In the subject, you mention Video Deluxe, but in question refers to Video easy. Which Magix program and version are you referring to?
If Movie Edit Pro (MEP), which version - regular, Plus or Premium, and which year? Did you install all of the add-ons under Help, Free download?
What do you mean by Music? Are you referring to music that comes with the MEP, such as Slideshow Music or Soundtrack Maker Styles? In MEP they are available under Edit, Wizards - Slideshow Maker or Soundtrack Maker. You can find the audio and music files in the ProgramData folder on your C drive under:
C:\ProgramData\MAGIX\Movie Edit Pro 2014 Plus
If you mean, how to add your own music, then you can simply drag and drop your file onto one of the tracks in the timeline.
I hope that you are able to understand this, as I know that English is not your language.
To find the music for the Slideshow maker, go to the Import tab and open My media. You will see Slideshow Music. Click on it. There you will have music for the Slideshow maker in various folders. Open one of them to see. You can drag and drop a music file onto the timeline. See below.
These files are located at:
C:\ProgramData\MAGIX\Movie Edit Pro 2014 Plus\Slideshow music
If you cannot see C:\ProgramData in Windows Explorer, you will need change the options in Windows Explorer to view all folders or hidden folders.
Just above Slideshow Music is My music. If you have music albums on your computer, they will show up there.
For Soundtrack maker music, select Edit, Wizards, Soundtrack Maker and the following dialog box will appear:
Choose the style from area 1 and the mood at the right under area 2.
These files are all at:
C:\ProgramData\MAGIX\Movie Edit Pro 2014 Plus\Soundtrack Maker Styles
