Claim:
A musical tone control device for an electronic percussion musical instrument that has a striking surface with a moveable striking surface position, the musical tone control device comprising: a position information acquisition device that obtains striking surface position information corresponding to the striking surface position; a strike information acquisition device that obtains strike information indicating that the striking surface has been struck; a musical tone generation instruction device that, when strike information is obtained by the strike information acquisition device, provides instructions for a sound source to generate a musical tone with a timbre corresponding to the striking surface position information obtained by the position information acquisition device, the musical tone generation instruction device providing instructions for the sound source to generate a musical tone with a first timbre when the striking surface position information corresponds to the striking surface position being within a predetermined range, where the predetermined range includes at least a first position; a musical tone stop instruction device that provides instructions for the sound source to stop a musical tone being generated, when the striking surface position information obtained by the position information acquisition device corresponds to the striking surface position being the first position; and a transition state information acquisition device that obtains information relating to a transition state of the striking surface position, based on the position information obtained by the position information acquisition device, after the musical tone generation instruction device provides instructions to generate a musical tone with the first timbre; wherein, when the striking surface position information obtained by the position information acquisition device corresponds to the first position, the sound source stop instruction device provides instructions for the sound source to stop generating a musical tone with the first timbre, in response to information obtained by the transition state information acquisition device that corresponds to the striking surface position reaching a predetermined second position higher than the first position after the musical tone generation instruction device provided instructions for generating the musical tone.
