What is a MID file?

File with a .MID extension contains attributes of music data, enabling playing sounds – their order, volume, length and type, it may also contain elements of data needed of a device controller. It is a standard format for many programs utilised for creation and mixing or music devices storing or playing sound compliant with the Music Instrument Digital Interface software.

MID files usually contain the attributes of music data themselves instead of the music, thanks to which they can be played with different instruments, programs or tools which can interpret the data. They can be also used to change the instruments on the MIDI device or information on its configuration.

More information about MID file

MID (short for Musical Instrument Digital Interface) is a native format for MIDI audio files.

MID files can also hold information about device controllers.

MID guide files

As MID files don’t store actual audio data, they can be seen as a ‘instruction’ files on how each note sould be genereated by audio device or media player. MID files can be used by various musical instruments given that the instrument is capable of reading MID data correctly. MID offers advantages such as succintness, ease of editing, and multi-instrument support.

MID file’s compact size

MID files are smaller in size than MP3 or WAV files as they don’t hold any audio data. MID files are thus ideal format for exchanging music information between apps or distributing it over the internet, especially over bandwith-limited connections.

Technical information

MID format has two versions: Type 0 and Type 1. Type 0 is used for single channel data, while Type 1 for multi-channel data. MID connection can carry up to 16 independent channels numbered 1 to 16.

How to open MID files

If you cannot open the MID file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports MID among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the MID file can be found in the table. Now just download and install the appropriate application.

Possible problems with the MID format files

The inability to open and operate the MID file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the MIDI Audio Format file. Below is a list of possible problems.

  • Corruption of a MID file which is being opened
  • Incorrect links to the MID file in registry entries.
  • Accidental deletion of the description of the MID from the Windows registry
  • Incomplete installation of an application that supports the MID format
  • The MID file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the MID file.
  • Drivers of equipment used by the computer to open a MID file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the MID file should operate with your programs without any problem. If the problem with the MID file has not been solved, it may be due to the fact that in this case there is also another rare problem with the MID file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.MID) you have two ways to do it. The first and the easiest one is to right-click on the selected MID file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the MID file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Many files contain only simple text data. It is possible that while opening unknown files (e.g. MID) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
