Opening MID files

Have a problem opening a .MID file? We collect information about file formats and can explain what MID files are. Additionally we recommend software suitable for opening or converting such files.

What is the .MID file type?

The .mid extension is primarily bound up with the MIDI Sequence (MID) file type and format. MIDI stands for Musical Instrument Digital Interface, and denotes a standard way to interconnect musical appliances such as electronic keyboards, drum machines and other devices between each other and connect them to a computer or sequencer.

MIDI sets up a number of channels (usually, 16 with channel 10 reserved for percussion), each of which has or may have an instrument assigned to it. MIDI channels are used to transmit MIDI messages—digital instructions on what note should be played on which channel, with what effects, etc.

A .mid file is a musical composition recorded as MIDI sequence. MID files are usually quite small in size due to the fact that they do not contain any waveform data, just MIDI messages.

MID musical files can be opened and played with the majority of current media players as well as software/hardware MIDI sequencers. Besides, there are tools to convert .mid files into .wav or .mp3. Overall quality and even instrument sound can be quite different when the same .mid file is played on different computers or with different software.

Alternatively, the .mid extension also serves to denote the MapInfo Data File (MID) file type and format. MapInfo is a well-established GIS (Geographical Information System) by Pitney Bowes Software. MapInfo .mid files are auxiliary data files used together with text-based .mif (MapInfo Interchange Format) files.
