In reality, the MIDI files are very small, since the use of the sound card built-in tools for processing of sounds. The problem is that most sound cards do not have any decent sounds to start with, plus no two sound cards sound alike and therefore the results are very irregular. MIDI audio files, as they usually are coming from one of those cheap Casio keyboards. Using MIDI for background music is very likely to make your site seem sloppy. Want to know how to do it anyway? Just add the line to your site and when the page is loaded the file will be done by the robotics control the Auto Start. Although professional sound recording packages can be quite expensive, you can get your feet wet, try one of the obtainable shareware programs.

The Musical Instrument Digital Interface allows music to be recorded or produced by using a data file containing multiple status messages in series whose curriculum and matching note on and note off messages. Instead, digital audio is usually compressed only, using a suitable technique of data compression, and registered. The audio content of such a digital recording can then be restored by decompression of the recorded data and converting the data from a digital-to-analog converter. The method and apparatus of the present invention to selectively and alternatively couples portions of a compressed digital audio file and a MIDI file to a single digital signal processor that decompresses the file either digital audio and implements a MIDI synthesizer. Uncompressed audio and MIDI synthesized music are then connected alternately to two separate buffers. The filling of this buffer are therefore additive mixed and matched by a digital-to-analog converter to an audio output device to create an output with simultaneous digital audio and MIDI synthesized music. A technique and equipment are presented in parallel to output digital audio and MIDI synthesized music using a single digital signal processor.

Virtual instruments are computer-generated sounds that can be played via MIDI. Traditionally, MIDI was used to send music data to hardware devices like keyboards and sound modules, but computers are powerful enough to emulate sound modules. In addition, virtual instruments can be loaded into computer memory to perform all kinds of sounds, instead of connecting the wires to an external device to play MIDI tracks and these tracks can be pooled with the audio tracks to be processed with effects like reverb and chorus and also to have played in perfect synchronization to achieve a professional result sound.
