Frequency modification in realtime dephases oscillators.

[pedrosanguineti]

Hello,
First of all, thanks for all the hard work. I really like timbre.js.
The issue:

1. Create 2 oscillators (wave:sin, freq:440, mul:0.1, phase:0).
2. Play them.
3. Modify the phase of an oscillator to Math.PI.
   Result: The waves cancel out.
4. Modify the frequency of oscillator 1 to 600.
5. Modify the frequency of oscillator 2 to 600.
   Result: The waves DO NOT cancel out.

Am I missing something?, some physics class maybe?, I think they should cancel out, but they don't.

Thanks,

Cheers.
