  2. Ventils for Mixtures (Llenos) (Cavaillé-Coll Appel)
  3. Double length trumpets (Cavaillé-Coll Trompette Harmonique).
  4. Expression slots (only used by Cavaillé-Coll from 1857 on after he had completed his famous instrument in Saint Denis).
  5. Imitation of Transverse Flute.
  6. Placement of entire manual in the swell box.
  7. Adjustable couplers.
  8. Elaborate playless Stop action, pre-tensed, so as to only allow a pulling motion by substituting/neutralizing any pushing movement.
  9. Rollerboard pins suspended by springs, thereby avoiding a false touch.
  10. System for muffling unnecessary noise due to action.
  11. Concentrated use of steel structures to save space.
  12. Wind supply system using connecting rods with counter weights.
  13. Triple wind box (Cathedral of Seville 1793)

  15. Horizontal bellows (perhaps the Cathedral of Seville 1793).
