Musical sound generating apparatus and musical sound generating method

Abstract

A musical sound generating apparatus capable of improving the sensitivity of pressing against a percussion surface is provided. The musical sound generating apparatus includes a percussion surface, a pressure sensor disposed on the percussion surface on a side of a back surface and configured to detect a pressure change, an elastic body compressed between the percussion surface and the pressure sensor, and a control device configured to output an instruction according to an output value of the pressure sensor, and the control device includes a pressing detection unit configured to detect pressing against the percussion surface on the basis of a difference between the output value of the pressure sensor and a reference value, and an updating unit configured to update the reference value at every updating time according to the output value of the pressure sensor.

Dependencies are inferred from the claim text.
