I've bought some songs and Soundpools, but cannot see how to add these to my system. It's certainly not intuitive. Can you provide some guidance please?
This is a place where user like you and me share knowledge and help each other it is not Magix support ok.
In your case, you did not mention your Music Maker version or windows operating system xp, vista or 7 anyway.
First of all you open Magix music maker, turn off easy mode refer image below
I assume you have saved your purchasedd song/soundpool on hard drive/cd/dvd or flash drive. Click on File Manager, you got options browse CD/DVD rom or folders,
Refer image below.
1. Click on Filemanager
2 or 3 it is upto you which one you chose for where your audio is saved.
2 is for drive 3 for CD Rom, browse and after locating click on it, that will be added in Media pool right side from their drag and drop on arranger. You can do whatever you wish with your audio.
Note: You can also browse audio from My documents or saved in Project folder.etc
