Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic musical instrument, particularly an electronic musical instrument that can be added to an electronic musical instrument to perform a new function. I!
It not only improves efficiency, but also improves efficiency in manufacturing, market service, etc.! 1.゛Conventional configuration and its problems Electronic musical instruments to which an external storage device can be optionally connected have been commercialized, but in all cases, the memory content was created by the electronic musical instrument or was supplied by the manufacturer. It was setting data for effects, tones, etc., or performance data for G, I LFF1. In other words, the purpose of connecting a storage device to the electronic 51P5 was to simply record or reproduce data related to the performance of the electronic musical instrument.

Therefore, in an electronic musical instrument where most of its functions are controlled by the CPU, it is customary to develop a CPU operation program that includes all of the additional functions. Met. If a product has multiple additional functions, it will take a lot of time to commercialize it, or if you want to commercialize it between +AOIIIJ and AOIIIJ, you will have to give up some extra functions. It means that.

This means that the cycle of commercialization of electronic musical instruments will be shortened.
Also, the king's (;1! Noh's somewhat t"ljQ
Due to bad developments, Nanakona 9:i's plan is decided, and the exit to L or 15 (this 115 is considered a big problem).

Purpose of the Invention The present invention 1 is to supplement the conventional method,
While commercializing an electronic musical instrument in a short period of time, we developed additional functions. Purpose and 116 things.

414 Forms of the Invention The present invention is based on the external n[! Using 10 devices, we set up a configuration where f1 can be connected arbitrarily, and set it to electronic data H3, taking advantage of all or 1,72 of C's original instincts. The operating program that is used is actually 11[7 URUJ, Unishashino], and by this, it is possible to connect storage devices with different storage contents and create electronic music.

Embodiment: From 11 to 1, an embodiment of the present invention is shown with a block diagram and a diagram.
-1- Figure 1 shows an electronic musical instrument body 1 with +41 as an external storage device.
FIG. 2 is a flowchart showing the operation of this embodiment.

In FIG. 1, 3 is a CPU that controls the rest operation of the electronic musical instrument main body 1, normally drives a memory control signal 10 and an address bus 11, and then sends programs and data on the memory 4a through a data bus 12. Assume that there is one read or write operation in row 4. However, at least a part of the memory 4a is composed of a RAM.

First, after the electronic musical instrument body 1 starts operating, the electronic musical instrument main body 1
After performing J stage determination 21, if the magnetic disk device 2a is not connected, both determination 23 and determination 29 branch to NO;
The original place of electronic musical instruments Fl! Only steps 22J3 and 31 are performed, and the process is repeated thereafter. this! If the magnetic disk 1i17?2a is connected during processing 121, the state of the storage device connection confirmation terminal 14 changes, and the result of determination 231 is YE.
Branch to S. When the magnetic disk unit 12a is connected, the user performs the operation 1) to specify the magnetic disk drive.
Branch to ES, CP tJ: 1 is magnetic disk charge 11
A2, 'l control 1111 fir number 13 using address bus 11 and data bus 12, disk control unit 6
The disk drive 5 is driven to read the identification code of the disk contents recorded on the rotary disk 10.

In the tJ1 Song era, if there is a disc that records performance data, then read the performance data from the disc, and if there is an execution program recorded on the disc, then read the execution program from the disc. data bus 1 at the same time
2, the memory is stored in a predetermined location in the RAM area of the memory 4a1 (processing 2G or 27). Furthermore, the storage of the execution block [''Daram is completed 1. ``I'' sets the program transfer completed flag on the internal register (process 28) and uses it for subsequent determination.

The execution program is transferred from the Shoki T isk device 2a to the memory 4.
When the program has been sent to the predetermined area of 47i, the program transfer completed flag is set to 1, and b,
By branching to 29' (-YIES...
Execute the execution program supplied from the disk device 2a 30, return to the original program 31, and repeat this process. Therefore, by recording a new execution program on the magnetic disk-1 and supplying it to the main body of the electronic musical instrument, it is possible to operate various functions in addition to its original functions.

As in this embodiment, the operation program stored in the external storage device 2a is once loaded into a specific storage area of the electronic musical instrument body 1, and then the old operation program stored in this specific storage area is executed. In this case, there is an advantage that only the programs necessary at any given time can be executed from the external memory 1 and 2a in so-called small batches.

A second embodiment of this book 1g1 will be described using FIGS. 3 and 4. Figure 3 shows the case where a semiconductor memory device +ffl 211 is connected as an external memory device, and 1 in Figure 2.
, 3 , 10.11. +2J5 and 14 are the same as in FIG. 4b is a memory that does not include a RAM, and 7 is a semiconductor memory element.

In the case of the configuration shown in FIG. 3, if the normal semiconductor storage device Y12b is not connected, the determination 34 branches to No at 7G-t-- in the εn/1 diagram, and the processing 33jjJ of the main body of the electronic musical instrument 1 is performed. Only 37 is 4 and 3! At this time, the semiconductor memory V< 1ffi 2 b is connected, and the state of the IQ device 1 connection check changes, and the state changes to YES at determination 34. For example, if the recorded content of the semiconductor storage device 2b is performance data, the voltage is set to ``H'', and if it is an execution program, the voltage is set to ``L''''. By determining the state, the semiconductor memory device 2
If it is possible to determine the memory contents of the semiconductor memory element 7 in b and write the operating program in 1a, then branch from determination 35 and write the operating program on m element 7. Execute 36. Therefore, by adding f-1 and writing various operation programs to the semiconductor memory module 7, and connecting it to the electronic musical instrument body 1, the programs can be easily added. You can actually make it happen.

Although the embodiment has been described using a magnetic disk device and a semiconductor storage device in the storage medium, it is also possible to apply other methods such as a 141 card system, a bar code system, or an optical disk system.

Furthermore, according to the present invention, it is possible to perform various types of I4 functions in addition to the electronic musical instrument H'A.
Specific applications include 1. Inspection and adjustment programs during the equipment process of electronic musical instruments themselves, 2. Operation confirmation or Ij; i prisoner investigation programs during market service, 3. Music education programs for pitch sense, chords, etc. 4. , music games using electronic musical instruments, and the like. Normally, it would be almost impossible to develop an electronic musical instrument that includes some or all of these programs (because it would result in a long lead time between product launches and an increase in the cost of the program ROM, etc.), but this By using the invention, the application program can be additionally executed without causing the above-mentioned inconveniences, and the contents can be easily changed, making it flexible.
[You can take action.]

Effects of the Invention In the present invention, an electronic musical instrument is connected to an external memory, and an operation program stored in the external memory device can be executed as necessary. ,
°It will significantly expand the scope of use of electronic musical instruments.
