MIDI – Instruments on your computer
MIDI (abbreviation for "Musical Instrument Digital Interface") is a hard and software protocol that has become the norm in electronic music since the 1980s.
It is used to control sound data transferred from instruments to the computer. The signal is not received by the computer as a sound; only information about velocity of key presses on the instrument, pitches, and sound types are transferred.
The sequencer is used to reconstruct the series of sounds using this information. The control data that is transferred to the computer is then able to be processed by suitable software. A MIDI editor, e.g. the editor included in MAGIX Music Maker or Samplitude Music Studio, makes it easy to work on musical ideas further. When a music project is finished, MIDI data is able to be heard via an analog digital converter ("audio-digital converter" or ADC) on the sound card. The piece of music created with the MIDI editor may be converted into an audio file and converted in the right format with a codec (e.g. MP3).
