DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distributed chord output device for automatically outputting a dispersed chord to a chord inputted by simultaneously depressing a plurality of keys.

[0002]

2. Description of the Related Art In general, many keyboard instruments such as synthesizers have a function of repeatedly outputting a dispersed chord (arpeggio) and automatically outputting the same, a so-called arpeggiator function. For example, if you press the keys "do, mi, s, s" simultaneously on the keys arranged on the keyboard instrument, the chord "do, mi, s, s" is normally output, but the arpeggiator function is selected. If you do, at regular intervals,
Each single sound of "mi", "so", and "shi" is output while sequentially repeating. That is, the melody as shown in FIG. 5 is continuously output.

In FIG. 5, the output pattern of the arpeggio is set so as to be switched in ascending order, that is, sequentially from a low pitch to a high pitch. On the contrary, the output pattern may be set in a descending order or in a random order. Can also be set.
In other words, in the case of descending order, the output is performed in the order of shi, so, mi, and do.
It is also possible to output the arpeggio in the order of S, M, C, etc.

[0004]

However, in the above-described conventional distributed chord output device, although the output order of arpeggios can be changed, only a single tone can be output, and a double tone (2 It was not possible to set the above-mentioned synthesized sound composed of single tones) and chords (the chords themselves which were depressed). Therefore, there has been a demand for an invention of a distributed chord output device in which the output pattern can be set in a narrow range and a wider output pattern can be set.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a distributed chord output device capable of setting not only a single tone but also a double tone in an output pattern. To provide.

[0006]

According to a first aspect of the present invention, there is provided a distributed chord output device capable of dispersing and outputting a chord with respect to a depressed chord input. For each of the steps assigned in chronological order, it has a pattern memory for storing single tone information or multiple tone information of each pitch constituting the key pressed chord, and the single tone and multiple tone stored in the pattern memory are The feature is to output repeatedly in the order of steps.

The invention according to claim 2 is characterized in that, for each step of the pattern memory, a strength setting memory for determining the strength of the output sound in the step is set. The invention according to claim 3 is characterized in that a length setting memory for determining a length of an output sound in each step of the pattern memory is set for each step.

According to the present invention constructed as described above, if information of a single tone or a multiple tone is previously written in each step in the pattern memory, the chord is automatically stored in the pattern memory after the chord is input. Since the musical tone is output according to the content, it is possible to output not only a single tone but also a wider distributed chord including a double tone. According to the second aspect, the numerical value to be written in the memory for setting the strength can be adjusted.
Conversely, if it is set to zero, a rest will be set, so that an output pattern can be set according to the preference. Furthermore, since the numerical value to be written into the length setting memory can be adjusted in claim 3, staccato can be achieved by setting a small numerical value, and tenuto can be achieved by setting a large numerical value.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing a hardware configuration of a distributed chord output device according to an embodiment of the present invention. As shown, the distributed chord output device has a key for reading information on a depressed keyboard 1. A scanner 2, a CPU 3 serving as a control center, a ROM 4 storing a system program, and a RAM for reading and writing data
5, a timer 6 for setting time, a pattern memory 7,
And a sound source 8 that actually outputs a tone signal in response to a command from the CPU 3.

The pattern memory 7 has a matrix storage pattern as shown in FIG. 2, and a plurality of steps (eight in this case) correspond to a plurality of pitch bits (eight in this case). , One bit is assigned to each. An index (0 to 100) indicating the intensity of the output sound and an index (1 to
100) is set.

Next, the operation of the embodiment constructed as described above will be described. First, a musical instrument player sets data in the pattern memory 7 in advance according to his / her preference. In the example shown in FIG. 2, since there is data only for four intervals from interval bit 0 to interval bit 3, a chord input of four tones is assumed. Here, for example, when the player simultaneously presses the keys of "do, mi, s, shi", the pitch bit 0 is "do", the pitch bit 1 is "mi", and the pitch bit 2 is
Is assigned to the pitch bit 3 and "S" is assigned to the pitch bit 3, and the musical tone information is output in time series in the order of steps 1 to 8.

More specifically, in step 1, only the pitch bit 0 is set to "1" and all other bits are set to "0", so that a single note "do" is selected.
Since the length is set to 80, a sound of "do" according to the strength and the length is output. Similarly, "mi" in step 2, "so" in step 3,
In this example, "shi" is output as a single tone, and in step 5, both pitch bit 0 and pitch bit 1 are set to "1", so that the double tone of "do" and "mi" is selected. Since the length is set to 10, this double tone is output only for a very short time. In other words, "do,
The double tone of "mi" will be output in staccato.

Next, in step 6, since "Mi, Soo" is selected, this double tone is output. However, since the intensity is set to 0, no output is made. That is,
Rest state. In step 7, since the double tone of "So, Shi" is selected and the length is 100 (maximum value), the chord of "So, Shi" is output as a tenuto. In step 8, since all of "do, mi, so, shi" are selected and the strength is set to 100 (maximum value), the chord of "do, mi, so, shi" is accented. Output.

When the musical tones set as described above are described by musical note symbols, they are as shown in FIG. 3, and the melody is sequentially repeated to output musical tone information. That is, if the data as shown in FIG. 2 is stored in the pattern memory 7, the player can perform the simple operation of pressing the chord "do, mi, soshi, shi" as shown in FIG. It is possible to output a musical tone which repeats such a melody sequentially.

The information shown in FIG. 2 actually corresponds to FIG.
Are stored as a series of data in the pattern memory 7 as shown in FIG. In FIG. 4, "h" indicates a hexadecimal number and "b" indicates a binary number.

As described above, according to the present embodiment, when a dispersed chord is output from a depressed chord input, not only a single tone but also a double tone combining two or more single tones and the depressed chord itself Can be set as an output pattern, so that the range of performance can be remarkably widened, and musical tones according to the player's preference can be easily set and output. In addition, by arbitrarily setting the intensity of the sound and the length of the sound, staccato, rest, tenuto, accent, and the like can be set, and a wider range can be set.

In the above-described embodiment, the chord input is shown as an example composed of four sounds of "do, mi, so, shi". However, this is not limited to four sounds, and FIG. It can be set for the number of pitch bits shown (8 in this case). Although the number of steps is eight in the example of FIG. 2, the present invention is not limited to this, and may be less than eight or more than eight, and may be arbitrarily set according to the player's preference. Can be.

[0018]

As described above, in the distributed chord output device of the present invention, not only the single note constituting the chord but also the double tone combining two or more single notes is set for the input of the depressed chord. Therefore, the range of setting of the output pattern is expanded, and it is possible to easily set the output pattern according to the preference of the player. Furthermore, since the sound intensity and sound length can be set for each step, information such as staccato, rest, tenuto, accent, etc. can be arbitrarily set, and a wider output pattern can be set. Can be set.
