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.
Claims20
A MIDI synthesizing method comprising:
- searching for a new loop segment based on a length and a loop segment length of a sound source sample stored in a wave table to reduce the loop segment length;
- searching for an interval of the searched loop segment;
- and
- rearranging the wave table using the searched loop segment and the interval.

A MIDI synthesizing method comprising:
- if a loop segment length of a sound source sample in a wave table is equal to or smaller than 1/N (where N is a positive integer) of a length of the sound source sample, selecting the sound source sample as a new loop segment searching object;
- searching a basic cycle and a zero-intersection point from the sound source sample and determining a new loop segment based on the searched zero-intersection point;
- searching an interval from a basic frequency obtained by performing a frequency conversion on the determined loop segment of the sound source sample;
- and
- rearranging the wave table using the determined loop segment and the interval.
