Too bad it doesn't work on windows 7. I used to go hard on this synth, then I kinda forgot of it and after that I stumbled on it on my old pc and I was baffled by the fact that i had almost 3k presets for it and a lot of really nice ones. God i would pay even 2 or 3 hundred euros for a win7 version.

I installed this in 1998. My internet friends got hold of a copy and serial number. The serial number didn't work, but--miraculously--I figured out a correct serial number from the wrong one and shared it with everyone. I'd love to use this again, which is how I found this page, but from what people say, it's not going to work with Windows 7. Too bad.

It sounds wonderful. I have both versions 2.0 and 2.1 or 1.20 and 1.21,cant be too sure of the number. You will have to keep an old desktop to run Windows 98 for it to work. To be honest, the very first version sounds much better than the later one which sounds lounder but harsher. I think I am the only holder of this synth in my country of China.
