CONDTIONALS

So, let’s flip a coin: if it’s heads, play a drum, if it’s tails, play a cymbal. Easy. We can emulate a coin flip with our one_in function (introduced in the section on randomness) specifying a probability of 1 in 2: one_in(2). We can then use the result of this to decide between two pieces of code, the code to play the drum and the code to play the cymbal: 

loop do

  if one_in(2)
    sample :drum_heavy_kick
  else
    sample :drum_cymbal_closed
  end
  
  sleep 0.5
  
end
