Here's a portion of a startup script I use:
echo "rc_starts_pd: strating pd" pd -rt -nogui -alsa -audiodev 4 -audiobuf 10 -alsamidi $PATCH &
# renice pd for much higher priority renice -10 $(pidof pd)
# wait for pd to initialize KA=$(aconnect -i -o | grep "Pure Data") while [ "$KA" = "" ] do sleep 1 echo "rc_starts_pd: pd alsamidi not ready" KA=$(aconnect -i -o | grep "Pure Data") done echo "rc_starts_pd: pd alsmidi is ready"
# connect the UA-25 midi to Pure Data echo "rc_starts_pd: alsa midi connect 'UA-25' <-> 'Pure Data'" aconnect 'UA-25' 'Pure Data' aconnect 'Pure Data':1 'UA-25':0
# connect the VIEWCON dongle midi to Pure Data echo "rc_starts_pd: alsa midi connect 'VIEWCON..' <-> 'Pure Data'" aconnect 'VIEWCON..' 'Pure Data' aconnect 'Pure Data':1 'VIEWCON..':0
It starts Pd, then waits until the PD midi device is registered with ALSA before trying to connect two Midi devices: UA-25 & VIEWCON..
You could run the script from you ~/.bash_profile which would call it as soon as the user is logged in. I use this:
# do nothing if this is a ssh session if [ "$SSH_CLIENT" != "" ] ; then exit fi
rc_starts_pd
It's important to ignore ssh sessions since, if you're like me, and you want to login to your (wearable) computer via SSH to check something, you don't want to launch a new instance of pd.

Ok, I find a solution :
$ aconnect -i client 0: 'System' [type=noyau] 0 'Timer ' 1 'Announce ' client 14: 'Midi Through' [type=noyau] 0 'Midi Through Port-0' client 20: 'USB Uno MIDI Interface' [type=noyau] 0 'USB Uno MIDI Interface MIDI 1' client 128: 'Pure Data' [type=utilisateur] 1 'Pure Data Midi-Out 1'
$ aconnect -o client 14: 'Midi Through' [type=noyau] 0 'Midi Through Port-0' client 20: 'USB Uno MIDI Interface' [type=noyau] 0 'USB Uno MIDI Interface MIDI 1' client 128: 'Pure Data' [type=utilisateur] 0 'Pure Data Midi-In 1'
then : $ aconnect 128:1 20:0
Now, how can i keep this configuration each time i reboot my laptop ? ++
