I bought this plugin (bundled with MuLab) during Black Friday. MUX Modular is very flexible and seems able to build almost any synthesizer or effect. It is easy to use and customize. I started to browse the Community Library, it contains useful examples, thanks to uploaders.

I do not understand why this plugin is almost unknown while it could generate sounds as good as those generated by Reaktor, Hyperion, Zebra, The Grid, MAX4Live, etc.

I tried the demo and I really love it!
if vst3 is not important to you, then it can be just perfect for you!
I think that I will buy it once it will have vst3 support.
I give it 4 stars till it will have vst3 support and then I will probably buy it and give it 5 stars ^_^.

This is by far the best and easiest to use synth I ever have used. Not only can it handle very complex patches, but also, it is very easy to understand and create them even at a beginner level.

I recommend this synth to anyone who can afford it.

*Stellar*. The MIDI routing and management is rock solid and fully flexible. Some complex vsti GUI's do not open properly in other DAW's/environments, or my chain of devices may cause crashes or timing errors in them (many arpeggiators and step sequencers running simultaneously), but MUX never misses a beat. I can develop entire live performance pieces inside a MUX and then open it reliably in any DAW, and it is ready to go. One of my best investments. Thank you MU!!!!!.

The MUX is a VST synth with modular structure that's around for quite some time now but it seems as if it has gone under the radar so far and wasn't recognized much. So why do I give it such high marks though?
Well, apart from being a modular synth (which may sound offputting for some) MUX is quite easy to use and offers the option to assemble your own front panel for a synth with any parameters you like. So you don't have to dig into a jungle of parameters to create a sound. And if you need to go deeper - just open the (resizable) modular area and examine what's under the bonnet.

Since I don't want to bore you by listing the entire feature set of MUX (you may read about that in the manual and on the Mutools website) here are some highlights showing what's unique about it:

  • Standard Oscillator has terrific unison features; much more sophisticated than you would expect from most virtual anlogue classified, non-modular machines.
  • Multiform Oscillator features very complex, but easy to use wavetable synthesis (wavesequencing) and allows the use of sample grains; it's a combination of wavetables and granular synthesis you'll find nowhere else (if I'm wrong, please let me know). You can also analyze you own samples to create new waveforms of them or just draw a new waveform in the waveform window.
  • MUX can be used as an effect plugin (which is not new) but since other VST-plugins can be used inside the modular structure of MUX you can create even complex effect chains (serial or parralel or a combination of both) on one single track of your DAW. And by using the MUX filters you may turn any standard effect into a frequency multiband version. (Please note that this feature was recently introduced in version 3 of Presonus Studio One. And reviewers were raving about that feature. But with the MUX you can get this in any major DAW that supports VST.).
  • Terrific MIDI routing features: For example you can define different keys on your MIDI keyboard to trigger any sound patch (or sample) within a modular structure. You can then switch sounds easily by pressing the desired key. You may even set up keyswitching for different instrument articulations (for example legato, staccato or pizzicato playing) if your standard sampler doesn't support this. (I equipped my Miroslav Philharmonic sampling library with keyswitching and saved a lot of money I had to spent for MP version 2!).
  • You can use any installed VST plugin as a module in the MUX modular structure. Why is this that important? Here's an example: I use Imageline's additive Morphine synth and one of its shortcomings is the lack of standard filter in it's signal chain because it's sound engine is completely additive (except for some effects). But the MUX can cure this: I can couple it with one of the MUX filter modules and I get what I want. Stellar feature.
  • Easy editable front panel - you don't have to be an expert to make your own configuration. And: Any preset can have it's own individual front panel design - matched to the most important tweaking parameters.
  • New paradigm of preset management: Presets are not split between lots of different machines - Sound comes first, not different machines.

So - besides having great functionality - how does it sound? Well, any color you like I'd say: fat, lush, warm or cold digital; it's up to you in the end.

Is it expensive? Well, is 59 Euros too much for such a complete package making lots of other VST stuff obsolete? I know there are some folks out there calling it the bargain of the century.

Will it be supported in the future? The developer is in the business for years (if not decades) now and is one of the most responsive guys here at KVR I've come across so far. He always has an open ear for your problems and wishes and chances are good he will be doing so in the future - if some of us are going to spill some coins into his pockets from time to time.

Is there a demo version available? Yes there is - it's a fully functional version that will let you examine everything in full detail. The demo's just emitting a nag noise from time to time to remind you that MUX isn't freeware.
If you're interested in covering new ground in synth programmimg and/or are willing to learn something about sound synthesis you definitely should give the test drive a spin.

This might just be one of my new favorite VST's!!!! I love the variety of sounds this thing can produce and was surprised at the quality of the massive library of sounds. Wish I would have found this sooner. You will not regret trying or buying this instrument.

What a pity - only for PC.... I'd love to work with it....

Well, it's time to get this started then.

If all goes well, MuLab will make the proper splash it should have already and MUX will become a known and popular format, too. With the addition of the MultiForm Oscillator, it really becomes a brilliant and unique synthesizer and new modules are bound to join the ranks. You can easily and visually create patches that otherwise would require complicated scripting or aren't even possible in any other way than with the MUX. I recommend everyone crossing fingers.

Anyway, I'll start posting some patches. I hope, they'll remain compatible with upcoming versions, which is probably one of the most troublesome aspects of the MuLab development as it really might have to do some leaps that complicated backwards compatibility, but I will see that I maintain the patches and update them accordingly. I'll keep it up as long as I can, of course. 8)

The MUX can be everything you want : all kind of synths, samplers, audio effects, MIDI effects, plugins chainer, mixer, and so on.

I think it's the better VST never made, because aside its polymorphism, the sound is BIG .
