[chuck-users] chuck crash

[Scott Hewitt]

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
