Absement

We present a musical keyboard that is not only velocity-sensitive, but in fact responds to absement (presement), displacement (placement), velocity, acceleration, jerk, jounce, etc. (i.e. to all the derivatives, as well as the integral, of displacement).

Mathematical parallelisms between mem-dashpots and mem-springs were recognized and exploited, but physical differences and the newness of mem-springs led to the realization that these newer models deserve deeper study, in part because of a little-studied quantity called absement which allows mem-spring models to display hysteretic response in great abundance.
