[PD-dev] sysex/midiin and port numbers

[Miller Puckette]

I'm belatedly looking at this to try to figure out what if any policy is
happening here...

Objects like "noteon" should report MIDI "channel" 1-16 for the first port,
17-32 for the second one, and so on.  The only MIDI input objects that
don't have a channel are the byte-by-byte ones, and so these get an outlet
to specify port.  This should be 1 for the first open MIDI port, etc.

For some damn reason, the MIDI port numbers have started at 2 and not 1,
probably since the dawn of Pd.  I think it's worth fixing this - it's a
bug and I think device numbers have been sliding around so much already
that any notion of port-number compatibility is specious anyhow.

I think thought that I should do this for the upcoming 0.45 and not any
new 0.44 bugfix releases.

cheers
Miller
