I have been working with this synth for a few weeks and I must say I’m totally impressed with the sonic palette you can get of it.

The main engine offers 256 partials gives a very detailed resynthesis, however it is heavy on the CPU but you can avoid it by reducing the partial numbers or the polyphony.

The layout of the synth is pretty good designed and you can edit the envelopes and operators very easily.

Filter sections is terribly good, you can combine the filters to get some formant stuff to and adding the new envelope morphing capabilities, exponentially multiplies the possibilities.

The resynthesizer is really good and fast, the wave generation is really handy sometimes.

Effects section is top notch. The built in distortion is especially good, and the layout is easy to modify any parameters quickly.

However there is some cons documentation perfectly describes each part of the synth but it lacks a bit in the additive synthesis explanation. Once you follow the link you start to understand concepts better. Google helped a lot too.

And finally about customer service I must say it’s excellent, every question I had got answered by email in a couple of minutes by George, I’d say he’s trying to do his best.

For the price, this plugin is a must-buy, it features unique characteristics and the price makes it is a real bargain.
