[PD] Recognizing USB MIDI interfaces on Pd 0.48.1 (Debian 9.5)

[Dan Wilcox]

You can use aconnectgui if you don't want to use qjackctl.

Also, you can use the device name with aconnect. Here's an excerpt of a script I rote to start Pd on my wearable 10 years ago. The trick is that you need to wait until Pd sets up its MIDI ports before trying to connect to them in a script.

echo "rc_starts_pd: strating pd"
pd -rt -nogui -alsa -audiodev 4 -audiobuf 10 -alsamidi $PATCH &

# 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
