I really appreciate your efforts and thank you very much.
No, I couldn't find it.Easyeffects already installed in ver1.10. (That's flatpak edition, latest Tangerine Fix can work only flatpak edition at MX-23)
I just ran the 1.10 ISO again, but I couldn't find EasyEffect.
That was the reason why I installed EasyEffect version 7.0.1-1 from the Debian backports.
I also looked through MxPi again.
It is not offered in the flatpaks.
I wasn't offered anything else either.
I had to run apt update in the terminal before MxPi flatpaks offered anything at all.
I have now wanted to catch up with the installation of EasyEffects via Mx-Pi-Flatpaks.
But the installation failed.
Once because of insufficient memory.
Another time the installation had much more space and also needed a lot of it 2GB !!!!
The installation seemed to have gone through correctly.
But in fact Easyeffect was not installed.
I have to say, I am not a fan of Flatpak.
It always takes up a lot of space and behaves like a virus crawling under my system
Do I understand it correctly?
Version EasyEffect-Tangerin-fix does not work in extrox version 9.1 or is not offered there via Flatpaks ?
Or could I also use this improvement in my already installed extrox 1.9 via Flatpak ?
( If I like to tray Flatpak again. )
