hi, The issue is indeed in the for loop with the missing loop control, im not sure if it would ever have worked. When I need infinite loops I prefer while loops so rewritten with a while loop could be //connect a plucked string to the soundcard out StifKarp inst => dac; [0,2,3,1,4,2,6,3,4,4] @=> int mel[]; //sequence data 0 => int i; while(1) { //infinite loop i++; Std.mtof( 48 + mel[i%mel.cap()] ) => inst.freq; //set the note inst.noteOn( 0.5 ); //play a note at half volume 300::ms => now; //compute audio for 0.3 sec } also std and has been changed to Std All the best and Happy New Year all Scott 2010/1/1 Steve M.

Hi,

I've discovered chuck only a few days ago so I'm working through tutorials.  Today I tried the following code from Graham Coleman's tutorial http://www.iua.upf.es/~gcoleman/chuck/tutorial/tutorial.html

//connect a plucked string to the soundcard out StifKarp inst => dac;

[0,2,3,1,4,2,6,3,4,4] @=> int mel[]; //sequence data

for (0=>int i; ; i++) { //infinite loop  std.mtof( 48 + mel[i%mel.cap()] ) => inst.freq; //set the note  inst.noteOn( 0.5 ); //play a note at half volume  300::ms => now; //compute audio for 0.3 sec }

This crashes chuck (v 1.2.1.3) at the "for" loop line.  The code presumably used to work.  Has the language changed or is this a simple bug?

Thanks, -Steve
