Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tuning apparatus for outputting a reference frequency (hereinafter, referred to as a reference sound) as a reference for tuning when tuning the sound of a musical instrument or a tone signal.

[0002]

2. Description of the Related Art Generally, a tuning fork and a tuning flute close to A4 (note name A of octave 4) = 440 Hz are known. There are also known a tuning device that outputs an A4 reference sound and a chromatic tuner that outputs a reference sound for 12 tone names (referred to as chromatic). In addition, there is known a chromatic tuner that can output a reference sound even for a note name and an octave (a pitch of a perfect eighth).

[0003]

Heretofore, in the case of a tuning fork or a tuning flute, only a very limited number of reference sounds, such as A4 and B ♭, have been produced. Also, with this method, there is considerable deviation from the reference frequency,
It was difficult to produce an accurate reference sound.

In order to improve this method, the frequency is divided by a microcomputer using a crystal oscillator or the like as a reference clock, and A4 = 440
A tuning device that outputs a very accurate reference sound as compared with a Hz, and a reference sound is output by accurate frequency division for 12 note names (called chromatic) in addition to A4 = 440 Hz. Chromatic tuner has appeared.

However, as shown in FIG. 3, a chromatic tuner for outputting this accurate reference tone can be selected for only 12 note names or 12 note names and octaves. Therefore, it is necessary to understand all pitch names and octaves required for the musical instrument to be tuned. In particular, if the beginner does not remember the pitch of the instrument to be tuned in comparison with the note name and the octave, he or she may select the wrong reference tone and tune. Also,
In the process of selecting the required reference sound, unnecessary reference sounds are not always output. For stringed instruments such as guitars and basses, tuning styles (types) vary widely, and normal tunings (types) are used. In addition to regular tuning, various kinds of tuning methods applied in a tuning style called open tuning and a playing style such as jazz have been generalized.

Under such circumstances, not only beginners but also many general users select a reference tone by examining a note name and an octave from a reference material to determine a pitch to be adjusted according to a tuning style. Are often seen. Since the reference tone to be tuned differs for each instrument, for example, when a guitar user tunes another stringed instrument such as an ukulele or a viola with the reference tone, similarly, the pitch name and the octave of the pitch to be matched are similarly set. -After selecting the reference sound, the user has to select the reference sound.

Further, in such a tuning apparatus, when the pitch of a reference tone to be tuned is different from a plurality of pitches, it takes much time and effort to select a note name and an octave. In the process, a reference tone unnecessary for tuning is also generated, and it often takes time to tune.

The present invention has been made in view of the above problems, and has as its object to provide a tuning apparatus capable of accurately and quickly outputting a reference sound in various musical instruments and tuning styles. .

SUMMARY OF THE INVENTION According to the present invention, there is provided a tuner provided with an output means for outputting a reference sound serving as a reference for tuning a sound of a musical instrument or a musical tone signal. Input means, storage means for storing a plurality of tuning patterns and tables of reference tone data corresponding thereto, receiving an input signal from the input means, and receiving a desired reference from the table stored in the storage means. Control means for extracting sound data. For example, by using a plurality of types of instrument-specific reference sounds as the table of the storage means in correspondence with each tuning pattern, the tuning can be accurately and quickly performed for all instruments and tuning patterns using the reference sounds. The feature is that it can be done. In addition, by selecting the instrument and tuning pattern that you want to tune from the outside via input means, and outputting only the reference sound specific to the selected instrument, it is necessary for tuning, especially for beginners of all instruments. It is also characterized by the ability to easily select the correct reference sound without error. Further, in the present invention,
A user who owns a plurality of instruments can quickly select a reference tone dedicated to each instrument with one tuning device, and in the process, outputs a reference tone unnecessary for tuning. Disappears. Further, the table of the storage means is stored in a user
By making it possible to rewrite the reference tone table dedicated to the user, quick output of the reference tone necessary for all tunings can be performed, and the tuning time is shortened and troublesomeness is improved.
