Hi there @Nokka
Thanks for reaching the forums & your interest in this Reason tutorial, and yes, if you are already familiar with Reason 10, then this tutorial is probably not one where you will learn that much since it's not covering advanced stuff.
The lack of more tutorials & advanced ones on Reason is due to the fact that S.A doesn't have so much request about it, they did a few series on the past versions of Reason too and sadly that did not seem to reach a large audience. That said there's some other tutorials like "How to make" full tracks that were covered in Reason.
Now next to targeting a specific DAW and covering it's advanced techniques & tricks, there a lot more knowledge to grab here on S.A. As a moderator on the forums I can tell you that many users are happy to learn so much out of S.A tutorials.
Many people also follow tutorials that are not done in their own DAW and the feedback about learning even more because they have to adapt the techniques to their own production environment is quite positive here.
So not trying to sell anything, that's not my role here, but have you been thinking to get a subscription yet ?
There's really a ton to learn from How to Sound Like, How to Make Full Track and all techniques from Mixing to Mastering which again are applicable to any DAW.
The tutors being mostly established DJ/Producers is another real benefit of S.A content, so IMHO, if you want to access all tutorials & content online, a subscription is really the way to go. S.A have some flexible plans in the duration & honestly the investment is quite cheap regarding the content.
