(another) arduino sequencer thread.

also, an idea that came into my mind but it's incorrect and i can't understand why:

// Are we playing or stopping?
    {
  if(digitalRead(10, HIGH)  //If Pin 10 is high i press the control button, then check:
    if (digitalRead((13) == LOW) //if the pin13 is LOW
    {
    digitalWrite(13, HIGH) //then make it HIGH (button pressed)
    }
    if (digitalRead((13) == HIGH) //if the pin13 is HIGH
    {
    digitalWrite(13, LOW) //then release it
    }
    fPlayMode = digitalRead (13);

thanks again!
