I actually have some simple tap tempo help patches that may be easier than digging through the delay. I think there's also some stuff by others in the community objects.
Here's mine, one gives a pulse based on the average tap input. The other creates a division based on the tap. For example you could have a trigger running at 16ths based on you tapping 1/4s, etc.
