MIDI (Musical Instrument Digital Interface)
MIDI
MIDI interfaces are a very useful tool for musicians to combine a wide variety of electronic instruments into one file. Essentially, MIDI is a standardized data transfer protocol for communicating various musical instruments, computers, controllers, and other devices. The interface itself appeared back in the 70s, but it still remains one of the main interfaces for working with musical instruments or creating music.
With the help of MIDI, information is encoded about actions that are performed on a musical device - pressing keys, buttons, etc. There is a standard MIDI file - SMF, which is read by all MIDI devices. A separate midi track is a kind of musical score, but at the same time, it contains all the nuances of individual performance. MIDI melodies can be created using special programs similar to sheet music editors.

M4R is the audio format used by Apple in the iTunes application. M4R files are usually ringtones that you can install on your iPhone. At its core, M4R is a regular M4A (MPEG-4) audio file, and the .m4r extension is used to distinguish ringtones from other melodies. Often the maximum length of an M4K ringtone is limited to 40 seconds. If you downloaded such a file from the music store on your iPhone, you will need to convert it to use on other devices.
