thanks, but no, 

at least with Pd Vanilla 0.45-4, the right flag is *-listdev* to list all devices (both midi and alsa) in the PD's console.

According to this 10-years old post [1], I can still make a redirection of stderr or read at it.

Another solution, since my problem concern only Linux, is to read the output of `ls /dev/midi* | wc -l` to get a list of mididevices, but this doesn't tell if it's input or output.

I think it's just --listdevices on the command line

Hello, 

I'm wondering how to get a list of midiout devices without GUI.
This has to work without GUI.

I tried [mediasettings/midisettings] but it always report 0 devices (both in and out) when there is no GUI.
i also know the -listdev option to Pd, but this only list devices in console, and I need to proccess the number in the patch.

I observe this on Linux (both Ubuntu 12.04 64bit and Raspbian (kernel 3.10.25+) with pd 0.45-4.
But it seems to be OK on MacOS with pd 0.45-3.

Thanks

Antoine
