(calling) patch when the parent is saved, that is retrieved when reloaded
from a file.  I don't know of other meanings of "savestate" although the
name does (unfortunately) suggest that it's for object archiving ala
NeXTStep (and I think earlier from Smalltalk).

At first glance "savestate" seemed like it might be related to "state saving," e.g., a core class that provides the hooks necessary to take a "snapshots" at will of system state without requiring the user to prepare the patch for that purpose ahead of time.

That's what the guts looked like when I ported it to Purr Data, but I haven't really used it yet.

I guess that 2 sharing the same preset bank should be fine for most cases. So using a file to load and save inside the abstraction (as it was possible before) was kinda fine. So this is where I start to think I could be compromising my beloved "KISS" principle... but I was already thinking??import/export was nice to allow people to store these things in the patch rather than a file, so it's cool. It's versatile and still simple enough.
