DreamStation DXi2 is a polyphonic analog synthesizer plugin based on DreamStation I.

DreamStation DXi2 utilizes the same techniques featured in the standalone version; physical models of analog circuits, mathematical reproduction of analog oscillators which makes DreamStation DXi2 acting just like real analog synthesizers. You can sweep the pitch smoothly from 20Hz to 20kHz and apply the pulse width modulation without any digital aliasing at all.


  • Subtractive synthesis combined with FM synthesis.
  • 3 oscillators, multimode self oscillating IIR filter, VCA, LFO, user EG for each voice.
  • Available waveforms: sine, triangle, sawtooth, pulse, square, noise.
  • Available filter types: 12dB/Octave Lowpass, Highpass, Bandpass, 24dB/Octave Lowpass and Formant.
  • A maximum of 16 voices polyphony.
  • Linear frequency modulation, Hard synchronization, Ring modulation, Distortion.
  • Supported sampling rates: 11.025kHz, 22.05kHz, 44.1kHz, 48kHz and 96kHz.
  • Supported digital audio resolution: 16 to 32-bits.
  • Internal calculating resolution: 32-bits (with 24-bit mantissa).

2016. Wow. My all time favorite soft synth is still working with Windows 10 (as a VST via 'polac's' awesome dxshell v1.0.4b wrapper). Here are 10 reasons I still love and continue to use this amazing synthesizer:

1) Practically zero CPU usage.
2) Zero aliasing. Seriously - if it does, then I certainly can't hear it and I have ears like a freaking BAT.
3) Best sounding PWM on any softsynth. Period.
4) Tuneable noise wave! Hardly any synthesizer (hardware or software) has this feature. Perfect for video game sounds, percussion and FX.
5) Solid, chunky, fantastic sounding raw oscillators (based on the Commodore 64 SID chip, apparently).
6) Characterful and gutsy sounding filters. Resonance can go from smooth and silky to ear-shreddingly distorted.
7) Separate user envelope to effect PWM, Cutoff, Pitch (osc 1 or 2), FM or AMP.
8) Separate PWM LFO.
9) Separate vibrato LFO (with delayed start - perfect for lead sounds)
10) Key off - a really quick and dirty way of making staccato sounds without having to program/edit note lengths. Lovely.

Sure there are more specialist soft synths available with plenty more bells and whistles, but this is my desert island synth. I can (and have) made entire songs with Dreamstation, including drums. I've also attempted to replace it over the years with 'better' soft synths, but I keep returning when I hear an older track which used Dreamstation.

It's the all rounder synth that nobody should be without and its interface is the most well laid out and simplest of any synth I've ever used.

The best part? It's free. You have nothing to lose and everything to gain by giving this one a try.

LFO Speed mod destinations, and a stereo delay just for the helluvit, and I would have the damn perfect VA


Overall good documentation with an excellent reference section.


I'm not really a preset banger myself, but if i were the type to find a preset to tweak into something more personalized, I would probably be very pleased with the default bank. It is very utilitarian.

Cust. Support

This product has reached the end of its life cycle, therefore there is no official support provided by the developer, yet it has it's own section at the Audio-Simulation forums (the developer). I have never experienced a need to receive customer support for this product, although I am pleased with the developer's support for products that are in active development from Audio-Simulation, especially considering the youth of said product (DreamStion II(the host)).


It's free. Instant 10.


It's never crashed or behaved unpredicably for me. As I've already said its sound is very predicable. So i cannot give any negative marks here.


In short, this synth is a no-nonsense general purpose synth, with a broad sonic potential, and is free.

Dreamstation is a synth meant for the advanced user.

Dreamstation is best described as a "team player" sort of synth. In tandem with effects or layered with other synths it can turn a 'good' sound into something "fantastic and unique."

Intermediate and beginners will NOT get this thing. They will say its boring, dry sound is a waste of sound Etc.

Dreamstation also has a longer than usual learning curve thanks to graphics that are dissimilar enough to make their use initially confusing.

Like most synths practice makes perfect. Eventually the confusing things become so easy you are manipulating sounds faster on Dreamstation than almost any other synth.

What it can do is limited.

It does NOT have onboard effects to pretty up the sounds.

What it does do though it does extremely well!

What you get out of Dreamstation depends on what you are willing to put into it.

For me it is the perfect layering synth. No matter how great a patch is, I've found by layering a couple of patches from Dreamstation into it makes it sound even better.

Its tone melts into the sounds of other synths and makes them sound better.

As time goes by its sound is becoming more and more unique.

Also as time goes by, fewer and fewer people know about this gem.

It's only a matter of time, before it becomes a 'secret' sort of synth used by a few producers to create sonics that no one can identify, but really love because its fresh and new sounding.

Use Dreamstation correctly and you'll be able to make your songs sound stand out in a very crowded environment, because nothing really sounds like Dreamstation.

I've heard a lot of people complain about DreamStation, about this or that, but honestly I don't know why. Nearly every time I need a solid, bread-and-butter VA sound out of a soft synth, I end up using DreamStation. Lots of other VA soft synths have more features and are better at certain things, but none are as flexible and usable as DreamStation.

In particular, I've heard people complain the sound is thin or uninspiring. Frankly, I have no idea what they're talking about. I've gotten tremendous basses and nice pads out of DreamStation. And the brass! Wow, you can get a lovely Vangelis CS80-style brass out of this thing, complete with delayed vibrato.

DreamStation lacks only two things really. First is a mod matrix. DreamStation is a very simple VA model, with hardwired modulation, which limits the diversity of sounds it can make. Again, it makes bread-and-butter stuff wonderfully, but if you need a 'different' sound, you'll have to look elsewhere.

Finally, the UI on it is just too small! The knobs are so tiny that sometimes I have to squint to see them clearly. Not that it isn't a nice UI - it is, and very well designed. If it was about 50% bigger, it would be perfect.

I had a very different support experience than the other reviwers:
I purchased Cakewalk Plasma and received the DreamStation with it. Overall, a very good deal. I wanted to use DreamStation with Fruityloops and was horrified to get an intermittent clicking noise. When I emailed the program author, it took a few weeks but he kindly emailed me the version that was optimized for FruityLoops. I was very pleased with the support as this solved my issue completely. I have also had stuck notes with this synth, but adjusting the polyphony can minimize the problem.

Now for the sound:
It's very analog sounding, but often in a buzzy, aggressive way... I'm not thrilled with the Filter. I recommend never turning the resonance up more than 60% unless you like squealing. For a smoother analog VA subtractive synth I'd have to recommend SimSynth or daAlpha instead. Having said this, I'm still glad I have it in my arsenel. It has an excellent FM knob and a cool 2nd assignable envelope that can be used to alter the FM amount in addition to other destinations. Its random LFO is good to. What irks me most about this synth is that the freestanding version has an exceptionally thick chorus effect that would really smooth out the sound... but they didn't include it in the DXi!

Three things that it excels at:
* hard synced oscillator sweep sounds (ala Gary Newman)
* TB 303 bass simulation
* Small, dark, clinky FM arpeggiator sounds

One thing it sorely needs:
Velocity Sensitivity!
