Best way to toggle between 2 different live_loops

Here’s an example controlling three live loops which can independently be stopped and started.
This is done by embedding each loop in a function, and using that to control a stop command inside each loop

use_synth :tri

define :lone do |action|
  if action==1
    set :k1,false
    live_loop :one do
      play scale(:c5,:minor_pentatonic).choose,release: 0.1
      sleep 0.1
      stop if get(:k1)
    end
  else
    set :k1,true
  end
end

define :ltwo do |action|
  if action==1
    set :k2,false
    live_loop :two do
      
      play scale(:g5,:minor_pentatonic).choose,release: 0.1
      sleep 0.1
      stop if get(:k2)
    end
  else
    set :k2,true
  end
end

define :lthree do |action|
  if action==1
    set :k3,false
    live_loop :three do
      play scale(:c6,:minor_pentatonic).tick,release: 0.1
      sleep 0.1
      stop if get(:k3)
    end
  else
    set :k3,true
  end
end


live_loop :control do
  puts "start live_loop :lone"
  lone 1
  sleep 4
  puts "stop live_loop :lone"
  puts "start live_loop :ltwo"
  lone 0
  ltwo 1
  sleep 4
  puts "stop live_loop :ltwo"
  puts "start live_loop :lthree"
  ltwo 0
  lthree 1
  sleep 4
  puts "ADD live_loop :lone"
  lone 1
  sleep 2
  puts "ADD live_loop :ltwo"
  ltwo 1
  sleep 4
  puts "stop live_loop :one"
  puts "stop live_loop :ltwo"
  puts "stop live_loop :lthree"
  lone 0
  ltwo 0
  lthree 0
  sleep 2
end
