Hm, I'm still not clear about how the routing should look like. Maybe
you can give a kind of more formal specification: Assuming you have a
(m,n)-matrix with m rows and n columns. With m=4 and n=3 this will be
printed through mtx_print as: 
  
 matrix:
  0 0 0
  0 0 0
  0 0 0
  0 0 0

A signal~ matrix [mtx_*~] will have m=4 outputs and n=3 inputs then,
that could be selected with the above message matrix. Setting element
(i,j) to 1 will open outlet~ i for inlet~ j then. 

Back to the message patchbay: How should this behave, if you set
element (i, j) to 1? Using the signal analogy I would assume, that all
messages "sent to inlet j" (that is, [list prepend]'ed with j) should
be "sent to outlet i" (that is: the first element of the new list,
which was j, will be set to i so that you can [route] it), but from
your patch it seems you want to achieve something different?

Anyways I attached a message-patchbay which works like I proposed to
illustrate what I mean.

Ciao
