Ratings and Reviews
Midi Opener - Review
Great App! Fair price! Would give five stars if you add these two features:
1) Give us an option to build a Library structure with unlimited nested folders with lengthy naming conventions AND allow us to populate folders with pointers (NOT the actual Midi files) TO the Apple FILES app (like your folder that already does this). So, we get the juke box effect without having to hunt down and import the actual files every time.
2) Make this app as both "Stand alone" AND as an AUV3 plug-in, that can be hosted by ios "Hosts" like AUM, Ape Matrix, various DAWs like GB, Cubasis, Loopy Pro, Zenbeats, Nano Studio 2, Logic Pro for Ipad, etc. At an absolute minimum make it function as an IAA with audio hosts. (dinosaur legacy, but theres a ton of em' out there, better than nothin')
I love the features you include in your app, such as the ability to optionally use a different Soundfont, change tempo, and key, turn effects on and off individually, optional EQ section AND you actually display the name of the file (allowing lengthy titles, as Midi files can be). Well done! Stay with it!
good app but…
I love how I’m able to change instruments and tempo but the changing key option breaks every song, because whenever I open the app with the song I played before, it sounds fine, but when I choose a different song, the song is in the key of the previous one, and I always have to manually change the key, and I’m getting annoyed of this, so can you please remove the change key or at least fix it? that would really help!
Developer Response ,
Update to version 4.2 for the key transposition fix.
Awesome
I very much enjoyed this app. It is one of the few free midi applications, and it opens my files very well. The sound font to built in to the application actually does not sound too bad, when comparing it to the one built into my windows PC. I dream feature would either be trans pose the sound, or load a custom sound font, but like I said, it’s a dream feature. It’s free, and it does everything a free app should do. I especially like how closely integrated it is with the system, being able to play midis in the background.
Developer Response ,
Now you can transpose the song’s key with MIDI Opener! Thanks for your feedback.
