Ok in the dos days, when you had a 3 character limit for file extensions, but many other Midi developers , have stuck with the .mid format for compatabilities sake. This does inherit problems, same as Web technology , treat a .Htm & a .Html file differently.
Standard MIDI Files (SMF) contain sounds events that indicate the notes and instruments in a musical performance, but do not include the digital waveform of the audio.They usually have the extension .mid or .midi.To play a MIDI file, software has to synthesize the music, which usually requires reading digital samples of musical instruments from a large file.
.midi To .mid
The scope of this article, however, will mainly focus on the usage of MIDI in computer systems for playback of files that contain MIDI data. These files usually come with the .mid extension, and were hugely popular in the golden days of multimedia computing to share music. In professional music composition/arrangement, it still plays a vital role.
Without going into the details of what the format is composed of, you just need to understand that a MIDI file eg. foobar.mid does not contain any digital audio data, hence no "PCM stream". It is a common misconception that MIDI is a sound file format, and as such you usually see people complaining that music players like Amarok cannot play the file. Here is a very beginner-friendly outline of what a MIDI/MID file contains:
Do your files have the ".midi" extension? VOCALOID4 Editor cannot open files with the ".midi" extension. Change the extension of your standard MIDI files (SMFs) to ".mid". In addition, if your files contain system exclusive (SysEx) data, VOCALOID4 Editor may not be able to recognize and load those files correctly.
MIDI playback was introduced from Audacity 2.2.0. MIDI files can be imported as Note Tracks, which support cut-and-paste editing, and exporting in MIDI (.mid) or Allegro (.gro) formats. Conversion from MIDI to audio formats, and from audio formats to MIDI is not yet supported.

The attributes .midiProgram and .midiChannel on Instrumentobjects are 0-indexed, just as they need to be in the written binary .mid.However, as a convenience, MidiEvent.channel is 1-indexed. Noanalogous convenience is provided for program change data.
These are pygame events (pygame.eventpygame module for interacting with events and queues) reserved for midi use. TheMIDIIN event is used by pygame.midi.midis2events()converts midi events to pygame events when convertingmidi events to pygame events.
Initializes the pygame.midipygame module for interacting with midi input and output. module. Must be called before using thepygame.midipygame module for interacting with midi input and output. module.
Uninitializes the pygame.midipygame module for interacting with midi input and output. module. If pygame.midi.init()initialize the midi module wascalled to initialize the pygame.midipygame module for interacting with midi input and output. module, then this function willbe called automatically when your program exits. 2ff7e9595c
