do
  let bars = 4
      key = "8"
      righthand = "[[4 -3] [0 _ _ _ _ _ 0]] [[-3, -8] [7 5 4 0]]"
      lefthand = "[0 9 12 16] [4 12 16 19] [5 12 17 19] [2 12 17 16]"
  d1 $ slow bars
     $ stack [
         n (righthand + key + "<24 36>/2"),
         n (lefthand + key)
       ]
     # s "midi"
     # octave "3"
     # velocity "0.3 0.5 0.8 0.9"
     # sustain "[2 0.7]*4"

so what would be [[4 -3] [0 _ _ _ _ _ 0 ]] vs [4 -3 0 0] ?
I assume "_" is a rest. are the duration values based on size of the array? i.e. for an array [0, 1, 2, ... , n] each note would get a duration of 1/n.
And then what is the difference between [a b] and [a, b]

Note: To get this working locally after installing TidalCycles follow the SuperDirt MIDI Tutorial to define a MIDI Out for SuperCollider named midi.

In my case I defined MIDI Out to point to a VIRTUAL MIDI-Out Host running on my laptop. I was then able to receive MIDI events over Web MIDI and play audio via Web Audio in a browser. :)
