Abstract: Apparatus and method for reproducing a MIDI-based music file are provided. According to the apparatus and method, a plurality of notes and note reproduction times are extracted from the MIDI file, a section where envelope values of sound source samples exponentially reduce is changed into a linear section, and the sound source samples are outputted according to the note reproduction times by reflecting the slope of the linear section.

Abstract: 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.

Abstract: An apparatus and a method for reproducing a MIDI file are provided. In the apparatus and the method, a point that limits reproduction of a MIDI file is determined and reproduction of the MIDI file is forcibly terminated at the determined reproduction limitation point when the MIDI file is reproduced. Therefore, non-continuous points are reduced and thus noises are reduced, so that the MIDI file can be reproduced in high quality.

Abstract: An apparatus and a method for reproducing a MIDI file are provided. In the apparatus and the method, notes and note reproduction times are extracted from the MIDI file and a difference between a start point and an end point in a Loop interval of relevant sound source data according to the note reproduction time is detected and stored. The above stored difference between the start point and end point of the sound source data which will be reproduced is compensated and outputted, so that sound quality distortion in the Loop interval is eliminated or reduced.
