This is a really nice synth and a great value if you buy the MHC package (three synths and loads of FX in one money-saving deal). I love it because it has a really distinctive sound. I find that I'm using it more in my compositions. Don't be fooled by the name; this isn't an a-tonal, special FX synth. It's very musical and useful for a variety of contemporary genres. And I love the simple, attractive GUI. Well worth the money if you want something different and not your average Moog/ARP/Oberheim emulator.
[this is an amendment to my earlier review. since it's original posting, i've experienced serious instability with all my MHC synths. i say buy these synths at your own risk, or wait for any serious update news from MHC. all my other plug-ins are performing well, so I know it isn't my system.]
