In the K2000, a preset configuration of programmable
digital signal processing functions. Each of a
program's layers uses its own algorithm, which
determines the type of synthesis each layer uses to
generate its sound.
A type of distortion which occurs in digitally sampled
sounds when higher pitches (increased sample playback
rates) introduce partials that were not present in the
original sound. These partials mayor may not be
musically useful.
The intensity of a signal, perceived as loudness in
the case of audio signals.
A term used widely in electronics-related fields to
describe a method of representing information, in
which the method of representation resembles the
information itself. Analog synthesizers, for example,
use gradual variations in electrical voltage to create
and modify sounds. The oscillations in voltage are
analogous to the waveforms of the sounds they
generate. Compare digital.
In terms of sound generation, the range of frequencies
within which a device functions. The human ear has a
"bandwidth" of almost 20 KHz (it can distinguish sound
at frequencies from 20 Hz to 20 KHz). The K2000's 20
KHz bandwidth enables it to produce sounds which span
the entire range of human hearing.
There are two types of banks in the K2000's memory:
memory banks, which store and organize the programs
and other objects you create, and Quick Access banks,
where you can store programs and setups for one-button
access while in Quick Access mode.
1/100th of a semi tone. The standard increment for
fine adjustment of pitch.
A device which converts motion into a range of 128
possible values which can modulate a sound source.
The Mod Wheel, a standard volume pedal, and
controllers like Breath and Aftertouch are continuous
controls. Compare switch controls.
Anything which can be used to modify some aspect of a
program's sound. LFOs, envelopes, Mod Wheel messages
(MIDI 01), and FUNs are just a few examples of the
K2000's control sources.
