Kurzweil K2000

The Kurzweil K2000 is a digital synthesizer and music work station produced by Kurzweil Music Systems between 1990 and 2003 in a variety of standard configurations, including rack-mountable versions and models that came with 16-bit user sampling.

The K2000 features a complex digital synthesis architecture dubbed V.A.S.T., which stands for "Variable Architecture Synthesis Technology", Kurzweil's marketing term for the digital signal processing (DSP) sound processing system used in the K2000 and other members of its K2xxx series.

Variable Architecture Synthesis Technology (V.A.S.T.)

Summary

V.A.S.T stands for variable-architecture synthesis technology. It is variable in that the user can select different signal paths, which contain different DSP functions, for use in creating and shaping a sound. V.A.S.T. also includes an extensive modulation system, similar in concept to that of analog modular synthesizers. A wide array of modulation sources can be assigned to various parameters within a signal path, and modulation sources can be combined to create new modulation sources.
