Quering which MIDI device/port is selected for a "midiin"???
Hey guys,
I want to know if there is some message or something I can send to a “midiin” object so I can retrive the selected MIDI device/port on a “message” object.
Thanks!

I’m not aware of such a message. If this is important, then you should probably use midiinfo to get the list of all available ports, feed it into a umenu (say) and then only change ports through that umenu. That way you would be able to keep track.

Yeap, I have donne that way.
The problem is that in case of device disconnection, device/port changes inside the MIDIin and as far as I know there is no way yo know to wich one till you double click on MIDIin (I know that it is the first available port)
I already did an alarm system that holds last selection on a variable, then check device existence 1 time per second, in case of non existence it changes te “umenu” to red, and text to “Alarm”, anyway I thought that may be there could be some way to know automatically wich port was selected after last selection disappeared.
Thanks anyway!

Hey gbravetti – I have the same problem, with a lot of USB hardware that may ‘disappear’ or not be available and who knows where your control signals will end up.
I also ended up with a midiinfo list, matching the required ports and sending an alarm message if the port doesn’t exist.
At initialisation though I create a ‘dummy’ virtual midi port, midi objects are set to this dummy (doesn’t go anywhere) when the actual device they should connect to cannot be found.
You could also use the enable 0/1 command into your midi objects to just switch them off when your port is not found – but (see discussion elsewhere) even though ‘enable 0/1′ works, it’s not documented and may not work in the future.
Finally – I think the midi objects always default to the top one in the list if the port they are ‘set’ to does not exist.
