摘要： 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. In parallel with reproduction of automatic performance, waveform data are stored in memory along with synchronization control data indicative of relationship in processing timing between the automatic performance and the waveform data.

摘要： 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.

摘要： An electronic musical instrument includes an ROM which stores tone color parameters for determining musical tone characteristics of musical tone signals. Operating elements are operated to create operation information for controlling the musical tone characteristics on real time basis. A tone generator circuit generates the musical tone signals, based on the cone color parameters read from the ROM and the operation information created by the operating elements. Scene memories and a RAM store the operation information created by the operating elements. The operation information is read from the scene memories or the RAM, in response to an instruction from the operator. The operation formation thus read is supplied to the tone generator circuit.

摘要： The intake flow velocity near the jet of a fuel injection valve is obtained on the basis of the engine rotational speed, engine intake air quantity and intake valve opening area. A crank angle position for maximum intake flow velocity is set as the timing for completion of fuel injection by the fuel injection valve. As a result, fuel injection can be reliably completed at a timing giving good fuel atomization characteristics.

摘要： 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.

摘要： 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.

摘要： 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.
