Check out the UGen doc: http://chuck.cs.princeton.edu/doc/program/ugen_full.html#sinosc The three valid input values for .sync are described there. On Thu, Dec 5, 2013 at 11:54 AM, Manuel Bärenz wrote:

Awesome, thanks a lot! Is this sine.sync documented somewhere? Is it possible to modulate sine.gain as well that way?

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?

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); On Thu, Dec 5, 2013 at 12:01 PM, Manuel Bärenz wrote:

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?

sorry for the incomplete repeat post. I find that multiply mode opens lots of interesting possibilities. The nice thing about chuck is there are often many ways to do the same thing . each with different strengths and weaknesses. On Thursday, December 5, 2013, Steve Morris wrote:

You can combine multiple ugens in a variety of ways. In particular you can multiply the output of two ugens. I'm typing without running so forgive typos please.
