摘要： A tone waveform reproduction apparatus, for an electronic musical instrument employing a plurality of samples in consonance with tone ranges, that can reduce a change in a timbre so that it will not be noticeable, and that can provide a natural transition of musical tones. An address generator generates a read address for a waveform memory. In the waveform memory are stored waveform data that differ for each timbre and each specific pitch range. A digital filter has a low-pass property and is controlled by a cutoff controller to adjust a timber or a tone quality. The cutoff controller generates a cutoff control signal for compensating for a discontinuity, at a point where tone ranges are switched, of reproduced frequencies of tone signals extracted from the waveform memory, and outputs the cutoff control signal fcn.

摘要： In an electronic musical instrument, playing data are produced by depressing a key in a keyboard, and divided into plural groups. At least one of the semi-automatic playing channels processes sound data of a musical piece read out of a memory to generate musical tones in synchronism with the playing data of at least one group. The sound data may be corrected according to sound correcting data before being used to generate musical tones.

摘要： An electronic keyboard or similar electronic musical instrument having an automatic rhythm playing function and an ad-libbing function. The instrument includes keys to which an ad-libbing function is assigned. When one presses any of the ad-libbing keys on the keyboard, the instrument allows the operator to feel as if the operator were performing an ad-lib. Various kinds of ad lib plays are available by looping note data representative of a single melody or by transforming the note data to a plurality of melodies by chord detection.

摘要： An electronic musical instrument capable of reporting a sound level and a tempo to be set. When a particular sound level or a particular tempo is selected and set, a click having a particular pitch matching the sound level or the tempo is generated to allow the user to recognize the sound level or the tempo on the basis of the pitch of the click. The instrument has a right and a left loudspeaker and, when the sound level is high or the tempo is fast, produces louder sound from one of the loudspeakers while, when the sound level is low or the tempo is slow, producing louder sound from the other loudspeaker.
