good but 1 problem

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.

Response from developer

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

Fonction loupe

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 ?

Response from developer

It's possible on iPad but not on iPhone.

Best IOS Midi Player

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!

Great app

This MIDI player has many features that are helpful. I have thousands of MIDI files I’ve collected over the years which this app handles well. I’d like to see a multi rename functionality with search and replace. I really appreciate the app developer. I’d encourage you to keep developing this for advanced use.
