Not that I know of. I just know he releases Demos and teasers. And right now. It's not a bad offer with the amount of demos he has put out that you can download once you become a Patreon Member. Also, theirs tiers that get you instrumental versions, and one gets you the stems.
You can also stop contributing if you want to and then later on, continue contributing again and get access to the stuff you didn't get when you stopped the membership. I did that, as I forgot to update my card info for the site. It was fun seeing what I missed...
