Melody sound generating apparatus

DETAILED DESCRIPTION In order to overcome the problems described above, preferred embodiments of the present invention provide an improved melody sound generating apparatus that is constructed with a simple circuit configuration and effectively reproduces a recorded melody sound including a plurality of sets of musical notes based on different musical scales.
Further, the preferred embodiments of the present invention provide a melody sound generating apparatus that allows the user to easily record a desired melody sample for the call-reception sound or the call-hold sound in a portable telephone.
According to one preferred embodiment of the present invention, a melody sound generating apparatus includes: a musical-scale generator which produces a plurality of musical scales based on a recorded melody pattern, each musical scale being a set of musical notes arranged in a predetermined order and at fixed separations; a melody sound data generator which produces an output melody sound data containing a plurality of sets of musical notes based on the plurality of musical scales supplied by the musical-scale generator, by adding the plurality of musical scales together; and a sound generating mechanism which plays a melody sound based on the output melody sound data supplied by the melody sound data generator.
In the melody sound generating apparatus of the preferred embodiment, the musical-scale generator produces different musical scales based on a recorded melody pattern.
The melody sound data generator produces an output melody sound data containing a plurality of sets of musical notes based on the different musical scales.
The musical-scale generator and the melody sound data generator in the preferred embodiment can be produced with a simple circuit configuration.
The melody sound generating apparatus of the present invention is effective in reproducing a recorded melody sound containing a plurality of sets of musical notes based on different musical scales.
Further, in the melody sound generating apparatus of the preferred embodiment, an input device is provided to input a melody pattern specified by a user, the input melody pattern containing a main tune and associated chords for a desired melody sample
