Kurzweil K2600 - VAST Synthesis; KB3 Tone Wheel Emulation

Introduction
VAST Synthesis
1-3
An optional sampling feature is available, allowing you to make your own mono or stereo
samples using analog or digital inputs. With the sampling option, you can also use Live mode,
which enables you to take an input signal (at the analog sampling input), and route it through
the K2600Õs VAST algorithmsÑso you can apply Kurzweil DSP and effects to any sound The
sampling option also gives you digital audio output (stereo optical or unbalanced stereo XLR).
ThereÕs also the digital input/output (I/O) option, which provides eight channels for digital
audio input and output (as well as a stereo digital output).
And, of course, thereÕs the incomparable Kurzweil sound. The K2600 comes to you with over
400 programs (called patches, presets, voices, etc. on other synths)Ñ238 in ROM and 200 more
in RAM. There are also about 200 multi-zone performance setups. Many of these setups use note
triggers to play factory-recorded songs that provide grooves and arpeggiation that make great
templates for performance or recording.
VAST Synthesis
Variable Architecture Synthesis Technology gives the K2600 its unprecedented ßexibility. While
many other synthesizers offer a Þxed set of DSP tools (typically Þltering, pitch, and amplitude
modulation) the K2600Õs Variable Architecture lets you arrange a combination of any Þve DSP
functions from a long list of choices. The functions you choose deÞne the type of synthesis you
use.
Each layer of every program has its own DSP architecture, which 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
ßexible, truly vast collection of tools for sound creation and modiÞcation. When youÕre ready to
jump in and start creating and editing programs, turn to Chapter 6.
KB3 Tone Wheel Emulation
In addition to VAST synthesis, the K2600 offers many oscillator-based programs that give you
the classic sound of tone-wheel organs like the Hammond B 3ª. KB3 mode, as we call it, is
completely independent of VAST, and has its own set of editing procedures. YouÕll Þnd details in
Chapter 6.
