In a music reproduction apparatus designed for a listener to enjoy music
while experiencing variations in vehicle status, plural types of phrases,
which differ from each other, are assigned to plural tracks and are
reproduced in accordance with reproduction parameters, which are
controlled in response to vehicle status information. It is possible to
control the setup values of reproduction parameters suiting vehicle
statuses in response to travel environments. In addition, it is possible
to synchronize the reproduction start timing of a music reproduction unit
corresponding to one measure being reproduced by a first track with the
reproduction start timing of a music reproduction unit corresponding to
plural measures being reproduced by a second track. In a music
information distribution system, a server stores music files including
reproduction parameters suiting vehicle statuses and travel environments,
so that the music reproduction apparatus reads them so as to reproduce
corresponding musical tunes.
