Cameleon 5000 is a very interesting synth - using additive synthesis, and able to import wave files and bitmaps for resynthesis, you can create sounds that would take hours (or be impossible) with other synths.
I compose and play mostly new-age, ambient (light AND dark heh heh), and soundscape. Cameleon excels at producing unusual and complex evolving textures, and after importing various waves from my Hollywood Edge CDs (sound effects, mostly) I'm amazed at Cameleons ability to turn things like metal hits and crowd noises into alien landscapes.
The interface is fairly simple, buttons for each of the four possible voices and various windows and panels that allow you to adjust how (and if) a morph is made between the various voices. Without touching the manual I was able to import waves, make and save voices, and create patches - which is excellent as I'm manual-phobic (lol).
Sound quality is good to excellent - I have no complaints here.
Cameleon comes with a pile of presets (I think 500, I'm still working my way through them all) and there are already user-created banks available if the factory-supplied ones don't float your boat. Most of the presets are musically useful, although depending on your genre (if you have one!) your mileage may vary. The true power of Cameleon is in importing waves and creating your own morphs, I can't go on enough about how much this is a "killer feature". I will note that many of the presets that sound a little thin solo sit extremely well in a mix.
CPU useage on my P4 2.53GHz system is modest on most patches, very acceptable for something of this power. It's rock-stable in my current host of choice (Orion Platinum) as well.
Support is excellent, Ben at Camel seems to live on the KVR-VST Camel Audio forum some days (lol).
Bottom line: an excellent product at an extremely attractive price for all it can do - I purchased Cameleon over a fully-expanded JV1080 because Cameleon could do more!Read Review
