Problem with Pianoteq

Jeremias · October 4, 2024, 1:51am

After purchasing the Bosendorfer on the Pianoteq website, I tried to activate it.

However, today the Pianoteq website was experiencing a very slow performance, and for some reason my license appeared as invalid.

I decided to restart Zynthian and now ZynUI won’t start.

I investigated using the command line and the output of “journalctl -xe” looks like this:

Oct 03 22:50:29 zynthian-jere startx[4158]:   File "./zynthian_main.py", line 35, in <module>
Oct 03 22:50:29 zynthian-jere startx[4158]:     from zyngui.zynthian_gui import zynthian_gui

Oct 03 22:50:29 zynthian-jere startx[4158]: KeyError: 'val'

I edited the “zynthian_gui_engine.py” file and commented out line 74 onwards (in the part related to pianoteq) and the interface started up again normally.

As soon as the Pianoteq website started responding a little better (although still quite slow), I ran the command:

/home/pi/zynthian-sw/pianoteq6/pianoteq --activate MY-SERIAL-NUMBER

And after 4 attempts, it activated the license correctly on the command line.

I uncommented the lines in the “zynthian_gui_engine.py” file but the error came back and ZynUI stopped starting.

Hi All,
I did the following 4 times (not all exactly identical…)… just to be sure…

I started-up an new image (think the one from 02-10-2024) and defined my audio and such… started up… all OK -)
I uploaded the 8.3.2 pianoteq image rebooted and back in the webconf screen I filled in my serial number… saved and… “500: Internal Server Error”
The webconf pages are accessible but not the pianoteq page…
Reboot…
Software error… no access to webconf anymore…

Help!

With pianoteq 8.3.1 the same issue… after activaing license… Webconf not accessible anymore… Zynthian unusable.

Cheers,
Maarten

maartmaart · October 4, 2024, 7:22pm

I repeated all on a different PI5…

Installed pianoteq 8.3.2, rebooted and filled in serial key in webconf… result:

Activation Failed
An error occurred during the activation:

Warning* : Undefined array key “f” in /home/pianoteq/www/corporate_v34/php/vendor/modartt/essentials/src/Activation.php on line *535

Hi @Jofemodo,

Thanks, quick as ever

I saw it, I shouldn’t have sent this message… must have happened in the sequence of events…
I tried everything. I started with installing pianoteq on the device that was registered by Modartt, thinking that that should work.
And from then on I lost track of all I did, but finally used a different PI5…

I will try monday again and perhaps contact Modartt.

Enjoy your weekend,

Maarten

maartmaart · October 6, 2024, 5:57am

I finally succeeded on the initial PI5… no clue what went wrong before… (except the re-activation on the second PI5 forgetting that already 3 devices where registered)

Cheers,
Maarten

Hello

My problem persists, I haven’t seen any suggested solutions to the problem I’m facing.

I don’t understand why my topic was marked as resolved.

@jofemodo ?

jofemodo · October 7, 2024, 12:59pm

I was confused because @maartmaart solved his issue, but now i see he wasn’t who opened the thread.

jofemodo · October 7, 2024, 1:01pm

Regarding your issue, @Jeremias, we can’t reproduce. I’ve installed Pianoteq licensed without issues. I think @riban also tried successfully. We would need extra info to reproduce/solve your issue.

Of course, you modified the source code, run the pianoteq by hand to install your license and then removed the modifications. This is not the expected workflow and we are not going to work in this “workflow-fork” for a single user.

You should try reproducing in a clean install.

Thanks!

Jeremias · October 7, 2024, 1:07pm

Thank you for the quick response @jofemodo

First of all, I must admit that I don’t know what information I should collect to continue the diagnosis.

But as I described in the beginning of the topic, when I disable Pianoteq in the file “zynthian_gui_engine.py”, Zynthian runs correctly. But if I leave the file uncommented in the Pianoteq section, Zynthian doesn’t start, and even the WEB interface crashes.

I honestly don’t know what else to try. I don’t know if it would be possible to reinstall Pianoteq via the CLI…

jofemodo · October 7, 2024, 1:26pm

Try installing from scratch and switch to vangelis branch before installing Pianoteq.
And please, capture the logs for all process in the clean install.

Regards,

Jeremias · October 27, 2024, 11:59am

Hello @jofemodo

Is there any way I can just reinstall Pianoteq and fix my problem without reinstalling Zynthian from scratch?
I have a significant amount of samples, snapshots and custom settings on my Zynthian Box and I don’t know what strategy to use to avoid losing all of them.

jofemodo · October 27, 2024, 4:34pm

Try running this command:

$ZYNTHIAN_RECIPE_DIR/install_pianoteq_demo.sh

Well you could always leave a cross-section in use here…

Hello

First of all, sorry for the delay in responding, I was traveling for work.

The procedure for reinstalling the Pianoteq trial that @jofemodo suggested worked partially.
He managed to restore my access to the Webconf screens, my snapshots worked and everything else. However, in version 7.5 (which is the version of this installer) my license does not work.
So I tried to launch an older version of Pianoteq, in this case 8.3.0, which was the last one that worked. Then I came across the error again.
And this made me pay attention to a detail, so I believe I diagnosed the problem.

I believe the problem is somewhere related to the Pianoteq licensing. Because for some reason the serial number got “stuck” in WEBCONF, I can’t delete it or overwrite it. Whenever I try to upload a version of Pianoteq higher than 8.0 (the one my license is valid for), WEBCONF displays error 500, after which the Zythian service crashes when restarted with the same log lines that I showed at the beginning of this topic.
An interesting thing, if I try to apply the license in Pianoteq via the command line, everything works OK…

I wonder, is there a way to delete my licensing data from WEBCONF, or via the command line? I thought if I could reinsert the serial number via WEBCONF, maybe I could fix the problem.

Thank you in advance.

After my last post on this forum I did some more research and with the help of the find command I found the directory “/root/.config/Modartt/” which contained several Pianoteq prefs files, including licensing inside.

I backed up the directory and ran the “rm” command to delete all of its contents.

This solved my problem!

It deleted the license key and I was able to update to version 8.4.0, then I just had to reinsert the license key and now everything is working correctly.

Now I just need to finish my tests calmly to update Pianoteq to the latest version.

You can mark the topic as resolved!

Thanks to everyone for their help.
