Sorry, in Pd Vanilla it is default-MIDI, not Hardware-Midi...

"HARDWARE-MIDI" is what is listed in Pd-l2ork.  I checked to see
if these weird device numbers manifest themselves there-- instead Pd-l2ork
gives me an error with sane device numbers when switching between midi
apis:
couldn't open MIDI input device 0
couldn't open MIDI output device 0

Well, I was lazy and just did [.combobox current $index], whereas Vanilla's
original code calls a proc and essentially does an [lindex $devlist $index].
Luckily the former gives an explicit error whereas the latter returns empty string.
That means my revised code gets a big red error to the Pd console, and Pd
Vanilla gets an empty button and empty popup menu, plus the "couldn't open
MIDI" error I quoted above.

Ok, thanks.
