Thanks Eric, I'm working on extending the bit width of the C:M ratio value.  I gave it 3 more bits
(because that was easy) and I like having more control (though I don't yet know if adding 3 bits is
enough).  Numbers like 2.50000 and 3.50000 give nice bells, but being able to make the value a tiny
bit more and a tiny bit less using 2 generators makes for some nice interaction in the harmonics. 
The synth's structure also allows microtuning the modulated oscillator so even more beating can happen.
