Description

[Detailed Description of the Invention] The present invention relates to an automatic performance device for an electronic musical instrument, which enables automatic performance with a rich variety by recording and reproducing instrument operation Z including tone presets, rhythm sequence programs, etc. .

As a conventional automatic performance device for an electronic musical instrument, one is known that records and plays back instrument operation data corresponding to operations on a keyboard and panel surface controls, thereby transcribing musical instrument performance (for example, (Japanese Patent Application Laid-open No. 17213).

However, in this conventional device, data related to the tone tree set operation and/or rhythm sequence program operation is desired to be recorded as musical instrument operation data.
In reproducible musical instrument performance (i.e., automatic performance), the timbre,
I don't like the rhythm etc. becoming monotonous.

In addition, by simply applying this conventional device, you can set tone presets,
If an attempt is made to reproduce the manner in which musical tones are generated in response to operations such as a rhythm sequence program, there is a problem in that the amount of data to be recorded increases.

That is, if the same tone color series (or rhythm sequence) is selected several times during performance recording, the corresponding data must be recorded each time, which is not a good idea.

SUMMARY OF THE INVENTION An object of the present invention is to provide an improved automatic performance device for an electronic musical instrument that is capable of performing automatic performance with a wide variety of tones, rhythms, etc. with a small amount of recorded data.

The automatic performance device according to the present invention transfers specified operation data for a plurality of modes related to operations for specifying musical sound generation modes such as tone presets and rhythm sequence programs from a memory to a recording device for recording, and also allows the recording device to record which mode has been selected. The amount of selection operation data indicating the heat is recorded together with the key operation data, and during playback, the data for multiple modes is transferred from the recording device to the memory, and the specified operation data is read out from the memory according to the selection operation data from the recording device. Keyboard performance and musical sound generation mode are reproduced based on designated operation data and key operation data from a recording device.

It is designed to control musical tone generation operations including playback.

The storage device [46 includes a tone color preset memo IJ 46A and a rhythm sequence program memory 46BY.

As shown in FIG. 2, the tone preset memory 46A has four storage areas for storing each of the preset data PSDI to PSD4Y, and these storage areas can be addressed by the four preset selection operators 32. It looks like this.

Further, the rhythm sequence program memory 46B is
Sequence data 5QDI to 5QD4Y as shown in the figure
It has four storage areas, each for storing data.
These storage areas are each addressed by four sequence selection operators.

The external recording device 48 is a recording medium 50 such as a disk or tape.

It includes an autorhythm section that generates a rhythm sound signal based on the rhythm.

The key tone signal and rhythm tone signal from the tone forming circuit section are supplied to a speaker 66 via an output amplifier 64 and converted into sound.

Next, tone presets, rhythm sequence programs,
Each operation of normal performance, performance recording, and performance playback will be explained in sequence.

Tone preset 79 panel tone color specification operator row and effect specification operator 30
The preset memory command operator PM and one of the preset selection operators 32 are turned on at the same time under such setting conditions. In this case, for example, if the preset selection controller corresponding to Tone Reset PRI is turned on, the designated operation data corresponding to the setting state of the designated controller A and (9) at this time is the preset data shown in Figure 2. P
The data is written as SDI to the timbre 1 memory 46A.

Similarly, the memory 46A stores preset data PSD2 to PSD2 corresponding to tone presets PR2 to PR4.
PSD4"k can be written. Therefore, it is possible to preset four different key tone generation modes on the channel side. Rhythm sequence program 22 is appropriately set so as to have a desired rhythm sound generation mode, and under the above setting conditions, the sequence program control operator for commanding the load LD9 and one of the sequence selection operators are turned on at the same time. in this case,
- For example, by adding the specified operator, the rhythm type [March l'&
At the same time, use the specified operator n to perform in-measure returns "Pl", "B2", "B3", "B2", "B2", etc.
..., and turn on the selection control corresponding to the rhythm sequence M1, [March PtJ, [March P2J] as sequence data 5QDI in FIG.
, [March P3J, [March B2J, [March P2J・
. . . are written into the rhythm sequence program memory 46B in bar order.

Similarly, the memory 46B stores sequence data 5QD2-5 corresponding to the rhythm sequences M2-M4.
QD4Y can be written. Therefore, A! On the channel surface, four different rhythm sound generation modes can be programmed. The rhythm sequence program is described in detail in Japanese Patent Laid-Open No. 140894/1983.

Normally, the player performs the preset data PSDI by, for example, turning on one of the preset selection operators 32 (l').
.about.PSD4, and then the desired music piece can be played on the keyboard 10.

Now, if one of the preset selection operators 32 is turned on, for example, an operator corresponding to the timbre preset (PRI), the preset data PSDI will be output one after another from the timbre preset memory 46A, and will be stored in the buffer memory 62 as timbre control data. written to.

Further, each time there is a change in the key state of the keyboard 10, key data indicating the changed key is detected from the key switch circuit 12 and written into the buffer memory 58.

Therefore, the musical tone forming circuit 56 forms a key musical tone signal based on the key data from the buffer memory 58 and the tone control data from the buffer memory 62, and supplies it to the speaker 66 via the output amplifier 64. Therefore, the speaker 66
From then on, keyboard performance sounds are produced in the key tone generation mode indicated by the preset data PSDI.

After this, if you select a different set of data than the preset data PSDI, the keyboard performance sound will be produced in the key tone generation mode indicated by the selected preset data. Also, if the panel control transition operator PNL Y is turned on, the specified operation will be performed. The operation data corresponding to the operation of Koa and (Shi) is buffered as tone control data! j62, and the timbre and effects of the keyboard performance sound are controlled accordingly. That is, in this case, a desired tone or effect can be specified by manually operating the specified operator row and 38 as appropriate.

Note that if any of the preset selection operators 32 is subsequently turned on, the channel control transition operator PNL is automatically turned off, making it possible to control the key tone based on the selected preset data. In this case, since the operating states of the designated controls and the levers on the novell surface do not match the operating states indicated by the selected preset data, a situation arises in which the preset states are unknown to the performer. In order to prevent such an abnormal situation from occurring, the designated operator row and 30 may be moved by a drive means such as a motor in accordance with the selected preset data, so that the preset state can be seen at a glance.

By the way, regarding autorhythm performance, see.

There are cases where Kunsu data is not used and cases where it is used.

First, if you do not use sequence data, play FL
Without turning on the operator corresponding to Y and the sequence selection operator 24, select the rhythm type specifying operator row and J? Turn on the turn designation operators n and l one by one. For example, specify ``1 waltz'' with the specified operator string and rptJ with the specified operator η.
When 'Y' is specified, rhythm pattern data corresponding to one waltz PIJ is read out from the rhythm nozzle turn memory 44 in accordance with a tempo signal (not shown), and written into the buffer memory mark as rhythm control data. For this reason, the rhythm sound forming circuit 56 forms a rhythm sound signal based on the rhythm control data from the buffer memory (4) and supplies it to the speaker 66 via the output amplifier 64yIl-.

Therefore, the waltz rhythm sound is repeatedly produced from the speaker section according to the turn r PIJ.

Also, when using sequence data, play FL
The operator corresponding to Y and one of the sequence selection operator controls are turned on at the same time. For example rhythm sequence M
When the selection operator corresponding to 1 is turned on, sequence data 5QDI is read out for each bar, and a rhythm pattern is specified for each bar accordingly. That is, from the rhythm pattern memory 44, the number specified by the sequence data SQDI is stored for each measure. The turn data is read out in accordance with the tempo signal and written into the buffer memory mark as rhythm control data. Therefore, the autorhythm sound is required from the speaker 66 in the rhythm sound generation mode indicated by the sequence data 5QDI. Since the pattern of the autorhythm sound in this case can be changed for each measure, it is possible to create a very wide variety of sounds, unlike the case of using the sequence data tone described above. Note that the O) IJ rhythm is usually started before the above-mentioned keyboard performance begins.

When the recording mode is designated by switch operation in the recording/playback control switch circuit 54, the preset data PSDI to PSD4 of the tone color preset memory 46A and the sequence data 5QDI to 8QD4 of the rhythm sequence program memory 46B are transferred via the buffer circuit 52. The data is transferred to the external recording device 48 and recorded on the recording medium 50 in the format shown in FIG. That is, preset data PSD (PSDI to PSD4) from memory 46A is recorded at the beginning of the recording medium (material), and then sequence data 5QD (SQ) from memory 46B is recorded.
DI~5QD4) is recorded.

After this, no? When you start operating the panel panel and keyboard, the 17 rhythm tones and keyboard performance sounds can be used as in the case of normal performance described above, while the instrument operation data corresponding to the panel panel and keyboard operations can be used. As shown in Figure 4, following the sequence data SQD, it is written between the recording media @
? It will be done.

That is, assuming that the musical instrument operation begins with an autorhythm start operation and uses sequence data to generate an autorhythm sound, one of the operators corresponding to play FLY and one of the sequence selection operators (for example, the rhythm sequence Ml (control corresponding to ) are turned on at the same time.

When the CPU 38 detects the change in the operator state at this time, it generates time data Δ indicating the relative time up to the time when this change is detected.
Tl and operator data 0PRI indicating the sequence selection operator whose state has changed are formed and stored in the external recording device 48.
supply to. For this reason, there is a gap between recording media as shown in Figure 4 (1
5) As shown, time data ΔTl and operator data 0PRI
are recorded sequentially.

Next, when one preset selection control 320 (for example, the control corresponding to tone color setting PRI) is turned on, time data ΔT2 indicating the relative time from the previous control change to the current control change is displayed, as described above. Control data 0 indicating the preset selection control whose state changed
PR2 are sequentially recorded between the recording media.

After this, when the performance Z starts on the keyboard 10, the first key state change is detected based on the first key press operation, and the time indicating the relative time from the previous operator change to the first key state change is detected accordingly. The data ΔT3 and the key data KEY indicating the changed key are sequentially recorded on the recording medium.

Thereafter, time data and key data are similarly recorded on the recording medium every time a key state change is detected.

In the process of playing the keyboard, the first operator group 1
6, you can select a rhythm sequence different from the previous one, or specify the rhythm type and pattern without using extra sequence data (16), but the time data and operator data corresponding to these operations are also recorded in the same way as above. In addition, with the second control group 18, it is possible to select a different tone than before, switch to panel control, and manually specify the tone and effect, and the time data and operations corresponding to these operations. Child data is also recorded in the same manner as above.

When the performance recording is completed, the recording medium 50 can be taken out from the external recording device 48, and can be used in another automatic performance device of the same type as that of this embodiment to reproduce the musical instrument performance.

Performance Reproduction When the recording medium 50 on which the musical instrument performance has been recorded as described above is inserted into a predetermined receiving slot of the external recording device ft48 and the playback mode is specified by operating a switch in the recording/playback control switch circuit 54, the recording starts. Preset data PSD and sequence data SQD between the media are transferred to tone color preset memo IJ 46A and rhythm sequence program memory 46B, respectively.

Then, the CPU 38 reads the time data ΔTl and the operator data 0PRIY from the recording medium group as the first musical instrument operation data to the working area 40, measures the time corresponding to the time data ΔT1 according to a tempo signal (not shown), and calculates the time at this time. When the data reaches the controller data 0PRI, the data is read from the storage device [46].

Here, assuming that the operator data 0PRI indicates the operator corresponding to the rhythm sequence Ml as in the recording example described above, the sequence data 5QDI is read out for each measure from the rhythm sequence program memo I) 46B, and The pattern data specified by the sequence data 5QDI is read out from the rhythm turn memory 44 for each bar in accordance with the tempo signal. Then, the read not turn data is stored in the buffer memory (
(b), so the speaker unit uses the autorhythm sound in the rhythm sound generation mode indicated by the sequence data 5QDI. As a result, the manner in which rhythm sounds are generated during recording is reproduced.

After this, time data ΔT2 and operator data 0PR2
is read out to the working area 40, and the time data ΔT2
The time corresponding to is measured. When this time is reached, data is successively outputted from the storage device [46] in accordance with the operator data 0PR2.

Here, assuming that the controller data 0PR2 indicates the controller corresponding to the tone color PRI as in the recording example described above, the preset data PSDI is read from the tone color preset memory 46A and stored in the buffer memory 62 as tone color control data. written.

After this, time data ΔT3 is stored in the working area 40.
and key data KEY are read out, and time data ΔT
After time measurement based on 3, the key data KEY is written into the buffer memory 53. Therefore, the musical tone forming circuit unit forms the first key musical tone signal based on the tone control data from the buffer memory 62 and the key data from the buffer memory 58, and in response, the first keyboard performance sound is output from the speaker 66. It is required in the key tone generation mode indicated by the preset data PSDI.

The second and subsequent keyboard performance sounds are also reproduced in the same manner as described above. As a result, the keyboard performance and key tone generation mode at the time of recording will be reproduced.

Add the rhythm type designation operator from the recording medium (source), A
When the operation data corresponding to the operation of the turn designation operator ρ, the tone color designation operator Numa, the effect designation operator (equipment), etc. is read out, the data is not read out from the storage device 46.

That is, in this case, if the read operation data is related to rhythm, it is written to the buffer memory ω as rhythm control data, and if it is related to timbre/effect, it is written to the buffer memory 62 as timbre control data. . As a result, regardless of the tone preset or rhythm sequence, the keyboard performance sound is
．． It will be played according to the setting status of 22% field, (fund), etc.

As described above, according to the present invention, since data relating to operations for specifying musical sound generation modes such as tone color presets and rhythm sequence programs are recorded and reproduced, it is possible to perform automatic performances with a wide variety of variations.

1. The data related to the musical sound generation mode selection operation is processed separately from the data related to the musical sound generation mode specification operation, and the data is read from the memory according to the latter data during playback. No matter how many times a tone color preset (or rhythm sequence) is selected, the corresponding preset data (or sequence data) only needs to be recorded once, which has the effect of reducing the amount of data recorded.

Furthermore, since the data related to the musical sound generation mode specification operation is transferred from the memory to the recording device, even if the data in the memory is erased or rewritten by someone else operating the instrument, the musical instrument performance can be ensured based on the recorded data. It has the advantage of being reproducible.
