I am sorry that my example did not make justice to my actual code... I already do unchuck everything after using them. But you have pointed me to something interesting, anyway: many of my objects (but not all of them) have an Envelope chucked to a Pan2, which is permanently chucked to dac. I only manage to unchuck my waveforms and/or stk instruments from the Envelope (which is reused everytime). I am gonna try and do things a little differently and then I can give you a more accurate heads up on this subject. Thanks for your support! Em 16/10/2015 13:18, "Michael Heuer" escreveu:

Hello,

I am writing a program that stores a large number of objects in the memory (thousands of), and then calls a "play" method from each one. As it goes playing, RAM usage increases drastically and a weird lag/clicking happens. Is there a possible method to clear memory (perhaps by discarding objects already played) while the script is in execution? Is there any alternative when calling a large number of functions over short periods of time?

For the sake of example, take this lame pseudocode:

class Foo {

int fooX;

float fooY;

int fooZ;

string fooBla; string fooBlu;

fun void set(int x, float y, int z, string bla, string blu) {

x => fooX;

y => fooY;

z => fooZ;

bla => fooBla;

blu => fooBlu;

}

fun void play() {

SinOsc s => Gain g => dac;

if ( x > 2 ) { fooY * x => s.freq; }

else { if ( z < 4 ) { fooY * z => s.freq; } else { fooY => s.freq; } }

0.5 => g.gain;

if ( bla == "fast" ) { 10::ms => now; } else { if ( bla == "slow" ) { 500::ms => now; } else { 200::ms => now; }

You may want to try unchucking from the dac here

s =< g; g =< dac;

See

I haven't seen memory usage slow ChucK down, but connecting too many things to dac sometimes does.

...

}

}

(now imagine a function that sets thousands of Foo objects, stores them into an array and afterwards iterate through said array, calling .play() function for each item. at this point things become *very* slow because of too many objects filling up the memory).

Even using --silent, the script is eventually sluggish because memory still is filled up.

I hope you can point me to the right direction! -- Jean Menezes da Rocha Compositor Professor -- Faculdades Est Mestre e Doutorando em Composição pela Universidade Federal da Bahia
