hi all I have that problem with pd. What I want to do is control ardour from pd using midi MMC. I have set up a working virtual midi card in my system for that reason. If I start pd first it will open the midi devices it is supposed to open (i.e mididev 1,2,3). I start ardour afterwards but no luck, it cannot open the midi device it is supposed to receive midi because *I think* (and I might be wrong) pd opened it first. Same thing happens if I start ardour first,it will open the midi dev but pd wont be able to open the device ardour is using.
I also had a similar problem with another application called seq24, a few weeks ago.
Does anybody knows what is going on? Is pd using oss for midi I/O?
Any ideas welcome

Yes, Pd is using OSS MIDI (/dev/midi, /dev/midi1, etc.) I'm unaware there's any way to get two applications to share a MIDI device (perhaps ALSA can do this?)

Hi.
With the ALSA sequecer API Antonis wouldn't need to use any MIDI device (physical or virtual). PD could just open one or more sequencer ports and people would connect them with other applications' ports or physical devices.
Here there are some example by Mattias Nagorni:

Pd works fine with the ALSA (raw-)midi devices. With a virtual midi card (snd-virmidi) and a bit of "aconnect"ing one can also use more than one device in Pd and do connections between software. Technically this routing is already done by the alsa sequencer without Pd knowing it.
See my chapter in the Linux-MIDI-Howto.
