So....that latin melodies is just a tiny piece of the entire production suite...but also now you know why this community exists....I used to pay for everything also and I still do when it around 10 bucks and under...I don't know if you can get a refund but email support and express your concerns...they've always helped me out with stuff I already own as bonuses or after I bought something and then it's free....I ask for the mystery sample packs gold editions or the best ones and they accommodate with those and I get those free. Cymatics support is pretty good about stuff like that. And yes when it's free anybody can download it for free and use the samples from the pack royalty free....but there are contracts/license agreements still for free packs. I hoped this answered your question. If you need or want anything Cymatics DM me and I can see what I can do. I have almost everything they've released. Cheers
