Description

[Detailed description of the invention] [Technical field of the invention] The invention relates to a rhythm playing device of an electronic musical instrument.

[Prior Art and Problems] Conventionally, as a device that can freely perform rhythm and accompaniment (hereinafter, referred to as a rhythm playing device), a plurality of different rhythm sound sources are provided for each of a plurality of basic rhythms (for example, rock and waltz). It has a rhythm pattern and also has several different accompaniment patterns for accompaniment sound sources for each basic rhythm,
For pattern selection, select the basic rhythm with the basic rhythm selection switch, select the rhythm pattern of each rhythm sound source in the selected basic rhythm with the rhythm variation selection switch for each rhythm sound source, and select the accompaniment in the basic rhythm with the accompaniment variation selection switch. What can select a pattern is known. This type of rhythm playing device is convenient because a user can select a desired pattern from a very wide variety of patterns.

Further, there is known a rhythm playing apparatus of this type which can temporarily play a different pattern (change pattern) in accordance with the progress of a music piece during automatic performance. This has been devised in view of the fact that the same pattern is repeatedly played and becomes monotonous only with normal performance, for example, a so-called fill-in performance is a performance mode played between normal performances, A change pattern called a fill-in pattern is temporarily inserted. Also, when a rhythm performance according to a performance pattern called an intro performance starts a song, it can be performed prior to a normal performance, and a rhythm performance according to a performance pattern called an ending performance is performed after the normal performance. Is performed in the case where the process is repeated throughout.

Unfortunately, in this type of rhythm playing device, the patterns (normal rhythm patterns) that can be used for normal playing are very abundant as described above, but the changing patterns are very limited. That is, in this type of conventional technology, one change pattern (for example, one fill-in pattern, one intro pattern, and one ending pattern) is provided for each basic rhythm.
Only is prepared. By selecting the basic rhythm with the basic rhythm selection switch, the change pattern to be played is also determined, and there is no freedom to select.

Further, a major problem is that since there is only one change pattern, it often becomes musically unnatural with other patterns. For example, disharmony with a normal rhythm pattern, disharmony with a change accompaniment pattern, and the like may occur.

If the number of changing rhythm patterns is about the same as the number of abundant normal rhythm patterns, musically, a changing accompaniment pattern played simultaneously with the changing rhythm pattern performance and a normal pattern automatically played before and after are provided. It is possible to select the optimum changing rhythm pattern in consideration of the above. However, this usually requires a complicated operation for only the changing rhythm pattern that occupies only a part of the performance time, and imposes a heavy burden on the user.

[Purpose of the Invention] Accordingly, the present invention provides a rhythm playing device for an electronic musical instrument that simplifies the automatic performance setting operation in the special performance mode, reduces the burden on the user, and enriches the rhythm pattern variations in the special performance mode. The purpose is to provide.

[Summary of the Invention] In the normal performance mode, the present invention allows an automatic performance based on the rhythm pattern selected for each sound source by the pattern selection switch means and the accompaniment pattern selected by the accompaniment pattern selection switch means to perform a special performance. In the mode, the main point is to have control means for automatically performing a performance based on a rhythm pattern set in advance corresponding to the accompaniment pattern selected by the accompaniment pattern selection switch means.

According to the present invention, there is a rhythm change pattern corresponding to the number of accompaniment patterns, and the accompaniment variation selection switch means has not only an accompaniment pattern selection function but also a rhythm change pattern selection function at the same time. . It is easy to determine in advance (for example, on the maker side) which rhythm change pattern matches which accompaniment pattern well. As a result, at the time of changing performance such as fill-in, harmony between the changing accompaniment pattern and the rhythm changing pattern is achieved, and a well-balanced automatic performance can be performed.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an overall configuration diagram of an electronic musical instrument incorporating an automatic performance device according to the present embodiment. The entire system is controlled by the CPU 1, and the ROM 2 stores various rhythm patterns and accompaniment patterns as information related to the present embodiment, in addition to the control program of the CPU 1. For each of the multiple basic rhythms,
A plurality of different (here, four types) normal rhythm patterns are prepared for each rhythm sound source. Also, for each basic rhythm, a plurality of different (here, four types) normal accompaniment patterns for accompaniment sound sources and four types of change accompaniment patterns for each change (for fill-in, intro, and ending) are prepared. I have. Also, as the rhythm change pattern, four types of change patterns of the same number as the accompaniment pattern are prepared for each of the basic rhythms for each of the fill-in, the intro, and the ending. The RAM 3 stores various data in a rewritable manner and is accessed by the CPU 1.

Reference numeral 4 denotes a group of various switches, a partial layout of which is shown in FIG. The illustrated one is a rhythm-related switch group, which itself has a known configuration. 41a to 41c are basic rhythm selection switches, where "lock" is set by the switch 41a and "swing" is set by the switch 41b.
“Waltz” is selected by the switch 41c. The light emitting diode LED near each switch lights to indicate which basic rhythm is selected. Reference numerals 42a to 42e denote pattern selection switches for each sound source. Each switch operates cyclically (I to IV). For example, each time the switch 42a is pressed (for the currently selected basic rhythm), the bass sound source is switched. Variation No. that defines the pattern of I, I
I, III, IV, and I are selected, and the related LEDs are sequentially lit cyclically. Reference numeral 42e denotes a variation selection switch for an accompaniment sound source. As will be described later, according to this embodiment, the switch 42e has a function of selecting a rhythm change pattern during a change performance. 43a to 43c are switches for selecting a rhythm automatic performance mode, a start / stop switch 43a is for starting and stopping a rhythm, a synchro / ending switch 43b is for switching to a synchro mode or an ending mode, and an intro / fill-in. Switch 43c
Is a switch for switching to an intro mode or a fill-in mode. Since the transition of the automatic performance mode is not directly related to the present embodiment, the description is omitted.

Returning to FIG. 1, 5 is the upper key, 6 is the lower key, 7
Is a pedal key. Reference numerals 8 to 11 denote sound sources that generate musical tones in accordance with key press information or automatic performance patterns. For convenience of explanation, 8 is a melody sound source, 9 is an accompaniment sound source, 10 is a bass sound source, and 11 is a rhythm sound source. The outputs of the sound sources 8 to 11 are converted into analog signals by the corresponding D / A converters 12A to 12D,
After passing through various effect sections 13, it is amplified by the amplifier 14,
Sound is emitted from the speaker 15.

Hereinafter, the operation will be described. First, rhythm switches
It is assumed that 41, 42, and 43 are appropriately operated, and an appropriate basic rhythm and a variation number of each sound source are set.

During normal automatic performance (for example, when the automatic performance is stopped, the mode is entered by pressing the start / stop switch 43a), as shown in FIG. Search for the variation number of BD (bass drum), SD (snare drum), HH (hi-hat), PC (percussion) selected via the variation selection switches 42a to 4d of each rhythm sound source (S
1) Read each normal rhythm pattern from ROM2 according to each variation number searched. Further, the variation number of the accompaniment selected via the accompaniment variation selection switch 42e is searched (S3), and the corresponding accompaniment pattern is read out from the ROM 2 and selected (S4). Then, sound processing is performed on the rhythm sound source 11 and the accompaniment sound source 9, and both sound sources 11, 9 are driven in accordance with the selected normal rhythm patterns and the normal accompaniment patterns (S5,
S6).

FIG. 3 illustrates the progress of the rhythm during the normal automatic performance. For example, when variation II is selected with the snare switch 42b, variation I is selected with the bass drum switch 42a, and variation II is selected with the accompaniment switch 42e, it is indicated by "snare II", "bass II", and "accompaniment II". A performance is performed.

The normal pattern in the normal automatic performance described above is the same as the conventional one in that the user can independently select the sound pattern for each sound source.

However, according to the present embodiment, the rhythm pattern during the changing performance is selected by being linked one-to-one with the selection of the accompaniment pattern.

For example, during a fill-in performance (for example, by pressing the intro / fill-in switch 43c during a normal performance, this mode is entered), the accompaniment variation No.
After searching (T1), one of the four types of fill-in rhythm patterns is selected using the variation No. (T2),
One fill-in accompaniment pattern is selected from the four types of fill-in accompaniment patterns (T3). The following is the same as the case of the normal performance, and the rhythm sound source 11 and the accompaniment sound source 9
Sound according to the selected pattern (T4, T5).

Other changes in performance, such as during intro performance or ending performance, are processed in the same way as during fill-in performance (steps U1 to U5) and (steps V1 to V5). Of course, the selection is not from among the four types of fill-in patterns, but from among the four types of intro patterns and ending patterns.

FIG. 4 illustrates a state during the fill-in performance. As described above, according to the present embodiment, the accompaniment pattern (change accompaniment pattern) during performance change and the rhythm pattern (rhythm change pattern) are in a one-to-one correspondence. For example, when “accompaniment I” is used, the “rhythm” is used. When "I" is used and "accompaniment II" is used, "rhythm II" is used. Making the corresponding accompaniment and rhythm patterns harmonious can be easily set in advance.

During musical changes, for musical reasons, etc.,
It may be excluded from rhythm and accompaniment performance targets. For example, it is often unnecessary to prepare an accompaniment pattern during an intro performance.

[Effects of the Invention] As described in detail above, the present invention is based on the rhythm pattern selected for each sound source by the pattern selection switch means and the accompaniment pattern selected by the accompaniment pattern selection switch means in the normal performance mode. Automatic performance is performed, and in the special performance mode, automatic performance is performed based on a rhythm pattern set in advance corresponding to the accompaniment pattern selected by the accompaniment pattern selection switch means. In addition, the effect of simplifying the automatic performance setting operation in the special performance mode in which the performance time is short, reducing the burden on the user, and enriching the rhythm pattern variations in the special performance mode can be obtained.
