Discrete Element Combinatorial Synthesis (D.E.C.S.) Explained

Instead of relying on a single sample per key or a series of static samples which switch based on velocity, D.E.C.S-based instruments have been processed using resynthesis to separate their core components into different elements which are then re-combined on playback. The end result is a much greater level of realism and a far more deeply detailed response to the player's performance.

For example- A recording of a drum can be processed so as to create two independent files, one containing only the sound of the stick impacting the skin/head of the drum, while the other contains the sound of the drum shell resonating from the impact.

By varying the levels of these two components based on velocity or another performance controller, the user can experience a very life-like simulation of a real drum.

The technique also allows for wildly new sounds to be created through the mixing and matching of various components, using different tunings for each component and more.
