Hey there @darkmetal
Sorry to read that this course didn't match your expectations, there's been very controversial comments about this course, people seems to love it or hate it. For myself I think it's a great course about the production of this track. Even if not going into all the details & sound design to get that sound, the insights about the different parts & the way they are mixed & arranged together to produce the full track was interesting, but of course this is my very own opinion on the course.
If you're interested in Synthwave music, maybe you can have a watch to the Timecop83 course & also interview.
