[chuck-users] Heartbeat

I was wondering if it would be possible to use ChucK to script wave files, and I found the answer in one of the "towers of annoy" example -- yes, it's possible. Here's my first ChucK program, which I called "hello_wav.ck": // the sound samples sndbuf my_sample; // load files "wav/Heartbeat Bass.wav" => my_sample.read; // set gain .5 => my_sample.gain; // play my_sample => dac; 3::second => now; It worked just fine. Now, I'd like to play the heartbeat sound "ad infinitum"... I tried this, but it doesn't work: while (1) { my_sample => dac; 3::second => now; } Any ideas?
