### 5/5 — Best!

*2026-05-13, version 4.9.7*

Great software for live performance!

### 4/5 — Kaufoption?

*2026-03-11*

Wo kann ich diese App kaufen? In-App finde ich keinen Button.

### 5/5 — 最高のMIDIプレーヤー

*2026-02-16*

このアプリが一番使いやすかったです。
要望なのですが仕様なのかわかりませんがミキサーで変更した内容を 共有する MIDIに反映して欲しいです。

### 3/5 — good but 1 problem

*2025-10-05*

i use this app all the time, it’s probably the best midi player for me on my iphone. i want to use it on my mac, but the problem is i cannot redownload this on my mac because the mac version is listed as a separate app than the ios version. so, if i wanted to use this on my mac id have to pay again to use it. which, i am not going to be doing. i use the trail version of this from the website instead on my mac. it’s annoying that i can’t hear the last quarter of a song just because the mac version is separate from the ios version.

**Developer response:** The Mac version is a completely different software (as is the Windows version) and each platform requires a separate license.

### 1/5 — 自分の曲が聴けない

*2025-08-17*

ファイルを使ってこちらのアプリで、再生しようとしたらファイルの読み込みに失敗しました。と出て、2500円払わされるところでした。

**Developer response:** "Failed to load file" means there is a problem with that particular MIDI file.

### 1/5 — Not available in my region

*2025-07-12, version 4.9.3*

Not available in my region

### 4/5 — Fonction loupe

*2025-06-14*

Bonne appli mais je n’ai pas réussi à trouver comment définir une boucle pour répéter une section d’un morceau. Cette fonction est-elle implémentée ?

**Developer response:** It's possible on iPad but not on iPhone.

### 4/5 — Best IOS Midi Player

*2025-05-05*

The App is still the best Midi Player for IOS. I just hope that the Devs can still upgrade the app, such as midi editing (program changes in GM2, GS, and XG), control changes such as velocity changes (not just volume), and a lot more. Please Devs im still patiently waiting for this updates. Thank You!
