fm with feedback

Hello!

Can anyone suggest how to create a simple FM circuit with modulator feedback?

I've come up with this, but the pitch does not remain constant (well that's the whole point, but you know what I mean):

SynthDef("fm_fb", {arg b_freq = 440;
  var chain, freq;
  freq = b_freq + (LocalIn.ar(1) * MouseX.kr(0, 10) * b_freq);
  chain = SinOsc.ar(freq, mul:0.3);
  LocalOut.ar(chain);
  OffsetOut.ar(0, chain);
  //Out.ar(1, SinOsc.ar(b_freq, mul:0.1));
}).play(s);

cheers

Matthew
