### 3/5 — コンセプトは素晴らしい

*2026-06-23*

全体的に不満はないですが、やはりテンションはアボイドノートも含めて自由に選べるようにしてほしい。不協和音になるのは分かるし一般的に使われないかもだが、M7 (11)なども選択できるようにできたら完璧。設定でオンオフできるようにすれば良いと思います。

**Developer response:** コメントありがとうございます。
コードの組み合わせの選択範囲について、ある程度の拡張であれば検討することは可能です。基準はアボイドノートになるかと思います。
ただ、コードを学ぶ観点からは、アボイドノートまで加えると、複雑なアプリになりかねないため、直近では優先度は高くないと思っていただければと思います。（評価を再考していただければ、検討することもできます。）
よろしくお願いいたします。

### 5/5 — すごく良いです

*2026-04-18*

曲作りにとても役にたちます。
思いついた時にすぐメモ代わりに登録できるところ。
ありがたいです。

### 5/5 — 画面右に【登録】と表示されている

*2026-03-24*

【レビュー内容の誤りと訂正】
早速、デベロッパ様より対処方法についてメールを頂きました。ご返信ありがとうございます。
【登録ボタンの件】以前からとのことで私の誤りです。誠に申し訳ありません。

【課金内容の件】『設定』より『機能の拡張』→『復元』で回復することを確認しました。

Ver3にて機能拡張されてましたことと、私の曖昧な記憶が重なり、画面表示が少し違って見えただけでした。

以前通り、使用出来ています。
ご対応、ありがとうございました。


【以下は当初のレビューとなります】

久しぶりにアプリを立ち上げたら、右上に【登録】とボタンが表示されています。
課金していたのは無効化されたのでしょうか？
iPadOS 26.3.1 へのアップデートの影響なのかもしれません。
使おうと思って開いたのに残念です。

**Developer response:** コメントありがとうございます。
Ver.3にて機能の大幅な拡張を行いましたが、基本的な機能は変わっていません。
右上のボタンは「登録／再生」の画面切り替えのボタンでして、表記は以前から変えていません。（【登録】は小節の追加と音楽コードの登録を行うことを意味します）
もちろん、以前に課金された内容は保持されています。画面左上のメニューから【設定】の「機能の拡張（要アプリ内課金）」を選択して、アプリ内課金画面の「復元」ボタンをタップしてください。機能が復元されます。
ぜひ、新たなバージョンを少し試していただき、またこちらにご連絡いただけるとうれしいです。

### 5/5 — Simple chords app that works

*2026-03-06*

Love how the app made chords feel easier to learn memorize play with systematic UI

### 5/5 — How to purchase instruments

*2025-04-10*

How to purchase instruments

### 4/5 — ペダル踏むと落ちる

*2025-03-16*

Midiキーボード繋いで、サステインペダルを踏むとアプリが落ちます。モデルはyamahaのfc3aとかいうやつです。

**Developer response:** [更新] 
コメントありがとうございます。
また、クラッシュするとの情報もありがとうございます。
こちらでもサスティンペダルで確認しましたが、クラッシュの再現には至りませんでした。
もし症状が発生したとしますと、MIDIのコントロールチェンジ（CC#64）を受信したときが考えられますので、その周辺の処理を見直して、アップデートしたいと考えております。
引き続き、よろしくお願いいたします。

### 5/5 — Great tool

*2024-08-06*

+++

### 3/5 — 機能は多いがコードの表示はイマイチ

*2023-12-06*

バッハの平均律がコードで正常には表示されない。あまり実用的ではないものの、ちょっとした調べものにはよいかも。

**Developer response:** コメントありがとうございます。
ご指摘の「バッハの平均律」によるコード表示について、ご要望の例をご教示いただけるとうれしいです。
今後の参考にさせていただきます。

### 1/5 — keys stick

*2023-01-24*

unusable so far.

**Developer response:** Thanks for your comment.
Please try with latest version (3.0.x).

### 5/5 — Took me time to figure out the controls

*2022-09-19*

Initially I tried this on a Mac and I couldn’t get the chord selector screen to pop up; despite reading the instructions several times. So after 20 minutes I gave up. After a “chat” with the developer, I tried it on my iPhone. Hurray, the chord selector popped up and I was able to select a few chords and play them. I’ll try again on the Mac to see if I can get the chord selector to pop up. I must admit the process of toggling the edit/play button AND the Register/Playback button slightly unintuitive. Maybe if the buttons were separated so toggling wasn’t necessary, it would be more clear what’s going on. The toggle feature has the unfortunate effect of hiding the other function. Once you know this, it’s ok, but initially, it’s confusing. And those first few minutes with a new app are crucial. I do t know if it’s possible, but I’d like to modify the standard chords to match certain songs. So I can play along and correct the MANY mistakes in Chordify and actually play the chords in the original song.

**Developer response:** Thank you for your comment and message.
Since we cannot guarantee the operation on Mac, we'd like you to try this app on iPhone/iPad.
Thank you for pointing it out in your message regarding the UI. I'd like to continue to update so that it is easier to understand.
Please update your comment again if you have any requests.
