Description

[Detailed Description of the Invention] The present invention relates to a display device for a programmable rhythm machine, and its feature is that the timing of generating the sounds of all sound sources in a predetermined bar is displayed simultaneously for each sound source. By doing so, it is possible to see at a glance the timing at which each sound source generates the sound, which makes it easy to set the timing and eliminates the risk of setting mistakes.

Figure 1 shows the display 1 and timing input switch 2 of a conventionally known programmable rhythm machine. An input switch 2 is provided, and when the timing for generating a sound from a particular sound source selected by a sound source changeover switch (not shown) is set using the timing input switch 2, the built-in It is stored in the microcomputer and displayed on the LED of the display 1, and the timings for all sound sources are set by switching the sound source changeover switch.

However, in such a device, what is displayed on the display 1 is only about the sound source currently selected by the sound source changeover switch, so the relative timing with other sound sources may vary. It was difficult to understand and there was a risk of making a mistake in setting the timing.

The object of the present invention is to improve the above-mentioned drawbacks of the conventional device, and to provide an indicator for a programmable rhythm machine that allows at a glance the mutual timing of generating sounds of all sound sources.

Embodiments of the invention will be described with reference to the drawings.

FIG. 2 shows the display 10 and timing input switch 2.
Also, FIG. 3 shows a block diagram of the control device.

A grid pattern is drawn on the surface of the display device 10, and display elements such as LEDs, liquid crystal display elements, fluorescent display tubes, etc. are provided at all the intersections of the grid pattern.1. The horizontal lines of the grid correspond to the sound sources marked on the left end, and the vertical lines correspond to the 16 timing input switches 2 provided below.

The accent timing of the entire sound source is displayed on the uppermost horizontal line, and the accent timing of the entire sound source is displayed below.
. . . etc. The timing at which one measure of sound is generated for all the sound sources that can be created by the programmable rhythm machine is displayed by lighting.

The display control circuit 3 that lights up the display elements of the display panel 10 is operated by the sound source control circuit 5 that drives and controls the sound source circuit 4, and is operated based on the signals stored in the memory 6 during performance, and based on the signals stored in the memory 6 when setting the timing. The timing input switch 2 and the sound source changeover switch 8 for each sound source are also operated based on signals input through the input control circuit 7.

Next, its operation will be explained.

To set the timing, switch the mode changeover switch 9 to the setting mode, select a specific sound source with the sound source changeover switch 8, and generate a sound with the timing input switch 2. Change the timing (for example, 1.
5.9.13), the contents are displayed by lighting on the display 10 and stored in the memory 6 at the same time.

Next, switch the sound source changeover switch 8 to another sound source,
The timing is set while comparing it with the display of the previously set timing, and after setting the sound generation timing for all the sound sources one after another, the mode changeover switch 9 is switched to the performance mode.

During performance, the sound source circuit 4 is driven and controlled based on the signals stored in the memory 6, and the timing at which the sound is generated is simultaneously displayed on the display 10 for all sound sources.

As explained above, the display device of the programmable rhythm machine of the present invention is designed to simultaneously display the timing of tone generation of all sound sources in a predetermined measure on each sound source side. The timing of mutual sound generation can be seen at a glance, the timing can be easily set, and there is no risk of setting mistakes.

In addition, in the case of a song where the rhythm changes midway through, it is possible to set two (or more) timings for each sound source, and in that case, the timing will be displayed at the measure where the rhythm changes. Needless to say, it should also be changed.
