Files with a MID extension encode MIDI data into a standard computer format. MIDI (Musical Instrument Digital Interface) is a standard describing protocols and connector interfaces for digital recording of musical instruments. MID files do not contain musical data per sec, instead they contain a code indicating which musical instrument is playing, and the exact note to be played in time sequence. The data also includes volume information for each note. Other controller information may also be contained like sustain pedal data.
The MID file is broken into chunks including Header, Track. The Track chunk includes the MIDI Event Command, or the musical note to be played.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .MID file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .MID file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .MID file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .MID extension. Directly on this website you can find a solution of the most common problem with the .MID file – that you do not have on your computer the appropriate program to open the file.
