Can´t connect Pure Data on RPi

Patchbox OS
1

After I disabled the autoconnect from PD to every hardware in my system (by disabling amidiauto) I can not establish any connection from PD on my RPi ZERO with Patchbox OS.

Output from aconnect -l

Does it work if you make the connection using aconnect or aconnectgui manually?

i have line in /etc/rc.local like this

amidiminder -f /etc/amidiminder.rules -C

sudo systemctl restart amidiminder

works ok

it is also important to remember to have in rc.local

#!/bin/sh
and NOT
#!/bin/sh -e ,this way it will abort if aconnect cannot make connection due to the absent device

@Giedrius Manual patching works

@kazeko My /etc/rc.local looks like this

#!/bin/sh
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will “exit 0” on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ “$_IP” ]; then

  • printf “My IP address is %s\n” “$_IP”*
    fi

I removed the -e from #!bin/sh than rebooted, restarted amidiminder and still got no connection

insert this two lines at the bottom of rc.local

amidiminder -f /etc/amidiminder.rules -C
sudo systemctl restart amidiminder

I´ve put it not at the end, cause it means behind the exit

#!/bin/sh
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will “exit 0” on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

amidiminder -f /etc/amidiminder.rules -C
sudo systemctl restart amidiminder

# Print the IP address
_IP=$(hostname -I) || true
if [ “$_IP” ]; then

  • printf “My IP address is %s\n” “$_IP”*
    fi

exit 0

does not work, not with reboot nor restart amidiminder :roll_eyes:

It´s a matter of syntax for PD, correct one is:

Deluge:0 → Pure Data:0
Pure Data:1 → Deluge:0

Note that each single port has an ascending number
