Good Tutorials?

I´m just testing the Demo version. But I don’t get along at all. Are there any good tutorials in the web?

Go to YouTube and search Spectralayers version 4, then v5 and v6. There are a few giving some basic operations. And there is s Groove3 SL v3 tutorial. On sale, last night tonight for $8. The only thing about v3 is that the menus have changed, and some of the preferences/processes/sliders to adjust different aspects of the spectrum have changed. And v3 was standalone. Hopefully some new tutorials on how to use SLv6 ARA2 in Cubase 10 will be coming out.
