And now…
I have the second one RPi 2 as KODI.
I pushed the micrSD with Zyntihan, and the result is … the same.
I need to found some virgins and crucifixes …
I make one demo for you. Listen to second half.
By mobile phone, sorry for overcrowding.

It’s not normal.
I think the best way of helping you is start from scratch and document all the process with detail:
- Re-burn the SD with a fresh Gorgona Omega v2 image
- Boot and configure the display (HDMI) and wiring layout from the webconf
- Test again without changing anything.
- Update the software from command line. You should update twice.
- Reboot and test again without changing anything.
If you have XRUNS (crappy sound), please run “top” and capture an screenshot.
Document all the process and send a report specifying all your hardware, including the display, etc.
Also, include the full name of the image file you are using, etc.
Please, don’t assume anything. Something is wrong with your setup or you are making something wrong. The best way we can help you is you give ALL the details 
Thanks,

Okay, I’ll do it all the third time. 
I have no wiring. I am useing mouse for testing (controlers are on the road).
I have this one: zynthian_gorgona_omega_rbpi3_kitv2-2018-04-03
OK! Then you have to select “Dummies” layout 
This is perfectly OK.
Regards,
and mod-ui is not running as well when you start pianoteq?
Yes, i know.
Only for sure:
- rpi-update
- apt-get update
- update-zynthian
OK?
i don’t think so. not the first two
No my friend! Simply:
/zynthian/zynthian-sys/scripts/update_zynthian.sh
And do it twice!! It will take some time, so be patient …
Kind Regards,
No boys, at first: date +%Y%m%d -s “20191109” because certificate error 
It’s the date of your zynthian. For some reason it didn’t get updated …
Try rebooting …
Regards,
Not, it sets zynthian by myself.
One question: when i started mod-ui in the past, does it start automatically after restarting of zynthian?
Reflash, update, reboot, update, reboot … and nothing has changed. 
Not, mod-ui is not running.
It must be a bad SD card. Must! Or a few virgins will be crucified. I go searching for another one.
I am gone. 2 different R Pi (2 and 3+) , 2 different sound card, and now 2 different SD cards, 2 different keyboards, 2 power pupplies and 4 instalations.
The situation is worse with this new sd card (even one key plays crappy in Pianoteq).
My level of frustration is at its peak.

It’s very easy to react to technical issues emotionally.
The true wonder is the existence of the idea, the mechanism to transfer it, and the availability of parts.
The best part is electrons don’t care they just do what they do, and if we manage to divert enough of them at the right time we can make them sound like a piano 
It’s all a big trick really !
Is it normal? No, Zynthians (even modified, self built ones) play piano sounds well enough to fool most ears without digital electronic artifacts.
Did anybody have the same problems? Probably not exactly the same, but we have probably seen many of the things that can go wrong when you combine a Pi, an audio card, a display, an encoder card, mice, midi ports, ethernet and power supplies.
Is there a solution? Yes. But you will need to implement it. You need to not just refine your tech ( generally this means soldering the encoder card ) and as equally importantly ensure your workflows.
Are your techniques for downloading Images sound?
Can you make images that work properly?
Does building a raspbian image with alsa and jack allow you to load ZynAddSubFX and play sounds with an equal level of performance to how it all behaves with the zynthian providing the operating system?
Only Three !!?!?!? No seriously, you get better at this sort of thing but it’s about procedure, burning images is probably the most error ridden part of the process and it’s the one you want to be most relaxed about doing. Personally I use the gnome-disk utility in the xfce desktop, and I always clear the disk completely but I suspect everybody has there own spells and incantations they mutter.
We should probably check with hashs but I know I don’t and I’m not even sure if such a concept is relevant in unpacked image world.
The rebuilding of all hardware components is frankly a pain. I spend much of my zynthian time doing it and you often have to walk throu’ set up again: The zynthian set up mechanism, is very fine. The webconf addition really did move us forward incredibly, from the file munging early days of setup.
But it’s still down to several zynthian apps talking to hardware, and hardware can always confuse software. The difference is we can change the software remotely by mutual ideas but the hardware is on your space ship! We are just on the radio!
Sorry this is’nt technical help but It’s a assurance that your frustrations are understood and shared, and we will share your delight when it works!
I’ll get my coat.
