single Sources' use only one sample, which is mapped over the whole keyboard enabling great pitch effects.

    With X loops every source is assigned to one octave of your keyboard:

    Loop source 1 can be played between C2 and B2, loop source 2 between C3 and B3 and loop source 3 between C4 and B4. This way you can layer and play 3 loop sources over each other.


    I want to use an expression pedal instead of the modulation wheel for controlling the X-Factor. How can I change it?

    Right-click on the X-Factor knob, select ‘off’ and choose Midi Controller. Now the X-Factor and the X-Eye will follow the expression pedal.
