Reference numeral 4 in FIG. 2 denotes a memory in which a plurality of musical tone data consisting of pitch data and tone length data is stored as performance information, and an address section that is incremented under the control of a CPU (central processing unit) 5. Based on the specified addresses from 6 onwards, musical tone data two tones ahead from the musical tone currently being played are sequentially read out.

Of the musical tone data that has been read out, the musical tone data that is one note ahead is set by the CPU 5 to the Y register 7tl, and the musical tone data that is two tones ahead is similarly set by the CPU 5G to the register 2 7C, and for each pressed needle, the musical tone data that is one tone ahead is set in the Y register 7tl. The musical tone data inside is C! PU5 transfers the musical tone data to the X register 7a, the musical tone data in the 2nd register 7C is transferred to the Y register 7b by the 0PU5, the next new musical tone data is read from the memory 4, and the musical tone data in the 2nd register 7C is read out by the 0PU5.
As a result, the X register 7a contains the musical tone data related to the currently pressed key, the Y register 7b contains the musical tone data to be played next, and the 2nd register 7C contains the musical tone data to be played next. Each data is always set.

Among the musical tone data in each of these X, Y, and Z registers 7a17bs7C, the pitch data is respectively given to the display drive section 8, and each LED of the rod 2 according to this pitch data is
3a to 3C are lit.

Further, the pitch data from the Y register 7b is given to the pitch-base section 9, and the pitch-base section 9 is provided with the operating knob l12 of the keyboard 1.
Pitch data corresponding to the key 2 is also given via the CPU 5, and a match is determined between the key 2 to be operated next and the key 2 currently being operated. This match signal from the pitch-base section 9 is given to the 3PU5, and in addition to transferring musical tone data to the X register 7a and Y register 7b and setting musical tone data to the 2nd register 7C, it is also used to drive the display. A start signal is applied to the ON terminal of the section 8 and the counting section 10.

In the counting section 10, time counting is started by applying a start signal, and the count data is calculated as follows: tone length - width section 1
1 is given. The note length data from the X register 7a is also given to the note length section 11, and a match is determined as to whether or not the operation time of the currently pressed key 2, that is, the time count data, is equal to the note length data. . This note length - Shikibe 1
The coincidence signal from 1 is given to the off terminal of the display drive unit 8, and the display drive unit 8 turns off the lighting of the yellow LED 3a of the key 2 according to the pitch data from the X register 7a from the start signal applied to the on terminal. The lighting time is made to match the tone length as the time until the matching signal is applied to the terminal.

Next, the operation of this embodiment will be explained based on the flowchart of FIG. 3, taking as an example the case of playing the 7F, t, melody shown in FIG.

It is assumed that performance information of the melody shown in FIG. 4 is currently stored in the memory 4. First, when the power switch is turned on, the CPU 5 increments the address section 6 to 011, and first reads out the musical tone data for two tones at the first address and the next address in the memory 4.
The musical tone data of the first note, which consists of the pitch data of "E" (C major scale) and the pitch data of the dotted quarter note, is stored in the Y register 7b.
Step S2), the next address's
-"Set the musical sound data of the second note, which consists of pitch data (the point above C represents C one octave higher) and eighth note length data, in the 2nd register 7C (step S3)0 Then, the pitch data of "Mi" among the musical tone data set in the Y register 7b is given to the display drive section 8, and the red LED 3b of the key 2 corresponding to this pitch data "Mi" is lit. At the same time, the pitch data of "r" among the musical tone data set in the 2nd register 7c is also given to the display drive section 8, and the green LED 3c of the key 2 corresponding to this pitch data r7 is lit, giving a reward. The display state of the unit 3 becomes as shown in FIG. 5(A) (step S4), and the display state waits for a key operation (step S,).

In this way, in steps 81 to S4, an initial state is displayed in which the key 2 to be operated is specified for the first first note and the next second note.

Then, when the performer operates the "Mi" key 2 on which the red LED 3b is lit, a key code based on this "Mi" key operation is given to the CPU 5, and as a result, the CPU 5 adjusts the pitch according to the key code. Give the data “mi” to pitch-shikibe 9. Pitch - The first part from Y register 7b is placed in the bottom part 9.
Since the pitch data for the note "Mi" is given, this pitch - Shikibe 9 to C! A match signal is given to PU5. Then, the 0PU5 determines that the next operation to be performed is in the section 2 (step S5), and the cylinder 1 in the Y register 7b is
The musical tone data of the note is transferred to the X register 7a, the musical tone data of the second note in the 2nd register 7C is transferred to the Y register 7b (step 86), and the address part 6 is incremented by 1 (step S7), and the third note is transferred from the memory 4. Pitch of sound
The musical tone data with the note length "U" and the note length of 14th note are read out and set in the second register 7C (step S8), and at the same time, a start signal is given to the display driving section 8 and the counting section 10.

Then, the yellow LED 3IIL of the key 2 corresponding to the pitch data "Mi" of the first note set in the The red LED 3b of key 2 corresponding to the high data "C" is also lit, and the green LED 3c of Ken 2 corresponding to the pitch data "U" of the third note set in the 2nd register 7c is also lit. (step S,), and as a result, as shown in FIG.
The lighting display for Mi's house 2 changes from red LED 3b to yellow L E D
3 To a, key 2 for the second note ri is lit in green I,
Switching from ED3Q to red LED3b, the third note “
The green LED 3c of the key 2 of "U" will newly light up.

In this way, the key 2 to be operated next for the currently pressed key 2 and the next key 2 to be operated are indicated by the red LEDs 3b and 1LE.
Instructions are given by D3c.

Then, the count data from the counting section 10, which starts time counting upon application of the start signal, is the tone length - the width section 1.
1, and the standby state is maintained as the tone length increases (step 51o), and the tone length section 11 has already been given the tone length data of the first tone from the X register 7a. When the time count data matches the note length data, a match signal is given from the note length section 11 to the display drive section 8, and the yellow LED 3a of the "Mi" pot is turned off.

In this way, the tone length of the currently pressed key 2 is indicated by the yellow LED 3a.

Next, it is determined whether the contents of the Y register 7b are an end code, that is, a code indicating that the melody following the final tone has ended (step 8u), and since the final tone has not been played yet, the process returns to step S. return. In this way, in steps S6 to S9, instructions are given for the next operation key and the next next operation button, and in step Slo, instructions are given for the note length of the key that is currently being pressed, and these operations are repeated when the new key is pressed. The process is repeated each time a key is detected (step S,), and as shown in (C), (D), (E), etc. in Figure 5, [the second note, third note, fourth note, . . , the transfer and setting between the registers 7a to 7C is performed, and the display state is sequentially switched.

When you start playing the fifth note "E", the next operation εP and the next operation key are both "G", so as shown in (F) in Figure 5, the "G" key 2 red LED 3b and green LED 3c
will light up, and the 6th note, ``When you start playing G-J, not only the note you are currently pressing, but also the next note and the next note will all be 'n', so (G) in Figure 5
All the LEDs 3a to 3C of the sea urchin bowl 2 will be lit.

Therefore, even if any of the keys in the current #key, the next operation key, and the next next operation key overlap, they are displayed separately.

When the state of (H) in Fig. 5 is reached and the performance begins before the 8th note, that is, a part of the final note, the musical tone data of the 8th note is stored in the X register 7a, and the final note is stored in the X register 7b. The musical tone data and the end code are set in the second register 7C, respectively, and the next operation key will not be specified as shown in FIG. 5(I). Then, when the final note is played, the end code has been set in the X register 7b, and the key pressing instruction ends (step S1).

In the above embodiment, the pitch-base part 9 detects the pressing of the next operation key and switches the display state, but the pitch-base part 9 is omitted and the pitch-base part 9 is used instead. The match signal from 11 may also be given to the CPU 5 to switch the display state.

In this way, even if there is a delay in pressing the next operation key, the key pressing instruction can be accurately performed at the same tempo regardless of this delay.

In addition, in the above embodiment, the key press instruction is up to the next operation key, but in order to be able to instruct the next operation key or even keys beyond that, registers 7a to 7C and display sections 3a to 3C are used.
may be increased.

Furthermore, although all instructions on the display unit 3 are given by lighting, some blinking displays may be incorporated and some LEDs may be omitted. In this case, if the LED to be lit and the LED to blink overlap, the LED may be left lit or the intensity may be changed.

In addition to LEDs, the display section 3 may use liquid crystal, electroluminescence, etc., or may be a line or surface light source instead of a point light source, or the entire key 2 may be illuminated. ~3C may be provided by 4 degrees, and in short, it is sufficient if the key 2 can be specified.

In addition, a counter section 10 that increments and a tone length-setting section 11 are used to indicate the tone length, but the tone length data is
Alternatively, the counter may be directly set from the register 7a and decremented, and a 0 signal may be applied to the off terminal of the display drive section.

〔Effect of the invention〕

As described above, the present invention not only instructs the length of the note to be pressed now and the pitch of the beo to be played next, but also instructs the key to be played next. Even when playing a long melody at a fast tempo, it becomes easier to grasp the flow of the song, fingering becomes easier, and as a result, smoother playing is possible, making it easier for beginners to play. It also has various effects, such as faster progress.

Furthermore, in order to notify the note length of the key after pressing the key,
