Abstract

PURPOSE:To improve the degree of freedom of performance and to improve creatability by constituting the backing pattern forming device in such a manner that automatic performance can be made by arbitrarily forming desired backing patterns and that the accompaniment by the arranging patterns formed on the basis of the registered backing patterns can be performed as well. CONSTITUTION:A memory means 22 stores the backing patterns. A registering means 21 registers the performed backing patterns into the memory means 22. A reading out means 23 repetitively reads out and outputs the backing patterns registered in the memory means 22. An arranging means 24 changes the rhythms of tones or a part of the backing patterns read out by the reading out means 23. A constitution arranging means 25 changes the sequence of the plural backing patterns read out by the reading out means 23. The backing patterns are formed for automatic performance in this way.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backing pattern generation device, and more particularly to a backing pattern generation device for generating registered backing patterns for automatic performance. In recent years, an increasing number of electronic musical instruments have the ability to automatically play specific note patterns. The note pattern mentioned above includes a backing pattern such as a rhythm pattern played with the left hand of a keyboard instrument.

0002

2. Description of the Related Art In a conventional backing pattern generation device for an electronic musical instrument, a plurality of backing patterns are prepared in advance, and a desired backing pattern is automatically played by operating each key on the bass side of a keyboard, for example.

0003

[Problem to be solved by the invention] Conventionally, backing patterns are prepared in advance, and the performer simply selects a backing pattern according to his or her performance, and that backing pattern is faithfully reproduced. There was a problem that it was not possible to change it appropriately.

[0004] The present invention has been made in view of the above points.
To provide a backing pattern generation device that can arbitrarily create a desired backing pattern and automatically perform the performance, improving the degree of freedom and creativity of the performance.

[0005]

[Means for Solving the Problems] The backing pattern generation device of the present invention includes a memory means for storing a backing pattern, a registration means for registering a played backing pattern in the memory means, and a backing pattern registered in the memory means. and a reading means for repeatedly reading and outputting the backing pattern, and an arranging means for changing the rhythm or part of the sound of the backing pattern read by the reading means, or
The apparatus includes a configuration arranging means for changing the order of the plurality of backing patterns read out by the reading means, and generates backing patterns for automatic performance.

[0006]

In the present invention, the played backing pattern is registered in the memory means by the registration means, and is repeatedly read out and output by the reading means, so that backing patterns can be arbitrarily created and automatically played in real time.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a block diagram of an embodiment of the apparatus of the present invention. In the figure, 10 is an electronic musical instrument with a keyboard such as a synthesizer, and this electronic musical instrument 10 has a performance mode selection button, and the 12 keys on the bass side of the keyboard are used for registering backing patterns. There is.

The backing pattern registration unit 21 in the backing pattern generation device 20 registers the backing pattern played using the 12 keys for backing pattern registration in the memory 22 as it is, and for example, when the lowest note key is pressed. to stop this registration. By repeating the above-described backing pattern registration operation, a plurality of backing patterns can be sequentially registered in the memory 22.

The performance form selection section 23 reads out a backing pattern from the memory 22 in the performance form selected by the performance form selection button. In this case, in the case of a normal performance or an arranged performance, the most recently registered backing pattern is repeatedly read out, and in the case of a structured arranged performance, all registered backing patterns are repeatedly read out in the order of registration.

The backing pattern read from the memory 22 is supplied to the performance form selection section 23, which directly supplies this backing pattern to the electronic musical instrument 10 in the case of normal performance, and directly supplies the backing pattern to the electronic musical instrument 10 in the case of arranged performance. Pattern backing pattern arrangement section 24
In the case of a composition arrangement performance, the backing pattern is supplied to the backing pattern composition arrangement section 25.

The backing pattern arrangement section 24 arranges the backing pattern by changing the rhythm or part of the sound using pre-registered arrangement rules or arrangement functions, and uses the arranged backing pattern as an electronic musical instrument. Supply to 10. The backing pattern configuration arranging section 25 outputs a plurality of backing patterns in the order of reading or shuffles and outputs the plurality of backing patterns according to an instruction from the performance format selection section 23 in response to the selection of the performance format selection button. The shuffle is performed using random numbers or a shuffle function, and a plurality of backing patterns output from this are supplied to the electronic musical instrument 10.

The electronic musical instrument 10 generates an audio signal by adding a backing pattern from the backing pattern generating device 20 and a melody played on a keyboard, and this audio signal is sent to a sound generation unit consisting of a mixer, an amplifier, a speaker, etc. 30
is supplied and pronounced. FIG. 2 shows a flowchart of the processing performed by the apparatus of the present invention. This process is started when the performance form selection button is operated.

In the figure, in step 40, it is determined whether or not a key for registering a backing pattern has been pressed, and only when this is pressed, the backing pattern is played in step 41 until the lowest note key is pressed. Registration is performed in the memory 22. In step 42, the selected performance form is determined. In the case of normal performance, the backing pattern read from the memory 22 is output (step 43).

In the case of an arranged performance, the backing pattern read from the memory 22 is arranged by the backing pattern arrangement section 24 and output (step 44). In the case of a composition arrangement performance, the plurality of backing patterns read from the memory 22 are output as they are or after being shuffled by the backing pattern composition arrangement section 25 (step 45).

After each of steps 43 to 45 is executed, the process returns to step 40 and the above process is repeated. in this way,
The played backing pattern is registered in the memory 22 by the backing pattern registration section 21, and is repeatedly read out and outputted by the performance form selection section 23, so that backing patterns can be arbitrarily created and played automatically in real time, and the backing patterns that have been played can be automatically played in real time. It is also possible to perform a performance using a pattern arranged based on a backing pattern, which improves the degree of freedom and creativity of the performance.

[0016]

As described above, according to the backing pattern generation device of the present invention, a desired backing pattern can be arbitrarily created and played automatically, improving the degree of freedom and creativity of playing, and is extremely useful in practice. .
