Numbers at end of Play strings

[PhilOfPerth]

Thank you.
I think the only piece of all that that I was missing (I am also musically trained) is that a number can be appended to a note to change its length, instead of prepending it with "Ln", and I don't think this is documented in Wiki. It shortens the string by one character, so maybe it should be the preferred way of notation?

Edit: One difference I've just realized, is that the appended version can be used to change the length of single notes, while the Ln will "stick" until changed by another Ln.
