When you started this shitlanguage was not the idea that is should be declarative and not a black box, and now there is so many anal ENTP's in the project that is start to to back to a fucking EMAC synstax?

What the fuck is up with that if you wanted the fucking EMACS syntax you could kept on going with PERL?

And do not come say it has to be like this.

I mean my question/problem is not incredibly deep, so i guess you know the answer to it. It is a question about the scope of output, and what the syntax is to make the midiaccess thingy global. Because it sure is global in some browsers. But somewhere on the way some ENTP guy decided this needs a little extra parameters... It has to be called in a different manner... You have to instantiate the thing all over.... You probably should read the 10 page manual on howto access the midiobject i wrote....

To make it work you should stand on one leg put a finger in your butthole,"but only after you greased your body with cocoa oil and suck on a lollipop"

Now if you extend text above 10 pages you probably come close to how one initiate the midiobject as global accessible. But the procedures are  written backwards by the ENTP, to conform to first in last out principles. You have to attach the papers to a monowheel and spinn it backwards at 33 rpm to get the instructions to come out in correct order. Then you can parse them and reverse them using a mirror and paperclips. Now you are almost there you just have to backtrack the sum of the parameter calls and add 4 to comply with ENTP prefered checksum compability.

Question 1:
Have you checked that there is a global variable declaration, such as
  var global_thingy;
that is outside *every* function ?

Queston 2:
Have you checked that you do an assignment, such as
  global_thingy = midiaccess_thingy;
somewhere the midiaccess thingy can be accessed ?

If you don't tell us the answer to these questions we will have to
assume that you really, really don't want your code to work.

Yes if my understanding of global variables declared outside functions is correct. The "midi" object is created on success by the web midi api, and then i do "mid=midi". I thought that should be it. mid is declared global see below.

Below is the midiAccess portinitiation "midiportinit.js" file.

var output;var input;var inputs;var outputs;var mid;

if (navigator.requestMIDIAccess) {
    navigator.requestMIDIAccess()
        .then(success, failure);
}

function failure () {
    console.error('No access to your midi devices.'+ + msg )
}

function success (midi) {
    mid=midi;
    inputs = mid.inputs.values();
    console.log("Undefined value?="+inputs[0]);
    // inputs outputs are Iterators
    for (input = inputs.next(); input && !input.done; input = inputs.next()) {
       // each time there is a midi message call the onMIDIMessage function
       input.value.onmidimessage = onMIDIMessage;
    } 
}


function selectPorts(){
   portout = mid.outputs.values();
   portin = mid.inputs.values();
   console.log("Undefined value?="+portin[0]); //outputs undefined 
   console.log("Undefined value?="+portout[0]);  //outputs undefined 
   for (output = portout.next(); output && !output.done; output = portout.next()) {
       var deviceOut = output.value.name;
       //console.log(deviceOut);
       var optout = document.createElement("option");
       optout.text = deviceOut;
       document.getElementById("out_portsel").add(optout);
   }

   for (input = portin.next(); input && !input.done; input = portin.next()) {
           var deviceIn = input.value.name;
           var optin = document.createElement("option");
           optin.text = deviceIn;
           document.getElementById("in_portsel").add(optin);
  } 
}

Well output is the port selected in outputport, you grab it with using get and the index, it is part of the midi object that is created on success of requestMIDIAccess. It is not something that i created i just loop in the values "portnames" so when you send a message it require the port for some reason the port is defined in windows XP and it is definitly read in because it is within the portlist. I am not sure what is going on if it try to reach port before port read in but it should not i have a timeout so the ports available before i continue.

tracknr=1;outportindex=0;programC=16;channelC=1;
var track=[];midiMess=[];t0=0;x=0;textout="";midievent=0;
recordmidi=false;playmidi=false;midimessage=false;
echo=false;clock=0;listTr="";mode="Listen";rs=0;
Rstarttime=0;var output;var input;var inputs;var outputs;

if (navigator.requestMIDIAccess) {
    navigator.requestMIDIAccess()
        .then(success, failure);
}

function failure () {
    console.error('No access to your midi devices.'+ + msg )
}


function success (midi) {
    mid=midi;
    inputs = mid.inputs.values();
    // inputs outputs are Iterators
    for (input = inputs.next(); input && !input.done; input = inputs.next()) {
       // each time there is a midi message call the onMIDIMessage function
       input.value.onmidimessage = onMIDIMessage;
    } 
   
}

function scriptOnload(){
 InitTime= setInterval(init,2400);
}

function selectPorts(){
   portout = mid.outputs.values();
   portin = mid.inputs.values();
   for (output = portout.next(); output && !output.done; output = portout.next()) {
       var deviceOut = output.value.name;
       //console.log(deviceOut);
       var optout = document.createElement("option");
       optout.text = deviceOut;
       document.getElementById("out_portsel").add(optout);
   }

   for (input = portin.next(); input && !input.done; input = portin.next()) {
           var deviceIn = input.value.name;
