Personally I use RRADical in my patches. It is more powerful and
mature compared to [sssad]. Expecially switching between presets on
the fly works flawlessly in RRADical, but it's tricky to do with
[sssad] and only pure-Pd objects currently. [sssad] however
deliberately is kept very simple and small. For example while the core
of RRADical/Memento is three abstractions - [commun], [originator] and
[careGUI] -  [sssad] is just a single abstraction (using some helper
patches inside). 

So if you're stuck with plain Pd, you cannot use Memento currently,
but using [sssad] will make it easy to "upgrade" later. [sssad] is
very similar to [commun] and with some search and replace action it is
possible to replace one with the other: 

All that is needed to convert a sssad abstraction to a RRADical
abstraction is this: [sssad $1/ABC] needs to become [commun /ABC $0]
and one needs to add an [originator $1 $0], that's all.

In theory the other way around works as well, but of course one looses
functionality.

For polyphony a good trick with both Memento and sssad is to use
abstractions that share the same $1-tagname. Attached is a little
example with sssad.

Ciao
