Hi @zynthianers!
I think it’s time to release the Buster RC-3 SD image. Let’s start with:
https://os.zynthian.org/2020-08-05-zynthianos-buster-lite-armhf-1.0.0.zip
Stop downloading and testing this image. It’s not workig OK…
and report to this thread …
Regards!
BTW, last nightly builds have default assignment for the 4 extra switches:
It’s only a starting point. I hope to make more self-contained the ZS3 (subsnapshots) functionality.
Regards,
Hi 
Is it to be considered the new default stable version, then?
No. We have to test it to be sure all the functionality is working OK on it. If some problem is detected, it will be fixed and a new build will be proposed.
Regards,
Installed it today, basics seem ok - will give it some proper testing in a bit.
Don’t forget to test the surge engine with the 2 only presets available. It should work …
Regards
Well, I tried it on my Zynthian Kit 4 (Pi4) and it doesn’t work for me… (exactly the same issue as I had with snapshots newer than rc2): the screen doesn’t come on at all. Clean flash of the image, straight boot. The zynthian.sh can’t find the screen and it never powers on.
Webconfig works and I can login, so I could troubleshoot if there is any interest, otherwise I’ll have to flash back to rc2 again (and probably get a second sd card for a stable version…).
From the webconfig UI log I see the same error:
./zynthian.sh: line 55: /sys/class/backlight/*/bl_power: No such file or directory (note that this error didn’t occur on rc2 and the screen worked fine)
root@zynthian:~# cd /sys/class/backlight
-bash: cd: /sys/class/backlight: No such file or directory
it seems that it doesn’t load the driver for the screen or something…
any pointers apppreciated to help troubleshoot this.
EDIT: I’ve reflashed to rc-2, which powers the screen on without issue, and will allow me to make some music. (I can’t help in testing or troubleshooting this issue further, but I do hope it gets solved or I’m stuck on rc-2, or it’s another issue…). I’m getting a second SD card to keep a stable ‘known working’ version around.
Surge is a synth layer? It’s not showing for me.
Btw, I did a totally clean install on a Raspberry Pi 4 if that helps for @twelve. I had some strange issues upgrading with the last build too - for me layers wouldn’t load but this is working much better.
New V4 just build yesterday…
Screen was okay (but not detect my USB MIDI Keyboard) with the buster RC2…
RC3 in test now, and I get no more screen !
Here is the log from WEBUI, for the UI LOG:

Still testing !
+1
same for me
Ah, happy to see that somebody is confirming the same issues as I had, that means that the odds are raised that this image most likely won’t work out of the box with a v4 kit for now. (and the odds are lowered ever so slightly it’s a hardware issue on my side)
I hope it can be reproduced 
Now here’s one for the clever among you. How in an entirely Pi infrastructure like what zynthian Towers have recently become do I burn images…?
This issue, jitsi chat’s with castle riff raff, and Nord Modular GUI’s are the only thing keeping my old laptop alive. . .?
Normal castle rewards apply for solution of such problems.
You get fed next week.
What do you get from this command:
