Loop Pedal script - is sound present (or just timing)

I've been using this code for toggling between Rec/Play/Overdub. With Track copy timing, I have to Long-Press the adjacent track to get to Record. If I write the following, I could be overwriting the loop at a later time when full:

if mode == play
record

Is there a way to know if a loop has Sound in it? I'd rather not use up the double click or long press with this condition.
