Quantization (sound processing)

Quantization is the process by which MIDI events ( digital control statements for a synthetic instrument, MIDI = Digital interface for musical instruments) are shifted as needed on a given by the quantization stage in the musical process.

Thus, the rhythmic deviations from the grid, which are inevitable in natural style of play, to be corrected. Quantization usually based on the beats ( eg quarter - grid, rather unusual, because too coarse ) or common modifications such as triplets ( semiquaver triplets need eg twenty-fourth - height).

This process corrects errors deprived the recording in many cases, the human " groove" (often also called " drive" ), since a musician with his instrument never achieved the precision of a machine. A drummer for example, is every now and then minimally differ from the speed and / or clock, giving the music but only a certain " life " breathes while a machine ( only once ) always 100 % analytically plays through. In addition, many genres call for a specific deviation from the theoretical grid ( notes inégales, swing, groove, Viennese Waltz ).

Some programs, which are used for such work (sequencer ), therefore provide the opportunity to consider these regular modifications of the grid and / or to simulate through intentional, small errors the " groove".
