You must purchase a pro licence for every soundpool which contain a loop that you use - these are available from Catooh - see here for the different licence types available.
Note that you purchase a licence to use the soundpools commercially - however you do not own and cannot claim copyright on any material you produce using these sound pools.
If you want to own copyright of your works then you cannot use the soundpools even if you have the licence to use them commercially however you can use the program to create them providing you compose, and create / play the entire work using:
1. Builtin Synthesizers
If a built in synthesizer is used with the music or beat patterns that are built into them then you must refrain from using the sample melodies for the melodic software synths
A synthesizer must be controlled/played from a midi keyboard or entered using the Midi Editor, using own composition with the built in instrument sounds eg Space Pad, Church Organ etc, no special license needed (or available).
You must refrain from using the built in synthesizer melodies eg double click Revolta for example will put a melody on the timeline.
Drum synthesizers are the exception to copyright / licencing - they are too generic.
2. Own recordings
You can use the program to record yourself playing an instrument, eg guitar, without the need for a Pro licence
Copyright infringement claims
Please be aware that you may get copyright infringement claims form others who have used the soundpools to create music legally or otherwise. This is inevitable, however incorrect - Copyright of the soundpools belongs to Magix and is never transferred with any from of licence.
If I create a song using the sound pools with unlimited commercial license, can I never copyright my song even if the overall music notes and melodies are my own? So I cant get music royalties from radio stations even though I have unlimited commercial license to use the sound pools? I'm confused how this is unlimited commercial use if I use any part of a sound pool in my song I can no longer register it with a music organization as my own song.
On the other hand . IF you use Only Synthesizer instruments , your song is automatically yours , provided you made your own original melody , and you played all your original notes with synthesizers .
Magix has a email , before buying a sound pool license .

I think ( not sure ) , all Sound Pools come with Standard license . Unlimited License could be as much as 1,000 a pop . If one song uses 5 sound pools is that gonna cost 5,000 ? I don't know . email Magix to find the answer .
