PROBLEM TO BE SOLVED: To execute a performance based on tuning curve data close to an acoustic instrument by deciding the sound pitch frequency of each sound by the tuning curve data corresponding to timbre and a key number. SOLUTION: A timbre setting part 21 sets a timbre specified through the operation of a timbre selection switch, for example, the tone of a guitar, piano, etc., and makes it stored in a prescribed area of RAM 3. Then, a timbre selecting part 22 selects one timbre, as a reference for tuning control, from the plural simultaneously sounding timbres that are set by the timbre setting part 21 at the time of a dual performance. The timbre so selected by the timbre selecting part 22 is read out by a control part 23 and stored temporarily in the prescribed area of RAM 3. The control part 23, with sounding specified by the pressing of a key, carries out control by reading such tuning curve data from their storage 26 as correspond to the timbre set by the timbre setting part 21 and the key number of the pressed key. |
