ZynthianOS: the upcoming Zynthian SD image


You can download the latest ZynthianOS nightly-builds from here:





We removed the ttl generation of DISTHRO which needs to be fixed, but still.


Greaaaat!! We are sooo close now … currently I’m on holidays, but i will work on the TTL generation as soon as i come back to home.

Thanks for your great work!!


Hi guys!

I updated my Zynthian with the last image available for download.

I noticed a small problem in the AmpVTS - CAPS plugin. When I add it to the pedalboard, the plugin is muted.

Any tips?

Just got a Pi Zero up and running Raspbian Lite.

This tells you how to boot without anything other than a PSU !!

Basically you build an image with a wpa_supplicant.conf file in /boot
and also an empty ssh file to enable ssh

Well it saves having to buy Micro HDMI cables!

and you don’t even need a mains PSU … .


The new nightly (which is not stable at all) comes with a file zynthianos-wpa-supplicant.txt in the boot folder, so you don’t have to create it.


I suspect I’m going to have to get a screen on it to see what it’s actually up to.

More money for amazon cables . …


So how should we report issues with this? github zynthian-sys?

1 - Its causing Pianoteq with the new Steingraeber to crackle (I assume thats cpu issues) significantly ie sometimes every minute or so as I’m playing.

2 - the encoders do not work at all. Boots into zynthian fine with no error but encoders don’t work

3 - small text, reorganization is hard to evaluate without working encoders because it definitely makes the touchscreen much harder to use.

4 - X11 forwarding (required for pianoteq licensing/configuration) is broken because of the pi user acting as the ssh login point. Adding a password to root is the most direct fix. If my X11 forwarding foo was stronger maybe there is a better workaround?


zynthian-sys is a good location to report to. Sorry for the delay. I didn’t see this here.
