Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention enables instantaneous switching of stops and combinations thereof, automatic performance, pseudo-stops, etc. by controlling the valves that make the pipes of a pipe organ sound. He is involved in the pipe organ that makes it possible to play music.

(Prior art) A pipe organ consists of pipes that have eight predetermined colors and are arranged in a certain order, a blower for blowing air through them, a keyboard for playing the pipes, and a footboard. , the action that connects the duplicate key and the pipe is mechanical,
There are pneumatic and electric types. Which of the many pipes will sound is selected by operating the stop button, but it is almost impossible structurally to have multiple correspondences between keys and valves. The number of tubes in a pipe organ is originally largely limited to the rows of pipes the organ has.

Given these circumstances, it may be possible to instantaneously change stop combinations or perform automatic performances, for example, by adding a complicated mechanism or incorporating a large amount of electrical equipment, but it is extremely difficult to achieve this. It is assumed that it will be difficult. If we could instantly change the stop combinations or create combinations that are impossible mechanically, we would be able to make full use of the organ's array of pipes, making it far more efficient. It is possible to have a & dai or make the whole small.

(Technical Problem) The present invention has been made with attention to the above points, and its purpose is to have a vibrator that has more stops than the pipe rows (number of stops) that it originally has. The object of the present invention is to provide an electronically controlled pipe organ that can be downsized and can be stopped down compared to conventional pipe organs having the same function.

Another object of the present invention is to! To provide an electronically controlled pipe organ which can be easily played by inputting from a keyboard and by installing an external storage device.

Another object of the present invention is to provide an electronically controlled vibe organ that allows instantaneous change in stop combinations.

(Technical Means) The present invention which achieves the above-mentioned object is to provide a solenoid valve that connects to the wind conduit and listens to the ventilation passage leading from the lζ die bar to the pipe, and connects each Wi solenoid valve to the output port of the microcomputer. This is an electronically controlled pipe organ having a structure in which a stop button for specifying a stop and a keyboard for specifying a pitch are connected to the input port of the computer.

(Operation of the invention) The vibe organ of this invention uses a solenoid valve as a valve for making the pipe sound, and is controlled by a microcomputer.
This method allows you to change the correspondence between the stop button, keyboard, and solenoid valve as you like.

(Example) This will be explained in detail below using examples.

FIG. 1 is a block diagram of a vibe organ according to the present invention, and FIG. 2 is a conceptual diagram of a microcomputer group. In each figure, 1 is a keyboard, 2 is a stop knob, and 3 is an 8-bit microcomputer ( CPLI), 4 is a chamber or wind box part that receives the wind from the blower 5 through the wind pipe 6 and the damper 7, and sends it to the pipe 8. A ventilation passage 9 to the pipe 8 is provided in the chamber. The pipe 8 and chamber 4, in which the solenoid valve 10 for opening and closing is provided, may be of the same type as a conventional vibrator, but it is not necessary that the stop tunnel be independent for each pipe.

The microcomputer is an 8-bit microcomputer 11 (for example, 280) as the CPU, and an 8255A as the LSI for the 110 interface 12.
is used.

Next, the operation of this pile organ will be explained. Normally, the organ stops are Pr1ncipal 8', llo
lzgedackt 4', Rohrrlate 4
', Crua+horn2', etc., are named according to the shape, length, and sounding mechanism of the tube. Various configurations of pipe rows (stops) can be considered, but here we will use Gedackt 8', Pr1ncipa for ease of understanding.
An example of a pipe organ having two rows of pipes 4' and 61 keys will be explained.

First of all, when this system functions as a normal pipe organ, all 61 keys are valid because of Gcdack.
This is when t 8' or Pr1ncipal 4' is selected. When a stop button is pressed and a certain stop is selected, a signal from the stop button is transmitted to the CPU.

In response to this signal, the CPU executes a preprocessing routine (here, Gedackt8' or Pr1ncip).
al 4 ′) is determined.

Keyboard information is sent to the CPU at any time, and the sent signals are processed according to a routine determined by the stop button. This 70-diat is shown in FIG.

In this case, Gedackt 8' or Pr1nci
pal 4' (hereinafter abbreviated as G8' or P4', etc.), so for example, when you press the C1 key, G
This routine provides an output that opens the C1 valve of P4' or P4'. Therefore, if you press the 01 key, 08'
Or C1 of P4' sounds.

Next, we will explain the case where the top octave is invalid (8 does not sound even when pressed), that is, the 49th key is valid. However, in this case as well, if a pipe is provided roughly one occlave above, all [13] are valid. The number of stops is G8', P
G4' and r'2' are added to 4' for a total of four.

As above, by pressing the G4' and P2' buttons, a signal is sent from the stop button to the CPU.

The CPU processes the signal using a pre-made program, and opens the valve corresponding to G4' or P2' (that is, 08', a valve one octave higher than P4') when the key is pressed. In this way, if up to 37 keys are valid, G2'
, P1', if valid up to 25w1, G1', P
1/2' stop can be selected. Furthermore, in this way, you can select H+XturO,
It is also possible to switch between modern bids.

Modern large organs also have a combination button that allows you to specify a registration in advance and instantly switch stop selections. Next, this embodiment will be explained.

The present invention can be configured to enable instantaneous stop selection switching even in a small positive A gun by electronic control. The method is to record the stop combinations used during the performance on the stop buttons, and then
~Press the stop button corresponding to the rib whose knob needs to be changed. Using this method, the stop combination can be changed with one touch. For example, play the first half with G8' and P4', change to P4' and P2' in the middle, and finally play G8'.
, G4'P4' , If you want to play a song with P2', I
G8' to IQl, P4' to 11112, P
2', N (G8', P4', G4', P
Insert 2' and J3 <. As the song progresses, IIQ1~
All you have to do is press the stop buttons in order.

Next, an example of automatic performance will be described.

The basic signal flow of this system is from the keyboard to the computer to the valve, but automatic performance is possible by directly controlling the opening and opening of the valve from the computer.

For example 1. If you want to play the do-re-mi-faso tone of a quarter note in C key with I=120, use P4'c',P4'd',P4'e', P4L for 0.5 seconds each.
If you create a program that opens the fl, p, ll, and ql valves in sequence, and run this program, you can automatically make the above note type sound. In addition, you can push a very difficult passage onto a certain key/υ, or press a difficult part of the fingering to I! You can make it easier by changing the correspondence between the panel and the valve. The method of inputting data is to input it directly from tait. Furthermore, long-term automatic performance is also possible using an external storage device such as a disk or an IC card.

(Effect of the invention) Since the present invention is configured as shown in 1- below,
It has a great effect.

(1) It is possible to downsize and reduce costs because the number of stops above 1.5 mm increases.

(2) Stop combinations can be changed instantaneously during performance (81 functions of the combination button).

(3) Automatic performance can be performed using a pipe organ.

(4) In terms of usage, it is most suitable for playing general pipe organ music, and can be used in any situation where a positive organ is used.

(5) Due to its miniaturization, it can be used as a pipe organ for more comprehensive practice at home and for ensembles.
