Musical sound generator, portable terminal, musical sound generating method, and storage medium

A mobile terminal apparatus comprising:

• a musical tone-generating apparatus including software process means for converting music contents data to hardware tone generator control data which can be reproduced, said conversion processing device being realized by software, and hardware tone generator means for generating a musical tone based on a parameter for generation of the musical tone which is contained in the hardware tone generator control data, whenever timing based on time management information contained in the hardware tone generator control data is reached, and
• a processing device that performs processing of mobile terminal functions,
• wherein said software process means is realized by part of functions of said processing device.

A musical tone-generating method comprising the steps of:

• converting music contents data to hardware tone generator control data which can be reproduced, by software;
• and
• generating a musical tone based on a parameter for generation of the musical tone which is contained in the hardware tone generator control data, whenever timing based on time management information contained in the hardware tone generator control data is reached.

A storage medium storing a program for causing a computer to execute a musical tone-generating method, the program comprising:

• a conversion process module that converts music contents data to hardware tone generator control data which can be reproduced;
• and
• a hardware tone generator module that generates a musical tone based on a parameter for generation of the musical tone which is contained in the hardware tone generator control data, whenever timing based on time management information contained in the hardware tone generator control data is reached.
