Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic musical instrument having a function of generating a tempo, such as an automatic accompaniment device or a metronome device.

Conventional technology In recent years, electronic musical instruments have built-in automatic accompaniment devices that allow for rich performance expression. Some have a one-touch play function that allows you to set the entire instrument, such as effective tone, volume, and effects. A conventional electronic musical instrument having a one-touch play function will be described below.

FIG. 2 is a block diagram of a conventional electronic musical instrument.

In Figure 2, 1 is the tone to be set on the instrument body;
A storage device that stores state data such as volume, and this data is determined for each accompaniment pattern, which will be described later.

2 is an automatic accompaniment device having a plurality of accompaniment patterns.

Reference numeral 3 denotes the main body of the musical instrument in which state data such as timbre is set. 4 is a control circuit, and this control circuit 4 reads state data such as timbre stored in the storage device 2 based on the accompaniment pattern input from the automatic accompaniment device 2, and sets the state in the instrument body 3. conduct. Reference numeral 5 denotes a switch provided outside the main body 3 of the musical instrument for the player to instruct activation of the control circuit 4.

The operation of the conventional electronic musical instrument configured as described above will be explained below.

When the player presses the switch 6, the control circuit 4 first reads the accompaniment pattern at that time through the automatic accompaniment device 2. Next, the control circuit 4 reads data on the state of the corresponding timbre, volume, etc. from the storage device 1, outputs this data to the instrument body 3, and sets the state of the timbre, etc. that is most suitable for the accompaniment pattern. .

Problems to be Solved by the Invention However, in the conventional configuration described above, when the performer presses the switch 6, the control circuit 4 operates to set the tone and other conditions most suitable for the accompaniment pattern. It only happens once, at the moment when the switch 5 is pressed, and the performer can change the state settings of the instrument body 3 one after another while playing according to the progress of the automatic accompaniment, and it is difficult to make a variety of tones and other changes during the song. This method has the disadvantage that it requires special operating techniques.

The present invention solves the above-mentioned conventional problems, and allows settings such as tones suitable for an accompaniment pattern to be automatically performed according to the progress of automatic accompaniment without the performer performing any operations during performance. The purpose is to provide electronic musical instruments with functions.

Means for Solving the Problems In order to solve the above conventional problems, the electronic musical instrument of the present invention has the following features:
a storage means for storing a plurality of states such as timbre and volume set in the main body of the musical instrument; an automatic accompaniment means for generating a constant tempo and repeatedly outputting a plurality of accompaniment patterns in synchronization with the tempo; control means for inputting data of the state determined for each accompaniment pattern and setting the state in the main body of the musical instrument, the control means operating at a cycle determined for each accompaniment pattern to set the state read the data in synchronization with the tempo,
The present invention is characterized in that a different state is set for the musical instrument body for each accompaniment pattern.

Function: The electronic musical instrument of the present invention has a control means that reads state data such as timbre in synchronization with the tempo of the automatic accompaniment means and sets the state on the instrument body, so that the musical piece can be played according to the progress of the automatic accompaniment. It is now possible to automatically set the tone and other conditions according to the accompaniment pattern one after another in synchronization with the measures and beats, without the performer having to perform any unnecessary operations during the performance. It is possible to play an instrument whose tone and other conditions are set one after another to suit the user's needs.

Embodiment Hereinafter, an electronic musical instrument according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an electronic musical instrument according to an embodiment of the present invention, and FIG. 3 is a timing chart showing state settings. In FIG. 1, reference numeral 11 denotes a storage means for storing a plurality of state data such as timbre, volume, etc. set on the main body of the musical instrument. 12 is automatic accompaniment means that generates a constant tempo and continues to output a plurality of accompaniment patterns in synchronization with the tempo.

Reference numeral 13 denotes the main body of the musical instrument, on which conditions such as timbre are set.

14 is a control means, and this control means 14 reads out state data from the storage means 11 based on the accompaniment pattern and tempo output from the automatic accompaniment means 12, and controls the instrument body 13.
to set the tone and other conditions.

The operation of the electronic musical instrument according to the embodiment of the present invention configured as described above will be described below.

The automatic accompaniment means 12 provides the control means 14 with an accompaniment pattern selected in advance by the performer, and generates a constant tempo in the control means 14. The control means 14 counts according to the accompaniment pattern based on the tempo generated by the automatic accompaniment means 12, and as shown in FIG. For each accompaniment pattern, data on the state of the tone, etc. determined for each accompaniment pattern is read out one after another from the storage means 11, and the instrument body 1
3. Set the status.

As described above, according to the present embodiment, the control means 14 is provided which automatically sets the tone color and other conditions one after another in synchronization with bars and beats in the middle of the song as the automatic accompaniment progresses.
The performer can create a tone that is suitable for the accompaniment pattern without having to perform any unnecessary operations during performance.

Performances can be performed with different levels of volume, effects, etc.

Furthermore, if a means is added for the performer to arbitrarily set state data for each accompaniment pattern, the performer can freely set conditions such as timbre and volume to perform a wide range of performances.

Effects of the Invention As described above, in the electronic musical instrument of the present invention, the automatic accompaniment means repeatedly outputs data in a predetermined state in an accompaniment pattern in synchronization with a constant tempo, and the control means outputs data in a predetermined state at a period determined for each accompaniment pattern. Since the accompaniment pattern is read from the storage means and set to a different state on the instrument body for each accompaniment pattern, there is no need for the performer to perform unnecessary operations during performance, such as setting the state of the instrument body while playing. Instead, the performer can automatically synchronize with bars, beats, etc. and perform with a tone color that matches the accompaniment pattern.
