Open MID File

The MID file extension is a name for a standard MIDI (Musical Instrument Digital Interface) file, which is used by MIDI hardware devices as well as music creation and playback programs.

The MID file contains musical data, such as notes played, when they are played, how long each note is held, and the velocity of each note, as well as other data related to musical notation.

MID files are used for interoperability between different types of software programs and hardware devices.

They can also include driver data for a device.

For example, a MIDI file, saved in MID format, can be used to switch instruments in a MIDI program or device.

MID files can be played using software instruments, but they do not contain actual audio data, so they are not considered media files.
