This is probably terrible programming practise beyondrepair but this is how i solved it.

function success(midi) {
  mid = midi;
  inputs = mid.inputs.values();
  // inputs outputs are Iterators
  for (input = inputs.next(); input && !input.done; input = inputs.next()) {
    //SEND EACH MIDI INPUT TO OUT
    console.log("going to playup midi message");
    input.value.onmidimessage = onMIDIMessage;
  }
bigtest=onMIDIMessage;
}

mymess = {
  data : [],
};

function playNote(A,B){
synth.NoteOn(143+channelTRX,A,B);
if (recordmidi) {
    clock = performance.now() - Rstarttime;
    clock = clock + rs;
    console.log("Clock="+clock);
    midievent++;
    mymess.data[0]=143+channelTRX;
    mymess.data[1]=A;
    mymess.data[2]=B;
    bigtest(mymess);
   }
}

How would a real programmer done it LoL

Try record from keyboard and drummachine on "different tracks".
