Soundfont Player:
-----------------
Any soundfont of file format sf2 or sfz can be used, also compressed soundfonts (wavpack or flac).
The soundfont that ships with this app offers acceptable sounds in relation to its size: just 3 MB. Its just something to start with. Anyway you should use your own soundfont. One of the most popular free soundfonts is  "Chorium (Revision A)"  (27 MB) by openwrld.

Visualizer:
-----------
By coloring the notes depending on their pitch the harmonic development, different tonal areas / modulations / key changes become visible at a glance! 
Even large MIDI files (eg. a symphony) will be visualized in 2-3 seconds ! 
Also so called "black midi" files (up to million notes or more) can be played back completely. Only the number of notes to display needs to be limited. You can set this number -> Try how many notes your device can take (e.g. with Nexus 7 up to 400.000 notes)

MIDI file user settings
----------------------
All loops, markers, instrument/track assignments are stored in a separate settings file. Each time a MIDI file gets loaded it will search for an existing settings file.
