I linked what they offer from their website. you can also record your own, or use other companies sound pools or sound files as long as they are in a standardized format such as .wav, .mp3, .ogg, and so on.
First sorry to John auvil, I hope I am not interfering your answer.
I did use Magix Music maker 16 then upgraded to Magix Music Maker 16 Premium because of more sound and other features. This is my advice, instead you buy Costly Soundpool DVD, why not try what it will cost if you upgrade to Magix Music Maker 16 Premium. As I remember in my case it was cheaper.
I suggest, compare features of MMM 16 and MMM 16 Premium then look at upgrade price, I am sure you will think of upgrading. In some countries Magix Music Maker 17 Premium is out, may be until next year it will also be available.
