ABSTRACT
A digital audio workstation (DAW) is a computer program that records, edits and mixes both audio and MIDI. In 1986, German company C-Lab released an innovative MIDI sequencer for Atari computers under the name “Notator”. With MIDI, real-time information can be sent, for example from a master keyboard to a synth. Once a MIDI part is recorded in the DAW, notes can be edited and parts can be copied. After recording a MIDI arrangement, it can be transposed or its tempo can be changed. Since computers work with USB connections, the MIDI protocol has been ported to USB. Working with MIDI-over-USB is self-explanatory: just connect a USB keyboard to the computer, and it will usually be recognized by the DAW automatically. Apart from note information, MIDI can transmit other data as well. 127 MIDI controllers are defined in the MIDI specification.
