Writing a repeated rhythm

[Loïc Chahine]

Hi all!

I am trying to find a function to simplify repeated rhythm writing. I have a part with many bars like:

r8 c16( c  c c c c) r8 d16( d  d d d d)

and I think it would be easier to write something like:

\myRh { c d }

I found some Snippets, like this one:

or this one:

But they seem not to work with 2.15.42, and I am not able to update them.

Thanks in advance for your help!
