DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance apparatus for sequentially reading performance data stored in a storage medium in advance and generating a desired musical tone based on the performance data. The present invention relates to an automatic performance device with improved selection of accompaniment patterns and display of performance status.

[0002]

2. Description of the Related Art Conventionally, some automatic performance devices that automatically generate musical tones include a plurality of intro patterns, main patterns, ending patterns, etc., in order to variously change the arrangement of accompaniment in accordance with the composition of the musical composition. Some of these patterns can be freely changed by switching these patterns appropriately during performance. Some automatic performance devices have a main pattern A and a main pattern B as main patterns and an intro pattern and an ending pattern as sub patterns. Selection of each of these patterns is performed by selecting and operating a pattern selection switch provided for each pattern. Therefore, the pattern selection switch has a simple indicator such as an LED for displaying the current playing state, which pattern is currently being played and which pattern is being played next. When the performance state is displayed on such a simple display device, three display modes of turning on, blinking, and turning off the LED are selectively used. For example, when the performance is performed in the order from the intro pattern to the main A pattern, the LED corresponding to the currently played intro pattern is lit and the LED of the main A pattern to be played next is blinked. When the performance is performed in the order of the main B pattern to the ending pattern, the LED of the currently played main B pattern is lit and displayed, and the LED of the ending pattern to be played next is flashed.

[0003]

The above-mentioned automatic performance apparatus has only one type of intro pattern and one type of ending pattern. Therefore, when it is desired to perform a variety of automatic accompaniments by increasing the types of intro patterns and ending patterns, the type of patterns such as an intro A pattern and an intro B pattern, or an ending A pattern and an ending B pattern can be changed. You can increase it. However, increasing the number of pattern types requires a corresponding increase in the number of pattern selection switches and indicators. Therefore, in an automatic performance apparatus having such a simple pattern selection switch, the addition of a new pattern selection switch and an additional display not only complicates the configuration of the operation panel surface but also increases the cost. There is a problem that it also leads to up, which is not preferable. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and allows a greater number of automatic performance patterns to be selected by using fewer selection switches and indicators than the patterns to be automatically played, as well as the current performance state. It is an object of the present invention to provide an automatic performance device capable of displaying a character string.

This indicates that the performance pattern of the lit LED is to be played first, and the performance pattern of the blinking LED is to be played subsequently. In this embodiment, whether the intro performance pattern is intro A,
Whether the ending performance pattern is ending A or ending B is determined by the type (A) of the lit LED and the unlit LED.
Or B) can be recognized. That is, when both the intro LED and the main A LED are lit, the intro performance pattern is intro A. Also, the LED of the intro lights up and the L of the main A
If the ED is off (and not blinking), the performance pattern of that intro is not intro A (that is, intro B). When the LED of the main A is turned off, the LED of the main B is turned on or blinking. As described above, when the LED of the intro is lit, the performance pattern type of the intro can be recognized by the on / off state of the LED corresponding to the main pattern. In other words, if there is a main LED that is turned on at the same time as the intro LED, the intro performance pattern at that time is the same type of intro pattern as the main that the LED is turned on at the same time, and the main LED that is turned off If there is, the performance pattern of the intro at that time is the LED
Is a different type of intro pattern from the main whose light is turned off. Similarly, in the case of intro B, ending A, and ending B, the type (A or B) can be recognized according to the ON / OFF state of the main LED.

In the above embodiment, two sub-patterns, an intro pattern and an ending pattern, are used.
However, the present invention is not limited to this, and various patterns such as a fill-in pattern and an interlude pattern may be similarly applied. Also, the case of two types of sub-patterns has been described, but the same applies to more types. In the above-described embodiment,
When the switch is operated during the automatic performance, the transition of the performance pattern is performed. When the operation is performed during the performance of the intro pattern or the ending pattern, the pattern is switched to a newly designated pattern when the pattern being played ends. In the case described above, when the operation is performed during the performance of the main pattern, the operation is immediately shifted to the specified performance pattern.However, the present invention is not limited to such an operation. Depending on the timing of the transition, the transition timing may be changed as appropriate, such as transition immediately or transition from the next bar. Further, the timing of this switching may be made different depending on the type of the pattern. Further, when shifting to the main pattern by operating the main pattern switch A or B, a fill-in pattern may be inserted and then shifting to the main pattern. For example, when the main A switch is operated during the intro A performance, the fill-in A pattern ("AA" indicates that the fill-in is suitable for transition from type A to type A) is inserted immediately, The main A pattern is played from the next bar, and when the main B switch is operated during the intro A performance, the fill-in AB pattern ("AB" is a fill-in suitable for shifting from type A to type B). May be inserted, and then the main B pattern may be played from the next bar. Similarly, when the main switch is operated during the playing of the ending pattern, a transition to the main pattern may be made after the fill-in pattern is inserted. In this way, when the long intro pattern or ending pattern is cut off halfway and the transition to the main pattern is made, the transition can be made naturally. In the above-described embodiment, the case where the LED of the pattern currently being played is turned on and the LED of the next reserved pattern is blinked to indicate the play order has been described. May be displayed in another display mode, that is, by changing brightness or color. The main switch LED is used to display the type (A or B) of the intro pattern or ending pattern.
Is turned on, another display mode different from the normal lighting mode may be adopted. By doing so, the operator can clearly recognize that the LED of the main switch is lighted in an auxiliary manner to identify the type of the intro pattern or the endig pattern.
