Only uninstalled the Viper4android ' app '. Viper Driver is still running on the phone... The New found viper's fx app is quite easier to use and to config (for me)... Because it's in German and you can choose setting modes...
It works fine so far...

By default if you flash concept ROM you can install viper4android there and it will be included automatically on the walkman music player. Just make sure SELinuxModeChanger is grantes superuser and is on permissive mode.

Why did you uninstall default viper4andriod for Concept ROM? Was it not working?

Only uninstalled the Viper4android ' app '. The default Viper Driver is still running on the phone... The New found viper's audio fx app is quite easier to use and to config (for me) because it's in German and you can choose setting modes (simple,..., expert). The missed option to install or check driver in viper's audio fx is a deficit so i ve choosed to let the driver installed. Afterwards I can't update the driver now :eek: omg. Should restore Viper4android, or looking only for driver updates to install /flash?? Is there a way to get an update patch?
It works fine so far...
I love it simple and clean but the quality must be present, within the viper's fx app i got all in one -1??
For simplicity and clearing i deleted the concept default Viper4android app.

Sorry, forgot to choose the second Screenshot...

I don't know how you can make the german version work for the music app settings but if you want to install the viper4android from concept rom you can just flash the rom again just don't wipe your internal storage and data so you don't lose your files and apps.

Flashed twice latest version (4.0), made a full wipe the two times. FC constantly, "Android version keeps stopping". I'm not able to go home launcher, this message pop ups every time I press home button.

Do a clean install?
Use 3.0.2 TWRP? The only one works well for this rom

Ha! you should be right about TWRP, I'm using a previous version.

Will update it and reinstall ROM. Will report soon.

Edit: Actually, I'm using TWRP 3.1.1, a newer version. Could this really be the cause of the problem?
