I decided to record 30 minutes of work from scratch so you guys can see my process. Enjoy, and leave all your questions in the comments bellow and I'll answer them.
MAIN SECTIONS:
0:00-1:40 getting a good lead sound
1:40-3:37 writing the base melody
3:37- about 8:00 tweaking and arranging unimportant
8:47-11:54: making 808 line
11:54- about 26:07: building the drums/beat
26:07-28:57: arranging the intro/structure
29:00 onwards: just messing around and finishing up, less important
Skip to about 35:05 for full beat
