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,
Casper




// Sitar

Sitar sit => JCRev r => Echo a => dac;

// gain

.56 => r.gain;

// reverb mix

1.12 => r.mix;

// max delay for echo

1120::ms => a.max;

// set delay for echo

112::ms => a.delay;

// initial effect mix

0.0 => a.mix;





// scale

[ 1,5,6,7,15 ] @=> int scale[];



// loop

while( true ){
    // freq

    
    scale[Math.random2(0,scale.cap()-1)] => int freq;

220.0 * Math.pow( 1.05946, (Math.random2(0,2)*12) + freq ) => sit.freq;
    
    //pluck
    
    Math.random2f( 0.1, 0.9 ) => sit.noteOn;
    
    
    
    //time
    
    Math.random2f( .01, 1000 )::ms => now;
    
    
    
}
