PROBLEM TO BE SOLVED: To provide a synthesizer for acoustic signals capable of reproducing the acoustic signals of a range wider than before even while utilizing standard code data based on a prescribed standard such as an MIDI standard. SOLUTION: A general purpose standard data form (figure 3 (a)) and an extension data form (figure 3 (b)) capable of handling highly accurate data are prepared. In the extension data form, the number of channels for recording each of single sound for constituting chords is increased, a note number can be more finely recorded by providing a fine pitch and further, a lot of sound velocities can be recorded. Thus, highly accurate sounds which can not be reproduced by the conventional standard data form can be reproduced. |
