5 stars: You can control the tempo, and the levels of each part.. The one Improvement I would request, is and easier eay to control playback, and perhaps select a few measures to repeat. as it is, you have a bar the shows progress to the entire song. but there is no practical way go back to a specific section.
5 stars: Please include in your update a personalized background or slideshow... Improve your search engine on the Playlist... Put a fast scrolling feature on the playlist for number of midifiles...
4 stars: But... How does one EXIT this App? I close its Android window, and it keeps playing in the background. The Menu doesn't provide an option to SHUT IT UP... I've therefore dropped my rating to 2-stars!! But, still, this is a GREAT APP, if you have the MIDI type of computer files or modules. I've developed my technical knowledge in this subject matter and can tell you that MIDI Clef is excellent. It is worth getting the paid version.
4 stars: The greatest midi app ever of all time. I rated it 4 stars but not because of the app itself, but because of the sound when changing a soundfont to a larger soundfont (large soundfonts like 1 GB or more). I would like to prefer if you can make an update which the sound could not be cut when you play a midi file with a large soundfont on it. I will rate 5 stars if you make my request to your app.
3 stars: What is there is great but it can't change pitch or tempo which is very disappointing.
3 stars: App is great...
