Yeah. I carefully checked it wasn't added prior to posting.

I haven't fund a good enough reason to have write access to the CVS  
repo yet. Maybe nagging is good enough 8-)

Um, they are all nice objects for mapping the interval [0, 1] to [0,  
1] with a bijective map - that maps 0 to 0 and 1 to 1. Indeed. But  
envelopes are rather (this might be a sloppy home-brew definition?) a  
non-injective map from [0,1] to [0,1] that maps {0,1} to 0.

So potential, yes, thanks. I'll see if i can't find time to look into  
it. It's properly just involves changing the map's/expr's a bit.

However I would be surprised if most of the, in digital synthesis,  
commonly just envelops don't float about already. Hence making a  
fairly exhaustive all_about(_curved)_envelopes.pd would be grab to  
the pocket from a few experienced users.

Well. I'll see what i can do with my novice skills.
