Proteus VX borrows its internal architecture from its big brother, Emulator X3. Although Proteus VX does not have the extensive editing capabilities of Emulator X3, it does offer 16 continuous controllers for each preset. The 16 controllers allow you to create subtle to radical transformations to the sounds, then save them with the bank.

The included v2.01 Proteus X Composer bank comes with over 1000 presets covering an immense range of sounds from the Proteus 2000 MIDI sound module. In addition, Proteus VX can load any sounds from the Emulator X library, as long as they can be loaded into system RAM (Sample-streaming not supported on Proteus VX).

Proteus VX is not copy protected or card locked like other versions of our instrument and sampling software, and can be used either as a VSTi or in stand-alone mode.


  • 24-bit/192kHz audio playback.
  • Can be used as VSTi or stand-alone (16 channel multi-timbral).
  • Built-in 32-bit floating-point effects with 23 effects algorithms.
  • High Voice Polyphony (system dependent).
  • Drag and drop preset selection.
  • Real-time controllers for all important control points.
  • 54 different filter types including multi-pole resonant filters, phasers, flangers, vocal filters and multi-parameter morphing filters.

Note: Proteus VX tutorial support is not offered for this free download. Very limited technical support is available for basic setup and install issues. Proteus VX will install and function for most users under Windows Vista, but this product is only officially tested and supported for Windows XP.

Not available from Creative any more. Creative have eliminated everything Ensoniq and E-Mu from their site except for a couple of pair of their earphones branded E-Mu. I have placed the Proteus VX and the Emulator X3 in Archive.org as abandonware.

This is really the all-you-need- vst!! But the down side of this VST is 1) it takes about 3 to 5 minutes to save just a small change; and 2) when using this and want to do something else, i need to start up my laptop because there is a problem with the sound and restart will solve that problem. So just go with this amazing vst, but keep others just in case.

Proteus VX is a amazing freeware.

It's a rompler, so you have tons of sounds in it, but you can't import your own samples.
The presets in this VX version are numerous (1024) but you have not access to the synth engine. You can alter the sounds with the 16 midi CC controls.
So you have a simple and easy to use sound module.
If you read KVR forums, you can see that most of the people make their opinion on a synth by listening to the presets. Sometime you wonder why there are so many parameters avalaible on the synths because most of the people don't take time to built their own sounds.

Here you have a huge choice of presets, some are very nice, and usefull, so you will certainly find one that suit your needs, and if you want to make some alteration to the sound, you can do it by using the midi CC controls.

The interface is nice, what I really love is that the 16 midi CC controls are always displayed, so you know what they do at a glance, and then you are encouraged to use the controlers of your midi keyboards.
And you realize that it's a simple and fun way to find new sounds.

I personnally think that the sounds sound great, and it's almost a surprise because it's the old sounds from the hardware proteus modules, I must admit that E-mu has a great savoir-faire in samples based synthesis.

The manuel is really great, it's complete and clear. E-mu guys seem happy to discuss their product and their technology.

Considering that it's free, it's a bargain.

Now, if you read on the E-mu site, you see that this Proteux VX version will not be supported on future operating systems.
Many report crashes on Vista or XP Pro.
So, if you have to change your computer, you will not be able to use this little gem anymore.

So it's my conclusion : use it now, and THANK YOU VERY MUCH E-MU, even if we know that such a product is given for free to bring potential new customers to the compagny in the future.

As a long term lover of Emu Proteus sound I remember how sad I was to lose those sounds when I sold my Proteus 2500, for years I missed that machine and it is no longer available !! When I found out there was a VST with THE SAME presets as my P2500, I was very happy, and when I found out it was FREE, I had to kick myself !!! The VST version actually adds some editing capabilities not available on the hardware unit and the voice stealing is much more efficient than on the hardware box, where I experienced a lot of clipping for multi-voice sequences....

The interface has a very nice librarian and allows sounds to be categorized and previewed, and the 16 midi channel multitimbral editor is perfect, with so many sounds and multitimbral options, you could use just this synth for full productions, which I have in the past for many of my songs using only the Proteus 2500... Looking forward to rendering my old P2500 midi sequences now that I have a sound module that contains the original patches I had thought I lost forever !! Using only the P2500, I wrote the soundtracks to 2 commercial video games, one notably "Maniacal Max: The Maniac With a Cause" - by SD Entertainment. The tracks were all done using only the Proteus 2500 with the stock "composer" banks, which are included in this VST in it's entirety !!

A lot of care and love went into the programming of the original Proteus "Composer" banks and in my ears most of the sounds still sound as fresh and exciting as when I first got them. You simply can't lose with this one, get it then buy all the soundsets with the money you saved !!!

It´s almost shocking that first review on this wonderfull instruments is only few days old.

Proteus stands out in my freeware collection / to be true - not only freeware collection /, it´s sound is something different compared to piles of synthedit/synthmaker creations - lots of great drumkits, guitars, basses, retro-synth sounds - an the collections is really, really big. There are even some great addons on digital sound factory site - like the Filters and Functions pack.

The filters of this Instruments standout too, I´m really sorry, that I can´t load my own samples in it in the free version as that would be something!

I just can´t say a bad word about this synth, and if it has some little quirks, I don´t care for them as the positives overweigh them.

So, grab it, if you´re in need of sounds from the Proteus modules, if you´re into hip-hop, big beat, if you´re searching for some great hits, stabs, basses, or drumkits. You get hundreds of presets, the drumkits are really big - not like the usual 8-16 sounds. You´ll even find yourself recognizing some of the sounds from some great tracks of the past eras.

There are not many freebies as this one - Core Player, Kotakt Player, Independence Free...and Proteus.

I had to give it full marks, as I Love the sound, interface, the presets, I never had any problems with it, the value for money is unbeatable, full documentation is included too, and well, I won´t spoil the full marks giving it 0 for customer support as it´s freebie, so what could I want - and I never needed it.

I installed this software into another drive other than C: and both the VST and the standalone products cannot find the sounds.

How can I fix this.

3 June 2018 at 1:26am

On my computer everything is on the unit D, so I'm in the same context as you.

Let's see with the standalone version. At the bottom left of the window you have three tabs :

  • Sampler.
  • System.
  • Library.

First click on the tab "Library" if you never did it, so that you create your library by the button "Update". Let the scanner search in all your system as it is configured by default for that. Don't worry, it is quite fast.

Once done, you should now see two trees appearing in this "Library" tab:

  • Banks.
  • Presets.

And you're ready.

Now choose a preset and drag&drop it on the GUI. Beware, if you simply click the preset name instead of dragging it... the GUI disappears! To make it appear again, simply click the name Proteux VX which is on blue background at the top of the list, then now make carefully your drag&drop from the preset.

You can use the internal keyboard for your first tests. To make it appear, click on the little button showing a keyboard in the toolbar at the top of the windows.

Play around with this first very short tutorial... then read the excellent PDF help file. Especially starting from the page 27. The PDF help file of Proteus VX is really awesome.

If you don't have the PDF help file, don't hesitate to tell it here.

Is there a method for getting them all to the sampler tab in one move?

3 June 2018 at 9:39pm

Probably. I have never tried.

You don't have the PDF help file ?

Tell me. If you don't have it, I'll upload it.

4 June 2018 at 12:15am

I have the PDF.

I'll read it but I thought it would as simple as Dragging and Dropping them from one Tab to the other.

Might not be possible.

where does one find the free dwnload.

I've downloaded it, but when I open every single exb bank file I downloaded, it always says "This is not a valid EOS or Emulator X bank file." in Proteus VX. I thought I installed Proteus VX just fine but it seems to be a problem in the software itself.

UPDATE: Okay I solved the issue, I ran it as administrator and NOW it opened the bank files just fine?! I never expected that whatsoever....

Thanks for that info - I spent a few hours installing, uninstalling and reinstalling on Windows 11, and couldn't get it to load any soundbanks - same message as in your thread. Ran it as admin and bingo! it works :-) :-).
