The best advice: Go listen to a lot of future bass!
No, really. Go find 10 future bass songs that you absolutely adore, pull one into your DAW and start deconstructing it. Open up a soft synth and try to copy their exact chord progression. It might take some work to find the exact voicing but you should start to see the idea. Hell, see if you can pick out all the different elements of the song and mark them down with empty MIDI clips. Mark down the arrangement sections (Intro/Chorus/Breakdown/etc), set the BPM to be the same as the track, and see if you can "recreate" the song out of empty tracks and clips.
Now do that for the other 9 songs, and you'll know more about future bass than anyone on this forum could ever explain to you in a post.
