[PD-dev] multichannel signals, preliminary support

[Miller Puckette]

To Pd dev -

I've pushed what I think is working support for multichannel signals.  Many
objects haven't yet been adapted to deal with them, but there are enough to
at least test the concepts: lop~, send~, receive~, and (ugh) clone are
multichannel-aware, and new pack~ and unpack~ objects are provided to
combine and split signal channels.

I've put a couple of example patches on
http://msp.ucsd.edu/tmp/multichannel-tests.tgz
... the interplay between multichannel inlets and outlets and clone
are sometimes amusing.

cheers
Miller
