Apparatus and method for processing MIDI

Provided are an apparatus and a method for processing MIDI in a wireless terminal capable of controlling a volume of sound source samples when the MIDI is played. According to the method, a plurality of notes, volume levels, volume section information, and note playback duration information are extracted from an inputted MIDI file. After a volume sample number in each section is calculated using the extracted volume level and the volume section information, a volume of the sound source samples that correspond to a note that is to be played is controlled using the volume sample numbers. Next, frequency of the sound source samples are converted to a frequency assigned to the notes and the sound source samples are outputted, reducing a system load caused by the real-time play of the MIDI.

Method of synthesizing sound

There is provided a method of synthesizing a musical instrument digital interface (MIDI) having wave table support. The wave table sample information is modified based on the newly searched loop segment, the interval of the newly searched loop segment, and the fine tune data. Therefore, the size of the wave table can be reduced.
