[PD] midi-out devices listing

[Lazzaro N. Ciccolella]

I all,
using pd with the GUI if I want to know the midi-out devices in my 
computer I go on
main-menu->Media->MidiSettings
and I can obtain one complete list of devices usable.

How I can obtain this list using pd with the -nopgui opton ?

many thanks
