Hi, I think you meant to put the frequency generation inside of the loop? 

Also, why don't you add some more steps to your 'scale' array ?

For converting pitches: Std.mtof converts midi-values (ranged 0-128, 69 being A4) to standard tempered scale frequencies, bypassing your need to use Math.pow etc...

You could just do: 69 => Std.mtof => sit.freq

You may want to read the ChucK manual, which covers the basics much better then I could explain in a single email !

Happy chucking,

    Math.random2f( .01, 1000 )::ms => now;
    
    
    
}
