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!
