Which is the difference?
Hi. I’m a newbie, so I apologize for this basic question. Which are the differences in between these two constructions? 1. SinOsc s1 => dac; SinOsc s2 => dac; Dn, 2… SinOsc s1 => SinOsc s2 => dac; Thanks. Gabe — Namasté! Sent from Starship iMac27, Captain Battaglia G A B R I E L E . B A T T A G L I A @ G M A I L .

When the chuck operator (=>) is used with UGens like `foo => bar`, it pipes the audio signal from foo into bar. Some UGens accept input (like dac, although dac is maybe more properly an audio sink than a UGen), some produce output (like SinOsc), and some do both (like Gain). I believe oscillators like SinOsc do not accept input, so `SinOsc foo => SinOsc bar` wouldn't make sense. This program produces no audio, for example, at least AFAICT: SinOsc s => SinOsc t => dac; 400 => s.freq; 600 => t.freq; 1::day => now; Your first example creates two sine oscillators and sends their output to the dac to play. You'll need to set a frequency for the oscillators and advance time to hear anything, of course: SinOsc s => dac; SinOsc t => dac; 400 => s.freq; 600 => t.freq; 1::day => now; On Sat, Jun 26, 2021 at 9:47 AM Gabriele Battaglia < gabriele.battaglia@gmail.com> wrote:

Minor correction: running a SinOsc as input to another SinOsc is a method
for achieving frequency modulation. There are several examples in the
chuck distro. To do FM, iirc, there is a special "sync" parameter that
when set to 2 triggers this behavior.
Here is the source for basic/fm2.ck
// basic FM synthesis using SinOsc (2 => .sync; also see fm3.ck)
// modulator to carrier
SinOsc m => SinOsc c => dac;
// carrier frequency
440 => c.freq;
// modulator frequency
110 => m.freq;
// index of modulation
300 => m.gain;
// phase modulation is FM synthesis (sync is 2)
2 => c.sync;
// time-loop
while( true ) 1::second => now;

Thank you Curtis and Dana for explanations. Now it’s clear. Where can I read all the other meaning of .sync? If 2 essentially turns one sin to an LFO, what other values different than 2 do? Thanks. Gabe.
Hi Gabriele - there are a number of online documentation sites: https://chuck.cs.princeton.edu/doc/program/ugen_full.html#sinosc (0) sync frequency to input, (1) sync phase to input, (2) fm synth https://archive.flossmanuals.net/chuck/ch033_unit-generators.html https://github.com/cannerycoders/chuckdoc/blob/main/src/program/ugen_basic.m...
