Abstract: 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.
Abstract: Provided is an electronic keyboard, which has a sequentially variable operating terminal, that comprises: a detector for detecting an operational displacement of the sequentially variable operating terminal, a linear converter for converting into a linear value the operational displacement of the sequentially variable operating terminal that is detected by the detector, a linear conversion table that is to be referred to when the linear converter converts the operational displacement into the linear value, a bender MIDI converter for converting into a bender MIDI value the linear value that is obtained by the linear converter, and a bender MIDI conversion table that is to be referred to when the bender MIDI converter converts the linear value into the bender MIDI value; and wherein the bender MIDI converter refers to the bender MIDI conversion table to convert the operational displacement of the sequentially variable operating terminal into a discrete bender MIDI value.
Abstract: An electronic musical tone synthesizing apparatus includes a damper pedal and an envelope generator. The envelope generator imparts an envelope to a musical tone to be produced. When the termination of the musical tone is designated, the envelope generator imparts a decaying envelope thereto. If the damper pedal is depressed during the processing of the decaying envelope, the decaying rate becomes slower. This leads to the performance of sustaining effects such as in an acoustic piano.
Abstract: Novel shapes and interrelationships of interreactive domains for wholetone musical selection devices such as keyboards or other user interface medium are described. Chromatic glissandos are allowed on these devices. Operator choice for ascending or descending one finger slurs using any one of the twelve per octave fingerkeys as slur instigator or slur receptor is optimized. Novel one digit multiple pitch slurs numbering three or four pitches are acheived.
Abstract: A keyboard and a portamento bar are connected to a tone generator through a common channel assigner to use each tone generating channel either for generating a keyboard sound or for generating a portamento sound. Thus, a portamento sound can be generated without a need for providing a another tone generator. Further, such arrangement is provided that can shift the tone generation from a keyboard sound to a portamento sound and from a portamento sound to a keyboard sound, enabling initiation and termination of a portamento performance to have accurate pitches.
Abstract: An electronic keyboard percussion instrument includes a hammer such as a mallet, a plurality of plates, striking detection devices, and a musical tone generating section. The plates respectively correspond to note names of musical tones to be produced and aligned parallel to each other. The striking detection devices are respectively mounted on lower surfaces of the plates to detect striking of the plate with the mallet and to generate a striking detection signal. The musical tone generating section generates a musical tone of the note name corresponding to the struck plate in response to the striking detection signal. The striking detecting section may include a pressure sensitive element in order to make the musical tone responsive to a force striking the plate.
