From my first attempt at live coding, at the SwiftKey music night.

live_loop :tick do
  root, type = [[:d4,:m7],[:g4,:dom7],[:c4,:M7],[:f4,:M7],[:b4,:'m7+5'],[:e4,:dom7],[:a4,:m7]].tick(:tick)
  cue :boom, root: root, type: type
  with_fx :reverb, amp: 2 do
    sample :drum_cymbal_closed, amp: 3
    sleep 0.5
    3.times do
      sample :drum_cymbal_closed
      sleep 0.5
    end
    uncomment do
      sample :drum_cymbal_closed, amp: 2
      sleep 0.5
      3.times do
        sample :drum_cymbal_closed
        sleep 0.5
      end
    end
  end
end

live_loop :tock do
  sync :tick
  uncomment do
    if bools(1, 0).tick(:tock) then
      sample :drum_bass_hard, amp: 2
      sleep 1
    else
      sample :drum_bass_hard, amp: 2
      sleep 0.5
      sample :drum_bass_hard, amp: 2
      sleep 0.5
    end
    if one_in(4) then
      sample :drum_cymbal_open
    else
      sample :drum_snare_hard
    end
    sleep 1
  end
end

live_loop :buzz do

  uncomment do
    with_fx :ixi_techno do
      with_synth :prophet do
        play chord(data[:root],data[:type]), decay: 3
      end
    end

end

          s = chord(n, data[:type])
          play_pattern_timed s.shuffle[0..3], 0.25, amp: 0.7
