Very good I just love it

Cool

Works great!

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.

Response from developer

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!

I want to preview percussion

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

Used to work. Now it doesn't.

SAVE MIDI ON THE IPHONE!

Great app! A few suggestions though…

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.
