KORG has answered the question: “Can a tuner recognize good sound?” With the KORG cortosia youll see whats missing from “good sound” with just a glance. Even practice thats slightly boring (such as practicing the production of single notes) will become enjoyable. The cortosia is a completely new type of interactive tuner app designed to improve the overall quality of sound produced by the artist.

* Analyzes five elements of “good sound” and rates them in real time
* Automatically records “good sound” so you can check your daily improvement in technique
* Lets you compete against the world in “good sound” and vie for ranking
* Supports flute, clarinet, trumpet, violin, cello, saxophone, trombone and euphonium

Analyze five elements of “good sound” and rate them in real time:
Just what is “good sound”? Beautiful sound, pleasant sound, sound that resonates in the listeners heart. Perceptions of “good sound” differ between people, but could there be some commonalities? Through cooperative research with Pompeu Fabra University in Barcelona, Spain, under the direction of Professor Xavier Serra, Korg has arrived at a technology “Artistry” (*1) for evaluating “good sound” based on five elements.

1: Pitch Stability
2: Dynamic Stability
3: Timbre Stability
4: Timbre Richness
5: Attack Clarity

Simultaneously with the tuner display, a radar chart shows the results of analyzing these five elements in real time, and scores them on a scale of 100 points. While tuning, you can see at a glance what aspects of your tone are lacking. You can also listen to a model tone and hear how it differs from your own sound. This is highly recommended for beginners who have just started a musical instrument, as well as for intermediate players who want to advance to the next level.

*1: Automatic Rating Technology for musical InSTRument plaYers

Automatically record “good sound,” and check your daily advances in technique:
Data is automatically recorded and kept when tuning and scoring. You can audition the accumulated recording data or recall a radar chart for it, and you can also check the number of hours you practiced and your best score for each day. By looking at your past results, you can see how you are progressing. In addition, you can post your score to a social networking service such as Facebook or Twitter allowing you to record or upload your daily progress (or backsliding) as if you were writing a diary. Whether you use this to compete with your friends or to give encouraging comments, its a great way to improve your skill while enjoyably sharing information.

Compete with the world for “good sound”:
Your ranking is compiled by averaging your highest score for each note, and displayed. Youll be able to see your current position among performers around the world who use cortosia.

Supports flute, clarinet, trumpet, violin, cello, saxophone, trombone and euphonium.

A full range of basic functionality including tuner, metronome, and level meter:
In addition to a chromatic tuner that benefits from Korgs forty years of know-how in tuner development, theres a metronome that supports tap tempo, and even a level meter, making cortosia a great partner for performance or practice.

Korg hat hier mal wieder eine meisterhafte App freigelassen!

意味不明

追加されたサックスを目当てに購入。 どうやら音が切れる零コンマ数秒前を評価対象としているらしく、音が途切れる度にぶれた評価が表示され続けるので、何が良くて何が悪いのか、全くわかりません。少なくとも数秒間は評価を累積して、その間の平均値を表示してくれないことには全く使えません。

動作不良

iOS9.02,iPhone6sPlusで動作不良ですね。改善を求めます

肝心の

i Phone 6sではチューナーが動作不良です。改善をお願いします。

対応楽器を増やして欲しい

コンセプトは面白いですが、対応している楽器が少ないです。 ユーフォニアムやコルネットなど英国式金管バンドで使われる楽器に対応して欲しいです。 メトロノームはチューナと同時に使えると嬉しいです。

自分の弱点が一目でわかる

ピッチや音量の安定性などが一目でわかるので、自分の弱点を確認するのに使っています。 今のところロングトーンのみの対応なので、メロディにも対応できたらいいなと思います。

買う価値あるの?

なにこれ? メーカーのホームページに移調範囲とか表記されてるけど、移調機能はないです。実音表記のみ。チューナーとしてなら他のアプリの方が安くて高機能です。
