Abstract:
1. A vehicular audio apparatus comprising: a detection device that detects a state of a vehicle; a storage section storing ensemble data representative of an ensemble, the ensemble data including at least first part data indicative of a first performance part of the ensemble and a second part data indicative of a second performance part of the ensemble, a first output condition indicative of a first operating condition of the vehicle being associated with the first performance part while a second output condition indicative of a second operating condition of the vehicle is associated with the second performance part; and a tone generation device that generates a tone of the first performance part on the basis of the first part data when the state detected by said detection device meets the first output condition, but generates a tone of the second performance part on the basis of the second part data when the state detected by said detection device meets the second output condition, wherein, when the state detected by said detection device meets both the first output condition and the second output condition, said tone generation device generates the tones of the first performance part and the second performance part in parallel with each other to inform a vehicle operator as to the state of the vehicle based on the performance parts generated in parallel with each other, wherein said tone generation device includes a timer clock for outputting a timing signal, and, when the tones of the first performance part and the second performance part are to be generated in parallel with each other, said tone generation device generates the tones of the first performance part and the second performance part in a synchronized fashion at a same beat in response to a change of the timing signal, wherein the ensemble data includes a series of event data instructing controlling of tone generation of the first and second performance part, wherein said vehicular audio apparatus further comprises a storage device that stores a table defining correspondency between possible traveling speeds of the vehicle and modulation parameters, wherein the detection device detects a traveling speed of the vehicle as a state of the vehicle, and wherein the tone generation device generates a tone based on the ensemble data stored in said storage section, with reference to the table stored in said storage device, with a musical key designated by the modulation parameter corresponding to the traveling speed of the vehicle detected by said detection device.
