[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rhythm performance recording apparatus capable of recording a rhythm performance state of percussion instrument sounds input by a performer.

[0002]

2. Description of the Related Art Conventionally, in a device of this type, as shown in Japanese Patent Publication No. 63-37395, for example, a reference tone generated at a predetermined timing is auditorily sensed and synchronized with this. When the performer sequentially operates the manipulator corresponding to the type of percussion instrument while visually detecting the blinking of the light emitting diode, the data representing the operation is sequentially written in the storage device over time. During the automatic rhythm performance, the written data is sequentially read out and the percussion instrument sound source is driven to perform the automatic rhythm performance in which the rhythm performance state is determined by the data.

[0003]

However, in the above-mentioned conventional apparatus, when the data for determining the performance state of the automatic rhythm is written, that is, when the operator corresponding to the type of percussion instrument is operated, the operator is operated. It was inconvenient because I could not confirm the rhythm playing state decided by.

The present invention has been made to solve the above problem, and its purpose is to easily and easily set the rhythm playing state determined by the operation when the player writes data in the storage device based on the operation of the operator. Another object of the present invention is to provide a rhythm performance recording device that can be accurately confirmed and is convenient for the performer.

[0005]

In order to achieve the above object, a structural feature of the present invention is that a plurality of operators corresponding to a plurality of percussion instrument types and operations of the plurality of operators are respectively detected. Detecting means, a storage device capable of storing data representing the operation of a plurality of operating elements, writing means for sequentially writing data representing the operation of each operating element detected by the detecting means in the storage device over time, and detecting means It is provided with percussion instrument sound source means for inputting data representing the operation of each operator detected by the above and generating a percussion instrument sound signal corresponding to the operation of the operator.

[0006]

In the present invention configured as described above, when the performer operates any one of a plurality of operators corresponding to a plurality of percussion instrument types, the detecting means detects the operation of each operated operator. Then, the rhythm performance state is recorded by the writing means sequentially writing the data representing the operation of the operated operator in the storage device as time passes. At the same time, the percussion instrument sound source means inputs data representing the operation of the operated operator, and generates a percussion sound signal corresponding to the operator.

[0007]

As described above, according to the present invention, when the data is written in the storage device based on the operation of the operator, the percussion instrument sound associated with the writing is generated. Therefore, the same playing state can be confirmed very easily and accurately, and the player's convenience can be improved.
