### 5/5 — Very good I just love it

*2026-06-30, version 3.2.5*

Cool

### 5/5 — Works great!

*2026-06-13*

This app does what it says with no fuss. I've tried a bunch of mids and soundfonts through it and all works as expected. The Playing Next feature is super handy as well.
The app works well with VoiceOver as well everything's clearly labeled. I like the little track viewer too. Hear the various parts of a midi in isolation.
Well done.

**Developer response:** Hi, thanks for leaving a review! Glad to hear that you're enjoying the app. P.S. If you have any feedback on the VoiceOver support and how I could make it better, please feel free to reach out via the App Support link in the Settings screen. Thanks!

### 2/5 — I want to preview percussion

*2026-06-11, version 3.2.5*

I paid $8 thinking the fee would allow me to preview drum tracks. Nope just piano. Wasted my money. Please fix this wtf

### 2/5 — Used to work. Now it doesn't.

*2026-05-21, version 3.2.5*

SAVE MIDI ON THE IPHONE!

### 5/5 — Great app! A few suggestions though…

*2026-05-15, version 3.2.5*

So this app is *amazing*, but i think there are some much needed quality of life changes. 1. Pause the audio when a Bluetooth audio device connects/disconnects, and 2. Add a toggle for if changing sound font restarts the midi. Also, the sound font “alex_gm.sf2” crashes the midi player.

### 5/5 — Awesome

*2026-04-26*

This app has been good to me. I love it after my friend showed me how to use it then I was good and now I can play my files and now I could play the Janktech sound font

**Developer response:** Thank you! Glad to hear that you are enjoying the app.

### 5/5 — OMG BEST APP EVER WHAT

*2026-04-25, version 3.2.5*

I’VE BEEN TRYING TO PLAY THE MUSIC FROM KIRBY MASS ATTACK FOR SO LONG BUT I COULDNT FIND SOMETHING THAT COULD PLAY IT CORRECTLY AND NOW I’VE BEEN BLESSED BY THE HOLY NS MIDI PLAYER APP AND ALL MY LIFE PROBLEMS ARE SOLVED

### 3/5 — It’s fine but crashes often

*2025-12-08, version 3.2.3*

For $7.99 I would expect less crashes and more stability

### 2/5 — Can’t you save the playlists?

*2025-11-16, version 3.2.3*

It is paid to make the playlists at the moment, nice audio but the app for musicians or listeners is not practical at all.

### 4/5 — Cool but one thing I should suggest though

*2025-10-12, version 3.2.3*

It's awesome but I want you to add an update which let you replace the soundfont's instrument,for example: changing a guitar to a piano
