[chuck-users] how do you maipulate an array with rand2()?

[Malik Martin]

hi Spencer thanks for the welcome!
glad to be here.

i was suspecting that might be the case but didnt try it because i did 
some research on the buf.pos
command because i kept getting an error saying the argument has 2 
different types. It turns out that
buf.pos or formally speaking, SndBuf.pos only takes an int type so i 
turned all the values to ints rounded to their
highest value in the one's place.

this worked, but it still output nothing. the patch just works as if the 
array that i made doesn't exist!! here is a copy
 of the patch. but before i post it, would i be able to send patches as 
attatchments
to the mailing-list?(would like to know for future refference)

// the patch
SndBuf buf => dac;

// load the file
"E:\samples\AmenMRZ2-180bpm.wav" => buf.read;

//get number of samples
buf.samples() => int NumOfSamps;
<<<NumOfSamps>>>;

//get length in milliseconds by converting seconds to ms
buf.length() / ms => float length;
<<<length>>>;

// time loop
while( true )
{   
    //1 bar at 180bpm cut into 8ths
    [ 0, 167, 333, 500, 667, 833, 1000, 1166 ] @=> int push[];
    push[Std.rand2(0,7)] => buf.pos;
    1333::ms => now;
}
