Almost. I'd use;



index => m.gain;

Note that this sets the amplitude of the osc's output to something far
beyond the normal amplitude. That is desired here, but not the kind of
signal you'd want to listen to directly. For signals we intend to
listen to we'd set it to something between 0 and 1.

yes; http://chuck.cs.princeton.edu/doc/program/ugen_full.html#sinosc

This configures how the SinOsc deals with signals at its input. So;

SinOSc lfo => SinOsc sound => dac; //signal chain

2 => sound.sync; //fm synth

//set amplitude and freq for the lfo here

ok. to continue the above example;

Step centre_freq => sound; //add it to the lfo
440 => centre_freq.next; //set the centre to A4


Relax. All will be fine :-).
