I'm looking at new free software synths.
I'd like one with a SuperWave P8, Crystal.
Any suggestions?

Uh, this sounds like a question for Tech Talk. Even then, I'm not sure how much help you'll get. The Music Talk forum is mostly casual discussion of music artists, not about actually playing music. It's a music fans' forum, not one for musicians.

I might be wrong but this is feeling mighty spamish.
