Re: [PD] How to get a list of midi devices without GUI

hello again,

I found the issue,

with -nogui, the patch is loaded before midisettings are done (like audiosettings) and [mediasettings/midisettings] updates it's own device list on startup or on [device ...( message.

So when the patch is loaded at startup without gui, [mediasettings/midisettings( records 0 mididevices. I have to send a dummy [device ...( message 1sec after loadbang to update the list and then [listdevices( report the right number of devices. Another solution could be to delay the patch loading.

Shouldn't [mediasettings/midisettings] update it's own device lists on [listdevices( message ?

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
