What is VAST?

What is VAST?
Variable Architecture Synthesis gives the K2500 its unprecedented flexibility. While many other
synthesizers offer a fixed set of DSP tools (typically filtering, pitch, and amplitude modulation)
the K2500's Variable Architecture lets you arrange a combination of any five DSP functions
from a long list of choices. The functions you choose define the type of synthesis you use.
Each layer of every program has its own DSP architecture, what we call an algorithm . Within
each algorithm, you can select from a variety of DSP functions. Each function can be
independently controlled by a variety of sources including LFOs, ASRs, envelopes, a set of
unique programmable functions (FUNs), as well as any MIDI control message. The many
different DSP functions and the wealth of independent control sources give you an extremely
flexible, truly vast collection of tools for sound creation and modification.

How the K2500 Works

The K2500 integrates two MIDI-driven components: a sound engine, and a global effects
processor. The sound engine responds to the MIDI events generated by your MIDI controller
and turns them into sounds that are processed within the variable architecture of the
algorithms. The resulting sound can then be routed through the effects processor and to the
MIX or separate audio outputs.
