### 3/5 — Micro key solution:

*2025-12-09, version 1.0.1*

If you have an old Microkey Air you need to update your Microkey’s firmware on a computer for this to work. First download an install the windows/Mac driver and check it installed. Then download the firmware updater, but before running it you need to switch to usb mode, then put the keyboard into update mode by holding left octave button and leftmost key when plugging the usb cable in, otherwise the updater won’t connect to the keyboard. Update the firmware then unplug, switch to wireless mode, then go back to your iOS device and the Bluetooth midi app will connect to the keyboard.

2 points off because bad design/user experience and it shouldn’t be THIS hard. The update mode key combo should have been written in giant red writing on the update page, not just hidden in the pdf instructions, and without knowing the key combo, the firmware updater itself just gave a nondescript could not connect warning rather than guiding you to the solution, it would have taken 10 seconds for the update coder to write “please check your device has been put in midi update mode” rather then the obtuse “device not found”.

One wonders how many of these things have ended up in landfill over user frustration.

### 2/5 — 複数のMIDI コントローラーが表示されません

*2025-04-03, version 1.0.1*

KORG NanoStudio とKORG nanoKEY Air2をPCからインストールしたのですが、nano KEY Air2が表示されません。どうすれば良いのですか？　本当は、KORG さんの方でアップデートして頂ければ良いのですが…
おかげで、nano KEY Air2が使えそうにない状況です…

追伸
おかげ様で、nano KEY Air2 は表示されましたが、今度はnano key fold が出てきません。PC でアップデートしようにも、対応していないようです。一体、どうすれば使用出来るようになるのでしょうか？　至急対応をよろしくお願い致します。

### 4/5 — 便利につかっています

*2024-10-28, version 1.0.1*

とてもいいです。ただ1点、同じMacアドレスのBLEが複数登録されますね。オフラインとして、消えない項目があります。ほかのBismarkさんなどのアプリからは、選択して削除できますが、こちらはできません。30を超えたあたりで、とても重くなりフリーズ気味になります。できれば、ご対応お願い致します。

### 4/5 — Funktioniert mit iOS18

*2024-10-06, version 1.0.1*

Nachdem ich Probleme mit iOS17 und iOS18 hatte konnte ich diese mit den Systemupdater für das Korg Microkey Air beheben. Leider musste ich eine ganze Weile suchen. Könnte man wirklich zugänglicher machen, daher nur 4 Sterne.

### 2/5 — Не переподключается к Iphone 15

*2023-12-03, version 1.0.1*

Достал из коробки, поставил приложение, Nanokey Studio подключилась. После отключения больше не подключатся. Версия прошивки самая новая, устройства bluetooth удалял, не помогает.

### 2/5 — iPadOS16,17接続不可

*2023-09-22, version 1.0.1*

iphone(ios16)、win10では接続可能です。
ファームウエア及び当アプリは最新版を使用しております。
修正お願い致します。

### 1/5 — Bluetooth not working on iOS despite the last update

*2023-02-21, version 1.0.1*

Could you please do something?

Thanks you per advance.

### 1/5 — 繋がらなくなった

*2022-10-12, version 1.0.1*

全然繋がんない。表示はされるけど、ずっとconnecting…..

### 1/5 — ハードとソフト音源のお金を返してほしい

*2022-07-23, version 1.0.1*

iOS15になった途端にキーボードとiPhoneが繋がらない。ファームウエアの更新をMacでアップデートモードにて接続する際もキーボードのLEDの表示が正しいのにアップデートプログラムがエラーでスキャンしない。

キーボード以外にソフト音源なども購入したのにガラクタになってしまいました。

### 1/5 — Not compatible

*2021-11-10, version 1.0.1*

Non compatibile con IOS15 e sistemi precedenti. Not compatible with IOS10.15 and previous systems

### 1/5 — Booooooooooo

*2026-07-26, version 1.0.1*

Doesn’t work

### 1/5 — Error en conexión

*2026-02-18, version 1.0.1*

No puedo conectar a aplicación, mi teclado microkey Air 61

### 1/5 — Junk software

*2025-11-17, version 1.0.1*

Korg nano key air 61 basically rendered useless. It’s gone from being my favourite method of making music to a frustrating mess of trying to fix using useless updates and reinstalls. Korg obviously gave up on support some time ago, and decided to just leave all us customers hanging in the hope they might fix it (one day). I’ll never buy another Korg product again, and my nano key is going in the bin. I’ll use another manufacturers controller instead.

### 1/5 — MIDI routing impossible

*2025-07-13*

I see my devices, they are connected, but no way to use my Nanokeystudio with my Seqtrak...

### 1/5 — Terrible drivers and support

*2025-03-25, version 1.0.1*

KORG is notorious for terrible drivers on Windows and sporadically on iOS. BLE MIDI app worked for a while but now detects Microkey for a few seconds before disconnecting. KorgUSA responded they are sorry I’m having problems and fob me off on their software support which just autogenerates a message it’s not their problem.

### 1/5 — NO CONECTA iOS 18

*2024-10-26, version 1.0.1*

Detecta el teclado por bluetoth y luego se desconecta
URGE ACTUALIZAR!

### 1/5 — Çalışmadı

*2024-07-05, version 1.0.1*

Çalışmıyor  güncelleyin artık .yeni telefon modellerine uygun yapın.

### 1/5 — iPadOS17以降の使用改善予定はありますか

*2024-01-31, version 1.0.1*

iPadで使用したいため、今後、iPadOS17以降の使用改善予定はありますか？
出来る、出来ないの情報いただけますと助かります。

### 1/5 — Problem microkey air

*2023-12-29, version 1.0.1*

Not connected with microkey air!!!

### 1/5 — Doesn’t work with iOS 16

*2023-07-23, version 1.0.1*

Once again, Bluetooth midi between Korg Bluetooth controllers and iOS is broken on iOS 16. Works on Mac. Just stop buying their stuff if you are looking to use it with iOS.  

Update: Korg told me to contact them below this review. I did contact them. They then told me that they couldn’t help me and I should contact the distributor of my MicroKey Air 25 (who of course cannot help me with a software/firmware issue for a device designed and manufactured by Korg). This is the lowest I have seen a company in Audio hardware go and it’s just such a disgrace. Just fix the damn thing or stop selling these controllers altogether! Any yes I’m on the effin latest firmware…

### 5/5 — Ottimo con iPad vecchio

*2024-08-22, version 1.0.1*

Sono riuscito ad utilizzare H90 control e a creare una connessione MIDI over Bluetooth 
tra un Ampero control e l’H90

### 5/5 — 繋がった

*2024-02-03, version 1.0.1*

なんのストレスもなくスムーズに繋がりました

### 5/5 — iPad Pro 11 Zoll M1 Chip TOP

*2024-01-14, version 1.0.1*

Seitdem ich mein neues iPad habe, funktioniert die App super. App öffnen MicroKey Air anschalten = stabile sofort. Perfekt mehr muss diese App nicht können.

### 5/5 — Great tool

*2023-08-21, version 1.0.1*

I use this for connecting to the Bluetooth receiver plugged into my Helix Stomp XL. Works a charm, even with a Bluetooth page turner connected to the same device.

### 5/5 — Works perfect on Ipad IOS 15.6.1

*2023-07-09, version 1.0.1*

Needed this app with my Korg Microkey Air which I was hesitating to buy since they were many reviews, stating that it would not work with Bluetooth. After adding this app, but keyboards works great on all keyboard and synth apps my Ipad pro, resulting in true wireless experience as no cables / hubs etc are connected which is ideal for traveling. It is worth noting that is app is only used once afterwards you don’t need to open it anymore. It is not active. Hope this helps!

### 5/5 — Nickel et parfait

*2023-02-26*

Je tenais à mettre un avis vu les commentaires négatifs .
Ça passe très bien avec l iPad et MacBook Pro .
Ça se connecte rapidement et aucune latence avec le Korg micro air.
Merci .

### 5/5 — It just worked. Thanks.

*2023-02-15, version 1.0.1*

The easiest app of all the BLE MIDI apps I tried. It just worked. Thanks.

### 5/5 — 優秀！

*2023-01-30, version 1.0.1*

海外製鍵盤Miselu C.24とXkeyAirをすぐ認識しました。
本家アプリ更新止まってるので助かりました。
iPadOS15.7.2

### 5/5 — Works fine in 2022

*2022-04-01, version 1.0.1*

Works solidly and easily with IOS 15 in 2022 with my Korg Microkey Air. I think many of the bad reviews are from a while back when there were iOS issues.
