Abstract

PURPOSE:To use musical score information to search a halfway position of music and improve the operability by providing a memory where correspondence relations between time information and musical score information are stored preliminarily and inputting musical score information to read corresponding time information and searching a program on a tape. CONSTITUTION:After time absolute information and musical score information are allowed to correspond to each other and are stored in a corresponding memory 23, search of an objective music is displayed in a form of musical score information like the measure number and the beat number. When a locate button 8 is depressed thereafter, a CPU 21 searches the corresponding memory 23 to find time information in a position corresponding to musical score information and gives a rewinding or fast-forwarding signal to a tape recorder 12 through a cable 11. The CPU reads time information recorded on the tape and takes in it through the cable 11 and stops running of the tape in the tape recorder 12 when this time information coincides with preliminarily searched time information. Thus, musical score information is used to search a halfway position of the music in the tape recorder, and the operability is improved considerably.

Description

[Detailed description of the invention] (Industrial application field) The present invention allows music to be recorded in a studio or the like.

The present invention relates to a tape locating device used for editing, and more specifically to a tape locating device that can accurately perform cueing, partial erasure, recording, etc. of a tape recorder using musical score information such as measures and notes.

(Prior art) In recording studios, etc., multi-track (for example, 8
Vocals, musical instruments, etc. are recorded independently on a tape recorder (channel), and then converted to a two-channel stereo signal using a mixer to obtain the final music information signal. Recently, a time code called SMPTE has been recorded on recording tapes in parallel with audio recording in order to synchronize multiple recorders and to locate/edit accurate positions. This time code records time and other information (eg, frame number, subframe number) for each unit area in an 80-bit data area. A tape locate device is a device used for recording and reading out such time codes.

FIG. 3 is a diagram showing an example of the external configuration of the tape locating device. In the figure, 1 is an information display section that displays time information or music information, 2 is a numeric keypad for setting time information, memory number, etc., 3 is a function key consisting of various control keys, and 4 is a function key that is set by the function key 3. 5 is a tape recorder operation key for remotely controlling the tape recorder (not shown); 6 is a store (STORE) for storing time information, etc. in the built-in memory; button, 7 is a recall (RECALL) button for reading out time information etc. stored in the built-in memory to the information display section 1, and 8 is the information display section 1
Location-1 to (LO

A tape locating device with such a configuration rI! t10 is the fourth
tape recorder 1 via cable 11 as shown in the figure.
It is used in connection with 2. With the cable 11 connected, the tape recorder 12 can be remotely operated using the recorder operation key 5 of the tape locating device 10. Then, set the tape position to the initial position, for example, set the information display section 1 to "'00"H"O○II M
Set to ``oo''s, turn on J3, and start recording.

In addition to music information, absolute time information is recorded in the SMPTE code for each unit area on the tape during recording. That is, in this case, the time information signal generated by the tape locating device 10 is transmitted to the tape recorder 12 via the cable 11.
and recorded on tape. In this case, the recording method is, for example, pi-phase-'? -ri (B 1pha
se - Mark ) method is adopted. in this way,
Time information can be recorded together with music information.

In such a recording method, the time information is essentially the position information of the music recorded on the tape.

Usually, most recording stations use the same tape to record multiple songs. Therefore, the time information of the beginning of the first song, second song, etc., and the beginning of the song are stored in the memory built into the tape locating device 10 with memory numbers 1 and 1, respectively. Memory number 2・
..., and if necessary, call up a predetermined number in the memory number (hereinafter simply referred to as memory NO3) and perform fast forwarding or rewinding until the tape position reaches the relevant time information. You can cue up.

The operation for storing the beginning position of a song in memory is as follows. For example, load a tape into the tape recorder 12, and use the numeric keypad 2 to display a predetermined time on the information display section 1, such as 'o o ``to1'' o o ``M''00.
"S" is displayed.Next, press the store button 6 and press a predetermined number button (for example, 1) on the numeric keypad 2, and the time information displayed on the information display section 1 will be displayed in the area corresponding to memory No. 1. is stored as the starting position of the song.

Such a memory operation is performed for each side. When you want to output the Nth (N is an integer) song recorded on the tape, first press the recall button 7! After,
Press the number button corresponding to memory No. "N" using the numeric keypad 2, and then press the locate button 8. Therefore,
The tape locating device 10 sends a control signal such as a fast forward or rewind signal to the tape recorder 12 to fast forward or rewind the tape and search for the beginning position of a song. and,
When the tape reaches a predetermined cue position, the rotation of the reel is stopped. Thereafter, reproduction or recording of new music information is performed as necessary. A similar operation can be applied to the case where one song is divided into measures, for example, and the cue is searched from an arbitrary measure portion.

(Problem to be Solved by the Invention) In conventional devices of this type, music information recorded on tape and electronic musical instruments may be operated simultaneously from the beginning of the song and input into a mixer to perform mixdown. . According to the conventional method, since there is no absolute address in the music information, it is not possible to play back the tape or play the music from the middle. In normal editing work, in most cases only the poor performance range is re-recorded or re-edited, so conventional devices that cannot play tape from the middle of a song have extremely poor operability.

The present invention has been made in view of these points, and
The purpose is to realize a tape locating device that improves operability by making it possible to locate the beginning of a song from the middle using score information.

(Means for Solving the Problems) The present invention solves the above problems by reading time information from a tape on which time information is recorded together with music information,
In a tape locating device that can accurately search for a target tape position, time information and musical score information (measure 2 time.

Equipped with a memory that stores the correspondence of musical notes in advance,
The present invention is characterized in that it is configured to input musical score information and read the corresponding time information to locate the beginning of the tape.

(Operation) The present invention establishes a correspondence between absolute time information and musical score information, so that it is possible to locate the beginning of a song from musical score information.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an electrical configuration diagram that does not show one embodiment of the present invention, and the mechanical components are omitted. Further, electrical components not directly related to the present invention are also omitted. Components that are the same as those in FIGS. 3 and 4 are designated by the same numbers. In the figure,
20 is a keyboard interface that receives contact signals from the numeric keypad 2° store button 6, recall button 7, and locate button 8 and converts them into corresponding codes (for example, ASCII codes); 21 is a C that performs various calculations 1bl1m;
PU, 22 is a memory for recording the above-mentioned time information, sequence programs, etc., and 23 is a corresponding memory in which time information and musical score information are stored in association with each other as shown in FIG. In FIG. 2, A is the time information section, B
is a musical score information section in which corresponding musical score information is recorded. Here, as for the musical score information, only the musical score information such as the number of measures and musical notes is recorded, as shown in the figure, and the musical intervals (scales) are not recorded. The CPU 21 and the keyboard 20 and the CPU 21 and the memories 22 and 23 are connected by digital buses, respectively. The CPtJ 21 is connected to a tape recorder 12 (FIG. 4) via a cable 11. 24
is a display interface that performs control to display time information or musical score information output from the CPLI 21 on the information display unit 1. The operation of the device configured as described above will be explained as follows.

First, the operation for locating the beginning position of the tape will be explained. In this case, the apparatus of the present invention and the tape recorder 12 are connected by a cable 11. The operator is
Once the beginning position of the tape is determined on the tape recorder 12, time information is set using the numeric keypad 2. The set time information is stored in the keyboard interface 20.
It is stored in the memory 22 via the CPtJ21. CPU
21 sends the time information stored in the memory 22 to the display interface 23. The display interface 23 causes the time display section 1 to display the input data.

Next, the time information set in this way is stored in the memory 2.
2, press the store button 6 and then press the number button corresponding to memory No. 1 on the numeric keypad 2. The time information displayed on the time display section 1 will be stored in the corresponding area of the memory 22. be done. This storage operation is repeated as many times as necessary.

When the starting position of the song is stored in the memory 22, the user presses the recall button 7, then presses memory No. 1 on the numeric keypad 2, and finally presses the locate button 8.

As a result, a control signal for locating is output from the CPU 21 to the tape recorder 12 via the cable 11.

Next, the operation when reproducing recorded music information will be explained. The first method is to reproduce music information using the same operations as when recording music information. Specifically, after displaying absolute time information on the information display section 1 using the recall button 7 and the numeric keypad 2, the locate button 8 is not pressed. Thereby, the CPU 21 remotely controls the tape recorder 12 via the cable 11 to perform rewinding or fast forwarding, and reads out the SMPTE code recorded on the tape and imports it into the tape. Then, when the captured time information matches the time displayed on the information display section 1, the running of the tape is stopped. At this time, the tape recorder 12 stops at a predetermined tape cue position and becomes ready for recording or playback. This operation allows you to locate the beginning of the tape.

The second method is unique to the present invention. When performing a recording operation, the relationship between time information and musical score information as shown in FIG. 2 is previously stored in the correspondence memory 23 for one song. The storage operation is performed using the numeric keypad 2, function keys 3 (see FIG. 3), and the like. For example, the absolute time "'X
"H"Y"M"Z"'S is stored in correspondence with the beat of the measure and so on.The music score information only stores the 9 time signature of the measure, the @ sign, etc. Yes, there is no need to memorize the note l\ (scale).

After the absolute time information and musical score information are stored in association with each other in the correspondence memory 23 in this way, the recall button 7 is pressed.
Using the numeric keypad 2 and other function keys 3, the information display unit 1 displays the starting position of the target song in the form of musical score information, which bar and beat. Thereafter, when the locate button 8 is pressed, the CPU 21 searches the corresponding memory 23 to find time information at a position corresponding to the musical score information. If you can find the time information, cable 11
A control signal such as a rewind or fast forward signal is applied to the tape recorder 12 via the tape recorder 12. Then, the time information recorded on the tape is taken into the device via the reading cable 11.

When the captured time information matches the time information found in advance, the tape running of the 12 tape recorders is stopped. The tape recorder 12 waits in the stopped state, and the beginning of the tape has been found. After that, playback or playback/recording can be performed from this tape position. As described above, according to the present invention, the position of the tape can be determined using the musical score information, and the beginning can be found from the middle of the song, so the operability is greatly improved.

Above) In the explanation of E, we will take as an example the case where absolute time information and musical score information are stored in association with each other, and when musical score information is given, the corresponding time information is searched and the tape position is located from the time information. explained. However, the present invention is not limited to this. In SMPTE recording, absolute time information and music signals are recorded in parallel on a tape. Therefore, if the tempo, number of bars, and note types of the song are known, absolute time information can be calculated from the set score information. In this way, the beginning of a song recorded on a tape may be found.

<Effects of the Invention> As described in detail above, according to the present invention, musical score information can be stored by providing a memory that stores absolute time information recorded on a tape in association with musical score information in advance. For example, by specifying the beat of the measure, the absolute information of the corresponding time can be easily determined. Therefore, according to the present invention, music information can be used to locate the beginning of a tape recorder even from the middle of a song, and operability is greatly improved.
