"Twist" Music Control

Thanks a lot for pointing me in the right direction. I lacked the knowledge to realize that I don't need a second Bangle.on('twist'). And now I realize my newbie question is quite senseless, because a bit more of "if...else-understanding" gets the job done easily.

So here is the less function-cluttered "app":

////////////////////////////////////////­/////////////////////
//   control music by twist/buttons

let counter = 0; //stores your counted your twists
var tstate = false; //are you ready to count the twists?

function playx() {
  Bluetooth.println(JSON.stringify({t:"mus­ic", n:"play"}));
}

function volu() {
  Bluetooth.println(JSON.stringify({t:"mus­ic", n:"volumeup"}));
}

function vold() {
  Bluetooth.println(JSON.stringify({t:"mus­ic", n:"volumedown"}));
}

function sendCmd() {
  print (counter);
  Bangle.beep(200,3000);
  if (tstate==false && counter>0){
  do {playx(); counter--;}
  while (counter >= 1);
  }
}

function twistctrl() {
  if (tstate==false){
    tstate=true;
    setTimeout('tstate=false',4000);
    setTimeout(sendCmd,4100);
    Bangle.beep(200,3000);
  }
  else{
  if (tstate==true){
  if (counter < 5){
    counter++;
    Bangle.buzz(100,2);
    }
  else {
    counter = 0;
    Bangle.buzz(400);
       }
  }
  }
}

setWatch(volu,BTN1,{repeat:true});
setWatch(vold,BTN3,{repeat:true});
Bangle.on('twist',twistctrl);
setWatch(Bangle.showLauncher, BTN2, {repeat:false,edge:"falling"});
