[Stk] How to use Modulate?

[Yonatan Doron]

Hi,

I assume Modulate can be used as a vibrato effect.
I didn't quite understand how to use it?
Suppose I have the following code which generates a sine wave:

for (int i = 0 ; i < BUFFER_LENGTH; i++)
{
       StkFloat sample = sine.tick();
      // do something with the sample...
}

How would I add Modulate here so that it applies vibrato to the sine ?

Thanks in advance,
Yonatan.
