File Type 2Extended MIDI File
.XMI File Association 2
Variation of a standard MIDI file that contains "time quantized" MIDI information; each note is exactly in sync with a certain beat, such as 1/16, 1/32, or 1/64; XMI files are usually a little smaller than a regular .MIDI files since they do not need to store as much timing information.
Because XMI files are similar to MIDI files, they do not contain any actual audio data.
