I'm trying to track down a bug in my preferences dialog code for midi.
In Pd Vanilla 0.43: If I choose Media -> Hardware-Midi it brings up a dialog
If I choose Media -> Alsa-Midi it brings up a dialog
If I choose Media -> Hardware-Midi, close the dialog, then choose Media -> Alsa-Midi I get insane device numbers in errors to the Pd console: couldn't open MIDI input device 2054 couldn't open MIDI output device 1836017711 opened 0 MIDI input device(s) and 0 MIDI output device(s).
I suppose to be on the safe side, for both audio and midi I should not assume that devices will be numbered contiguously from 0-n. Still, these weird device numbers will probably cause errors.
Unfortunately I don't have a midi device so I can't test it.

what's "Hardware-Midi"?

If I choose Media -> Hardware-Midi, close the dialog, then choose Media -> Alsa-Midi I get insane device numbers in errors to the Pd console:
i don't see this error with Pd-vanilla. how does the "vanilla" property box handle device numbers differently than yours?

if your "hardware MIDI" device is OSS, you can load a loopback driver to get a software device.

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.
