Hi,

Your question is very short but very difficult to understand. It would be better if you would have explained what you want to do in some details.

Open Magix Music Maker, you will see empty tracks, marked 1,2 3 on left side right. you got various options to fill these tracks. Choose various styles from soundpool, drag and drop instruments on arranger edit them as you like then File/Export in format you like, before that save please or you will have one track. you can keep adding other track in emtpy tracks, then edit your music and save/export.

You can also record in empty track from Mic/Keyboard/synthesizer. Saving project first will help you to edit later.

For reference you can check
