Thanks for the comment about editing (previous message in this thread), 
I'm able to do it now :) I start to find pure date interesting...

I don't understand totally your quoted explanation.

... I make drum letters, in NtEd for example.... how can pd grab,

About creating the object box, how do I connect the box to [r $0-hit]?
