If I am trying to publish music made from various loops - loops purchased over a period of two decades either via previous version of Magix or Sony music making software (as in many different versions) - how do I get documentation to show that it is ok for me to use the loops for publication?
@Justin-Loop In case you have loops on discs like CDs and DVDs there should be a license file on the disc that tells you that you can use the loops commercially. If there is no license file on the disc the license should be in the booklet.
If you bought something from ProducerPlanet you can login into your user account and look under "My products" what loops are licensed for commercial use. If you bought something from the old catooh site you should look up your receipts in your e-mail account.
That's what I would suggest to do.
Here is the link to the Sony Loops EULA:

It's one of the least restrictive. Basically it says "You are free to use the Content Offering in your own original compositions without restriction". I'd suggest printing it out and keeping on file.
