There's a lot of cruft in it. Attached is the new version, slightly
more ordered.

Okay, I added this now: The first and last masses now are fixed as in
your example patch. This allows for models both fixed and free using
the matrix editor: The "border" of the editor is used to do
connections to "ground" now.

Yes, this would be nice. I think, Thomas Grill's "dyn" external could
be a nice model for this, but I didn't think too deeply about this

If you have seen the Csound scansynth tutorial you might get the idea
of what I'm trying: http://www.csounds.com/scanned/toot/

My matrix editor is modeled after the matrices used in Csoudn to
specify topologies.

I think, in the attached patch I finally got the numbering right.
Tomorrow after sleep I will try to understand what exactly I did. ;)

I would suggest to use "programmer's numbering" starting from 0
throughout the whole system. Any personal preferences put aside: The
outlet/inlet numbering cannot be changed anymore, as it's starting
with 0 everywhere in Pd already, so people probably are used to it
already. The same with arrays/tables. 

So masses and links starting with 0 would feel natural and it would
also make programming easier (for example when using
[until]--[counter] loops. Which reminds me: I should have used
[repeat] more often.)
