I have some "ancient" Magix CDs (MMM 5, MMM v2000, Live Act Pool) that have soundpools in them. The license file specifies:
USE OF ALL SOUND FILES EXCEPT THE FILES ON THE ARTISTPOOL CD ROMs
All created works can be used royalty-free for commercial or personal purposes under the condition that the works visibly contain the reference "MAGIX CREATION". You will find the logo "MAGIX CREATION" on our website http://www.magix.com. If you do not have internet access, call MAGIX and you'll receive the logo by mail.
The MAGIX website does not seem to provide a "MAGIX CREATION" logo anymore. Any idea if this logo requirement "officially" changed at some point? (for the older licenses I mean, I know that newer licenses don't have this)
