Hi Paolo, hi David, I've replaced the current stencil function with the one from the openLilyLib "frames" module (which has even more capabilities). Here is the result: https://github.com/KlausBlum/Ly-Boxer-Snippet If you like, please feel free to experiment or add further things...
I'll try to send you an invitation to give you full access to that repo. (Never done that before, but I'll find my way...) If anyone else is interested, please send a short message. :-) Cheers, Klaus
