Electronic percussion instrument, electronic musical instrument, information processing device, and information processing method

An information processing device for an electronic musical instrument comprising a first playing operation element and a second playing operation element, the information processing device comprising:

• a control device that performs a process of generating an envelope indicating a change in a reference value over time based on a waveform that indicates vibration of the first playing operation element,
• wherein the reference value is for determining whether vibration of the second playing operation element is self-induced vibration or excited vibration entailed by the vibration of the first playing operation element,
• wherein when the vibration of the second playing operation element is determined by the reference value, the control device performs a process of preventing first information on a basis of the excited vibration of the second playing operation element from being included in second information that indicates the self-induced vibration of the second playing operation element through using the reference value indicated by the envelope.
