Well, each snippet's feature vector would be added as a new database
entry to the leftmost inlet of [timbreID], no? The you'd ask for the
nearest entry at its second inlet.

Yes, your example is not so different from what you see in the
help-patches of that great library.

Have you checked out William's examples, which I can't locate in
original on his web page (seems down) but which have been mirrored here?
