Here a bash script I used to use. You can adapt it for your needs :
#!/bin/bash chemin1=$(dirname "$0")/PH.pd sudo etherwake C8:60:00:2D:48:50 sleep 1 pd -nosleep -noaudio -alsamidi -midiindev 0,1 -midioutdev 0 -open $chemin1 & sleep 1 KA=$(aconnect -i | grep "Pure Data") while [ "$KA" = "" ] do sleep 1 KA=$(aconnect -i | grep "Pure Data") done aconnect 'Pure Data':2 'UM-1':0 sleep 1 aconnect 'UM-1':0 'Pure Data':0 sleep 1 aconnect 'nanoKONTROL':0 'Pure Data':1 echo "//////////Done.//////////"

Hey friends, i have a raspberry pi that executes a bash script on startup. Inside this bash script I want two things to happen.
- start my pd patch
- connect my launchpad mini (connected via usb) to pd using the
aconnect-command
..i think i have to use aconnect because in pd itself i only see alsa midi as a midi device.
At the moment, my bash script only looks like this:
#!/bin/bash
sudo /usr/local/bin/pd -nogui -rt -open /home/pi/Documents/RSP/RSP/myPatch.pd
aconnect 'Pure Data':1 'Launchpad Mini':0
aconnect 'Launchpad Mini':0 'Pure Data':0
The problem is that the aconnect-commands seem to be not executed or executed too early because the virtual midi connections are not made.
The aconnect-commands have to be done after pd is started, so how could I change the script to wait until pd is done loading?
Poor man's solution:
put a 'sleep 5' after starting Pd.
A slightly more advanced way:
while ! aconnect --list | grep "Pure Data"; do sleep 0.1;
Put that after firing up Pd. It continues only after "Pure Data" appears in the list of available MIDI ports.
