Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a musical tone information processing device, and more specifically, it provides a device that can synthesize and record a musical score pattern based on a predetermined code signal corresponding to a musical tone signal.

FIG. 1 is a block diagram showing the basic configuration of the present invention, in which 10 is a code signal generator that generates predetermined code signals corresponding to musical tone signals, and 20 is a code signal generator that generates predetermined code signals corresponding to musical tone signals based on these code signals. A score pattern synthesis section 30 that synthesizes score patterns is a recording device that records these synthesized score patterns.

The code signal generator 10 generates a first code signal corresponding to the scale of the musical tone signal to be recorded (hereinafter referred to as the scale code signal) and a second code signal corresponding to the tone length (hereinafter referred to as the tone length code signal). It is something to do. As such a code signal generator 10, for example, a keyboard input device is used, and a predetermined code signal corresponding to a desired musical tone signal is generated by key operation. In the case of a keyboard instrument such as a piano, each key may be provided with a relay contact to generate a contact signal corresponding to a predetermined code signal. Additionally, if necessary, it may be configured to analyze musical tone signals input through a microphone to detect scale information and tone length information, and generate a predetermined code signal corresponding to each of these pieces of information. can.

The musical score pattern synthesizer 20 includes an input control section 21,
It is composed of a pattern signal generation section 22, a storage section 23, an arithmetic control section 24, a decoder 25, an I/O port section 26, etc., and a data bus DB,
They are connected via address bus AB, control bus CB, etc. The input control section 21 controls the signal input from the code signal generator 10 to the musical score pattern synthesizer 20. The pattern signal generator 22 stores a plurality of musical score information patterns such as notes, rests, symbols, etc. necessary for musical score creation as dot patterns. These musical score information patterns are
It is read out based on the scale code signal and tone length code signal sent from the code signal generator 10. Note that most of the musical score information patterns (notes, rests, change symbols, etc.) are stored as patterns that do not have a 5-line staff, and after being read out, these patterns are shifted by a predetermined amount and Superimposed on the line score. Thereby, the amount of information stored in the pattern signal generating section 22 can be significantly reduced. Storage part 2
3 temporarily stores the patterns read out from the pattern signal generation section 22 in block units corresponding to the number of musical tone signals set in advance, and synthesizes musical score patterns corresponding to the musical tone signals in this storage section 23. will be carried out. When the synthesis of musical score patterns corresponding to a certain block of musical tone signals is completed, the contents are sent to the recording device 30, and the process moves on to synthesis of the next block. The arithmetic control section 24 controls each section of the musical score pattern generator 20 including the pattern signal generation section 22 and the storage section 23 based on two types of code signals inputted from the code signal generator 10 via the input control section 21. It also controls the code signal generator 10 and the recording device 30, and is configured to perform various calculation controls according to a preset program. Note that the arithmetic control unit 24 has a storage unit that stores programs, constants, etc., but is not shown. The decoder 25 converts the address code, and the converted output is sent to each section. I/
The O port section 26 controls the transmission and reception of signals between the recording device 30 and the musical score pattern synthesizer 20.

The recording device 30 records the musical score pattern synthesized by the musical score pattern synthesizer 20, and uses a dot printer. Suitable examples of this type of dot printer include thermal printers and wire dot printers.

The operation of such a configuration will be explained.

The code signal generator 10 sends out scale code signals and tone length code signals corresponding to musical tone signals, and these code signals are sent to the musical score pattern synthesizer 2.
It is input to 0. In the musical score pattern synthesizer 20,
Musical score patterns corresponding to musical tone signals are synthesized based on these code signals, and these synthesized musical score patterns are sent to the recording device 30. That is, in the musical score pattern synthesizer 20, the arithmetic control section 24
In the main routine, the recording device 30 is controlled. When it becomes necessary to synthesize a musical score pattern, the process jumps to the synthesis subroutine, takes in the scale code signal and note length code signal, performs various synthesis operations based on these code signals, and stores the musical tone signal in the storage section 23. Create a corresponding score pattern. When the synthesis work is completed, the arithmetic control section 24 returns to the main routine, and the storage section 2
3 is read out and recorded by the recording device 30. After all musical score patterns in the storage section 23 have been recorded, the program jumps to the synthesis subroutine again and takes in a code signal corresponding to the next tone signal.

FIGS. 2a to 2c each show an example of synthesizing musical score patterns. Figure 2a is an example of a treble clef. When a predetermined code signal representing a symbol is input as a scale code signal and a predetermined code signal representing a treble clef symbol is input as a tone length code signal, after clearing the storage section 23, the pattern signal generation section 22 outputs a predetermined code signal representing a symbol. The treble clef pattern is loaded into the storage unit 23. In this embodiment, since the treble clef is stored in the pattern signal generation unit 22 in a form superimposed on a five-line staff, it can be sent to the recording device 30 immediately after being imported into the storage unit 23. Measure separation lines, time signatures, etc. can also be processed in the same way as the treble clef. Figure 2b shows an example of a quarter rest. When a predetermined code signal representing a rest is input as a scale code signal and a predetermined code signal representing a quarter rest is input as a tone length code signal, after clearing the storage section 23, the pattern signal generating section The quarter rest pattern from 22 is stored in the storage unit 23.
taken within. In this example, the quarter rest is 5
Since it is stored in the pattern signal generation section 22 in a form without a line score, after it is imported into the storage section 23, it is shifted by a predetermined number of bits so as to correspond to a 5 line score. Thereafter, the 5-line score is superimposed to complete the pattern synthesis, and the system is ready to be sent to the recording device 30. FIG. 2c shows an example of a dotted quarter note whose scale is C and has a natural symbol. A predetermined code signal representing C having a natural symbol is input as a scale code signal, and a predetermined code signal representing a dotted quarter note is input as a tone length code signal. First, the addition of a natural symbol is identified from the scale code signal, and the natural symbol pattern is synthesized and recorded. Next, the quarter note is identified and taken into the storage unit 23, shifted to a position corresponding to the C scale, and superimposed on the five-line staff. Furthermore, the notation is identified and added, and an auxiliary line corresponding to C is added to the bottom of the five-line staff. In this manner, when the musical note pattern of a dotted quarter note having a C scale and a natural symbol is synthesized, it is sent to the recording device 30.

In addition, in the examples shown in Fig. 2, in order to explain the musical score pattern synthesis procedure, an example is shown in which musical score information patterns are synthesized and recorded for each musical tone signal for convenience, but in reality, as described above, the musical score information pattern is synthesized and recorded. In the storage section 23, musical score patterns are synthesized and edited in units of blocks according to the number of musical tone signals set in advance, and are recorded in units of blocks.

With this configuration, it is possible to superimpose and edit a plurality of musical score patterns at any arbitrary position in the storage unit 23, and it is possible to record a complex musical score.

In addition, a musical score information pattern that does not have a 5-line staff and is stored as a dot pattern in the pattern signal generation unit 22 is replaced with a first chord signal that includes information that corresponds to the scale of the musical tone signal and information that corresponds to the note length. Since it is specified by the second code signal and selectively read out, the same musical score information pattern can be used even if the musical tone signals have different scales, as long as they have the same length, which saves the memory capacity of the pattern signal generator 22. can.

Further, if necessary, a CRT display may be added to output the state of the composite pattern in the storage unit 23, and missing pattern information may be added by manual operation while monitoring this output image. You can also do it.

Furthermore, by adding a terminal device that performs automatic performance based on the recording results of the recording device 30, the recording results can be reproduced and checked at any time.

As explained above, according to the present invention, even complex musical scores corresponding to musical tone signals can be automatically synthesized, edited, and recorded using musical score information patterns stored in a relatively small-capacity memory. , useful for performance analysis and music education.
