### 1/5 — Doesn’t work

*2025-01-27, version 1.1.7*

I can’t even get it to keep a connection never mind work. Can someone please resolve this issue or just remove the app.

### 1/5 — Massive battery drain

*2024-08-25*

The app is functional but drained 57% of my battery in one day. Please fix this.

### 1/5 — iPad mini4では使えない

*2024-04-12*

メーカーに以前から問い合わせていますが、改善されません。
KAWAIさん、なんとかしてください。

### 1/5 — Stopped working

*2023-12-12, version 1.1.5*

Used to work fine on my iPad Air2 and CA901 piano. Now it will not load.  Have deleted the app and reinstalled it but to no avail.  Could be an incompatibility with an operating system upgrade.

### 1/5 — Crashes all the time on iPad Mini 2

*2023-07-16*

I gave my son my old iPad Mini 2 with iOS 12.5.7 and the app does not even start. It crashes every single time. Please fix this

### 1/5 — 闪退 用不了

*2023-07-09*

闪退用不了

### 1/5 — No functionality

*2023-01-25*

The score starts playing songs automatically from your connected piano at 100% volume when you click into a score. There’s no option to change settings so that it doesn’t automatically do this so every time I want to open a score to play, it gives me a jump scare at how loud it plays out of my piano. Don’t know who designed it like this but they need to add settings so this doesn’t happen.

### 1/5 — iOSアップデート後起動しない

*2022-09-16*

セキュリティ問題対策されたiOS12.5.6にアップデート後、起動しなくなりました。
対応をお願いします。

### 1/5 — なぜか、、、

*2022-06-01*

iPhoneアプリから楽譜が見られません。。。
どうしたらよいのでしょうか？

### 1/5 — Why Kawai? Quality is really bad.

*2022-01-23*

- Left Hand is ignored and will be not played
- no practice modes (right hand / left hand)
- no metronome
- sounds cannot be change
- phrase cannot be defined for repeating 
- many songs missing

In General the only thing the app will do is to playback a part of the songs of your Kawai and even this is not working (just right hand will be played)

If you would offer this next to flowkey or any other piano app it should not even get 1 star.
I really would appreciate if there is a way to practice the internal songs of my CA99. But unfortunately the only thing you can do is playback. At least the internal playback function of the CA99 is working.

### 5/5 — Battery drain in the background and Loop play function is no longer available

*2024-01-27*

One of the recent updates must have had a bug where it keeps draining battery life in the back ground even when the app is not in use.  The drain is serious because it drains battery from 100% to 50% in less than 24 hours in the background.

Also the recent update removed the loop play functionality in the lesson. I can’t no longer loop a particular part which I really enjoyed in the previous versions. Could you fix the bug and bring it back please? I am using an ES110 by the way. Otherwise a great and very helpful app for Kawai electronic piano users.

### 5/5 — Nice app

*2023-04-19*

This is a nice app. I love I can use the middle pedal to turn pages. I just wish I could upload my own PDFs into the app so I could utilize the page turn feature.

### 4/5 — 反馈

*2023-06-06*

打开app太慢了！希望改进！

### 3/5 — Only Play the Right Hand Notes

*2021-12-28*

When I play the song, it only plays the right hand part. How do I fix it?

### 2/5 — 重复播放功能有bug

*2024-12-22*

我在用重复播放功能时候，大部分时间是正常的。
但是个别乐曲，从头到尾重复播放就会闪退。比如拜厄53、54就有这个问题。

### 2/5 — エリーゼのために等、練習曲以外の楽譜は見れません。

*2021-05-29*

課金で見れるようにしてください！
