Issue with javascript and [play~] object

    I have been working on a solution based on the [play~] object. However I have had challenges with "clipping" so I have designed a solution where the aim was to generate an envelope at the beginning and at the end of the playback of the segment. However I have not been able to get this to work using javascript and clipping is still occuring.
    Here is the code: // inlets and outlets inlets = 1; outlets = 1;
    var tskOneFragment;
    function playOneFragment(){
    line1= this.patcher.getnamed("sn_line1"); play1 = this.patcher.getnamed("sn_play1");
    tskOneFragment = new Task(fade, this);
    //----Set line object to 0 line1.message(0,0);
    //----start playback of fragment (play from 300ms to 800ms //and use 500ms on the operation) play1.message("start",300,800,500); //increase envelope to 1 using 20ms on the operation //playback should have started giving a nice fade up line1.message(1,20);
    //----Fade before the fragment ends tskOneFragment.interval = 450; tskOneFragment.repeat(2);
    }
    function fade(){ var iter= arguments.callee.task.iterations; //Need to use iter=2 because task first run is immediate if(iter==2){ //Fade clip should end playback 10ms before fragment playback ends line1.message(0,40); }
    }

      you wont be able to trigger objects at precise time im afraid . JS is not good at time related operations , i would nor rely on this . maybe this is issuing your clicks . can you recreate MAX equivalent circuit of that introduced in JS to prove the difference ? . edit : but im not sure if it is causing your clicks , i cant check your max patch to be sure . im just guessing that JS in an issue as ive experienced it before already ,trying to do similar things .

      I believe the clicks are caused by the fact that the wave might be raw cut using a fragment play - hence I need the envelope. I guess one option would be to create the logic in pure JAVA - do you know if it is possible to use this style in pure JAVA or is it JS only?
      e.g line1= this.patcher.getnamed(“sn_line1″);
