DJ.Studio's Stems feature uses a separate extension, which needs to be installed separately before it can be used.
These extensions can be installed through Settings > Extensions
On some systems DJ.Studio isn't able to install the extensions. Most of the time, this is due to blocked network access of DJ.Studio.
Acces needed
The DJ.Studio app need to be able to reach the following URLs to install the extensions:
https://extensions.dj.studio/* for extension information
(if you open this in the browser it will give a 404, this is expected)https://cf.dj.studio/* for Extension updates and sending over support logs
(if you open this in the browser it will give a 401, this is expected)https://*.r2.cloudflarestorage.com (notice the wildcard!) to download the extensions.
If you are working on a secured network, for example, at work, or have a heavily secured machine, restrictions might block DJ.Studio for using these URLs.
You need to make sure the DJ.Studio app is unblocked for these URLs.
Please note: You might be able to access those URLs from your browser, but that is not enough; the DJ Studio app needs to be unblocked.

If you have the same issue again, share your logfile with us after you tried to install. (Don't restart DJ.Studio as this will clear the log!)

Issue 4 : Stems doesn't start or work
The extensions' installation is all good, but when I try to use Stems, they don't start or work.
This could be caused by multiple things, a shortlist:
Antivirus programs block the execution of the extension
Solution for Windows: Follow the steps in this articleThe extension won't run due to missing requirements on your system (mostly MacOS)
Solution: Reach out to support with your logfile, we can determine the cause and help you get you up & running.
