### 5/5 — 本来の使い方では無いかもしれませんが

*2023-06-22*

メロディからコードを判定する時に多用しております。

### 3/5 — It crashes. Will not open

*2022-10-26*

It crashes. I can’t open it.

### 5/5 — 横画面対応感謝

*2017-05-24*

待ってました。横画面
最高です。

### 5/5 — 作曲に便利

*2016-11-06*

コードがすぐ確認できて作曲に便利です。手放せません。iPadに対応したり、安定性が増したり、ちゃんとアップデートしてるのも嬉しいです。

### 5/5 — très bien

*2015-08-28, version 5.1.1*

très utile pour progresser dans la compréhension des accords, des modes et autres.....

### 1/5 — Annoying ripoff

*2014-11-13*

This had potential BUT after paying good money for this app, it offers a limited number of chords in an individual chord progression. To use more you have to buy an 'advanced version'! Come on! This is not advanced functionality. It's the same functionality. The person who wrote and marketed tis has no idea. It's like using a demo version, but you pay for it without realising that you have limited use of basic functionality. What a fantastic way the annoy and drive away customers! App deleted.

### 3/5 — 何か思ったのと違いました……

*2014-08-13*

出来ればメロディーを弾いたり入力したら、それに合うコードを提案してくれたら嬉しいんですけど、結局はメロディーじゃなくて単音ですね……
 その単音を含むコードがズラズラズラと表示されるだけで、いわゆる自然なコード進行とかをどうするか？ とかって事の提案を期待して購入すると肩すかしを食ら事に……

ある程度音楽をかじってる人にとっては全く必要のないアプリです
 逆にどんなコードがあるのかを知らない初心者の人は、コードの勉強になっていいかも知れないですね

単音ではなく小節のイメージでコードつけてくれたら曲作りに役立つんですが…

### 4/5 — 非常に重宝しています。

*2014-03-03*

基本機能は希望を満たしています。chordの回転形が選択できたり、Chord Proguression でGate Time が設定できる等々のバージョンアップを期待しています。

### 3/5 — 惜しい。

*2013-01-04*

テンションとメロディは切っても切れない関係。これだとコードトーンのみでコード進行を作る事になってしまう。残念。改善に期待させて頂きます。

### 5/5 — うん

*2012-03-22*

いいね。
コード進行考えるのに役立つ！
