features in operating environment of mobile phones such as allowing distribution of arbitrary melodies with voices. On the other hand, Wave Table synthesizer can pronounce the voice built in ROM and arbitrary ADPCM/PCM voices from sequencer by the download of the melody with voices etc.. YMU765 has a built-in hardware sequencer that helps to realize a plex play without heavily loading the host CPU. In addition, it is possible to create more highly efficient applications by the voice synthesis function (- ) and the function of time-variant low pass filter. Moreover, the device also has a built-in circuit for controlling vibrators and LEDs synchronizing with play of music.
