Stores programs and data required for reproduction processing and the like. Recorded MIDI data and the like are stored in the RAM 12.

The MIDI interface circuit 13 is an interface circuit for a MIDI input signal from the MIDI keyboard 2 or the like, or a MIDI output signal to be output to the musical tone generating device 3. The sounding body 14 is, for example, an electronic buzzer using a piezoelectric element, or a musical tone generating means combining a D / A converter, an amplifier, and a speaker, and is capable of generating a plurality of pitches under the control of at least the CPU 10. Is.

The panel 15 is composed of various switches for recording, editing, and reproducing, and a display device such as an LCD or LED. The panel interface circuit 16 includes the CPU 10
Controls to read the status of various switches and output various information to the display.

FDD (floppy disk drive) 1
Reference numeral 7 is provided as necessary and is used for storing and reading MIDI data. 18 is a bus.

With the system having such a configuration, MI
The MIDI signal input from the DI keyboard is RAM1
2 is stored in the floppy disk, edited from the panel 15, and output to the tone generator 3 (playback).
Etc. are processed.

Next, the operation will be described. FIG. 2 is a flow chart showing an outline of the recording operation of the MIDI sequencer of the above embodiment. When the recording mode is entered, first in step S1, in the designated area of the RAM 12,
It is checked whether the recorded data is already stored,
If the data is already stored, step S
Move to 2.

In step S2, the type of abnormality, for example, A is set in a specific address of the memory, and the processing is moved to the abnormality processing program. If there is no data in the memory in step S1, the process proceeds to step S3, and the control area for the recording mode on the memory is initialized.

In step S4, it is checked whether or not a MIDI signal is input from an external device, such as a MIDI keyboard, and if there is no input, step S5.
Move to. In step S5, M
Whether or not the IDI data has been input is checked using, for example, a timer by software.

If the time is within the fixed time in step S5, the process returns to step S4 to wait for the input, but if the fixed time has passed, the process proceeds to step S6 to determine the type of abnormality.
For example, B is set and the process is transferred to the abnormality processing program.

If there is input data in step S4, the process proceeds to step S7, and it is checked whether or not a free area still exists in the RAM 12, and if there is no free area, it is determined as an abnormal type. , C is set, and the process is transferred to the abnormality processing program.

If there is a free area in the memory, the process proceeds to step S9, and the input data is RA together with the internal clock data.
Write to M12. In step S10, it is checked whether or not the recording mode has ended, for example, by checking whether or not a switch for ending the recording mode has been operated. If not completed, the process returns to step S4, and Waits for the input data of.

As described above, various abnormal states occur in the processing in the recording mode, for example, and the processing program notifies the abnormality processing program of the type of abnormality.

FIG. 3 is a flow chart showing an outline of the processing of the abnormality processing program. First, in step S20, whether or not the type of abnormality is A is checked by reading a specific address in the memory, for example. If the abnormality is A, the process proceeds to step S21, and, for example, a melody a is selected from various melody data stored in the ROM 11, the data is read out, the sounding body 14 is controlled, and the melody is reproduced. Make it sound.

If the type of abnormality is not A, the process proceeds to step S22 to check whether the abnormality is B or not.
Similarly, if the abnormality is B, the melody b is generated, and if the abnormality is C, the melody c is generated. If the type of abnormality does not correspond to any,
The melody d is generated in step S26.

After the melody corresponding to the type of abnormality is generated as described above, in step S27, abnormality processing similar to the conventional one is performed. Panel 15 shows the types of abnormalities.
The process of displaying on the display of is also included.

By such processing, the user can hear different melody for each type of abnormality, and can quickly recognize the type of abnormality.

Although one embodiment has been described above, the following modifications are also possible. As the sounding body, an internal buzzer or a speaker can be used, but an external tone generating device can also be used. In this case, the MIDI data corresponding to the internally generated melody is RO
It is stored in M and the data is output via the MIDI interface circuit 13. Regarding internal and external sound control, a method that controls both at the same time and sounds from both, a method that selects only one of internal and external with a switch, a method that provides an on / off switch only outside, etc. Can be considered. In this way, the warning sound can be made more musically rich.

Further, the melody corresponding to each abnormality is RO
It is also possible to arbitrarily input and set in the M11 or the RAM 12.

Although the MIDI sequencer has been described as an example, the present invention is applicable to various electronic musical instruments, and the hardware is increased as long as it has a function of storing and generating musical tones. It can be implemented without.
