Melodic House sounds sound design help?

Very new to the forum here, as well as to both music production and sound design. Just wanna know, how can I create melodic house sounds ( basses, leads, arps ) in the style of Lane 8, Sultan + Shepard, Attlas, etc?

The sounds sound so warm and simple, but there aren’t many tutorials/ explanations showing how to recreate them.

Any help would really mean a lot!

Thank you!
