Digital pianos typically use analog sensors for its keyboard action, as opposed to digital sensors of a regular keyboard and synthesizer. These sensors notably works in a similar way to those used in analog joysticks found on video game controllers, in which they the velocity input is converted from the key movement as well, not just the initial pressure of the key sensor.
Chords are not used that often by electric bass players. However, in some styles, bassists may sound "double stops", such as octaves with open strings and powerchords. In Latin music, double stops with fifths are used. Robert Trujillo of Metallica is known for playing "massive chords"  and "chord-based harmonics"  on the bass. Lemmy of Motörhead often played power chords in his bass lines.
Drums are used not only for their musical qualities, but also as a means of communication over great distances. The talking drums of Africa are used to imitate the tone patterns of spoken language. Throughout Sri Lankan history drums have been used for communication between the state and the community, and Sri Lankan drums have a history stretching back over 2500 years.
