As far as I know soundcloud is non profit.
I've seen original works and remixes though.
I've had instrumentals I didn't make up with my voice for years now.
I don't have it downloadable don't know if that matters.
Any copyright stuff is low on the radar especially if it isn't popular.
You're not making money so I said fluckit.

There's some really interesting setups out there.
I've been learning about midi stuff..
There's one that can translate your humming into a midi file, pretty wild.
