PROBLEM TO BE SOLVED: To make a reproduction tempo accurate and to simplify a setting operation of a standard reproducing tempo by correcting the standard reproducing frequency which is set at a low precision to a highly accurate value by referring to the length of a loop section. SOLUTION: In a wave display part of a display device 18, a waveform stored in RAM 16 by sampling processing is displayed, and after a wave attack part is reproduced, it is set with the mouse of an operator element group 20 which section is made to be a loop section. After setting a starting point and an end point of the loop section, clicking a chain button with the mouse of the operator element group 20 activates CPU 10 to perform correction processing of the set value Fa to an accurate standard reproducing frequency F from [Loop-Start], [Loop-End], [Sampling-Freq] and [Fa]. Thus, a standard reproducing tempo is obtained based on the number of beats obtained as an integer and the length set for the loop section. |
