Vangelis 2606 BETA Image is released. You SHOULD download & install!

Letoine · August 8, 2026, 5:17pm

Just installed this new version. But, impossible to install pianotek. Nothing was downloaded to the Zynthian by the web interface.

niels · August 8, 2026, 9:19pm

New image went just fine on Zynthian 4.1 with Pi5.

But pianoteq exposes a strange behaviour: after the first note three hisses keep on being output with a few seconds interval, until I remove the chain.

The first note in the audio recording is at 22 seconds, the first hisses occur a few seconds after.

I do not think this is due to it being a Demo version, on my laptop it works fine.

niels · August 8, 2026, 9:42pm

Update:

The version shipped on the image was, I think, 8.3.1. In VNC I saw it said it ‘really is too old’.

So I downloaded my 8.4.3 PRO version, activated the license, and no more strange hissing sounds.

May the hissing be something they add when the software is ‘really too old’? That’d be something…

tunagenes · August 9, 2026, 4:25am

Is this happening with ‘official’ Zynthian kit, if so which, or DIY? Could we get the webconf dashboard please?

Do you have any USB devices plugged in? If so please try eliminating them for troubleshooting purposes.

I wonder if 3 Amps is enough - can you try a 5 Amp supply?

I don’t know why you’re experiencing the problem only on a soft boot. I’m thinking maybe a USB device being enumerated causes a power drop, and the timing of enumeration varies with cold or soft boot.

riban · August 9, 2026, 7:33am

I have added a ticket to the issue tracker (like we all should be doing ).

niels · August 9, 2026, 8:13am

Yeah, sorry, it was late in the evening…

wanthalf · August 9, 2026, 10:47am

Oh, right! … however, it does not seem to be the cause, unfortunately …

Yes, my zynthian is a DIY embedded in a USB MIDI controller (which is basically permanently connected). It is powered by a custom power source providing 5V/5A to the GPIO of the Pi5. And yes, I forgot to transfer the option “usb_max_current_enable=1” to the new system’s configuration.

However, this used to show a different kind of misbehaviour before and … the issue remains even when using that option and even if I disconnect the USB-powered controller completely (the embedded display is also powered by the USB, though, but this never caused any trouble before). It happens from the first boot of the new image: it failed to reboot even after the initial image resize.

I have a kind of flashback that a similar problem had already been dealt with by @jofemodo when he built the first testing images for Pi5 years ago and it concerned just some particular versions of the Pi5, but maybe it is just some confused recollection or a plainly fake déjà-vu…? Am I currently the only one with this issue?

tunagenes · August 10, 2026, 4:15am

I can’t say you’re the only one, but I’m not experiencing a boot failure as you posted on either my V4, V5, or my DIY Zynthian. I do have an odd hang on my DIY Z with an RPi Touch 2 display and Phoinkas USB Audio Interface and Akai APC Key25 Mk2, and the symptoms changed quite a bit between Oram and Vangelis and it’s not clear whether it’s a timing or power issue. But the workaround is quite easy, just plug in Key25 after Zynthian has finished booting. Claude and I are working on figuring out what is happening which will hopefully lead to a fix.

piattica · August 10, 2026, 8:38am

I have Shutdown issue with Vangelis beta: (Issue: Shutdown launched from Zynthian menu does not complete · Issue #1748 · zynthian/zynthian-issue-tracking · GitHub)

Press OPT ADMIN button on LCD screen
Press Power button on LCD screen
Press Shutdown button on LCD screen
Zynthian screen show Shutting down… screen but Zynthian does not shut down: if you for example go on Webconf
it responds correctly and if you launch Power off from Webconf, Zynthian swithc off.

C0d3man · August 10, 2026, 12:19pm

Me, too.

Thanks for reporting!

BertB · August 10, 2026, 1:24pm

I really love the Vangelis release and whenever I see the update arrow, I do the update. During the update yesterday however, I got this in the feedback:

jofemodo · August 10, 2026, 10:45pm

It looks like some packages were not installed in the update. Did you try to update again?

BTW, are you using the Beta SD image, right?
As i explained above, bookworm-based Vangelis is no longer supported.

Regards

wanthalf · August 10, 2026, 11:30pm

I can also confirm both issues reported here above.

BertB · August 11, 2026, 6:21am

I do use the beta image and tried to update several times.

wanthalf · August 11, 2026, 10:38am

@jofemodo If you cannot replicate, should we check for some missing packages or configuration files? Maybe we just updated too eagerly and something got uninstalled or overwritten at some point…?

BertB · August 11, 2026, 11:07am

That crossed my mind, but I do not know how to check it. For now, I am going to load the image again and see what happens

HansR · August 11, 2026, 12:29pm

Same problem here and shutdown doesn’t work either. (Vangelis Beta, update one minute ago).

Edit:
Like reported here:

BertB · August 11, 2026, 12:49pm

I think there might be a problem with restoring setups with firefox and windows 10.

I can make a backup via webconf but it is impossible to restore it. It does however work with Edge.

jofemodo · August 11, 2026, 2:31pm

It look like we still have issues with "failed updates". You can fix this by running the update from command line like this:
echo "20260802.1" > /zynthian/config/patchlevel.txt update_zynthian.sh

Sorry … not needed at all!
My fault. I missed to push some recent update recipes!
Please, try again.

Regards!
