You can try LibraZiK-4 without installing anything on your computer. All you need is a USB key of at least 4 GB.

The following procedure will show you how to create a live USB key for the “LibraZiK-4 audio studio”.There are just a few steps:

• first, you'll need to get an ISO image of the live version of LibraZiK-4 ;
• secondly, you'll need to write it to a USB key;
• then, you can boot it up and try it out.

The ISO images contain a functional LibraZiK-4 system as well as a wide selection of free and open source software dedicated to music production.

Go to : https://download.tuxfamily.org/librazik/iso/ and download the librazik4-20240101-en-amd64.iso file for a 64bits version in English. Once downloaded, you will be able to check the ISO integrity thanks to its MD5sum Checksum which must be 4d9d31f22c1b232db063714dc92351bf.

Once the ISO image has been downloaded, open a terminal and go to the directory where the downloaded ISO image is located: cd /path/to/folder.

Now use the command (replacing file.iso by the full name of the ISO file downloaded in the previous paragraph): md5sum file.iso, which should return a checksum. You just have to compare it with the checksum given above.

If your machine supports it, you can write the ISO image to a USB stick and boot from it. Before writing the ISO image to the USB stick, it is advisable to delete and back up the files on it, then format it in “FAT32”.

1. In a terminal, run the command: watch "sudo dmesg |tail".
2. Then plug your USB key into your computer, you will see the inscriptions in this terminal change. It is your linux® kernel which is telling you that it is discovering a new peripheral and what it does with it.
3. Find out where your USB key is located. For example : sdb: sdb1.
4. Then, in another terminal tab (do: Terminal menu → File → Open a tab ), the magic command to write the ISO on the USB key to make it a bootable USB key is: su -c "cp /path/to/your/file.iso /dev/sdX" with replacing the “X” in /dev/sdX by the letter corresponding to the location of your USB key (in the example above: /dev/sdb)
5. Once the copy has been made and when the terminal gives you the hand back, run the sync command to make sure that everything is properly written on the key and that there is nothing more being written to the key caches.
6. Unmount your key cleanly.
7. Close the terminal window.
8. Your USB key is ready.

It has been reported (in French) in 2017 that the use of LiveUSB was functional for a LibraZiK-1 Live. This may still be the case, but has not been reconfirmed since.

Same method as above, simply replace the command:
su -c "cp /path/to/file.iso /dev/sdX"
by :
sudo bash -c "cp /path/to/file.iso /dev/sdX"
or, if this one doesn't work:
sudo dd if=/path/to/file.iso of=/dev/sdX

It has been reported by a user (Didier - thank you!) that with the “Ubuntu 16.04 Mate Alpha” version, the use of the “Ubuntu usb key creator” ¹⁾ made it possible to create a key.

It has been reported by the same user (Didier - thank you again!) that: “after downloading, I created a Live Usb key with Unetbootin and then launched it on a computer type i7-2600”. So it seems to work as well. That said, there may be some problems: bug 775689 at Debian. See also this tutorial.

It was reported by a user (Louis - thank you!) that it was also possible to create a USB stick bootable under Ubuntu with mkusb (see also this explanation).

There are several possibilities. Five of them are proposed below.

Possibilities tested and approved with LibraZiK-3:

1. A solution is the use of Rufus (confirmed by N-i-c-o on IRC with Rufus 3.12 with a LibraZiK-3 - that probably still work))

Possibilities tested and approved (with the old LibraZiK-2 version):

1. One solution is to use Linux Live USB creator. ²⁾
2. The utility win32diskimager works for that. A tutorial is here. Please note that you will need to put *.* instead of *.img when searching for a file.

Possibilities not yet tested/approved :

1. Yet another solution is to use unetbootin for Windows. See also this tutorial.
2. A last one is: USB-Writer. See also this tutorial.

See here.

From there, you will be able to try LibraZiK-4 without installing anything on your hard disk for the moment. To do this, simply plug the USB key into one of the computer USB ports and then start the machine. Of course, your computer must be hardware capable of booting on a USB ³⁾.

After this step, you will arrive on another step :

Here you will choose “Live (amd64)” by selecting it with the keyboard arrows and then pressing Enter.

Vous patienterez alors un petit peu et vous arriverez sur le bureau du live de LibraZiK-4. Y sont préinstallés une grande sélection parmi les logiciels de MAO supportés par LibraZiK-4.

You will then wait a little while and you will arrive on the LibraZiK-4 live desktop. A large selection of LibraZiK-4 supported audio production software is pre-installed.

To access it, go to the top menu → Applications → Sound and video → ….

You can install software from the repositories. However, if you launch an installation from the same live session, the software that you manually installed in the live session will not be hard installed. You will have to install them again, once you have restarted on your hard disk installation.

In case you need it, the login/password of the “live” is: user/live.

Also note that in “live” mode, sudo is used to access super user functions.
