<p>A performance date editing system is designed to efficiently convert normal performance data to execution-related performance data with simple operations and without errors. Herein, data portions which are subjected to conversion to execution-related data are extracted from input performance data corresponding to MIDI data. In addition, it is possible to further extract specific types of data, which are related to prescribed musical parameters (or events) such as attack, release, modulation and accent-plus-duration, from the extracted data portions. Hence, the extracted data portions or the specific types of data being further extracted are subjected to conversion to the execution-related data, which are supplied to an execution-related sound source (AS). Herein, a remaining part of the input performance data excluding the extracted data portions is supplied to a normal sound source (NS). Thus, the system is capable of selectively converting specific parts of the input performance data or the specific types of data to the execution-related data. This eliminates possibilities in that unwanted data are mistakenly converted to the execution-related performance data. Incidentally, the conversion is performed in accordance with a prescribed set of conversion rules, which are selected from among plural sets of conversion rules and are editable by users. <IMAGE></p> |
