Looking for a particular maxpat

Mark Gustavson's icon

Sometime ago I downloaded a collection of maxpat for study. There is a particular patch that I cannot find on my computer. The patch had two loaded files, one was a section from "Rite of Spring" and the other file was of a drum kit line. In the patch, one could highlight certain sections of either file and then change various parameters . Does this patch sound familiar to anyone? I believe the patch was created by Jean-François Charles.
Thanks.
