Velocity Split

A specific type of keyboard zoning or layering where two or more different sounds can be played according to how hard notes are struck on the keyboard. This is measured as velocity, or the time it take for the key to move from the up position to the down position. Velocity splits are used in many different ways, one of which is to make more realistic acoustic instrument sounds. A piano multi-sample, for example, may be made up not only of different samples across the keyboard range, but different samples that trigger at different key velocities, thereby recreating a piano sound that responds to dynamics much more accurately.
