Thanks for the feedback. I started this in the Off-Topic forum since it isn't explicitly Magix in topic, though in fact I would be using Magix to create a recording of my own of this or that hit song I have the sheet music for, so it does have a connection implicitly. I just now looked at the legal tab at the bottom of the Sound Cloud page. "Any unauthorized use of copyright protected material within Your Content (including by way of reproduction, distribution, modification, adaptation, public display, public performance, preparation of derivative works, making available or otherwise communicating to the public via the Platform), independent of whether it is or becomes unauthorized at a later point, may constitute an infringement of third party rights and is strictly prohibited."

I take that to mean I can work up my own recording of George Harrison's 'Here Comes the Sun' for playing in my own house, but I would not be allowed to upload it to Sound Cloud for anybody else to hear.
