FM Synthesis Libraries

I'm thinking about using a realtime FM synth for music and sound effects in my next game. I'd write a library myself, but I don't want to waste my time if there's already something good out there. The thing is, google turned up no results. Am I going to have to get cracking on my own?

Oh well the value is accurate* and the name is appropriate if not ideal.

*: I know some prefer a fixed table with fudged values on the grounds that certain ratios come out better, but a) I hate that and b) the FM engines I've investigated don't do it.
