I have the following patch that is working on my Mac.
I upload it to my Pi 2 and when I try to open it pd crashing and close itself.
Can someone see what the issue might be?

Main_ver4.pd

@FFW
Thanks for your help!
my pd patch is already autostart. I don't remember how I did it, I think via the 'lxsession' as I found in that thread .
How can I disabled my way of autostart my pd patch?

just to make sure I understand your script -
It will autostart my patch when first powering the pi as well restart it when it crashed?

Another question I regarding opening the pd patch without gui. Do you think is needed? it can help with something? if so - I can I load the pd patch without gui?

Thanks!

With systemd you don't need to open a user session. It saves resource and help to keep puredata reactive.

NB : I think you can't launch a GUI with systemd as the X server may not be launched when the service starts.
so you have to append the -nogui option to the ExecStart line.

$ pd -help
[…]
-nogui           -- suppress starting the GUI
[…]

*edit: I have found it inside the lxesession folder .
*How can I find how and where my pd patch is starting and cancel it? :/ I don't want to write your script before I'm cancelling my autostart of the patch I have already made in the past.

@FFW said:

then run
sudo systemctl enable my_puredata.service to enable autorun at rpi start
and
sudo systemctl start my_puredata.service to launch it just now

when I run the last line of code it should autostart my pure data patch if I did everything the right way? because it did not start my patch..

I have change the path in yellow to be the correct path where my pd patch is located.

What about the lines in purple and blue? Do I need to change them as well? because I did not.
If so - how can I know to what I should change them?

Thanks

@KMETE
/usr/bin/puredata is the path to the executable, you can check it with

whereis puredata

WorkingDirectory is not used by PD but it's good to point to a user writable place.

-nogui is mandatory (I just test) as the systemctl process has no right on X server to start a GUI

You can see information about failure with

sudo systemctl stop my_puredata.service
sudo systemctl status my_puredata.service

Where do I add the -nogui command? inside the "MY PureData service" script?

@KMETE yes, in the ExecStart line

[Unit]
Description=My PureData service

[Service]
Type=simple
LimitNOFILE=1000000
ExecStart=/usr/bin/puredata -nogui  -open /home/pi/mypatch.pd
WorkingDirectory=/home/pi
User=pi
Group=pi
Restart=always
# Restart service after 10 seconds if service crashes
RestartSec=10

[Install]
WantedBy=multi-user.target

I've got 3 paths to that. How can I know which one is the correct one?

So here is the script I try to run with "sudo systemctl enable my_puredata.service"

I got the following error:

Do you see where my mistake is?

Thanks

@KMETE
/usr/bin/puredata is the good path

You write the Description= line in the [Unit] one, insert a line break.

@FFW
Thanks. No error now but the patch is not playing when I reboot my Pi.
Here is the command line after running: sudo systemctl status my_puredata.service

When I opened the same patch "mypatch.pd" with gut (I double clicked the pd patch) the sound is indeed coming out and everything is working.
Can you see where is my mistake?

Thanks

I run again to check the status and I'm getting lots of errors now:

@KMETE
No idea, may another program use the sound card ?
Try to stop the service before ask for status, it could give more info.

@FFW
I will try asap. (without the Pi now)

I have another two question. One is related to Raspberry Pi.

1. Is it possible to load mp3 files instead of wav file or the tableread~ object can read only wav?

2. when I'm transferring audio files to the Pi (to the Documents folder for example) - Do they stored on the sd card? or on the internal Pi memory?

Thanks

Hi,

1. Try to search "mp3" on the forum: https://forum.pdpatchrepo.info/search/mp3?in=titlesposts&sortBy=timestamp&sortDirection=desc&showAs=posts

2. RPi has RAM and SD card. Until you create a tmpfs for your documents they're stored in the card.

my pd patch is larger then my screen size (need to scroll down and to the right in order to see the full patch)
However, when the patch is open in the pi I have no option to scroll in order to see the full patch.
How can I fix this?

@KMETE Interesting...

PS.... looking at the problem a little harder..... it seems that the scroll bars are probably present, but off screen..... so reduce the size of the window so that you can access them.
Right-click the patch window (above the Pd menu bar) and "resize" and drag the window to reduce its size........ and they should then be on-screen.
If you cannot get to that menu then edit the first line of text in the patch file...... (something like #N canvas 0 93 1024 675 10; )....... reducing the window size (the 3rd and 4th values.. x-size and y-size).... so that the entire window is on-screen.

Where is the resize button? I can't find it - could you perhaps screen shot it?

@KMETE It should be where the patch name is above the grey Pd menu bar.
On my Pi it is a blue bar...... but maybe for you it is black (your window colour scheme is different). I can see on your screenshot what looks like the bottom of a white rectangle in the black bit...... so maybe if you right-click there..... or in the surrounding black space..... you will get the drop down menu with the resize tab.

Otherwise you will have to edit the patch file. Make a backup just in case. Then open it in a simple text editor.
At the top you will have something like
#N canvas 10 93 1024 675 10;
Change it to.....
#N canvas 0 100 400 300 10;
and save the file.

When you open the patch again in Pd it will be much smaller on the screen and will have scroll bars.
You should then also be able to resize it by dragging the corners...... and save it so that it reopens at the size that you want.
