Like one of the other reviewers said... *don't* pass this synth up because it looks like an average analog emulation and has the normal features. When I first saw it I almost passed it by cause it seemed like a run of the mill analog emulation. But man does this thing sound incredible!! Download it and try it out. The presets (especially the pads) are excellent and really show off this synth. The effect section, even though it appears deceptively simple, is very nice and lets you achieve regular effects such as delay and chorus as well as some really weird stuff. Above all though thing is VERY stable (not a single glitch yet) and uses a VERY small amount of CPU resources (5-7% on most presets). I purchased this synth and am very happy with it (Note that the demo has a beep tone every few seconds). I gave the "features" a rating of six only because there are synths out there that have plenty more features. But again, the sound is a major factor and this synths got it.
**EDIT - Increased feature rating and User interface to 8 with the new Version 2 of Exciton. Still using this synth after all this time. Pretty much my most used VSTi aside of Battery which I use in every song for drums.
