Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the velocity of musical tone information used when the velocity value of the musical tone information stored in the musical tone information storage means is changed using an operator such as a vendor. The present invention relates to a value changing device.

[Prior Art] Conventionally, provided integrally or separately from the electronic musical instrument,
There is known a device called a sequencer which is used when performing musical sound editing such as composition and arrangement.

When editing a musical sound using this sequencer, first, the pitch (key number), sounding timing (key operation timing), sounding time (key depression) are operated by operating the controls on the operation panel or the keys on the keyboard. From the time until the key is released), velocity information (key pressing speed) and other musical tone information is input, and the musical tone information is stored in the memory. Then, the user reproduces the musical tone information stored in the memory and listens to the reproduced sound, or after finishing the reproduction, edits the data by operating the operator or the key to change the contents of each of the above information. , Get the desired song.

Of the above information, the velocity information is, for example, 0 to 127.
The numeric value information in the range is used. To change this numeric value information (velocity value), you can change the value by operating the keys on the keyboard, or you can change the value by operating a control wheel called the modulation wheel. , There is a method of changing the value by the operation of an operator called a vendor. The bender is an operator whose spring is biased so that the operation part provided on the wheel is always in the neutral position.By moving the operation part up and down around the neutral position, the amount of operation can be adjusted. It is designed so that you can enter the appropriate value.

When changing the velocity value using these keys or controls, the musical tone information stored in the memory is played back as described above, and when the musical tone information of the portion desired to be changed is played back. The desired velocity value is input by operating the above keys or controls. By this, the velocity value of the part is rewritten to the inputted velocity value.

[Problems to be Solved by the Invention]

However, according to the conventional method of changing the velocity value of the musical tone information described above, it is necessary to input the velocity value in real time by operating the key or the operating element, but it is possible to adjust the operation timing of the key, the operating element, the operation amount, or the like. It is difficult, and if the operation timing or the operation amount is incorrect,
The velocity value of the musical tone information in the memory is rewritten by a value not intended by the operator, and it is not easy to restore the velocity value of the rewritten portion to the original value. For this reason, the velocity value of the musical tone information, which was hard to input manually and made an effort to add a facial expression (feature) by editing the data, was rewritten to a value different from the intended value. In order to avoid the above, changing the velocity value by each of the above-mentioned methods is not usually performed so much unless it is a particularly skilled person.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to safely and easily input a velocity value in real time using an operator such as a vendor, and to reliably obtain a desired velocity value only for a portion desired to be changed. An object of the present invention is to provide a velocity value changing device for musical tone information that can be changed into a value.

[Means for solving the problem]

To achieve the above object, the present invention provides a musical tone information velocity value changing device for changing the velocity value of musical tone information including velocity values stored in a musical tone information storage means, wherein the musical tone information is sequentially reproduced. Velocity value input means for inputting a new velocity value of the musical sound information reproduced at that time when a predetermined operator is operated in the state of being operated, and the above velocity value input A velocity value storage means for storing the new velocity value input by the means in association with the musical tone information; a designating means for designating a portion of the musical tone information in which the velocity value should be changed; The velocity value of the tone information of the portion designated by the designating means is updated with the corresponding velocity value stored in the velocity value storing means. It is provided with a and city value updating means.

Further, the velocity value input means is configured to add a value corresponding to the operation amount of the operator to the velocity value of the musical sound information reproduced when the operator operates the operator to obtain the new velocity value. Is also good.

[Action]

According to the present invention, while reproducing the musical tone information stored in the musical tone information storage means, after inputting a new velocity value by operating a controller such as a vendor in real time,
Only after the rewriting portion in the musical tone information is designated by the designating means, the velocity value of the corresponding portion is updated by the inputted velocity value. Therefore, when a new velocity value is input, even if the user mistakenly inputs the velocity value, the operation amount, etc. of the operating element, and the user inputs an unintended velocity value, the designating means finally instructs the rewriting of that portion. Otherwise, the velocity value of that part is not updated, and the original velocity value is saved as it is.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram for explaining a configuration of a sequencer in which the present invention is implemented and a tone generation section connected to the sequencer.

In the figure, the CPU 1, the program and data ROM 2, the RAM 3, the input / output unit (I / O) 4, the operation panel unit 5 and the tone generation circuit 9 which constitutes a part of the tone generation unit, which constitute the sequencer, are each data. It is configured to be connected to a bus line 20 such as a bus or an address bus so that they can communicate with each other.

The CPU 1 responds to the operation of each operator of the operation panel unit 5 by
Various processes such as velocity value input process and velocity value change process, which will be described later, are executed according to the program stored in the ROM2.

The ROM 2 stores various data such as display data for the display unit 6 as well as the work program of the CPU 1.

The RAM3 is composed of a battery-backed-up RAM or a non-volatile RAM, and the RAM3 stores the original musical sound data before the data rewriting operation described later or the finally selected musical sound data after the data rewriting operation. Two memory areas are provided: a tone data memory 3a to be played and a velocity value data memory 3b for storing data representing a new velocity value input by the operation of the vendor 7 of the operation panel unit 5.

The above-described original musical tone data stored in the musical tone data memory 3a includes electronic musical instruments such as an electronic piano and a synthesizer, a keyboard portion in which keys for musical tone data input are arranged, musical tone data transmitted from an external storage device, and the like. , Musical tone data created and edited by the operation of each operator of the operation panel unit 5. These musical tone data are composed of data representing pitch (key number), tone generation timing (key operation timing), tone generation time (time from key depression to key release), velocity (key depression speed), etc. There is.
The velocity data is data representing the key pressing speed as a value in the range of 0 to 127 depending on the speed.

The I / O 4 is an input / output unit to which external devices such as an electronic musical instrument, a keyboard unit, and an external storage device can be connected.

The operation panel section 5 includes various operators for creating and editing musical tones, including operators 5a for designating a data rewriting range to be described later, operators 5b for instructing data rewriting, and the like. An interface to which a signal from a child is input and a display unit 6 for displaying various kinds of information are arranged. Further, the vendor 7 as described above is also arranged on the operation panel unit 5. From this bender 7, the neutral position, which is the steady position of the operation part, is set to 0, and the value of +64 to -64 (the value of +127 to -127 is set according to the operation amount in the vertical direction (positive or negative direction) of the operation part. However, a signal indicating
This signal is converted to digital data by the A / D converter 8 and applied to the CPU 1.

The tone generation circuit 9 forms a tone signal having a corresponding frequency, waveform, amplitude and duration based on the tone data read from the tone data memory 3a of the RAM 3 by the CPU 1. This musical tone signal is converted into an analog musical tone signal by the D / A converter 10, amplified by the amplifier 11, and then reproduced by the speaker 12. It is assumed that the musical tone generating section including the musical tone generating circuit 9, the D / A converter 10, the amplifier 11 and the speaker 12 is constituted by a device separate from the sequencer in this embodiment.

Next, the operation of changing the velocity value information of the tone data stored in the tone data memory 3a of the RAM 3 using the vendor 7 will be described with reference to the flowchart of FIG.

FIG. 2 (A) is a flowchart showing the processing procedure of the velocity value input processing executed by the CPU 1.

First, when the recording mode for inputting a new velocity value is entered, the CPU 1 reads the musical tone data stored in the musical tone data memory 3a at that time from the memory 3a in order at step S1 and causes the musical tone generating circuit 9 to read the musical tone data. It is supplied and the reproduction of the musical tone data is started.

The user performs an operation for inputting a new velocity value by using the vendor 7 while listening to the reproduced sound emitted from the speaker 12 or following the progress of the music on the display unit 6. That is, the user moves the operation unit of the bender 7 in the neutral position (position 0) in the vertical direction (positive or negative direction) when the reproduction of the musical sound data of the portion requesting the change of the velocity value is started. Perform the operation to select a value in the range of +64 to -64 that should be added to the current velocity value of the playback data. The CPU 1 detects the operation of the vendor 7 in step S2, and in step S3 adds the value selected according to the operation amount of the operation part of the vendor 7 to the value of the velocity data in the musical sound data reproduced at that time, Find a new velocity value. Then, in step S4, the new velocity value input as the above addition result is stored in the velocity value data memory 3b in association with the corresponding velocity data in the musical tone data. At this time, the CPU 1 leaves the value of the velocity data as it is without rewriting the current value of the velocity data in the tone data with this new velocity value.

On the other hand, if the operation of the vendor 7 is not detected in step S2, it means that the velocity value of the reproduced data can remain the same. In this case, the velocity value of the reproduced data remains unchanged, and the process proceeds to step S5.

In step S5, the CPU 1 determines whether or not the reproduction of the musical sound data has ended (whether or not the recording mode has been released). If the reproduction is still in progress, the process returns to step S2 and the above steps S2 to S5. The process of is repeated.
When the end of reproduction is detected in step S5, this velocity value input processing is ended.

FIG. 2B is a flowchart showing a processing procedure of velocity value changing processing executed by the CPU 1.

First, when entering the play mode for changing the velocity value, the CPU 1 reproduces the musical tone in step S1 based on the musical tone data in the musical tone data memory 3a and the new velocity value data stored in the velocity value data memory 3b. To do. By listening to the reproduced sound, the user determines whether or not the sound with the velocity value newly input by the above velocity value input processing is better than the sound based on the original velocity value (current velocity data). , If the sound based on the new velocity value is better, while listening to the playback sound,
Alternatively, after listening to the reproduced sound, operate the operator 5a for specifying the rewriting range of the data on the operation panel unit 5 to specify the entire range of the musical sound data (velocity data) to be rewritten to the new velocity value, and only the good part To pick up.

In step S2, the CPU 1 detects the rewriting range designating operation of the manipulator 5a, and when it detects that the redesignating range has been designated, the process proceeds to step S3 and the rewriting instruction manipulator 5b by the user.
Waiting for the operation of, the velocity value of the data in the specified range of the tone data (velocity data) in the memory 3a is rewritten to the corresponding new velocity value stored in the memory 3b. As a result, the tone data with the updated velocity value is stored in the tone data memory 3a.

On the other hand, when it is detected in step S2 that the operation of designating the data rewriting range has not been performed, without rewriting the velocity data in the tone data of the memory 3a,
This process ends. Therefore, in this case, the velocity data in the tone data of the memory 3a is not rewritten.

In addition, the words of these processes are
The data stored in 1 is used as the final tone data to end the tone data editing operation, or the tone data is edited again.

As described above, according to the above-described embodiment, the operation panel is operated even when the vendor 7 is operated in real time to input a new velocity value while reproducing the tone data stored in the tone data memory 3a. Unless the rewriting instruction manipulator 5b is operated by designating the rewriting portion in the musical sound data by operating the manipulating element 5a of the unit 5, the velocity value of the corresponding portion in the musical sound data is updated by the inputted velocity value. There is no such thing. Therefore, the user
It is now possible to input a new velocity value in real time with peace of mind using Vendor 7 without worrying that the velocity value will be unintentionally rewritten, and the velocity data value of the desired part can be requested without error. Can be changed to the value of. For this reason, the user can operate the vendor 7 more easily than before to change the velocity value, and the user's intention is finely reflected in the musical tone information to suit the user's preference. It becomes possible to create musical tone data for generating musical tones.

Further, according to the apparatus of the above-described embodiment, the neutral position, which is the steady position of the operation unit of the bender 7, is set to “0”, and the value corresponding to the operation amount is obtained only when the operation unit is vertically moved. Is added to the velocity value of the reproduction data and a new velocity value is input (a velocity value different from the velocity value of the reproduction data is input). Therefore, a value corresponding to the absolute position of the operation unit of the vendor 7 is input, and the velocity value of the reproduction data is updated by the input value (in this case,
In the case of a device configured so that the velocity value is updated with a value according to the position even when the operation unit of the vendor 7 is in the neutral position which is the steady position), the user is playing the musical sound data. It is necessary to always operate the vendor 7, and if the operation of the vendor 7 is not appropriate, the velocity value of the part of the tone data that the user does not want to change the velocity value is rewritten with a value not intended by the user. However, according to the device of the above-described embodiment, the user can operate the vendor 7 only at the portion where the velocity value is desired to be changed, so that the velocity value input work can be simplified. Also, if the vendor 7 is not operated in the part where the value change is not desired, the operation part of the vendor 7 is kept in the neutral position and a new velocity value is input (playback data City value and input velocity values of different values) will not be performed. In addition, since the value corresponding to the operation of the vendor 7 is added to the original velocity value, the velocity value can be finely and finely adjusted.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various effective modifications can be made based on the technical idea of the present invention.

For example, in the above-described embodiment, the vendor 7 is described as an example of an operator for inputting a new velocity value, but the operator may be a modulation wheel, a keyboard key, or the like. In the above example, a new velocity value is obtained (input) by adding a value according to the operation amount of the vendor 7 to the original velocity value, but according to the operation of the operator such as the vendor 7 Thus, a new velocity value may be directly input without performing addition or the like.

Also, to specify the part where the velocity value should be changed,
It may be performed by designating a portion that is not changed (a portion that is not rewritten), and the value of the velocity data may be updated every time the portion to be changed is designated.

Further, the switching to the recording mode or the play mode may be manual or automatic, and may not be a special mode switching.

〔The invention's effect〕

According to the present invention, even when a new velocity value is input by making an operation of an operator such as a vendor in real time while reproducing the musical tone information stored in the musical tone information storage means, the musical tone information is specified by the designating means. Unless the rewritten portion in is specified, the velocity value of the corresponding portion is not updated by the input velocity value. Therefore, the user can safely and easily input the velocity value in real time by using the operator such as the vendor without worrying about the unintended rewriting of the velocity value. It becomes possible to change the velocity value to a desired value without error. For this reason, it becomes possible for the user to change the velocity value by operating the operating elements of the vendor, etc. more easily than before, and to reflect the user's intention in the musical tone information in a finely detailed manner. It is possible to create musical tone information for generating a musical tone suitable for
