Wusik 4000 & 8000 are new projects by Wusik and WilliamK, done from the ground using modern code and totally cross-platform: Windows and MAC, VST/AU 32 and 64-bits.

But how Wusik 4000 & 8000 works? Is that just a regular Modular system? No, it is not. Wusik 4000 & 8000 has a fixed path of audio, but with a modular wire system for modulations. Audio and Events are dynamic routed in this way:

  • MIDI Modules will process and output Note Events and other MIDI data.
  • Modulation Modules will process modulation information using the above data.
  • Envelopes will be processed using voice-allocation information set by checking which AMP Envelope has free-voices. This voice information is sent to all POLY modules that are processed next.
  • Now we process all Sound Generators.
  • Filters are the next stage, processed in Series. (But we will release Parallel Filter Modules that includes more than one Filter into a single Module that process audio in Parallel instead).
  • Voices are mixed into a single stereo path.
  • Effects are processed.
  • SFX Send to Master is copied so when the Master Layer is processed, it will use this information for the Master Effects.

But if I want to use a Sound Generator, let's say, a Sawtooth OSC, to modulate something but not output its audio? Simple, just set its Volume to zero, as it is not applied into the Module Modulation Output. You can still set the Amount of output you want from the Wire Input and Output, including Min and Max values.

Can I attach multiple cables/wires from one source to another? Yes, as many as you want.

Here are some current specs:

  • Cross Platform: Windows and MAC, 32 and 64-bits.
  • Multi-Format: VST, VST3 and AU. (more formats can be added in the future).
  • Preset Categorized and with Author, Tags, Collection Name, Genre, Description and the possibility of searching for those options. Each preset is a XML file with the .w4kPreset file extension, and includes all information in a single file, so you can also move around files and organize in different folder structures.
  • Open-Source Module SDK. Yes, if you are a coder, you can make your own modules.
  • Nearly unlimited number of layers: each layer has its own settings: volume, pan, number of voices, effects, octave, fine, key-zones, velocity-zones, SFX Send to Master Layer, ... just see the videos for extra details.
  • Keyboard Shortcuts with user selectable modifiers: Alt, Ctrl or Shift. By default we use the Alt+shortcut-key.
  • Layer Unison. (Modules must support this, but ours will always do).
  • Note-Stealing with the option of setting Stealing the Same Note to On/Off. This is handy for Piano sounds, where a new note should always reuse the previous voice when its the same note or a note that is already playing the envelope release stage.
  • Modules can have Custom Graphic areas, see the Oscilloscope and XY Pad.
  • Multi Wire/Cable Patch System. Allows to connect nearly any module (when available) to another module parameter. (Also, when available, some modules don't allow that).
  • Resizeable Interface. You can set the size of the whole interface as needed and modules will auto arrange on the screen. Some areas of the UI are fixed, while others are dynamic.
  • Multi Skin support. Skins are just a bunch of PNG files with a XML file that stores information of how things should be set. So users could even mess around with those files and create sub-versions of skins or even new skins, if they got the skills for it.
  • Selectable DATA Folder. You can move the DATA files anywhere you want, and just place a link of this folder next to the actual plugin files.
  • Selectable Tool Tip Time.
  • Selectable Engine Idle Time.
  • Selectable Oversample option. (Shared by all instances of the plugin) From None to 16 Times Oversample. (optional down sample filter).
  • Selectable Wires Type and Transparency with a Keyboard Shortcut to Hide and Show quickly.
  • Modules can be minimized and hidden. They also have an extra menu for hidden options.
  • Modulation "holes", both Input and Output, have 3 options: Amount, Min and Max.
  • Layer hidden wire system for Pitch and Filter Envelope, and also Vibrato and Tremelo information. This can be used by Envelopes and Sound Generators. EG: Envelope is set to Filter Envelope and in the Filter we have an Env option which will use this information without the need of wires attached. You can still use wires if you want, but this way you connect directly without cluttering the interface with tons of wires. (Specially handy when you have multiple filters using the same Envelope) The Tremolo and Vibrato are Modules that uses those hidden-wires to send information to Sound Generators, but they also have a Menu-Option (click on the Module options) to disable Vibrato and Tremolo if you want.
  • As right now, modules auto-arrange in 3 selectable ways: by type, using the full width of the interface. By type and size, but using only the width required to show all parameters. And finally, by size, using the same settings as the previous option. (You can see this on the videos below).
  • Master Limiter (can be disabled).
  • Modules Templates: you can save a module state. e.g: you create the perfect vibrato effect using the LFO module. Save as a template, and you can load the module with this settings with a single click into any preset/project file.
  • Sample Player supporting the following formats: SFZ, WusikSND, WAV, AIFF and W4kSND (a XML format).

Hi everyone,.

I recently got Wusik 4000 and wanted to let you know what I think about it.

Wusik 4000 is a very hands on synth with a certain rack feeling to it like in Reason,so anyone who ever worked on a real hardware will feel instantly at home here.
If you are looking for a synth who can help you creating punchy bass sounds to soundscapes have a look at this monster.
The system works with multiple layers which can send their sound into a master sfx layer each filled with modules which each have subsets of functions selectable in a drop down menu.
You have a wide variety of Osc to select from which is a huge sonic arsenal analog single, dual and tripple and a unison combo Osc's Digital Sample Osc, Wavetable Osc plus a white noise Osc plenty of sonic weapons here.
You can wire outputs into certain input module to create modulation chains to create extremely complex sounds.
You got several audio manipulating weapons to choose from AR, ADSR, Multi Envelope(for all three amplitude, filter and pitch target choose able), LFO's and sequencer plus and XY pad with those you can create complex audio effects and triggering elements for different parts of the sounds.
Thankfully it is pretty easy to handle as the interface is pretty straightforward and not overloaded with visual eye candy, you can get different visual styles for the interface to fit your mood and needs.
Creating sounds is pretty straight forward and then you can delve into complex landscapes, you want to create morphing soundscapes go ahead and layer them creating pulsing sweeps and choirs drifting into the sounds no problems.
The sample library delivered along offer plenty to start with but as it is Wusik it is not restricted to it, Wusik's creators offer to import more than those and this expands it endlessly.
Regarding the power needed to fuel the beast, yes it can be hefty but you can set the real-time setting low and increase it for the render down so it should be inside most peoples budget.
The bang for the buck you get is awesome as the sound-sources are analog and digital Osc's you can get the best of both world into one sound.
I for my part am looking forward to the extension W8000 will bring to this great concept and can just say that you should consider trying out this beast, it is not expensive but it gives a hell of ride and is somewhere between Reason, Absynth and Reaktor in its capacities and a very valuable tool for me.

Aside from all that the developer is very responsive and fixes problems very quickly not a given with some of the other players sadly.

So all in all a fantastic tool with lots to explore and experiment while it's very usable thumbs up for the Wusik team.

I tried several (modular) synths before. And the more I play around with Wusik 4000 the more I am convinced that this is one of the most advanced and flexible instruments that is available today. For me it appears that it turns out to be a little bit like Photoshop - even though I use it almost daily for almost 20 years, I still discover new possibilities and ways to solve my challenges every day. A kind of ultimate tool that fullfills my need for permanent creativity. :-) Today I would recommend Wusik 4000 not only to musicians and sound designers who know what they do, but also to those who intend to start learning sound design. Its modularity allows you to exactly build the kind of synth that you need to follow your sound design course, if you attend one. And you can build up your own dream synth gradually along the course. Of course it needs some days to get into it, and you cannot assess all of its power and flexibility by just clicking through some presets. It is rather like learning to walk: In the beginning you have to invest some patience to learn how to make some steps, but once you get it, you cannot get enough of it - and suddenly you can go wherever you want to go.

Besides that, you can also use one of the many very usable presets. If you are interested: On Youtube and Soundcloud (links below) you can also find some demonstations for some of the presets.

I use it in Reaper and Renoise on a Windows 8.1 PC without any technical issues or complications. I can even use it with my 25000 Galbanum Architecture wavetables that I initially bought for the Rapture synthesizer.

The only negative statement that I can make at the moment is: It can become very addictive.

The user interface design supports the workflow very well. It's fun to use it. I appreciate the fact that it focuses more on the workflow than on decorative aspects, unlike you can find it in many other producs. The technical support was extraordinary fast and friendly. For questions it seems to be the best place to use the forum here on KVR. The development listens carefully to the suggestions of their users and promises to enhance the product experience in further developments based on user suggestions.

So, in my opinion there is no single reason to hesitate and not to try it. Go, grab the demo, and then buy it! If you really intend to invest 100 $ into a synthesizer, I think Wusik 4000 offers the best value for your money, and even more. I give it 15 out of 10 stars :o)

Useful Links:

To get an impression of its professional sound quality and some of its capabilities, don't forget to have a look at some demos on soundcloud: https://soundcloud.com/william-kalfelz/complete-dream-fast-ambient-electronic.

For a quick start I suggest to watch some of the helpful video tutorials that the developer published on youtube: https://www.youtube.com/channel/UCMHD0en8Ot1m_ozQpM2Kusg.

W4000! The Wusik team, does it again.

From BIG chorused silky synths, DIRTY DnB and Dubstep style type basses to granular and other worldly FX, ARPs and a large number of modules, W4000, should be a standard in every studio.

Preset browser is very easy to use. It also provides the user, a number of details fields for describing your presets, when you save them.

Great work, Wusik.
