Music Dev - CC64 flip switch checking functions - for HISE, kontakt or others

A very nifty little script that demonstrates a flip-switch of a variable upon input of a virtual CC64 input from a midi controller. Only for demoing a way you could use this in a music instrument script for a sustain pedal.

<h2>HISE Pedal switch script - using onController, storing flip-switch variable representing midi CC 64 messages</h2>
<p>The idea here is to set a variable to 0 or 1 based on the input from CC64 values. Because you can use either a normal
sustain pedal or a contiuous controller it´s easy to get an overwhelming amount of messages that may cause errors in 
other parts of the script, like the onNoteOn callback. Setting the flip-switch variable is only interesting once we get a
flipped result. It´s either the opposite of 0 or 1 on every actual state change. To preserve action and attention.</p>

<button onclick="initiateCC()">Initiate CC64 messages run (2 times from 0-127 and back)</button>

var stateOfCC64 = 0; // initialize with 0. Pedal is off. 
var laststateofCC64 = 0; 
var x = 1;
const out = document.getElementById("output");

function onController(cc) { // this would be the onController callback in HISE.

  var messageCC64 = cc;
  
  // by dividing 128 (midi interval) by the incoming midi-CC number we find if it is below 64 (128/2)
  stateOfCC64 = ((128 / messageCC64) > 2) ? 0 : 1; // if splitting results in above 2, its a smaller number than 64, so a 0. Pedal is off. 

  if (stateOfCC64 != laststateofCC64) // to not have to worry about this pedal value if it is not different from the last value. Saves cpu-time in other callbacks.
  {
    laststateofCC64 = stateOfCC64; // use the laststateofCC64 in other parts of the script.
    out.innerText += "input: " + cc + ". state: " + laststateofCC64 + ". ";
