Patent ID: 7078610

Claim:
An electronic percussion instrument comprising: a plurality of pads; waveform input means with which the waveforms are input; first storage means with which the waveforms that are input by the waveform input means are stored; waveform assignment means with which the waveforms that are stored by the waveform storage means are respectively assigned to the plurality of pads; musical tone generation means with which, when a pad to which a waveform has been assigned is struck, a musical tone is generated based on the waveform that has been assigned to the pad; waveform identification code assignment means with which a waveform identification code is assigned to the waveform that is input by the waveform input means; and first retrieval means that retrieves unused waveform identification codes; wherein the first storage means stores the waveform that is input in association with the waveform identification code that has been assigned to that waveform; wherein the first storage means stores the waveform identification code in association with one of the plurality of pads to assign the waveform to a pad; and wherein the waveform identification code assignment means assigns an unused waveform identification code to the waveform that is input.
