MIDI

Musical Instrument Digital Interface (.mid)

Lolly opens this format

Not a recording but a score: MIDI stores which notes to play and when, so the file is tiny and the sound is produced on playback. Lolly converts an imported .mid into a small on-device synth track you can use as a music bed, capping note and step counts so a pathological file can't hang the tab.
