Patent number: 7521623Abstract: The invention generally pertains to a hand-held computing device. More particularly, the invention pertains to a computing device that is capable of controlling the speed of the music so as to affect the mood and behavior of the user during an activity such as exercise. By way of example, the speed of the music can be controlled to match the pace of the activity (synching the speed of the music to the activity of the user) or alternatively it can be controlled to drive the pace of the activity (increasing or decreasing the speed of the music to encourage a greater or lower pace). One aspect of the invention relates to adjusting the tempo (or some other attribute) of the music being outputted from the computing device. By way of example, a songs tempo may be increased or decreased before or during playing. Another aspect of the invention relates to selecting music for outputting based on tempo (or some other attribute). For example, the computing device may only play songs having a particular tempo.Type: GrantFiled: November 24, 2004Date of Patent: April 21, 2009Assignee: Apple Inc.Inventor: Adam Bowen

Patent number: 6232540Abstract: A time-scale modification method or apparatus is basically designed to effect a time-scale modification process (i.e., expansion or compression with respect to time) on rhythm source signals containing waves such that rhythm sounds are not substantially changed in pitches. Herein, attack positions are detected from the rhythm source signals by using thresholds which are determined in advance. Hence, the time-scale modification process is performed on intermediate signal portions of the rhythm source signals between the attacks in accordance with a desired time-scale modification factor. Then, the intermediate signal portions subjected to the time-scale modification process are smoothly connected with other signal portions such as the attacks and their proximal portions, which are not subjected to the time-scale modification process.Type: GrantFiled: May 4, 2000Date of Patent: May 15, 2001Assignee: Yamaha Corp.Inventor: Kazunobu Kondo

Patent number: 6118065Abstract: As automatic performance data are sequentially supplied at a given tempo, a player sequentially depresses keyboard keys at appropriate timing. Comparison is made between timing of each manual key-on event and timing of key-on and key-off events of each automatic performance note in the performance data. If key-on timing of a given automatic performance note is within a predetermined allowable difference from given manual key-on timing, a tone based on the given automatic performance note is generated at a time corresponding to the manual key-on timing. If key-off timing of a given automatic performance note is within another predetermined allowable difference from given manual key-on timing and if a tone based on the note has not yet been generated, that tone is generated at timing corresponding to the manual key-on timing.Type: GrantFiled: February 19, 1998Date of Patent: September 12, 2000Assignee: Yamaha CorporationInventor: Kazuo Haruyama

Patent number: 5952596Abstract: A pitch/tempo converting apparatus is constructed for concurrently changing a tempo and a pitch of an audio signal according to tempo designation information and pitch designation information. In the apparatus, a memory section memorizes the audio signal composed of original amplitude values sequentially sampled at original sampling points timed by an original sampling rate within an original frame period. A tempo converting section converts the original frame period into an actual frame period by varying a length of the original frame period according to the tempo designation information so as to change the tempo of the audio signal. A pitch converting section converts each of the original sampling points into each of actual sampling points by shifting each of the original sampling points according to the pitch designation information so as to change the pitch of the audio signal.Type: GrantFiled: September 15, 1998Date of Patent: September 14, 1999Assignee: Yamaha CorporationInventor: Kazunobu Kondo

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.

Patent number: 5648627Abstract: A performance control apparatus is provided to control a manner of performance played by an electronic musical apparatus. Herein, sensors are provided to sense a swing motion of a baton which is swung by a human operator in response to time of music to be played (e.g., triple time). Then, a peak is detected from outputs of the sensors in accordance with a peak detection process using a fuzzy inference process. A kind of the swing motion is discriminated by effecting another fuzzy inference process on a result of the peak detection process. Concretely, the kind of the swing motion is discriminated as one of predetermined motions which are determined specifically with respect to time of the music. Performance control information is created based on the discriminated kind of the swing motion. Thus, a tempo and/or dynamics of performance is controlled in response to the performance control information.Type: GrantFiled: September 20, 1996Date of Patent: July 15, 1997Assignee: Yamaha CorporationInventor: Satoshi Usa

Patent number: 5585584Abstract: An automatic performance control apparatus provides a hand controller which contains gyro sensors in X, Y directions. The gyro sensors are employed to accurately detect hand-swing motion applied to the hand controller without being affected by gravity. When the hand controller is swung by a human operator like a conductor's baton, angular velocity applied to the hand controller is detected based on detection values of the gyro sensors. The angular velocity becomes bottom at a change point of direction in a locus of the hand-swing motion of the hand controller; and a peak of the angular velocity appears between bottoms. So, peak detection process is performed on the angular velocity to determine a beat timing designated by the human operator. If the peak is detected, beat-timing detection data are automatically created and are transmitted to an electronic musical instrument having an automatic performance function.Type: GrantFiled: May 6, 1996Date of Patent: December 17, 1996Assignee: Yamaha CorporationInventor: Satoshi Usa

Patent number: 5227574Abstract: When a tap switch is operated at desired beats during automatic music play, the tempo of the automatic play is variably controlled in correspondence with the interval between the tap operations. On the other hand, detection is made of a difference between the current score time at a tap switch operation time and the score time of a beat point corresponding to the tap switch operation time. Then, control is made for progressively changing the current score time in order to eliminate the detected score time difference. Thus, the score time difference is progressively eliminated in smooth manner, so that necessary notes can be sequentially sounded without being left out. The control for progressively changing the current score time may be performed in accordance with a predetermined function. Further, the control for progressively changing the current score time may be performed with a characteristic such that it is automatically changed in view of the number of notes in the automatic play.Type: GrantFiled: September 24, 1991Date of Patent: July 13, 1993Assignee: Yamaha CorporationInventor: Hirofumi Mukaino
