Hi Szilveszter, Of course! the envelope's multiply their current input value by the current internal value and send that to their output. Makes perfect sense. Thanks. (Do you know if there's a user editable version of the ChucK manual online somewhere? I think some of the sections in the pdf could be explained more clearly.) 2009/11/26 Szilveszter Tóth :

Hi Tomasz!

The Envelope is what its name suggests: an envelope. You need a signal to be enveloped: a Step UGen may help you:

Step st => Envelope env => SawOsc osc => dac; 3::ms => env.duration; 0 => osc.sync; // (0) sync frequency to input,

1 => st.next;

while(true){   1::second => now;   Std.rand2f(100,300) => env.target; }

Regards, Szilveszter (Hillaby)

I expected that the following code would give a tone that would glide to a new frequency each second. But i think I might be misunderstanding the sync property because i'm not getting any audible output from this. Can anyone explain where i'm going wrong?

Envelope env => SawOsc osc => dac; 3::ms => env.duration; 0 => osc.sync; // (0) sync frequency to input,

while(true){        1::second => now;        Std.rand2f(100,300) => env.target; } _______________________________________________ chuck-users mailing list chuck-users@lists.cs.princeton.edu https://lists.cs.princeton.edu/mailman/listinfo/chuck-users
