Patent number: 5990405Abstract: A musician can simulate participation in a concert by playing a musical instrument and wearing a head-mounted 3D display that includes stereo speakers. Audio and video portions of a musical concert are pre-recorded, along with a separate sound track corresponding to the musical instrument played by the musician. Playback of the instrument sound track is controlled by signals generated in the musical instrument and transmitted to a system interface box connected to the audio-video play back device, an audio mixer, and the head-mounted display. An external bypass switch allows the musician to suppress the instrument sound track so that the sounds created by actual playing of the musical instrument are heard along with the pre-recorded audio and video portions.Type: GrantFiled: July 8, 1998Date of Patent: November 23, 1999Assignee: Gibson Guitar Corp.Inventors: Don R. Auten, Richard T. Akers, Richard Gembar

Patent number: 5952597Abstract: The invention relates to a computerized method for correlating a performance, in real time, to a score of music, and a machine based on that method. A score processor accepts a score which a user would like to play and converts it into a useable format. Performance input data is accepted by the input processor and the performance input data is correlated to the score on a note-by-note basis. An apparatus for performing this method includes an input processor that receives input and compares it to the expected score to determine whether an entire chord has been matched, and an output processor which receives a note match signal from the input processor and provides an output stream responsive to the match signals.Type: GrantFiled: June 19, 1997Date of Patent: September 14, 1999Assignee: TimeWarp Technologies, Ltd.Inventors: Frank M. Weinstock, George F. Litterst

Patent number: 5952599Abstract: An improved music generation system that facilitates artistic expression by non-musician and musician performers in both individual and group performance contexts. Mappings are provided between 1) gestures of a performer as indicated by manipulation of a user input device, 2) displayed motion of a graphic object, and 3) global features of a musical segment. The displayed motions and global features are selected so as to reinforce the appearance of causation between the performer's gestures and the produced musical effects and thereby assist the performer in refining his or her musical expression. The displayed motion is isomorphically coherent with the musical segment in order to achieve the appearance of causation. The global features are segment characteristics perceivable to human listeners. Control at the global feature level in combination with isomorphic visual feedback provides advantages to both non-musicians and musicians in producing artistic effect.Type: GrantFiled: November 24, 1997Date of Patent: September 14, 1999Assignee: Interval Research CorporationInventors: Thomas Dolby, Tom Dougherty, John Eichenseer, William Martens, Michael Mills, Joy S.

Patent number: 5905223Abstract: A signal processor acts upon a stream of incoming musical performance data including note-on signals and outputs a stream of musical performance data including note-on and note-off signals. The incoming performance data is dispatched to a multiplicity of output channels depending on the time interval between successive incoming note-on data. Notes played in very rapid succession are identified as chords and are performed with identical musical parameters such as duration and instrumental timbre. Notes played in slow succession are identified as polyphonic and are performed with the same instrumental timbre. Notes played at an intermediate speed are identified as melodic and are performed with the same instrumental timbre and a variable staccato or legato effect.Type: GrantFiled: November 12, 1997Date of Patent: May 18, 1999Inventor: Mark Goldstein

Patent number: 5880388Abstract: A first reading unit reads first performance data from a first storage medium, and outputs it to a reproducing unit. A second reading unit reads second performance data from a second storage medium, and outputs it to the reproducing unit. The reproducing unit reproduces the first performance data inputted from the first reading unit, and the second performance data inputted from the second reading unit. A control unit synchronizes reproduction of the first performance data and reproduction of the second performance data, and switches between these reproductions.Type: GrantFiled: March 5, 1996Date of Patent: March 9, 1999Assignee: Fujitsu LimitedInventors: Ryo Kajiyama, Seiji Tsutsui, Hitoshi Sakazume, Yukikazu Emori

Patent number: 5880391Abstract: The controller scans a plurality of chord switches which select a particular type of chord. If a previously operated selection switch is still closed, the previously generated MIDI chord message continues. If a selection switch is newly operated, then the MIDI signals from an associated musical instrument on a selected channel are scanned to determine the presence of a particular note meeting pre-selected criteria. When such a note is recognized, a three-note MIDI chord message using the particular note as the root note in the chord is produced and transmitted to the music sequencer, which produces a musical pattern in the particular chord as an accompaniment to the musical instrument.Type: GrantFiled: November 26, 1997Date of Patent: March 9, 1999Inventor: Robert L. Westlund

Patent number: 5877445Abstract: A block sequence compiler for compiling a sequence of audio and/or video blocks (e.g., audio tracks, MIDI, video clips, animation, etc.) suitable for producing one or more audio and/or video output sequences (i.e., audio, video, or multimedia) each having a duration corresponding to user-prescribed criteria. In a preferred embodiment, a user chooses an audio and/or video source segment from a predefined library and prescribes the duration of an audio and/or video sequence. Prior to depositing each audio and/or video segment in the library, the segment is partitioned into audio and/or video blocks that are identified in a corresponding characteristic data table with characteristics including (1) duration, (2) suitability for being used as a beginning or ending of an audio and/or video sequence, and (3) compatibility with each block. Using this characteristic table and the user-prescribed criteria, i.e.Type: GrantFiled: October 24, 1997Date of Patent: March 2, 1999Assignee: Sonic Desktop SoftwareInventors: Geoffrey Calvin Hufford, Christopher P.

Patent number: 5866833Abstract: Automatic play progresses automatically with each sound generating operation based on timing data that indicates the timing for sounding a tone. In this manner, performance information for time count automatic play can be used with one-step automatic play. In addition, the information based on the tone generation operation for one-step automatic play and the information based on the sound generating operation for manual play are assigned to tone generating channels, which enables one-step automatic play and manual play to be performed together (in soli). Also, whether or not one-step automatic play is performed can be selected for each respective performance part or instrumental part.Type: GrantFiled: May 31, 1996Date of Patent: February 2, 1999Assignee: Kawai Musical Inst.
