Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a musical note creation device that can automatically create a musical note t'# when a musical tone is manually generated.

If he doesn't play his favorite song, he records the song on a tape recorder, repeats parts of it, and then repeats the song without checking the length. It is common practice to carry out a survey and then have a price meeting.

The present invention provides a completely new chestnut mark creation device that can perform the easy-to-understand marking work visually. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the drawings showing embodiments thereof. FIG. 1 is a block diagram 1 showing the overall configuration of a chestnut mark producing apparatus according to the present invention. The musical sound 1i collected by the microphone 1 is inputted to the pitch extractor 3 by the amplifier 2V (increased to a certain level at 1 interval).

The pitch extraction device 3 is of a type known as a human voice extractor, and the pitch extraction device 3 is input by a Fourier pitch device 31Vc.
The spectrum is calculated by the autocorrelator 32, the correlation of the spectrum is taken, and the pitch extraction 33t (the pitch is calculated and the pitch σ as shown in FIG. 2) is sent to the note creation device 4. Output, output, etc. O b stone creation table 4 consists of a microprocessor, etc., and is easy to use.
21 - The two middle cars, the sieve and the length of the sound, are υ
After a pause about the simplicity of the 01 sound that makes up the cup, I find that although it is not necessarily the case that the music that is performed manually is based on the master's wisdom, tuning, and moxibustion techniques, it is not necessarily the case that the sound is refined. , the data of pitch extraction table 3 output is expressed as f-Δf-f by adding an appropriate tolerance ΔfQ(Z) to the front height f(HZ) of each note of the staff member.
For those in the range of +Δf, the pitch is determined by assuming that the pitch of the note is "Q". In the example of Fig. 2, Vif, -Δf1~
Data Vif in the range of f1+Δf1,, f2−Δf2~
The data in the range f, +Δf2 is assumed to be f2, and the input musical tone is processed as quantized data as conceptually shown in FIG. There is no doubt that the data on the brightness of the tone converted into percentages corresponds to the sieve σ of the tone on the tone I station.

Next, the determination of the length of a sound will be explained. This is a 5-key human-powered device that is VC-enabled to input the actual time of a specific note into the note creation device 4 using a keyboard.

For example, it would be nice to have a 32nd note in real time T'u. In other words, T32 tl for songs with a fast tempo.
In short and slow songs, T, Vi, and Vi are held for a long time.0Also, the metronome speed (for example, J = 108) that provides reference time information for the sharpness of the sound, such as T3□.
In case of 108 input with 7 ohms, T3□=0.
07 seconds), similar data processing is performed.

Music note creation hk! ＋ll! 14 counts the number of pulses with internal illumination of T, l, which is determined as described in -11, and the number of pulses in which the next shin of Vi is inputted, using a counter; If the dI number II is 1, then 3 for the note of that pitch.
If the number is 2, use the 16th note; if the number is 3, use the diagonal or sixteenth note; if it is 8, use the quarter note... In this way, the type of i-ladle corresponding to the notation system is ^・1. In addition, depending on the playing method, Ll 呆i- may not last long enough, so in terms of the board, counter 1 is used to determine the line type of the note.
H+, ? for several kl, until the next sieve changes or the next sound is input. R, and the persimmon Dr of the note is determined by the count-up value, and if the stone is not lifted manually by U at the time specified by the data entered separately from the input device 5, this is the case. Gives a rest for a silent state 0 In this way, a note is created = position 4 K is determined by tr b - Data regarding the daytime of the fall and the type of note V1
It is output to the f-th printer 6. Pudding Ri6 tJ
As shown in the 4th PC, the example is 5 in the dot matrix.
At the same time as printing # or the upper and lower refinement, on this 5 line, at the position corresponding to the human-generated sound simplicity data, add a note pattern corresponding to the divine data of the note that was also input. With the imprint function 7-'l, the musical notes are created one after another visually as the music notes are input.

Information on meters such as 4/4 and 678 was originally created by me.

Inputting information about the 9th movement or calculating the strong dog change of the input musical tone, and from this result, calculating the size of each small trade 1. Print the 4@枳 of the bar break by a special method! Pitch (I11 output device and the pitch extraction table 16 output to indicate the input musical tone one pitch above) a note creation table that determines the type of note and a printer that outputs the content determined by the note creation table in the form of a cedar image. Therefore, anyone can easily and quickly mark notes, omitting the uninteresting work of manually crossing out notes, and making the first four notes with notes in the old days.
