Description

[Detailed Description of the Invention] The present invention is an automatic system that allows a performer to freely create the rhythm pattern that he or she wants to play, and also allows the rhythm pattern setting status to be easily recognized by lighting a lamp. The present invention relates to a rhythm performance device.

Previously, the applicant developed a conventional automatic rhythm performance device in order to correct the drawback that the rhythm pattern is fixed in the conventional automatic rhythm performance device, so there is no change in performance, and it is not possible to perform interestingly. We have filed an application for an automatic rhythm performance device that is completely different from a performance device and allows the performer to freely create rhythm patterns.

(Application filed on November 1, 1970) However, although the automatic rhythm performance device filed above is capable of freely creating the rhythm pattern it desires,
There is no display to check the rhythm pattern that you have set, so you have to actually listen to the sound, check it, and make corrections.

In order to eliminate these drawbacks, the present invention has been developed by lighting up a memory display lamp by touching the tactile antenna of a touch switch when creating a rhythm pattern, and by visually forming the rhythm pattern that the user desires. This eliminates forgetting to touch the touch antenna and erroneous operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be specifically described below with reference to the drawings showing one embodiment.

1 is a performance clock pulse oscillator;
A tempo regulating volume 2 and a start switch 3 are connected to the tempo regulating volume 2 and a start switch 3, and a pulse generator 4 is sequentially connected to the start switch 3.

The clock pulse oscillator 1 oscillates clock pulses at a frequency suitably controlled by the tempo regulating volume 2, and when the start switch 3 is turned on, supplies the clock pulses to the sequential pulse generator 4 in the next stage. The sequential pulse generator 4 sequentially outputs pulses to 32 terminals provided at the output end of the sequential pulse generator 4 and displayed on the illustrated address display devices LE1 to LE32. .

In this case, the start switch 3 controls the oscillation and stopping of the clock pulses oscillated by the clock pulse oscillator 1, sequentially supplies and stops the clock pulses to the pulse generator 4, and sequentially resets the pulse generator 4, ensuring that the first beat ( The pulses are output sequentially from the first terminal).

The sequential pulse generator 4 includes the address display LE1.
- Pattern forming device for various sound sources via LE32 ■1
〜Vn, and then the pattern forming device ■1〜Vn
There are as many sound sources as necessary, such as bass drums and cymbals.

Taking the pattern forming device V1 as an example, the pattern forming devices ① to Vn include a sound source VG and a touch switch TPG.
1. Touch antenna 101 of the touch switch TPG1~
132, memory display lamp ML101-ML132,
Gate circuit TGI01-TG132, CG1, AND gate circuit AG101-AG132, MGI01-MG1
32 and the reset switch RS1, and the other pattern forming devices 2 to Vn are formed in the same manner.

Tactile antennas 101 to 132 of touch switch TPG1
When you touch the hand and sequential pulses from the pulse generator 4 arrive at the gate circuits TG101 to TG132, the gate circuits are opened and the touch antenna connected to the touch switch TPG1 is connected to the touch switch TPG1 by the touch input. TPG1 generates a pulse, and gate circuit AG
101 to AG132 are output only when the sequential pulses generated by the sequential pulse generator 4 and the pulses generated by the touch switch TPG1 arrive at the same time, and the memory circuits M101 to M132 are operated by this output.

On the other hand, the AND gate circuits M0101 to MG132 sequentially pass the pulses from the pulse generator 4 only when the memory circuits M101 to M132 have stored the sound source V.
It is assumed that the configuration is such that the signal is input to G1 and then emitted through an amplifier 5 and a speaker 6.

Memory display lamps ML101 to ML132 are memory circuits M101 to M132 that are activated by touching the tactile antennas 101 to 132 of the touch switch TPG1.
It is turned on by the output of , and continues to be turned on while the memory circuits M101 to M132 are storing data.

Note that the reset switch RS1 is connected to the memory circuits M101 to M1.
This is for erasing the storage state of 32.

Incidentally, in this embodiment, the number of output terminals of the sequential pulse generator 4 is 32, but it goes without saying that the device of the present invention is not limited to this number of output terminals.

The gate circuit CG1 is a circuit that opens and closes every half cycle of the clock pulse, and even if touch antennas (for example, 101 and 102, or 102, 103, and 104) are touched at multiple consecutive addresses in one pattern forming device V1, , so that pulses are generated from the touch switch TPG1, so that the second half of one clock pulse always erases the touch input and puts the touch switch TPG1 in the reset state.

Now, a case will be described in which, for example, the sound source is emitted when a pulse arrives at the second address of the pattern forming device (1), that is, the address display LE2.

Turn on the start switch 3 and press the touch switch T.
When the tactile antenna 102 of PG1 is touched, pulses sequentially arrive at the address display LE2 while the hand is being touched.

When the pulses arrive one after another, the gate circuit TG101 opens, a contact input is felt by the touch switch TPG1, and a pulse is generated.

At this time, since the pulses have sequentially arrived at the AND gate circuit AG102, the AND gate circuit AG102 becomes conductive, and its output is input to and stored in the memory circuit M102, and at the same time, the memory display lamp ML102 lights up, and at the same time, the corresponding address The sequential pulses of the AND gate circuit MG
102, excites the sound source VG1, and is emitted through the amplifier 5 and speaker 6.

As described above, the present invention operates the memory circuit by the output of the touch switch generated by touching the tactile antenna of the touch switch, and the memory display lamp is lit by the output of the memory circuit. In order to create a rhythm pattern, the performer envisions the sound sources and the intervals between the sound sources that make up the rhythm, and when the player touches the appropriately selected tactile antenna, the memory display lamp will continue to light up due to the memory circuit. It is possible to prevent forgetting to touch the tactile antenna or touching it incorrectly, and it is possible to accurately create a desired rhythm pattern without visually checking it.

As shown in the figure, a high frequency clock pulse oscillator 7 which oscillates clock pulses of a higher frequency than the performance clock pulse oscillator 1 is connected to the start switch 3, and the high frequency clock pulse oscillator 7 is activated even when the start switch 3 is in the OFF state. A sequential pulse generator 4 connected to a start switch 3 is configured so that sequential pulses are sequentially delivered to the output terminal of the sequential pulse generator 4 at a sufficiently faster period than during performance.

Then, the memory circuits M101 to Mn32 are operated as described above by the high frequency sequential pulses, and the memory display lamps ML101 to MLn32 are lit by the output thereof, but the AND gate circuits M0101 to MGn32 have a higher frequency than the sequential pulses generated during performance. The high frequency sequential pulses are prevented from passing through, and when the start switch 3 is in the OFF state, the high frequency sequential pulses are prevented from reaching the sound sources VG1 to VGn.

This allows the performer to set the desired rhythm pattern while visually checking the memory display lamp before starting the performance, and by turning on the start switch, the set rhythm pattern can be set immediately. It has the effect of being able to perform rhythmic performances using patterns.
