Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data editing device for editing various data such as tone color data.

[0002]

2. Description of the Related Art Conventionally, when creating a new timbre,
A timbre data editing device is used. Original tone color data is stored in this tone color data editing device, and a new tone color is created by an editing operation for changing the values of parameters such as envelopes and filters of this tone color data. Then, in the tone color data editing device having a so-called compare / recall function, when a new tone color is being created and it is desired to compare it with the original tone or when the tone is restored to the original tone,
Operate the recall switch. Then, the original tone color data before changing the settings of the envelope, the filter, etc. is read out, and the original tone can be heard by driving the sound source with this tone color data. If the new tone color being created does not have the desired characteristics, a new tone color is created again by setting the envelope and filter of the read original tone color data to values different from the previous values.

[0003]

However, in such a conventional compare / recall function, when this function is expressed by a switch operation, all the parameter values of the new tone color data being created are the original tone colors. It will be returned to the value of the data parameter. Therefore,
It is not possible to create a tone color while changing the parameter value while listening to the tone color before changing the value of a certain parameter and the tone color after changing the value. In addition, since all the set parameter values are returned to the original tone color data, if you change the value of a certain parameter and the desired tone color is not desired, you cannot continue the creation from the state before the change. . Therefore, the parameter values have to be set again from the original tone color data, and the desired tone color data cannot be efficiently edited.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a data editing apparatus capable of efficiently editing desired data based on original data. It is a thing.

[0005]

In order to solve the above problems, according to the present invention, original data storage means for storing original data, input means for inputting parameters and their values, and the input means Edit means for sequentially editing the original data based on the parameter and its value for each input; edit data storage means for storing the data edited by the edit means; and, in the first mode, the edit data storage means. And a data output means for outputting the data stored in the edit data storage means, and an edit control means for starting the editing by the edit means from the data stored in the edit data storage means in the second mode.

[0006]

In the above structure, when a parameter and its value are input, the original data stored in the original data is sequentially edited by the editing means for each input. At this time, the sequentially edited data is stored in the edit data storage means. In the first mode, since the data output means outputs the previously stored edited data, the data output from this data output means is compared with the data currently edited by the editing means. Is possible. In the second mode, the edit control means does not start editing from the original data, but starts editing from the already edited data stored in the edit data storage means.
