[PD] pd linux doesn't like sharing midi devices

[Antonis Galanopoulos]

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
