  • Patent number: 5324882
    Abstract: A tone generating apparatus that employs a read-out system comprises a waveform memory wherein are stored, as waveform data for a transient portion, waveform data that have a weighted attenuation characteristic and that are stored at a predetermined interval within a stationary portion following a rising portion of the musical tone, and waveform data that are obtained by extracting and linking multiple sets of the waveform data at the predetermined interval within a stationary portion, by filtering the resultant waveform data by employing a filtering process that does not alter phase information, by extracting from filtered waveform data waveform data for an interval equivalent to the predetermined interval, by linking together the extracted waveform data in numbers equivalent to the number of waveforms included in the predetermined interval, and by weighting the resultant waveform data with a rising characteristic; and wherein are further stored, as waveform data for a repetitive portion, the filtered wavefo

  • Patent number: 5319152
    Abstract: A chord information output apparatus according to the present invention includes a keyboard, a key depression information detector, a chord detector for detecting a chord according to key information detected by the key depression information detector, and an internal information output section for sending detected chord information to an external device. The chord information output apparatus detects a chord upon keyboard key depression, and outputs the chord as chord information to an external device.

  • Patent number: 5298677
    Abstract: An automatic playing apparatus according to the present invention, stores, in an automatic playing pattern data memory, chord, bass, drum data for each of a plurality of intro, normal and ending patterns, and drum data for each of a plurality of fill-in patterns, and reads, when a fill-in is selected via an operation panel, chord data and bass data, stored for an intro, normal, or ending pattern data, and drum data, stored for a fill-in pattern, to perform automatic playing. Further, an automatic playing apparatus according to the present invention includes an automatic playing pattern data memory wherein loud fill-in pattern data and soft fill-in pattern data are stored, sets an intonation value using an intonation dial as the performance is developed, and performs automatic playing based on either loud fill-in pattern data, if the intonation value is equal to or greater than a predetermined value, or based on the soft fill-in pattern data, if the intonation value is smaller than the predetermined value.

  • Patent number: 5250746
    Abstract: Disclosed are a chord detecting/storing apparatus and an accompaniment information processing apparatus. The chord detecting/storing apparatus designates tones consisting of a chord on a keyboard, and extracts one of the designated notes. Based on the extracted note, the apparatus prepares a row of note bits excluding at least one note. Using this note bit row as an address, the apparatus searches for a chord table in advance where chord information is stored to correspond to each pattern for a row of note bits, and reads out searched chord information to detect a chord.The accompaniment information processing apparatus detects component tones of a chord when the chord is designated from the keyboard, and generates chord information. The accompaniment information processing apparatus produces specific tone information in association with the generated chord information and correlates the specific tone information with the chord information before storing both information items.
