[chuck-users] Chuck-ing SinOsc inputs

What is the predicted effect of: SinOsc s1 => SinOsc s2 => dac; ? I was expecting some form of FM, but instead I'm met with stony silence (*). I understand that the .op parameter controls how the input to a UGen is interpreted, but I don't see any documentation on the effect of chucking to a SinOsc input. If the real answer "go read Ge's thesis", I can handle that, but I was hoping for more instant gratification. Thanks in advance... - Rob (*) Of course, I've also initialized gains and frequencies to reasonable values. The full code is: SinOsc s1 => SinOsc s2 => dac; 330.0 => s1.freq; 1.0 => s1.gain; 440.0 => s2.freq; 1.0 => s2.gain; 1::second => now;
