[chuck-users] No simple vibrato example

[Stefan Blixt]

Hm yeah I think you have to do the gain manually. I like to use another
oscillator for modulation like this (dry-coded and untested):

fun void am(SinOsc @osc, SinOsc@ modulator, float modulation) {
    while (true) {
        modulator.last*modulation => osc.gain;
        1::samp => now;
    }
}

SinOsc osc1 => blackhole;
SinOsc osc2 => dac;

spork ~ am(osc1, osc2, 0.1);
