(From the library I was pointed here for "feedback and support")

Sort of tied in with my "Rate detection" thread.

Would this node be useful to me for doing what I want to do?

The description is a bit vague for me to get a good idea if it is or not any use.

Thanks in advance.

If this is related to another thread, maybe post it there or at least link to it to help readers know what you are referring to.

You mention a vague description. Can you be more specific in what node you are asking about? Just sharing the node type doesn't help - mention the node module itself so we don't have to guess, even if it's obvious.
