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?

Don't do this.

If you want to reuse it, make it a LADSPA plugin, but don't use Jack for a video game. It introduces complexities that many of your users will not want to put up with, and none of the benefits of using Jack are applicable to (virtually) any video game.

You want either something relatively simple or an API designed for the kinds of needs your game has (or both.)
