Yes, DX200 is FM.

I find that FM lets you program sounds that work well with heavy guitars.
Simply pick any sound and turn up the level of the modulators 'till the sound starts to distort. the result is more interesting then simply running a sound through a distortion effect. Bands like Skinny Puppy and Nine inch nails have been using that simple, but effective method for years. (although they also used fuzzboxes and guitar amps to distort their synths).
By the way I also play guitar and sing.
