# Thank you very much! I forget that the problem of sampled discrete signals is called "foldover", I thought that was "wrapping" like Jamie said. Sorry to keep you busy with my ignorance. (But on the way of investigating my problem, I learned much about controlling objects pricely.)

# Thank you for the info about t3-lib! [t3_metro] object is absolutely what I need. It's period has not a minimum acceptable value like [metro]. Their documentation is a bit awkward, but I figured out how to use it.
