WARNING!!

The testing version contains new features and a lot of fixes but it could also contain new bugs and unknown issues. It may change without notification. Don't use it for production without deep testing! See below for information on how to choose a version.

3 Unzipping

The file you download is a zip or xz file that must be expanded to get a .img file that can be 'burnt' to the micro-SD card used by the zynthian device (Raspberry Pi). This process differs depending on the operating system you use: windows, mac or linux.

4 Preparing the SD-card

Latest SD-card image weight around 8 GB compressed and around 14 GB unzipped. It includes all the software you need for your zynthian, properly configured for working out-the-box with the latest official kits. Completely ready to use. Plug and play!

After downloading and unzipping the SD-image, you have to write it to a suitable SD-card. You need a good-quality SD-card with a minimum size of 16GB. You can use a bigger one if you like.

You can use Etcher, a free software that works on Mac, Windows and Linux, to write the image into the SD-card. There is a really good manual for this at this link.

If you are a terminal guy, dd or pv will do the task. Don't forget to unmount the SD partition before burning and sync before extracting the card. With root privileges, run something like this:

umount /dev/sdc1
pv 2023-08-25-zynthianos-stable-2308.img > /dev/sdc
sync

or if you are a sudoer:

sudo umount /dev/sdc1
sudo pv 2023-08-25-zynthianos-stable-2308.img > /dev/sdc
sudo sync

Note:

RBPi2 is not supported by recent zynthian SD-images. If you want to use a RBPi2, you may need to build your own SD-image.

5 First Boot

First boot could take some time. Be patient and wait until you see the splash screen with the logo. If you have a recent kit (V3, V4 & V5) and the display remains black after 1 minute, please, re-check the instructions above and re-burn the SD-card again. If this still doesn't work, try with a different SD-card before reporting in the forum. For solving SD-card issues, it could be useful to check the RPi4 status LEDs.

Once you see the splash screen, it could take some minutes until the system is ready. You deserve a beer, or at least some tea or coffee. When the first-boot process finishes, the zynthian will reboot and you will be in the main menu, ready to play.

6 Configuration instructions

Recent SD-images auto-detect latest official kits V3, V4 & V5. If you are using an older kit or a custom hardware, your first step after booting should be accessing the webconf and configuring your hardware.

• For accessing the webconf tool, see here
• Once logged-in, go to Hardware -> Kit and select your kit version or "Custom". Click on save button.
• Then, if you have a custom hardware configuration, configure each device: Audio, Display, Wiring. Use "Dummies" if you don't use any encoder/switch. Don't forget to save your configuration after each step.
• When everything is configured, you can reboot zynthian using the System -> Reboot menu item

7 Choosing a software / firmware version

The image you download will set zynthian to the corresponding version, e.g. if you download the stable image then your zynthian will be configured to use that stable release. You may wish to change from the stable release, for example you may want to test a feature or bug that you have reported or maybe there is a need to protect your system from being updated. Webconf provides a mechanism to change the version under its SOFTWARE => Repositories options. The table below details how each version behaves and gives some hint as to which you may prefer.

zynthian versions

Release type	Example version	Risk level	Description
Stable	zynthian-2409	Safe	The current major release. This is what most users should select and is what each stable release image will be configured for. Only fully tested, stable updates (point releases) will be advertised. If you want to experience the latest fixes and enhancements but want a stable platform, this is recommended. (See point release below for those who want even lower risk.)
Staging	oram	Adventurous	Staging branch is where fixes and enhancements to the current stable release are tested before being released in the next point release. Users who want to use the latest version with fairly low risk and early access to updates may choose this version. If you were using staging before its major release, you will continue with the same update experience but lower risk of breaking.
Point release	zynthian-2409.0	Paranoid	A point release is a specific stable update. Chosing a point release will lock the zynthian to that stable version and will not receive any further updates. For users who have found a version that works and do not want any further changes.
Development	bug/1196_zynaptic	Desperate	A branch that is developing or testing a specific fix or change. This branch may not include other fixes and will ultimately become a dead-end. For developers and users wanting to test a specific development effort.
Next Staging	vangelis	Wreckless	The bleeding edge development for the next major release. This branch will change without warning and may be broken at any time. For developers and the most adventurous users.

8 Build your own SD-image

If you like, you can build your own SD image following these instructions:
