FEATURES OF THE KORG DW-8000
1
A newkind of 8-voice programmable
polyphonic synthesizer featuring an
advanced Digital Waveform Genera-
tor System (DWGS).
The DWGShas sixteen digitally encoded
waveformsstored in four 256 kilobit ROM
chips. These waveforms are digitally en-
coded samples of actual acoustic instru•
ments recreated by additive synthesis
techniques
to enable more realistic
sound synthesis. (Thesixteenwaveforms
also include simple sawtooth and pulse
waveforms such as
"~, n .. " and "I\J"
which are found in conventional analog
synthesizers.)
2
Uses two Digital Oscillators, analog
noise generator, and VCF and VCA
modules for sound synthesis. You
can enjoy the uniqueness ofdigital sound
plus quick and logical sound synthesis as
in analog -control.
3
The DW-8000 features a keyboard
with Initial Touch (key velocity) and
After Touch (channel pressure) func-
tions. These functions give you real-time
control
at your fingertips of output
volume, tone color, and pitch modulation
for finely-controlled, dynamic playing.
.. ,

Thank you and congratulations on your choice of the
Korg DW-8000. To obtain optimum performance
from this advanced digital synthesizer? please read
this manual carefully before using this synthesizer.
4
A programmable digital delay is in-
cluded to store clear stereo effects
(Chorus, Doubling, Short Delay, and
long Delay) for each of 64 tone colors in
the programmer.
5
Built-in Arpeggiator with MIDI control
capabilities and Assign mode, which
can function as 64-note sequencer.
6
Auto Bend is included for more real-
istic synthesis of human voice and
brass sounds.
7
Polyphonic Portamento can be con-
trolled by footswitch.
8
Key Assign mode provides two poly-
phonic modes and two unison
modes, which are effective for play-
ing solo
or bassparts or using Portamen-
to.
9
MIDI equipped for full interfacing with
other MIDI equipped devices, includ-
ing synthesizers, sequencers, and
personal computers.

IMPORTANT SAFETY PRECAUTIONS
■ LO CATION
To avoid malfunction do not usethis un.it in the followi ng locationsfor long
periods of time:
• In direct sunlight.
• Exposed
to extremes of temperature or humidity.
• In sandy or dusty places.
■ POWER SUPPLY
• Use on ly with rated AC voltage. If you will be using this unit in a country
having a different voltage. be sure
to obtain the proper transformer to
convert to rated voltage.
• To
he lp prevent noise and degraded sound quality, avoid using t he
sameoutlet asotherequipmentorbranchingoffextension cordsshared
by other equipment.
■ INPUT/OUTPUT JACKS AND CONNECTION CORDS
Be sure to us e standard "guitar" cables with phone plugs, such as the
cable suppliedwith this instrument, for input and outputconnectionsto the
rear panel of the DW-8000. Never insert any other kind of plug into these
jacks.
■ PREVENTING ELECTRICAL INTERFERENCE
As a microprocessor based device, the DW-8000 is extremely flexible 1in
operation, yet may possibly perform erratically
if exposed to electrical in-
terferencefrom otherelectrical devices and lluoresoentlamps. Avoid oper-
ating the DW-8000 near possible sources of interference.
If somethi ng
seems to be wrong, try turning off th e power, waiting about ten seconds,
then !urni
ng it back on. This resets the computer circuits to their initial
state so performance should return to
no rmal.
■ HANDLE GENTLY
Knobsand switchesare designed to provide positiveoperationwith a li ght
touch. Excessive force may cause damage.
■ MAINTENANCE
Wipe the exterior with a soft, dry cloth. Never use paint thinner, benzene
or other solvents.
■ KEEP THIS MANUAL
Store this manual in a safe place for future reference.
■ MEM ORY BACKUP
•To protect your programmed memo ry contents, the DW -8000 utilizes a
built-in rechargeable backup battery power supply. Battery li
fe is rated
at live years or more, so replacement is recom mend ed after five years ,
Contact your Karg dealer or authori2ed service center at that time.
•
For maximum securi ty , save your sound p rog rams on tape, using the
bu il t-in tape interfacesystem. Then ii memorycontents are accidentally
erased oraltered,youcan simplyloadthedataback into DW-8000 inter-
nal memory in seconds!

The PROGRAMMER section on the front panel is used for this purpose.
1. About Program Numbers. ___ _
The DW-8000 can be store up to 64 different sound pro-
grams in its internal memory. Each of these programs
has a numberfrom
11 through 88(thedigitsOand 9 are
not used). When you want to store a sound, you must
assign
it a program number. When you want to recall
that sound, you select
it by t he same program number.

CREATING SOUNDS How to Make New Sounds
1.sound Synthesis Techniques __ _
D Parameters and Values
Thevariousaspectsofa sound, such as itspitch, tim-
bre and variations in volume, are called "Parame-
ters." To create or change a sound, yo
u, adjust the
vaiues
oi each of these parameters.
On the DW-8000, there are 49 parameters per pro-
gram; each parameter has a number, and each pa-
rameter's value is also represented by a number.
These numbersareshownon the front panel display.
To create or change a sound, you select parameters
and change (or "Edit") their values.
Parameters lor oscillator 1
OSC1
11 OCTAVE
16' 8' 4'
When the DW-8000 stores a sound in memory or
calls it back from memory, it is actually storing and
recalling the values you have given it for
the sound's
various parameters.
All possible parameters and
values are listed in the "parameter
index" chart on
the rightside of the DW-8000 frontpanel. ii"ocreate or
change a sound, you first usethe number keys
to se-
lect a parameter number, then you use the editslider
and up/down keys to change its value.

To create new sounds on the OW-8000, you change
or edit old programs. You do not start with a "blank
slate", There are 64 sounds already in memory. If
you have a new sound in mind, the easiest approach
is to first selecta sound thatresembles the soundyou
want
to create. Then "edit" (change the selected
sound until you get the sound you want. If you don't
find a similar sound, it doesn't matter; start with any
sound you iike.)
After you finish editing your sound, you s!ore
it in!o
memory. At
this point you can give it a different pro-
gram number (thereby preserving the sound you
startedwith)
or thesame program(therebyerasing or
"overwriting" the old sound).
Selecting a
Program:
Anding a cur-
rent program-
med sound that
resembles the
new one you
wish to create.
Creating
Sounds (Editing):
Changing the
values
of the
parameters that
need
to be
changed
to ob-
tain the desired
SOOl1d.
Writing the
Program to
Memory:
Giving the
S01Jnd a pro-
gram number
and storing it in
memory.

CREATING SOUNDS
-CUTOFF
Th is determines the cutoff frequency of the low-pass
filter. The higherthecutoff frequency, the lesseffect the
filters have on the basic waveforms (since more fre-
quencies are passed).
At the highest value, 63, all harmonics are passed. The
lower the value, the more harmonics are cutoff, so the
sound becomes progressive ly rounder or less bright.
-RESONANCE
Thisemphasizes theharmonicsnearthecutofffrequen-
cy, producing a characteristic peaky or bandpass type
of sound.
The higher the value, the higher the resonance peak
and the more obvious the effect. At or near the max-
im um value 31, the VCFs go into self-oscillation, pro-
duc i ng apure sine wave, which can be u sed as an add i-
tional sound source for special effects. T he pitch of the
VCF tone is affectedbytheCutOff, KeyboardTrack, EG
INT, and MG VC F parameters.
