Transposer, that is keyboards put on the piano’s keyboard, doesn’t produce any sound. This device only helps a musician to play a piece of music with the same fingering and it is not very popular among musicians.
Modifications of piano keys, of course, are not instruments in direct sense. But they help to understand work and construction principles of keys and hammers mechanics.
