Description

[Detailed explanation of the idea] [Industrial application field]

The present invention is based on a storage means for storing and reading musical tone information representing a musical tone, and a supply of musical tone information read out from the storage means. The present invention relates to a sequencer having musical tone generating means for generating musical tones.

[Conventional technology]

A conventional sequencer has a storage means for storing musical tone information representing musical tones and for reading it.
Furthermore, based on the supply of musical tone information read from the storage means, the musical tone generating means for generating the musical tone represented by the musical tone information also had only one channel. Therefore, the musical tone information previously stored therein is read out from the storage means as the first musical tone information, and is supplied to the musical tone generating means to generate the first musical tone information.
Even if the musical tone represented by the musical tone information can be generated as the first musical tone from the musical tone generating means, the first musical tone is stored in the storage means while the musical tone generating means generates the first musical tone. Another second musical tone representing a second musical tone different from the first musical tone.
Further, the musical tone generation means could not simultaneously generate the first and second musical tones represented by the first and second musical tone information, respectively. Therefore, while listening to the musical tone (for example, the first part of an ensemble) stored in advance in the storage means as the first musical tone, you can listen to the second musical tone (for example, the first musical tone is the first part of the ensemble). if so, for example the second part of the same ensemble)
is stored in the storage means, and the second musical tone thus stored in the storage means and the second musical tone are stored in the storage means.
This has the drawback that it is not possible to simultaneously listen to the first musical tone previously stored in the storage means, which was listened to when the first musical tone was stored in the storage means.

[Purpose of invention]

Therefore, the present invention aims to propose a novel sequencer that does not have the above-mentioned drawbacks.

[Means to solve the problem]

The sequencer according to the present invention is based on a storage means for storing and reading musical tone information representing musical tones, and a supply of musical tone information read from the storage means, as in the case of conventional sequencers. and musical tone generating means for generating the musical tone represented by the musical tone information. However, the sequencer according to the present invention
In such a sequencer, (a) the storage means stores first musical tone information representing a first musical tone, and a first channel storage means for reading out first musical tone information representing a first musical tone; (b) said musical tone generating means is configured to read out second musical tone information from said first channel storage means; first channel musical tone generation means for generating the first musical tone based on the supply of the first musical tone information; and the second musical tone information read from the second channel storage means. Based on supply,
a second channel musical sound generation means for generating the second musical sound, and () the storage means:
(a) From the storage means of the first channel, the first
(b) the second musical tone information is stored in the storage means of the second channel while reading the musical tone information to be supplied to the first musical tone generating means; The first and second musical tone information is simultaneously read out from the storage means of the first and second channels so as to be simultaneously supplied to the musical tone generating means of the first and second channels, respectively. ing.

[Action/effect]

According to the sequencer according to the present invention, ()(a)
The storage means for storing and reading musical tone information representing musical tones has two channels, a first channel storage means and a second channel storage means, and (b) from the storage means. The musical tone generating means for generating musical tones representing the musical tone information based on the supply of the musical tone information to be read also has two channels consisting of the musical tone generating means of the first channel and the musical tone generating means of the second channel. has and also
(a) The storage means reads out the first musical tone information from the storage means of the first channel in order to supply it to the first musical tone generating means, while reading out the second musical tone information from the storage means of the second channel. (b) storing the first and second musical tone information from the storage means of the first and second channels;
and the musical tone generating means of the second channel.
While generating the first musical tone represented by the first musical tone information stored in advance in the musical tone information storage means of the first channel, a second musical tone representing the second musical tone is generated in the storage means of the second channel. Therefore, while the musical tone generation means generates the first musical tone represented by the first musical tone information, the storage means can store musical tone information other than the first musical tone. (b) other second musical tone information representing the second musical tone;
Simultaneously generate first and second musical tones respectively represented by first and second musical tone information stored in advance in the storage means of the first and second channels from the musical tone generating means of the channel. Therefore, from the musical tone generation means, the first and second musical tone information represented by the first and second musical tone information, respectively.
musical tones can be generated simultaneously. Therefore, while listening to the musical tone (for example, the first part of an ensemble) stored in advance in the storage means as the first musical tone, you can listen to the second musical tone (for example, the first musical tone is the first part of the ensemble). if so, for example the second part of the same ensemble)
is stored in the storage means, and the second musical tone thus stored in the storage means and the second musical tone are stored in the storage means.
It is possible to simultaneously listen to the first musical tone previously stored in the storage means that was listened to when the first musical tone was stored in the storage means.
