Great - looks nice.

simply to avoid the parsing that goes on.

yup - thanks that does look quite straightforward

yes - I started off as an internal so I could call PD code without
duplicating its functionality.
Can someone tell me if there's a way to get the "newest" object from an

I figure that I should carefully look at the S__N and S__X symbols to get a
hang of how they're used.

I was suggesting doing the dynamic patching programmatically... trying to
avoid any duplication of PD internal code and make a clone/array that is
more robust.

I'm glad that these objects have appeared - very useful and nice to avoid
having to script any dynamic patching stuff which always seems like a step
out of the patching paradigm.

As an aside, is it really true that nobody has created an sprintf external
for PD yet?  Now there's a project for this weekend...
