Abstract

PURPOSE:To generate an accompaniment pattern corresponding to choice, and to output an accompaniment sound signal by selecting arbitrarily accompaniment pattern data set and generated in advance by selecting and combining arbitrarily data of each part for constituting the accompaniment pattern from in plural accompaniment pattern data. CONSTITUTION:When a performer turns on a power source of a main body, an initial processing is executed. As for a tempo processing, when it is decided that a tempo-up SW is depressed, a value of a tempo data register TR is increased, and a tempo is raised. As for a rhythm switching processing, when it is decided that a rhythm selection SW is switched, the corresponding rhythm number is written in a rhythm number register, and a display processing is executed. When the display processing is executed, a rhythm switching processing is finished. Subsequently, after passing through auto operation mode processing, an acamp mix mode processing, a tone color switching processing, a rhythm reproduction processing, and various switching processings, the processing returns to a main operation. In such a way, by repeating the loop processing, a rhythm sound is sounded in accordance with the rhythm number corresponding to a value shown by the rhythm number register.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an automatic accompaniment device, and more particularly, the present invention relates to an automatic accompaniment device, and in particular, it is possible to arbitrarily select and combine data of each part constituting an accompaniment pattern from among a plurality of accompaniment pattern data that are created and stored in advance. It is possible to create an accompaniment pattern according to the mode, and output an accompaniment sound signal by arbitrarily selecting accompaniment pattern data created by switching the mode and accompaniment pattern data created by setting in advance. Regarding an automatic accompaniment device that can be used. [Prior art] Generally, an accompaniment pattern consists of three patterns: rhythm, bass, and chords.
It is composed of two parts. Originally, it would be best to create this accompaniment pattern each time according to the image of the song, but since it is quite specialized, there are two conventional methods for processing accompaniment pattern data in automatic accompaniment devices. There was. One is an automatic accompaniment device that allows users to create three new parts: rhythm, bass, and chord, and establish it as an automatic accompaniment pattern. The other is an automatic accompaniment device in which several types of accompaniment patterns created in advance are stored in advance as data, and the performer can freely select from among the stored accompaniment pattern data.

[Problem to be solved by the invention]

However, among conventional automatic accompaniment devices, the former is too specialized for users to create the three parts of rhythm, bass, and chords by themselves, and is not suitable for general users. The problem is that it is not possible to have Furthermore, among conventional automatic accompaniment devices, the latter is designed to be preset, so the user cannot change the automatic accompaniment pattern at all, and can freely use automatic accompaniment patterns other than those prepared in advance. The problem is that it cannot be configured. The present invention creates an accompaniment pattern according to one's preference by arbitrarily selecting and combining the data of each part constituting an accompaniment pattern from among a plurality of accompaniment pattern data that are created and stored in advance. To provide an automatic accompaniment device capable of outputting accompaniment sound signals by arbitrarily selecting accompaniment pattern data created by switching modes and accompaniment pattern data created in advance. It is an object. [Means for Solving the Problems 1] In order to achieve the above object, the automatic accompaniment device of the present invention is composed of a plurality of parts and stores a plurality of types of accompaniment pattern data in which each part is set in advance. The first
accompaniment pattern storage means, selection means capable of arbitrarily selecting a plurality of types of accompaniment pattern data stored in the first accompaniment pattern storage means, and each part of at least one accompaniment pattern data capable of being stored. The second
accompaniment pattern storage means, and the accompaniment data stored in the first accompaniment pattern storage means selected by the selection means of each part of the accompaniment pattern data stored in the second accompaniment pattern storage means. an accompaniment pattern creating means for creating a new accompaniment pattern by replacing data of each part corresponding to the pattern; a mode switching means capable of arbitrarily switching between a first mode and a second mode; and the mode switching means. When the means selects the first mode, the accompaniment pattern is based on the accompaniment pattern data selected from the first accompaniment pattern storage means by the selection means, and when the means selects the second mode, the accompaniment pattern is stored in the second accompaniment pattern storage means. and accompaniment sound signal output means for outputting an accompaniment sound signal based on the data. [Effect 1 The accompaniment of a song is composed of four elements: intro, main pattern, fill-in, and ending. Accompaniment pattern data for each of the intro, main pattern, fill-in, and ending are stored in multiple types of accompaniment patterns for clause 1. stored in the means. A plurality of accompaniment pattern data stored in the first accompaniment pattern storage means is arbitrarily selected, data of each part is read out, and a new accompaniment pattern (second accompaniment pattern) is created. The created second accompaniment pattern is stored in a second accompaniment pattern storage means having a temporary storage function. and,
The first mode of the accompaniment pattern data stored in the first accompaniment pattern storage means and the second mode of the accompaniment pattern data stored in the second accompaniment pattern storage means are arbitrarily switched by the mode switching means. Based on the selected accompaniment pattern data, an accompaniment tone signal is outputted by the accompaniment tone signal output means and emitted. Therefore, according to the present invention, by arbitrarily selecting and combining the data of each part constituting an accompaniment pattern from among a plurality of accompaniment pattern data that are created and stored in advance, an accompaniment pattern according to one's preference can be created. Automatic accompaniment can be performed by outputting an accompaniment sound signal based on either accompaniment pattern data created by switching the mode or accompaniment pattern data created by setting in advance. It can be performed. [Example] Hereinafter, an example of the automatic accompaniment device according to the present invention will be described.

Effects of the Invention 1 Since the present invention is configured as described above, it produces the effects described below. A new accompaniment pattern is created by arbitrarily selecting and combining the data of each part constituting an accompaniment pattern from among multiple types of accompaniment pattern data in which each part is set and stored in advance. A different type of accompaniment pattern is created and the created accompaniment pattern data is temporarily stored. In addition, you can freely change the accompaniment pattern by arbitrarily switching the mode between the first mode, which uses accompaniment patterns that have been set and stored in advance, and the second mode, which uses accompaniment patterns that have been created and temporarily stored. You can choose. Since it is possible to create a new accompaniment pattern by replacing the data of each part of the accompaniment pattern data generated in the first mode with the data of each corresponding part of the accompaniment pattern of the second mode, it is possible to create a new accompaniment pattern. It is possible to quickly and easily create different accompaniment patterns for some parts of accompaniment data. In this way, the present invention can arbitrarily select and combine data for each part (rhythm part, bass part, chord part) constituting an accompaniment pattern from among a plurality of accompaniment pattern data that are created and stored in advance. This allows even people with no musical knowledge to easily and quickly create accompaniment patterns according to their preferences, and by switching modes, you can easily and quickly create accompaniment pattern data and accompaniment patterns that have been created in advance. It is possible to arbitrarily select data and output an accompaniment sound signal.
