Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an automatic rhythm performance device that allows a player to freely create rhythm patterns.

The applicant previously discovered that in a conventional automatic rhythm performance device,
The rhythm pattern is pre-programmed, so when playing this, you can select a specific rhythm such as a waltz or mambo from among the rhythms of the pre-programmed pattern, or play several rhythms. I used to select rhythms and play them in combination, but since the rhythm pattern was fixed, there was little variation in the performance.
In order to correct the problem that performers are unable to perform interestingly due to their limited expressiveness, we have developed a system that allows performers to freely create their own preferred rhythm patterns, which is completely different from conventional automatic rhythm performance devices. We have filed an application for an automatic rhythm performance device that can generate rhythms.

(Application filed on November 1, 1972) However, although the automatic rhythm playing device filed above has the advantage of being able to freely create rhythm patterns that the performer prefers, it requires that a sound source be connected to each pattern forming device. As a result, a new drawback arose: the need to increase the size of the device when creating complex rhythms.

The present invention provides a sound source selection switch between the pattern forming device and the sound source, and allows the pattern forming device to be used with several types of sound sources, thereby reducing the size of the entire device and creating complex rhythms. The present invention provides an automatic rhythm performance device that can perform the following functions.

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

Reference numeral 1 denotes a clock pulse oscillator, which is connected to a tempo regulating volume 2 and a start switch 3, and when the start switch 3 is turned on, clock pulses are generated at a frequency appropriately controlled by the tempo regulating volume 2. The sequential pulse generator 4 connected to the clock pulse oscillator 1 generates 32 clock pulses, which are provided at the output end of the sequential pulse generator 4 and displayed on the illustrated address indicators LE1 to LE32. Assume that pulses are sequentially output to the terminals of .

In this case, the start switch 3 controls the oscillation and stopping of the clock pulses oscillated by the clock pulse oscillator 1, and sequentially resets the pulse generator 4 so that the pulses are output in sequence starting from the first beat (first terminal). .

The sequential pulse generator 4 includes the address display LE1.
~ Connect the pattern forming devices (V1 to Vn and sound source selection switches VS1 to VSn) via LE32.

Regarding the pattern forming devices v1 to Vn, taking the pattern forming device ① as an example, the touch switch T
When a hand touches any of the touch antennas 101 to 132 of the PO, the gate circuits TG101 to TG132 are opened by successive pulses from the pulse generator 4, and are made conductive. A tactile antenna is connected to a touch switch TPG1, which generates a pulse.

The ungate circuits AG101 to AG132 are connected to the sequential pulses generated by the pulse generator 4 and the touch switch TPO.
, and are outputted only when the pulses generated in .

The other ungated circuit MGIOI to MG132 is
The sequential pulses from the sequential pulse generator 4 are passed only when the memory circuits M101 to M132 are storing data.

Thus, the performer can use any plurality of tactile antennas 101-1.
32, the signal becomes a pulse pattern signal programmed by sequential pulses passing through the AND gate circuits MG101 to MG132 of the address of the touched touch antenna, arrives at the sound source selection switch VS1, and is selected by the sound source selection switch vS1. The sound source 5 is driven, and the sound is emitted through an amplifier 6 and a speaker 7.

The memory display lamps ML101 to ML132 are lit by the outputs of the memory circuits M101 to M132, and display the address touched by the touch antennas 101 to 132.

Reset switch RS1 connects memory circuits M101 to M132
This is to erase the memory state of.

The gate circuit CG is a circuit that opens and closes every half period of the clock pulse, and in one pattern forming device 1, the tactile antennas 101 to 1 are simultaneously applied to a plurality of consecutive addresses.
In order to generate a pulse from the touch switch TPG1 even if the touch switch TPG1 is touched, the touch input is always erased in the second half of one clock pulse, and the touch switch TPG1 is
This puts PG1 into a reset state.

Note that the number of output terminals of the sequential pulse generator 4 is not limited.

The sound source selection switches ■S1 to VSn are as shown in the figure.
Multi-contact VG1 to VGn switch, for example, contact VG1
is connected to the bass drum Bd of the sound source 5, contact ■G2 is connected to the snare drum Sd of the sound source 5, contact ■G3 is connected to the sound source 5 (D cymbal Cy, and contact VGn is connected to the bongo Bo of the sound source 5, respectively.

Now, when playing a waltz by driving the bass drum Bd, snare drum Sd, and cymbal Cy of sound source 5, set the sound source selection switch S1 of pattern forming device ■1 to contact VG1, and set the sound source selection switch of pattern forming device ■2. ■S2 is connected to contact ■G2, sound source selection switch ■S3 of pattern forming device ■3 is connected to contact ■G3, and touch antennas 101 to 13 of each pattern forming device v1, ■2, ■3 are connected.
2,201 to 232, and 301 to 332 to form a pulse pattern signal, the pattern signal drives the bass drum Bd, snare drum Sd, and cymbal Cy of the sound source 5, and waltzes according to the rhythm pattern set by the performer. is emitted from speaker 7.

When changing the type of sound source 5, the sound source selection switch ■S1 to V can be changed without using any other pattern forming device.
By appropriately switching Sn and reprogramming the rhythm pattern signal, the sound is emitted using the changed sound source.

As described above, according to the present invention, the pattern forming device can be used for a number of sound sources by switching the sound source selection switch, so there is no need to create a pattern forming device for each type of sound source, and the entire device can be downsized.

Furthermore, when changing the type of sound source when the pulse pattern is the same, it is only necessary to change the sound source selection switch, and there is no need to recreate the pulse pattern using a pattern forming device, which saves time and makes the operation simple.
