BEST MODE FOR CARRYING OUT THE INVENTION A. First Embodiment FIG. 1 is a block diagram showing the arrangement of a musical sound reproduction / recording apparatus 600 according to the first embodiment of the present invention. In FIG.
The CD drive device 1 follows the instruction from the controller 4,
This is a device that reads out and outputs recorded data from a mounted CD. Various CDs can be mounted on the CD drive device 1. Of these CDs, the one most strongly related to the present invention is the CD whose main recording data is time-series audio data which is music data. As shown in FIG. 2, the music data includes a coded data string (audio data) of an audio signal generated in association with an orchestra performance or singing of a certain music. Further, time codes are discretely inserted in this music data. These time codes are codes indicating the elapsed time from the start of the music.
A CD in which data of a type different from such data is recorded can also be loaded in the CD drive device 1. For example, time-series audio data is recorded as L channel data, and MI for automatic performance control is recorded as R channel data.
A CD on which DI data is recorded can be loaded into the CD drive device 1. On the contrary, a CD in which time series audio data is recorded as R channel data and MIDI data for automatic performance control is recorded as L channel data is C
It may be mounted on the D drive device 1.

The DSP 2 sets the time code included in the music data read from the CD drive 1 to 250 mse.
It is delayed by c and sent to the controller 3, and similarly delayed by 250 msec to generate an analog audio signal from the audio data in the music data and send it to the mixer 5. In this way, the music data is 250 msec
The analog audio signal is sent to the mixer 5 with a delay only by the fact that the CD loaded in the CD drive device 1 is a normal C
This is because the time required for determining whether it is D and the type of data reproduced from the CD is taken into consideration. That is, if an analog audio signal is immediately generated from audio data and sent to the mixer 5 without making such a determination, an abnormal musical sound may be generated. In view of such circumstances, the DSP 2 according to the present invention
Determines whether or not the CD mounted in the CD drive device 1 is a normal CD, and only when it determines that the CD is a normal CD, the mixer 5 outputs the generated analog audio signal.
Meanwhile, the controller 3 is notified of the type of data reproduced from the CD (for example, the data reproduced from the CD is time-series audio data and does not include MIDI data).

Further, the DSP 2 is provided with identification information for identifying a CD selected by the user by operating the operation unit 4 from among a plurality of CDs mounted in the CD drive device 1 (hereinafter referred to as C-ID as appropriate). CD) and identification information (hereinafter, appropriately referred to as M-ID) for identifying the music data selected from the plurality of music data stored in the CD.
It is acquired from the driving device 1 and sent to the controller 3. In the present embodiment, the case where the DSP 2 acquires the identification information for identifying the CD selected by the user and the identification information for identifying the music data from the CD drive device 1 will be described as an example. Only one identification information (for example, identification information for identifying the CD) may be acquired.

The controller 3 controls the entire music reproducing apparatus according to an instruction given through the operation unit 4. Of the various controls performed by the controller 3, the one most closely related to the present invention is the recording control when the CD is reproduced and the synchronous recording is performed. The "synchronous recording" in the present invention does not record both the reproduced sound of the CD and the musical sound of the electronic piano 10 played by the user.
This is to record only the performance sound when the user plays the electronic piano 10 along with the reproduction of D. When this synchronous recording instruction is given from the operation unit 4, the controller 3
Sends an instruction to reproduce the music data to the CD drive device 1 in accordance with this instruction. Also, the controller 3 sets the time code to F each time it receives the time code from the DSP 2.
Along with sending to the D recording device 8, MIDI events and the like (described later) sequentially supplied from the MIDI event generating circuit 14 are sent to the FD recording device 8. Note that these means will be described later.

The electronic piano 10 is provided with a musical tone generating mechanism for generating a mechanical piano sound by striking a string in response to a key operation by the user, and also detects a key operation by the user, and an electronic piano according to the detection result. It also has a sound generation mechanism that generates sounds. The electronic piano 10 has a piano 11
, Key sensor 12, pedal sensor 13, MIDI
It has an event generation circuit 14 and a piano sound source 15. The key sensor 12 and the pedal sensor 13 are provided corresponding to each of a plurality of keys and a plurality of pedals (such as a sostenuto pedal) arranged on the piano 11, and the strength and depth when the key and the pedal are pressed. And the like, and the detected result including the key number or pedal number for specifying the detected key or pedal, velocity information (data corresponding to the key pressing strength, etc.), etc.
Supply to.

The MIDI event generation circuit 14 generates a MIDI event based on the detection results supplied from the key sensor 12 and the pedal sensor 13 under the control of the controller 3. Here, the MIDI event is shown in FIG.
As shown in FIG. 5, note-on / note-off information indicating that sounding or mute should be performed, note number information indicating the pitch of a sound to be sounded, velocity information indicating strength of sounding, and the like. MIDI event generation circuit 14
Generates a MIDI event, which is a kind of event instructing performance control, such as "pronounce note (note number) with a strength of 10 (velocity) (note on)", based on the detection result. The MIDI event is supplied to the controller 3 and the piano sound source 15.

The piano sound source 15 is a device for electronically generating an analog audio signal of a piano sound designated by an event supplied from the MIDI event generation circuit 14. The analog audio signal generated by the piano sound source 15 is output to the mixer 5. Mixer 5
Is a device that mixes and outputs the analog signals output from the DSP 2 and the piano tone generator 15. The output signal of the mixer 5 is amplified by the amplifier 6 and output as sound from the speaker 7.

The FD recording device 8 outputs the performance sound when the user plays the electronic piano 10 along with the reproduction of the CD, that is, the performance sound of the electronic piano 10 by the user to the FD (Floppy).
Under the control of the controller 3, identification information (C-ID) for identifying the CD supplied from the controller 3 and identification information (M-ID for identifying the music data). ), And has a function of creating an SMF (Standard MIDI File) including MIDI events and the like. Here, the SMF is composed of a header chunk HT and a track chunk TT, as shown in FIG. The header chunk HT stores basic information of the SMF (chunk type, etc.) and also has CI
Identification information for identifying a CD and music data to be reproduced during synchronous recording such as D and M-ID is stored. MIDI data is stored in the track chunk TT.
As shown in the figure, the MIDI data is time-series music data composed of an event instructing performance control and the like, and a delta time indicating an occurrence time interval between a preceding event and a subsequent event. Here, the events that compose the MIDI data are composed of MIDI events generated by the MIDI event generation circuit 14, SysEx events generated by the controller 3, and meta events.

Upon receiving the synchronous recording start command from the controller 3, the FD recording device 8 for creating and recording the SMF starts time counting using a time measuring means (described later). Then, each time the FD recording device 8 receives an event from the controller 3, the FD recording device 8 obtains the delta time by referring to the time and the like measured by the time measuring means, and sequentially creates MIDI data including the event and the delta time (FIG. 4).
reference). Here, the FD recording apparatus 8 according to the present invention, under the control of the controller 3, reproduces the start event (reproduction of the music data stored in the CD at a position corresponding to the time point when 250 msec has elapsed from the beginning of the music in the MIDI data. It has a function to insert a start event). Further, the FD recording device 8 records the performance sound of the electronic piano 10 in synchronization with the reproduction of the time-series audio data by the CD drive device 1, and the time measured by the time measuring means and the time supplied from the controller 3. It has a function of appropriately adjusting a delta time value indicating an occurrence time interval between a preceding event and a subsequent event in accordance with a deviation generated from the time indicated by the code. The configuration of the FD recording device 8 having such various functions will be described below with reference to FIG.

FIG. 5 is a block diagram for explaining the configuration of the control circuit provided in the FD recording device 8. The control circuit shown in FIG. 5 has a function of creating the SMF described above and recording the SMF in the FD, and a time measured by the time measuring means 220 and a time indicated by the time code supplied from the controller 3. It has a function of correcting a gap generated between them. The clock generation means 210 is provided in the controller 3 and includes an oscillation circuit (both not shown) configured by a crystal oscillator and an amplifier.
Clock generation means 2 provided in this controller 3
Reference numeral 10 appropriately divides the oscillation signal obtained from the oscillation circuit to generate various clocks for timing control. Among these various clocks, the tempo clock CT is one that is closely related to the present invention.

The clock means 220 comprises an adder 221 and an elapsed time register 222. The adder 22
1 and elapsed time register 222 allows tempo clock C
An accumulator is configured to add "+1" each time T is given. The adder 221 adds the data stored in the elapsed time register 222 and the fixed value “+1” and outputs the result. An initial value “0” is written in the elapsed time register 222 when the synchronous recording is started, and thereafter, every time the tempo clock CT is given to the elapsed time register 222, the output data of the adder 221, that is, the time The result of addition of the data stored in the elapsed time register 222 and "+1" is written. The output data N of the elapsed time register 222 is used as elapsed time data representing the elapsed time after the start of synchronous recording.

The SMF creation / writing control means 250 is
Under the control of the controller 3, the SMF creation and the control for writing the created SMF in the FD mounted on the FD recording device 8 are performed. More specifically, when the SMF creation / writing control means 250 first receives the identification information (C-ID, M-ID, etc.) for identifying the CD and music data reproduced from the controller 3 during the synchronous recording. The received identification information is stored in the header chunk HT (see FIG. 4). After that, SMF creation / writing control means 25
0 receives a variety of events (such as MIDI events) generated by the MIDI event generation circuit 14 and the like from the controller 3, and sends a command to the delta time generation means 240 to generate a delta time.

Upon receiving such a command, the delta time generation means 240 generates delta time (details will be described later) and returns it to the SMF creation / writing control means 250. The SMF creation / writing control means 250 stores the MIDI data composed of the delta time received from the delta time generation means 240 and the event received from the controller 3 in the track chunk TT (see FIG. 4) to create the SMF, This is written in the FD mounted on the FD recording device 8. In addition to the processing described above, the SMF creation / writing control means 250 refers to the time measured by the time measuring means 220, etc., and reproduces the start event (CD) at the position corresponding to the time 250 ms after the beginning of the song in the MIDI data. The process of inserting an event for instructing the start of the reproduction of the music data stored in (1) is also executed.

The delta time generation means 240 includes a previous elapsed time register 241 and a correction value register 242, and generates a delta time based on a command from the SMF creation / writing control means 250. In the previous elapsed time register 241, the SMF creation / writing control means 2 is set in the previous time.
The elapsed time data (referred to as Nf for convenience) acquired from the timing means 220 when the command to generate the delta time is received from 50 is held. The initial value “0” is written in the previous elapsed time register 241 when synchronous recording is started.

The correction value register 242 holds the correction value R of the delta time generated by the delta time adjusting means 230. As will be described in detail later, by appropriately setting the correction value R in the correction value register 242, the deviation caused between the time measured by the time measuring means 220 and the time indicated by the time code supplied from the controller 3 is generated. To correct. An initial value “0” is written in the correction value register 242 when synchronous recording is started.

When the delta time generation means 240 receives an instruction to generate delta time from the SMF creation / writing control means 250, it acquires the elapsed time data N at the present time stored in the elapsed time register 222 from the timing means 220. After that, the elapsed time data Nf held in the previous elapsed time register 241 (the elapsed time acquired from the time measuring means 220 when the instruction to generate the delta time from the SMF creation / writing control means 250 was received last time) is obtained. The elapsed time data Nf is subtracted from the read and elapsed time data N. Then, the delta time generating means 240 reads the correction value R of the delta time held in the correction value register 242, adds this correction value R and the subtraction result N-Nf, and adjusts the addition result N-Nf + R. The later delta time is returned to the SMF creating / writing control means 250. Then, the delta time generation means 24
0 updates the elapsed time data stored in the previous elapsed time register 241 to the elapsed time data newly acquired from the clock means 220 this time.

The delta time adjusting means 230 causes a discrepancy between the time measured by the time measuring means 220 and the time indicated by the time code supplied from the controller 3 in order to perform recording in synchronization with reproduction of the CD. The delta time value indicating the time interval between the preceding event and the subsequent event is adjusted accordingly.

FIG. 6 is a flowchart showing the delta time adjustment processing executed by the delta time adjustment means 230. When a time code larger than "0" is given from the controller 3 in step S1, the delta time adjusting means 230 sets this as the first recording time data TCD, and proceeds to step S2. When the delta time adjustment means 230 proceeds to step S2, the time measurement means 220
Then, the elapsed time data N at that time is acquired, and the acquired elapsed time data N is multiplied by the period τ of the tempo clock CT to obtain the second recording time data TFD (= N * τ). The second recording time data TFD represents the elapsed time from the start of synchronous recording to the present.
Next, the delta time adjusting means 230 determines whether or not the absolute value | TCD-TFD | of the difference between the first recording time data TCD and the second recording time data TFD is within a preset allowable range Δ. Whether or not (step S
3). When the delta time adjusting means 230 determines that the absolute value of the difference between the first recording time data TCD and the second recording time data TFD is within the predetermined allowable range Δ (step S3; YES), the delta time “0” is written in the correction value register 242 as the correction value R of (step S4), and the delta time adjustment processing ends.

On the other hand, the delta time adjusting means 230 includes the first recording time data TCD and the second recording time data TF.
If it is determined that the absolute value | TCD-TFD | of the difference of D exceeds the predetermined allowable range Δ, the first recording time data T
It is determined whether the CD is larger than the second recording time data TFD (step S5). When the first recording time data TCD is larger than the second recording time data TFD, it can be said that the time measured by the time measuring unit 220 is behind the time indicated by the time code supplied from the controller 3. . Delta time adjustment means 2
30 determines that the first recording time data TCD is larger than the second recording time data TFD (step S
5; YES), the difference between the second recording time data TFD and the first recording time data TCD is calculated in order to correct the time shift by reducing the delta time, and the calculated difference TFD-TCD (<0) Is the period τ of the tempo clock CT
The division result (TFD-TCD) / τ
Is written in the correction value register 242 shown in FIG. 5 as the correction value R of the delta time (step S6), and the delta time adjustment processing is ended. In this case, the delta time correction value R written in the correction value register 242 is a negative value.

On the other hand, the first recording time data TCD is the second
If it is smaller than the recording time data TFD of
It can be said that the time counted by 20 is ahead of the time indicated by the time code supplied from the controller 3. When the delta time adjusting means 230 determines that the first recording time data TCD is smaller than the second recording time data TFD (step S5; NO), the delta time should be corrected by increasing the delta time. The difference between the second recording time data TFD and the first recording time data TCD is calculated, and the calculated difference TFD-TCD
(> 0) is divided by the period τ of the tempo clock CT, and the division result (TFD-TCD) / τ is used as a correction value R for the delta time, and the correction value register 242 shown in FIG.
(Step S7), and the delta time adjustment process ends. In this case, the correction value R of the delta time written in the correction value register 242 is a positive value. The above is the details of the musical sound reproduction / recording apparatus 600 according to the present embodiment. Hereinafter, with reference to FIG.
The operation of 00 will be described in detail.

FIG. 7 is a time chart showing the operation of the music reproducing apparatus according to this embodiment. More specifically, in FIG. 7, a time code read from the CD, audio data read from the CD, and the DSP 2 are shown in FIG.
Audio data read from the MIDI event ME, the time measured by the time measuring means 220 of the FD recording device 8, and the MIDI event ME generated by the MIDI event generation circuit 14.
-N (n = 1, 2, ...) Is shown in time series. In FIG. 7, a [k] (k = 0, 0.25, 0.
5, 5) are audio data of a part within a section from k seconds to k + 1 seconds when the start time of the music is 0 seconds. Also, r [k] (k = 0, 0.25, 0.5, ~)
Is the time measured by the time measuring means when k seconds have elapsed when the start time of the music is 0 seconds. Further, in the example shown in FIG. 7, the time code is C every 250 msec.
Played from D.

First, the user operates the operation unit 4 to reproduce a C from a plurality of CDs mounted on the CD drive device 1.
Select D and song data. When the controller 3 receives the instruction of the CD and the music data to be reproduced via the operation unit 4, the controller 3 sends the CD drive device 1 a read command of the identification information for identifying the CD and the music data. The CD drive device 1 follows the instruction to identify information (C-ID, M-ID) for identifying the CD and the music data.
ID) is read and sent to the controller 3 via the DSP 2. The identification information is transferred from the controller 3 to the FD recording device 8 and stored in the header chunk HT of the SMF by the FD recording device 8 (see FIG. 4).

After that, when the user operates the operation unit 4 to give an instruction to the controller 3 to start the synchronous recording, the controller 3 causes the CD
An instruction to reproduce music data is sent to the driving device 1. Upon receiving the reproduction instruction from the controller 3, the CD drive device 1 immediately reads out the audio data a [0] and the time code “0” of the beginning portion of the music from the CD and sends them to the DSP 2.
When 250 msec has passed, the audio data a [0] and the time code “0” are changed to DSP2.
Are output to the mixer 5 and the controller 3, respectively. The DSP 2 determines the type of data reproduced from the CD, whether the CD is normal, etc. by using the time of 250 msec in which the audio data a [0] is delayed, and the determination result Is notified to the controller 3. In this case, the controller 3 determines that the music data reproduced from the CD is time-series audio data, and M
You will receive a notification that it does not contain IDI data and that the CD is normal.

Upon receiving the notification and the time code "0" from the DSP 2, the controller 3 sends the FD recording device 8 together with the time code "0" and an instruction to start synchronous recording. Upon receiving the synchronous recording start instruction from the controller 3, the FD recording device 8 immediately starts time counting using the time counting means 220. However, the delta time adjusting means 230 in the FD recording device 8 does not adjust the delta time using this time code “0”. After that, when 250 msec has elapsed, the DSP 2 outputs the time code "0.25". At this time,
Since the time code larger than "0" is supplied to the delta time adjusting means 230, the delta time is adjusted as described above.

Therefore, when 250 msec has passed since the instruction to reproduce the music data was sent to the CD drive device 1, the reproduction of the music data and the recording of the performance sound by the FD recording device 8 are simultaneously started. And further 250 mse
When c has elapsed, the delta time adjusting means 230 appropriately adjusts the value of the delta time according to the difference between the time measured by the time measuring means 220 and the time indicated by the time code supplied from the controller 3. Start the delta time adjustment process. Then, thereafter, each time the time code is supplied from the DSP 2, the delta time adjusting means 230 adjusts the delta time described above. After that, for example, as shown in FIG. 7, MIDI events ME-1, -2, and -3 are generated at the clock times r [1.0], r [1.5], and r [2.0] by the clock means 220. ,
When the delta time corresponding to each MIDI event is generated, these are supplied to the SMF creation / writing control means 250.

The SMF creation / writing control means 250 is
MIDI events ME-1, -2, -3 and each MIDI
Each MI when receiving the delta time corresponding to the event
The MIDI data including the DI event and each delta time is stored in the track chunk TT of the SMF. And
The SMF creation / writing control means 250 writes the SMF composed of the above-mentioned header chunk HT and track chunk TT to the FD mounted in the FD recording device 8, and ends the processing. As is apparent from the above description, the feature of the present invention resides in that the time management of the synchronous recording is performed based on the time code read from the storage medium such as the CD. It should be noted that the configuration, operation, and the like of the music reproducing device that synchronously reproduces the MIDI data recorded in the FD and the music data stored in the corresponding CD will be described in detail in the second embodiment. .

As described above, according to the musical sound reproduction / recording apparatus 600 of the present embodiment, both the reproduced sound of the CD and the performance sound of the electronic piano 10 by the user are recorded when recording is performed in synchronization with the reproduction of the CD. Is not recorded in FD, but C
Along with the reproduction of D, only the performance sound when the user plays the electronic piano 10 is recorded in the FD. Therefore, even if the audio data stored in the CD is stereo-recorded audio data, it is not necessary to perform monaural conversion or the like, and the problem that the spread of sound cannot be obtained (see the section of the prior art) is solved. be able to. Further, in this way, only the performance sound when the user plays the electronic piano 10 is FD.
Since the data is recorded in, the user can hear back only his or her musical instrument performance sound by reproducing the music data recorded in the FD.

The header chunk HT of the SMF recorded on the FD stores identification information for identifying the CD or the like reproduced at the time of recording.

B. Second Embodiment FIG. 10 shows a musical sound reproducing / recording apparatus 70 according to the second embodiment.
It is a figure which shows the structure of 0. The musical sound reproduction / recording apparatus 700 according to the present embodiment has a function of recording MIDI data in synchronization with reproduction of a CD, and also reproduces music data stored in a CD corresponding to the recorded MIDI data in synchronization. It has a function to do. The tone reproduction / recording device 700 shown in FIG. 10 is different from the tone reproduction / recording device shown in FIG. 1 except that an FD reproducing device 8a is provided and an automatic piano 20 is provided instead of the electronic piano 10. It is substantially similar to device 600. Therefore, the corresponding parts are designated by the same reference numerals, and the description of the parts overlapping with those of the first embodiment will be omitted.

The controller 3 has not only the function described in the first embodiment but also a function of performing control for synchronous reproduction of CD and FD. When this synchronous reproduction instruction is given from the operation unit 4, the controller 3
In response to this instruction, the F
It is sent to the D playback device 8a. The controller 3 sends the event supplied from the FD playback device 8a to a means for performing automatic performance. Note that these means will be described later.
Further, the controller 3 causes the FD reproducing device 8a to perform C
When an event instructing to start playing D is read,
A reproduction instruction is sent to the CD drive device 1. Moreover, the controller 3 sends the time code to the FD reproducing device 8a every time the time code is read by the CD drive device 1.

The automatic piano 20 has the function as the electronic piano 10 described in the first embodiment,
MIDI read from the FD by the controller 3
It has a function to perform automatic performance according to the data. The automatic piano 20 includes the components of the electronic piano 10 (piano 11, etc.), an ensemble sound source 18, and
A piano electronic circuit 16 and a drive solenoid group 17 are provided. When performing an automatic performance with the ensemble sound source 18, the controller 3 sends the event received from the FD reproducing device 8a to the ensemble sound source 18. Further, when performing the automatic performance by the piano sound source 15 or the piano 11, the controller 3 sends the event received from the FD reproducing device 8a to the piano electronic circuit 16. Which means to perform the automatic performance is determined according to an instruction from the operation unit 4.

The ensemble sound source 18 is the controller 3
It is a device that receives an event from and generates a digital tone signal according to the event. The digital tone signal generated by the ensemble sound source 18 is converted into an analog tone signal by the controller 3 and sent to the mixer 5. The mixer 5 according to the present embodiment has both an analog input port for receiving an analog signal and a digital input port for receiving a digital signal, and mixes all signals input via these ports. Can be output. Therefore, the digital musical tone signal output from the ensemble sound source 18 is output to the controller 3
It may be directly supplied to the mixer 5 without passing through.

The piano electronic circuit 16 is a circuit that receives an event from the controller 3 and performs control for automatic performance. The piano electronic circuit 16 controls the automatic performance by one of two methods. First, the first
In this method, the event received from the controller 3 is sent to the piano sound source 15. As mentioned above, piano sound source 1
Reference numeral 5 is a device for electronically generating an analog audio signal of a piano sound designated by an event. In the second method, the piano electronic circuit 16 controls the energization of the drive solenoid group 17 according to the event received from the controller 3. The drive solenoid group 17 includes a plurality of solenoids corresponding to a plurality of keys provided on the piano 11 and a plurality of solenoids corresponding to a plurality of pedals. When the piano electronic circuit 16 receives from the controller 3 an event instructing the pressing of a certain key, a driving current is passed through the solenoid corresponding to the key, and the solenoid generates the magnetic force required to press the key. The same applies when an event instructing key release is received. An instruction to handle the event by either the first method or the second method is given from the operation unit 4 to the controller 3, and the controller 3 sends this instruction to the piano electronic circuit 16. The piano electronic circuit 16 follows the received instruction.

There is a delay from the output of the event by the controller 3 to the generation of the automatic performance sound,
The delay time differs depending on which means is used to perform the automatic performance. When playing automatically with an automatic piano,
It takes, for example, 500 msec from the controller 3 outputting the event until the automatic performance sound is generated. Therefore, in the present embodiment, when an instruction for synchronous reproduction is given from the operation unit 4 and the automatic piano is selected as a means for automatic performance, the C
Synchronous playback of D and FD is performed. First, a MIDI data reproducing instruction is sent from the controller 3 to the FD reproducing device 8a. Then, as is clear from the above, when only 250 msec has elapsed from this point in time, the event instructing the reproduction disclosure of the CD is read from the FD.
Then, the controller 3 sends a reproduction instruction to the CD drive device 1 by receiving this event.
In this way, at the timing of starting playback of FD and CD, 250
By giving a time difference of msec, MI in the FD is
The reproduction of the music by the DI data and the reproduction of the music by the audio data in the CD are started at the same time.

The FD reproducing device 8a sequentially reads the MIDI data recorded from the FD and supplies it to the controller 3 in accordance with the instruction from the controller 3. This MI
The DI data is, for example, MIDI data recorded by the FD recording device 8 in synchronization with the reproduction of the CD (see FIG. 4). After reading a certain event from the FD and sending it to the controller 3, the FD reproducing device 8a waits for the time indicated by the delta time after the event and repeats the process of reading the subsequent event. This is the basic operation of the FD reproducing device 8a. As described above, one piece of MIDI data recorded by the FD recording device 8 in synchronization with the reproduction of a CD includes an event for instructing the start of CD reproduction in addition to an event for performance control. There is. This event is inserted in the MIDI data at a position corresponding to the time point when 250 ms has elapsed from the beginning of the song. The FD reproducing apparatus 8a has a function of reading the MIDI data from the FD described above (that is, a function as a sequencer) and a timing adjusting function of synchronizing the reading operation with the reproduction of the time-series audio data by the CD driving apparatus 1. Have The configuration of the FD reproducing device 8a having various functions will be described below with reference to FIG.

FIG. 11 is a block diagram for explaining the configuration of the control circuit provided in the FD reproducing device 8a. The control circuit shown in FIG. 11 has a function as a sequencer and a timing adjusting function.

The event buffer 302 is a buffer for storing the events read from the FD. here,
It is possible that one delta time is followed by two or more consecutive events. In such a case, all consecutive events are read from the FD and the event buffer 30
Stored in 2. Delta time register 303 is FD
It is a register that stores the delta time read from the. As described above, this delta time specifies the elapsed time between two events that are adjacent to each other.

The adder 311 and the register 312 form an accumulator. This accumulator obtains the accumulated value of a series of delta times which are sequentially read from the FD and stored in the register 303. More specifically, the accumulated value of the delta time at the present time is stored in the register 312.
To be held by. Also, adder 3
11 adds the accumulated value stored in the register 312 and the delta time stored in the register 303, and outputs the addition result M. This M is a numerical value corresponding to the target time for transferring one or a plurality of events stored in the event buffer 302 to the controller 3. Therefore, in the following, this M is called target time data. When the time designated by the target time data M arrives, the event transfer control means 330 causes the registers 303 and 312 to end.
The write clock is supplied to. As a result, the adder 3
11 output data, that is, register 312 till then
A value obtained by adding the accumulated value stored in the register and the delta time stored in the register 303 is stored in the register 312 as a new accumulated value. The new delta time read from the FD at this time is stored in the register 303. The event transfer control means 330 will be described later.

The adder 321 and the register 322 constitute an accumulator that accumulates "+1" each time the tempo clock CT 'is given from the clock generating means 210. The adder 321 adds the data stored in the register 322 and the fixed value “+1” and outputs the result. Register 322
Is written with an initial value "0" when reproduction of MIDI data from the FD is started. After that, the register 32
Each time the tempo clock CT ′ is given, the output data of the adder 321, that is, the addition result of the data stored in the register 322 and “+1” at that time is written in 2. The output data N ′ of this register 322 is
It is used as elapsed time data representing the elapsed time since the start of reproduction of MIDI data.

When the elapsed time data N ′ reaches the target time data M, the event transfer control means 330 sends to the controller 3 a transfer instruction to read and capture one or more events in the event buffer 302. Further, at this time, the event transfer control means 330 supplies the write clock to the registers 303 and 312 as described above.

The timing adjusting means 341 is a circuit for adjusting the timing for synchronizing the output operation of the MIDI data event to the controller 3 with the reproduction of the time series audio data from the CD. More specifically, when a time code larger than “0” is given from the controller 3, the timing adjusting means 341 sets the time code as the first reproduction time data TCD ′, and further changes it to the elapsed time data N ′ at that time. Multiply the period τ of the tempo clock CT and from the multiplication result, 500 ms
ec is subtracted, and the second reproduction time data TFD '= N *
Calculate τ-500 msec. This second reproduction time data TFD 'indicates the elapsed time from when the automatic piano starts playing the music to the present time, that is, how many seconds after the beginning of the music the currently playing part is. It represents.

Then, the timing adjusting means 341 compares these reproduction time data TCD 'and TFD',
The following processing is performed based on the comparison result. a. When the difference between TCD ′ and TFD ′ falls within a predetermined allowable range In this case, the timing adjusting means 341 does nothing.

B. When TCD '>TFD' and the difference between the two exceeds the allowable range In this case, the part in the music currently being played by the event read from the FD is sung or played by reproduction from the CD. Time difference TCD'-
It can be said that it is a place delayed by TFD '. Therefore, the timing adjusting means 341 divides the time difference TCD'-TFD 'by the period τ' of the tempo clock CT ', and the division result (TCD'-TFD') / τ 'is registered in the register 30.
3 is subtracted from the delta time, and the delta time after the subtraction is written in the register 303. The delta time after this subtraction is controlled so as to always take a positive value. That is, when the division result (TCD-TFD) / τ is large,
The result of division from the delta time in the register 303 (TCD
If −TFD) / τ is subtracted as it is, the delta time after the subtraction becomes a negative value. Therefore, the division result (TCD-TF) is calculated from the delta time in the register 303.
When the result of subtracting D) / τ (that is, the delta time after subtraction) has a negative value, for example, the division result (TCD-TFD) so that the delta time can have a positive value.
/ Τ is divided into two, and one of the divided results (TCD-T
FD) / (τ * 2) at that time in the register 303
The delta time stored in the register 303 is subtracted from the delta time, and the remaining division result (TCD-TFD) / (τ * 2) is subtracted from the subsequent delta time stored in the register 303. By executing such processing, the delta time value is always a positive value. Thus, the division result (TCD-TFD) / τ is large, and the division result (TCD-TFD) is subtracted from the delta time in the register 303.
If D) / τ is subtracted as it is and the delta time after subtraction becomes a negative value, it can be divided into multiple times (that is, by changing the values of a plurality of consecutive delta times as appropriate). ) It is sufficient to absorb the generated deviation. As a result, for a while, the automatic performance based on the event reading from the FD and the singing or performance based on the data reading from the CD are kept in a synchronized state.

C. When TCD '<TFD' and the difference between the two exceeds the allowable range In this case, the part in the music currently played by the event read from the FD is sung or played by reproduction from the CD. Time difference TFD'-
It can be said that this is a place advanced by TCD '. Therefore, the timing adjusting means 341 divides the time difference TFD'-TCD 'by the period τ' of the tempo clock CT ', and the division result (TFD'-TCD') / τ 'is registered in the register 30.
3 is added to the delta time, and the added delta time is written in the register 303. The above is the details of the musical sound reproduction / recording apparatus 700 according to the present embodiment. Hereinafter, the operation of the musical sound reproduction / recording device 700 will be described in detail with reference to FIG.

FIG. 12 is a time chart showing the operation of the musical sound reproduction / recording apparatus according to this embodiment. More specifically, in FIG. 12, a time code read from a CD, audio data read from a CD, D
The audio data output from SP2, the MIDI data read from FD, and the sound generated from the piano 11 are shown in time series. In FIG. 12,
a [k] (k = 0, 0.25, 0.5, ...) is audio data of a portion within a section from k seconds to k + 1 seconds when the start time of the music is 0 seconds. Also, m [k]
(K = 0, 0.25, 0.5, ...) Is MIDI data used for performance control of a portion within a section from k seconds to k + 1 seconds when the start time of the music is 0 seconds. Also,
In the example shown in FIG. 12, the time code is reproduced from the CD every 250 msec. In addition, the following description is based on MIDI.
Data m [1.0], m [1.5], m [2.0] are
The clocking time r [1.0] by the clocking means 220,
MID generated at r [1.5] and r [2.0]
It is assumed that the MIDI data includes an I event (see FIG. 7).

When an automatic performance is performed using the drive solenoid group 17 and the piano 11, the controller 3 uses the FD
A playback instruction for MIDI data is sent to the playback device 8a. FD
Upon receiving the playback instruction from the controller 3, the playback device 8a immediately starts the operation of reading MIDI data from the FD. As a result, the MIDI data m [0], m
[1.0], to are sequentially read from the FD, and the event in the MIDI data is transferred to the controller 3. In this operation, the transfer timing of the event in the MIDI data is controlled based on the delta time in the MIDI data. The control of the transfer timing based on the delta time is as described above.

Here, at the beginning of the reproduction of the MIDI data, since the reproduction of the audio data from the CD has not been started, the time code is not supplied to the FD reproducing device 8a. Therefore, in the FD reproducing device 8a, the delta time in the register 303 is not adjusted by the timing adjusting means 341.

250 ms after starting playback of MIDI data
When ec elapses, an event instructing the start of reproduction of the CD is read from the FD. In response to this event, the controller 3 sends a reproduction instruction to the CD drive device 1. As a result, the audio data a [0] and the time code “0” at the beginning of the music are read from the CD. Then, when 250 msec has further elapsed, the audio data a [0] and the time code “0” are output from the DSP 2 to the controller 3. The DSP 2 determines the type of data reproduced from the CD, whether the CD is normal, etc. by using the time of 250 msec in which the audio data a [0] is delayed, and the determination result Is notified to the controller 3. In this case, the controller 3 receives a notification that the music data reproduced from the CD is time-series audio data and does not include MIDI data and that the CD is normal.

The time code “0” output together with the audio data a [0] from the DSP 2 is sent to the FD reproducing device 8a via the controller 3. But FD
The timing adjusting means 341 in the reproducing apparatus 8a does not adjust the delta time using the time code "0". After that, when 250 msec has elapsed, the DSP 2 outputs the time code "0.25". At this time, the timing adjusting means 341 adjusts the above-mentioned delta time because the time code larger than "0" is supplied. Then, thereafter, each time the time code is supplied from the DSP 2, the above-mentioned delta time is adjusted.

250 ms after the CD playback instruction is issued
When ec elapses, a song or performance corresponding to the audio data and an automatic performance corresponding to the MIDI data are simultaneously started. Then, when 250 msec has further elapsed, the timing adjustment by the timing adjusting means 341 is started. Therefore, the audio data a [k]
Of the MIDI data and the MIDI data m [k], 250ms from the beginning of the music is reproduced as a sound in a state where the synchronization is maintained.
ec after that, that is, a [0.
25] and subsequent audio data and m [0.25] and subsequent MIDI data. As a result, the timing means 2 described above
Time measured by 20 r [1.0], r [1.5], r
MIDI data m [1.0], m [1.5], m [2.
0] and corresponding audio data a [1.0], a
[1.5] and a [2.0] are reproduced as sounds while maintaining synchronization.

As is clear from the above description, according to the musical sound reproducing / recording apparatus 700 of this embodiment, MIDI data is recorded in synchronization with the reproduction of the CD, and the recorded MIDI data is recorded on the corresponding CD. The stored music data can be reproduced in synchronization.
