An electronic percussion instrument and a method of detecting a percussion position are provided. The percussion position in a left-right direction is calculated by comparing an added-up value of output values of a first edge sensor with an added-up value of output values of a second edge sensor. Compared with a case where peak values of the first and second edge sensors are used, it is possible to make a great difference between an added-up value in a case where the vicinity of the first edge sensor (the second edge sensor) is percussed and an added-up value in a case where a position away from the first edge sensor (the second edge sensor) is percussed.

Electronic percussion instrument and method of detecting percussion position

Provided is an electronic musical instrument comprising: an input device for inputting sound generation instructions of tones at predetermined pitches; a tone generation device that generates tones with predetermined pitches based on sound generation instructions inputted by the input device; a specifying device that specifies a plurality of sound generation instructions inputted by the input device in a predetermined period as a sound generation instruction group; a sorting device that sorts the plurality of sound generation instructions composing the sound generation instruction group specified by the specifying device in a predetermined pitch order; and a control device that controls generation of tones by the tone generation device such that tones corresponding to the sound generation instruction group are generated in the order sorted by the sorting device.

Sorting a plurality of inputted sound generation instructions to generate tones corresponding to the sound generation instruction in a sorted order

Provided are an electronic musical instrument, computer storage device, and method for generating tone. A sound source in an electronic musical instrument generates a first tone at a first pitch in response to a first tone generation instruction received by an input device of the electronic musical instrument. A second tone generation instruction is received to generate a second tone at a second pitch while generating the first tone at the sound source. A determination is made of a pitch difference of the first and the second pitches. The sound source is controlled to generate the second tone and to not generate the first tone in response to determining that the pitch difference does not exceed a predetermined number of tones. The sound source is controlled to generate the second tone in response to determining that the pitch difference exceeds the predetermined number of tones.

Electronic musical instrument to generate musical tones to imitate a stringed instrument

Provided are a tone control device and a method for adjusting a volume level at which to generate a new tone and at least one current tone according to a target volume level and a current volume level. A note-on event associated with a received volume level is received from an input device. A current volume level is processed to determine a new volume level in response to receiving the note-on event while generating at least one current tone at the current volume level. The at least one current tone and a new tone associated with the received note-on event are generated at the new volume level.

Adjusting a level at which to generate a new tone with a current generated tone

Provided are an electronic musical instrument, computer storage device, and method generating tones for held notes. Indication is made of held notes having pitches as held in response to receiving note-on information for the held notes from an input device of an electronic musical instrument while receiving hold information from a hold device of the electronic musical instrument. Note-on information is received for a received note having a pitch while generating the pitches for the held notes. Selection is made of one of the held notes to release according to a first selection criteria in response to determining that the pitch difference of the received note and at least one of the held notes does not exceed the predetermined number of tones or selection is made according to a second selection criteria if the pitch difference exceeds the predetermined number of tones.

Electronic musical instrument

Provided are a method, computer storage device, and tone control device for generating tones with a vibrato effect. A determination is made of a key depression interval comprising a difference of a current time of a current note from a previous time of a previous note. A performance mode is set to a single tone mode, in which only one note is generated, or a polyphonic mode, in which multiple notes are simultaneously generated, based on the determined key depression interval. The tone is generated to output the current note with a first modulation magnitude in response to determining that the performance mode is the single tone mode. A tone is generated to output the current note with a second modulation magnitude in response to determining that the performance mode is the polyphonic mode, wherein the first modulation magnitude is greater than the second modulation magnitude.
