Re: Any Good Tutorials?
Well, none of your examples are really ambient or downtempo, so if you're looking for tutorials stay away from that. You'd be better off looking up neo-soul/neo-R&B, trap, "chillwave", etc.
A lot of the synths and basses you'd want to use are probably going to be more along the lines of trap, but more on the mellow side if you get me.
Deep sub basses and synths with a decent amount of reverb and what-not.
Definitely search up some things on youtube, like how to make pluck synths and good sub basses. I'd link to some of the tutorials that have helped me the most but I can't yet.
I've experimented with this style a little bit and it's easy once you get the idea of how to make the synths you're after. Also, try using "real" instruments instead of just synths. Harps are rad, asian instruments have a specific but cool sound, acoustic guitars can have a really nice sound, etc.
Lastly, just listen to a shit load of that type of music. But listen critically. Think about how the separate synths sound and all that and just fuck around until you get what you're going after. You won't master it with a couple tutorials over night, so be patient.
Hope this helped a little bit.
