Abstract

PURPOSE:To select output routes full of variety and to usefully and effectively output musical sounds with limited channels by providing a free route besides respective output routes and providing an output route discriminating device which finally determines a route. CONSTITUTION:An output request is outputted from a musical sound output request device 1 together with output route information. An output distributing device 2 determines one of a left route L, a right route R, and a free route F as the output route based on route information and connects a route changeover switch 3 to the contact corresponding to the determined route. In the case of L or R, musical sounds are outputted from a channel speaker 5 or 6 of L or R; but in the case of F, musical sounds are sent to an output route deciding device 4, and the speaker of L or R is determined as the final output route in accordance with route information, the classification of musical sounds, the sound emission timing, random number information of a random number generator 7, and the state of each output channel or combination of these conditions.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to output path switching for an electronic musical instrument having a plurality of output paths.

Conventional technology It has multiple output paths than before, and depending on the type of musical tone,
Alternatively, a multi-path output device is known that switches the output path depending on the output timing.

Hereinafter, a two-path case will be described as an example of the above-mentioned conventional multi-path output device with reference to the drawings.

FIG. 3 shows a basic configuration diagram of the conventional multi-path output device. 1 is a musical sound output requesting device, which accepts keyboard input,
It performs switch input, MIDI input, or output requests at each timing during automatic rhythm/auto accompaniment nutat. 2 determines the output route by an output route dividing device. 3 is a route changeover switch. 5 is an L channel speaker, and e is an R channel speaker.

The operation of the multi-path output device configured as shown in FIG. 3 will be described below.

First, a musical tone output request is sent from the musical tone output requesting device 1 to the output path dividing device 2 together with output path information. The output route distribution device 2 determines the output route as L (left) or R (right) based on the output route information, and connects the route changeover switch 3 to the a side or the b side depending on the result. For example, if the output route information is "L output (left channel output)", the route changeover switch 3 will be connected to the a side, and as a result, musical tones will be output from the L channel yv speaker 5. The same applies when the output route information is "R output (right channel)".

Problems to be Solved by the Invention However, in the above configuration, it is always the L output or the R output.
The output is fixed, so for example, percussion hand claps or sound effects.

The musical tones that can be output from either R are fixed, and do not sound as varied and natural.

Also, if the output channels for the L and R outputs are limited, only one path is biased, and even though there is an empty channel on the opposite path, musical sounds that can be output from either side are not bothered. There has been a problem in that a musical tone that is already being sounded may be damaged by forced output from a route where there is no empty channel.

The present invention overcomes the above-mentioned problems and provides a multi-path output device that can select an output path suitable for the musical tone to be output and further output effective musical tone even with a limited number of output channels. It is.

Means for Solving the Problems In order to solve the above problems, the multi-path output device of the present invention provides an F (free) path in addition to each output path, and performs output path judgment to determine the final output path. It is equipped with a configuration called a device.

Operation The present invention, with the above-described configuration, can select a natural output path that is rich in non-uniform variations, and can also output musical tones efficiently and effectively even with a limited number of output channels.

Embodiment Hereinafter, a multi-path output device according to an embodiment of the present invention will be described with reference to the drawings, as an example of a case where drum percussion is output through two paths.

FIG. 1 is a basic configuration diagram of an embodiment of the present invention described above. In FIG. 1, 4 is an output route determining device which determines the final output route. 7 is a random number generator, and 8 is an output path memory that stores output path information such as for each type of musical tone or each output timing. Note that 1 is a musical tone output requesting device, 2 is an output path distribution device, 3 is a path changeover switch, 6 is an L channel speaker, and 6 is an R channel speaker, which are the same as those in the conventional example.

The operation of the multi-path output device of this embodiment configured as described above will be described below.

First, the musical tone output request device 1 outputs a musical tone output request together with output route information. The output divider 2 divides the output route into L (left), R (right), and F based on the output route information.
(Free), and depending on the result, connect the path changeover switch 3 to the a side, the b side, or the C side. If the output path is L or H, the path changeover switch is a,
L channel speaker 6, R channel speaker connected to side b, respectively.
It is output from the channel speaker 6. F (free)
If it is divided, it is sent to the output route determining device 4. The output path determination device 4 determines the output path based on the output path information sent with the musical tone, the timing of the musical tone type 2, random number information from a random number generator, or the status of the output channel of each output path. The final output path is determined to be either L (left) or R (right) according to an arbitrary combination of conditions. When L (left) and B (right) are determined, the L channel speaker 5. Each is output from the R channel speaker 6.

Table 1 Table 2 Tables 1 and 2 are specific examples of output route information. 1st
In the example shown in the table, there are three channels: L channel, R channel, and F channel. In the example shown in Table 2, there are basically two channels, the L channel and the R channel, but the F channel is assigned depending on the state of the output channel, output timing, random number information, etc.

Next, some examples of specific output channel determination by the output route determination device 4 in FIG. 1 will be given.

For example, musical tones such as hand claps depend on the sound timing, and an effective performance can be obtained by changing the tone to R. Furthermore, although the L channel is basically fixed, in the case of musical tones that may be output on the R channel instead of the L channel, the output is normally on the L channel, and may be output from the R channel depending on the channel status, random number information, etc. This corresponds to the example in Table 2. Also, if it is better not to fix the output channel, such as for sound effects, use random number information.

Effects can be obtained by distributing R.

Effects of the Invention As described above, the present invention provides an F (free) path in addition to each output path, and by providing an output path determination device, it is possible to allocate the final output path of the F path.
- It is possible to realize a multi-path output device that can select natural output paths with a wide variety of variations, and can output musical tones efficiently and effectively even with a limited number of output channels.
