The instrument was configured to provide a keyboard full of ‘animals’, from lions in the lowest octave, to twittering birds in the highest. Of these sounds, only the KOOKABURRA was obtained by ‘sampling’ a recording of a real bird (actually it was a Lyre Bird imitating a Kookaburra!) (PAGE 8); the LION, SQUAWKING BIRD and TWITTERING BIRDS are all modulations of a human voice.
