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 ?
