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);

I'm sorry, of course sine.sync is documented on http://chuck.cs.princeton.edu/doc/program/ugen_full.html#sinosc. But I must admit that I didn't understand the documentation of this feature until now.

As for the gain modulation, I'm still puzzled. There is no way of setting sine.sync in a way that anything chucked into sine will control sine.gain, right?

You can always try to modulate the Oscilator:


SinOsc vibrato => SinOsc sine => dac;
// This will tell sine to take the vibrato input as a modulator of
// it's frequency.
2 => sine.sync;

5 => vibrato.freq;
10 => vibrato.gain;

5::second => now;

Hi guys,

I'm giving a presentation on ChucK tomorrow and I wanted to show off
some of the basic features in a live coding session. I found that
creating a vibrato (modulating the frequency) is far too hard. The
example I'm looking at is
http://chuck.cs.princeton.edu/doc/examples/basic/whirl.ck. In an
infinite loop, you have this code:

    30 + ( Math.sin(t) + 1.0 ) * 10000.0 => s.sfreq;
    t + .004 => t;

Here, t is a float and s is a SinOsc. Now, what I would have expected is
the following, more intuitive setup outside the loop:

30 + SinOsc freq_mod => s.freq;
1 => freq_mod.freq;

I know that the first line with the "30 + SinOsc" is probably nonsense
in itself, but I could work around that (by using a step UGen for
example). My actual problem is that you can't chuck a SinOsc into s.freq.
Consider this line:

SinOsc freq_mod => s.freq;

I get an error like this:
arguments type(s) do not match:
... for function 'SinOsc.freq(...)' ...
...(please check the argument types)

Is this something that the language is simply not capable of or am I
doing something wrong?

Best, Manuel
