If you want to do this later, I have a small addition: The [spigot]
stuff turned out to be unnecessary. Triggering the until multiple
times in my patch doesn't change or break anything. I attached a
cleaned up version of the example I did, called "ds-traverse". It
should be possible to use as a drop-in replacement for JInext with the
supplied wrapper called "JInext-dropin.pd", which has exactly the same
interface as your JInext.pd.

No, I don't think so: only float, symbol, array and list are possible
types in struct-definitions.

There is a thread going on about this currently, you should have it in
your mailbox, it's subject is "32bit integer float".

Ciao
