Abstract: By user's pinching operation on a slider 2e of a controller 2, it is judged that the slider 2e has been operated on two points, so that a DAW screen is zoomed in or out in accordance with the speed at which the distance between the two points has changed and the amount by which the distance between the two points has changed. By user's sliding operation on the slider 2e of the controller 2, it is judged that the slider 2e has been operated on one point, so that the function of the DAW is controlled in accordance with the speed at which the slider 2e has moved and the amount by which the slider 2e has moved.

Abstract: An internal combustion engine is provided with a valve lift varying mechanism for intake valves and a valve phase varying mechanism for exhaust valves. A controller performs a control operation in response to a request to pause at least one cylinder while the engine is in operation. The control operation includes: a first operation of setting an intake valve lift to a zero-lift setpoint by the valve lift varying mechanism; and a second operation of setting an exhaust valve phase by the valve phase varying mechanism so as to set an exhaust valve opening timing to a first timing setpoint on an advance side of bottom dead center and set an exhaust valve closing timing to a second timing setpoint on a retard side of bottom dead center. The first and second timing setpoints are closer to top dead center than to bottom dead center.

Abstract: A system includes at least one controller device connectable to a computer where a mixer function is implemented by application software. The controller device includes: a communication interface connectable to the computer; a plurality of faders capable of remote-controlling parameters of channels assigned thereto; a channel shift button; and a bank shift button. The channels assigned to the faders are collectively shifted by one channel in response to an instruction given via the channel shift button, or collectively shifted by the one bank in response to an instruction given via the bank shift button. For each of the controller devices, identification information of the controller device and information of a first channel of all of the assigned channels is stored so that the stored information is used at the time of activation of the software for restoring previous settings stored at the time of last deactivation of the software.

Abstract: A parameter controlling apparatus has a CPU 201 and operation input portion 302, 303 and 305 which include an operating area 303 whose operated position can be detected, and accept input operation. The CPU 201 detects whether the operation input portion is operated in the first manner or the second manner in accordance with the accepted input operation, and detects the content of the input operation of the operating area 303. In a case where the first manner has been detected, the CPU 201 also changes a value of a target parameter in accordance with the content of the input operation of the operating area 303. In a case where the second manner has been detected, the CPU 201 also switches a type of a target parameter in accordance with the content of the input operation of the operating area 303.

Abstract: Calculation is performed for sound paths 112-1, 114-1 along which sounds emitted from a sound emitting point 104 in an acoustic space 102 are reflected and delivered to a sound receiving point 106. By the calculation, entering angles eR1, eR2 by which the sound paths enter the front side 106a of the sound receiving point 106 are obtained. Calculation is then performed to obtain angles by which respective speakers 52C, 52L, 52R, 52SR, 52SL of a 5.1 surround system are arranged in a listening room, with the front side 106a of the sound receiving point 106 centered thereon. Audio signals on the respective sound paths are distributed among channels for any two speakers. Consequently, sharp localization of sound images is achieved, requiring less calculation in simulating acoustic characteristics of the acoustic space 102 in which the sound emitting point 104 for emitting sounds and the sound receiving point 106 for receiving the sounds are placed.

Abstract: An electronic musical system in which tone generator parameters of each of tone generators respectively assigned to tracks of a sequencer of an electronic musical apparatus can easily be controlled by using a musical control apparatus, while tracks are switched. In the setting of the tone generator parameters of the tone generators assigned to the tracks, setting contents are input by using control operating elements of the musical control apparatus. There are prepared in advance templates in each of which control operating elements are made to correspond to tone generator parameters controlled by the control operating elements, and each tone generator is made in one-to-one correspondence with one of the templates, whereby tone generator parameters of a tone generator assigned to a track currently designated by a user are set by manipulating the control operating elements of the musical control apparatus.

Abstract: An electronic music system includes a computer which performs a sequencing function and a remote controller. The remote controller is provided with a start operator and a selection operator. In response to an instruction made by the start operator of the remote controller, the computer or the remote controller adds a new track on a sequencer configured on the computer. The computer or the remote controller then offers options of available different types of tone generators used for the track, and in accordance with a selection made by the selection operator in a state where the available different types of tone generators have been offered, assigns the selected type of tone generator to the track.

Abstract: In an engine provided with a variable valve mechanism which varies an operating angle of an intake valve and a lift amount thereof, when an engine operation is automatically stopped after the establishment of an idling stop condition, the operating angle of the intake valve and the lift amount thereof are varied to be smaller, so that a load of the variable valve mechanism at an engine operation restarting time is low. Then, when the engine operation restarting is requested, a first explosion pressure is obtained by performing fuel injection and ignition on a cylinder stopped in an expansion stroke, so that the engine operation is started. Further, after a first intake stroke, the operating angle of the intake valve and the lift amount thereof are increased.

Abstract: A parameter management apparatus manages a plurality of parameters provided for control of an externally connected acoustic apparatus. The parameter management apparatus has a storing portion for storing a plurality of parameters stored in the acoustic apparatus. The parameter management apparatus selects, from among the parameters stored in the storing portion and the acoustic apparatus, respectively, at least one parameter for which a match is caused between the storing portion and the acoustic apparatus. The parameter management apparatus then causes exact a match between the at least one parameter stored in the storing portion and the at least one parameter stored in the acoustic apparatus.

Abstract: Filtering is performed on original waveform to remove components of a predetermined frequency band from the waveform, and dividing positions of the original waveform data are determined on the basis of envelope levels of the filtered waveform. The dividing positions may be determined on the basis of differentiation of an envelope of the filtered waveform. Rise positions in the original waveform data are detected, and one rise position may be selected from among one or more rise positions detected within a predetermined range of the original waveform and extracted as a dividing position of the original waveform. Presumed beat positions in the original waveform may be detected, and rise positions of the original waveform may be detected within predetermined ranges corresponding to the presumed beat positions.
