That comes from a combination of the vagueness of the Pd help file ("-midiindev
... -- midi in device list; e.g., "1,3" for first and third" -mididev uses
same syntax) and some possibly outdated info found elsewhere that may or may
not have to do with changes made to the startup flags over the course of Pd
development. That info suggested that the second variable after the comma may
have had something to do with designating the platform-specific midi system
port number or somesuch, but with alsa it's just a single port that gets
dynamically switched so it's always zero. As I said, that syntax will create
16 I/O ports, it's just that Pd also interprets everything after the "1,0" as a
filename as well.

You are correct in that that string will not produce the errors.
However, you missed the 10, so that only produces 15. Upon inserting the 10
and experimenting further I find that it actually doesn't matter what numerals
you give it (they can all be zeros or anything) as long as there are 16 of them
separated by commas. At least, that's the way it is with Linux and Alsa. It
may be different on the other systems due to the Alsa-specific issues I touched
on above. That is, different besides the fact that Mac/Win can't do more than
9 I/0 ATM anyway...
Thanks thou, at least I don't have to look at those errors any more.
