MAJOR FEATURES
A completely new kind of MIDI voice
| processor using a new high speed
voice processor LSI chip. Enables
vocoder, polyphonic harmonize, and oth-
er highly useful effects.
In the vocoder mode, this takes the
) tonal elements of the audio input sig-
nal that are vital to voice recognition,
these are the consonants and vowel for-
- Mants, and reproduces these speech
characteristics at the pitch produced by
playing a MIDI keyboard.
Unlike the analog vocoders of the past,
the DVP-1 delivers clear, lucid sound
quality, thanks to its digital processing
technique.
A number of timbre parameter controls
enable adjustment of the sound to obtain
a variety of effecis such as female
chorus, male chorus, electronic voice,
and so on.
The internal wave mode produces
vocoder-like effects based on internally
stored waveforms, without any external
input.

the amount of pitch shift of the har-

to one octave above and below the pitch
of the input signal. Polyphonic production
of up to five notes at once is possible.
This “polyphonic harmonized” sound is
completely new and different, offering an
exciting new sonic palette to the musi-
cian.
There is even a “chord memory” function
that lets you produce harmonies without
connecting a MIDI keyboard.

IMPORTANT PRECAUTIONS
MPLACE OF USE
Do not use this unit for long periods of time where it is exposed to:
e direct sunlight.
® high temperature or humidity.
e sand or dust.
BPOWER SUPPLY
e Use only with rated AC voltage. If you will be using this unit in an area
having a different voltage, be sure to use a proper voltage converter.
® To assure highest sound quality, avoid connecting many units to the
same outlet via extension cords, etc.
HINTERFERENCE
This unit uses microcomputer circuitry. Like all such devices it is subject to
interference from nearby electrical devices like fluorescent lamps, appli-
ances with motors, and so on. If operation becomes erratic or unpredicta-
bie, or if there is no response when you press a button on the unit, then in-
terference may be the cause. If this occurs, try turning off the power, then
turning it back on again. This resets (or initializes) the microcomputer chip.
MHANDLE WITH CARE
All controls are designed to provide positive operation with a gentle touch.
Do not use force.
MCLEANING |
If necessary, wipe the exterior of this unit with a soft dry cloth. Never use
volatile cleaning agents such as benzine, alcohol, or flammable polishes.
EKEEP THIS MANUAL
For future reference, please store this manual in a safe place.
NBACKUP BATTERY
The DVP-1 has an internal backup battery that protects memory contents
when the power is turned off. This battery lasts for about five years. After
five years please consult your Korg service center of dealer to have the
battery replaced.

I Parameters and Values
H Parameters are the factors that affect aspects of the
sound such as pitch and timbre. Parameters also de-
termine reception of MIDI messages.
Each parameter has several possible values. The
combination of parameter values creates particular
effects.
M The available parameters and range of values are Chorus parameters
shown on the parameter list on the top of the DVP-1.
For example, to change chorus intensity, you select CHORUS 7

PARAMETER LIST
(Parameters 14, 15, 16 have no effect on
the internal wave mode.
Parameter 21 cannot be used with the
vocoder mode.)
MB Parameters not used with a particular mode can not
be selected or edited in that mode.
Example: If the vocoder mode has been selected
then you cannot select or edit the “51 KEY NOTE”
parameter of harmonize mode.
However, parameters 71-74 and 81-84 (the
chorus, unison, gate, and MIDI parameters) are al-
ways accessible for editing regardless of the current

4.MIDI Indicator and MIDI Reset Function
EN MIDI Indicator
M The front panel MIDI indicator illuminates when a
valid channel voice message is received. This lets
you check whether a connected MIDI keyboard is
controlling the DVP-1 or not.
If you play the keyboard and the MIDI indicator does
not illuminate then you may suspect that there is
something wrong with the MIDI connection or the
sending and receiving channels do not match (if
OMNI is off) or the key window bottom and top
parameter values are not appropriate.
Check the connection and parameter settings if the
MIDI indicator does not light up when it should.
MIDI Reset Function
NM Sometimes interference may cause erratic MIDI
operation. You may get no sound when you should
get a sound: the sound may not stop when it should,
or pitch bends and modulation may not be released
when they should.
In cases like these, press the WRITE key to reset the
MIDI circuitry.
The WRITE switch should be set to the DISABLE
position when using the WRITE key to reset MIDI.
Otherwise you will enter the write mode.

VOCODER MODE AND
INTERNAL WAVE MODE
|.Operation of Vocoder Mode and
Internal Wave Mode
E Like the sound of a musical instrument, human
speech has elements of pitch and timbre. It is mainly
through the fluctuations in timbre over time that we
understand the contents of speech.
№ п the vocoder mode it is these elements of timbre
that are extracted from the input signal and used to
control the quality of the sound, while the pitch is
determined by notes played on a MIDI keyboard.
H In the internal wave mode the DVP-1 uses internally
stored waveforms instead of an external input. Other-
wise operation is the same in the vocoder mode.
B Use the mode keys to select the desired mode.
E Up to five notes can be sounded at once in the
vocoder and internal wave modes. (Four notes at
once if chorus is on.) Notes can be sounded over a
five octave pitch range of C1 through C6. (For details,
refer to the section on valid note number range.)

Shifts the formant frequency (vocal passage resonance
frequency), thereby changing the timbre of the vowel.
Consonants and vowels characterize the
sounds of speech. The vowels are control-
led by the shape of the vocal passage. The
timbre of vowel sounds is determined by
their emphasized frequency zones called
“formants.” |
Parameters 11, 12, and 13 let you adjust
the formants, and hence the variations in
timbre, to suit your needs.

Normally, consonants are quieter than
vowels and have a larger high frequency
component. Therefore a frequency thresh-
old and volume threshold can be used to
distinguish vowels from consonants.
These parameters are not used in the inter-

Your MIDI keyboard’s joy stick or modulation wheel
(or related device) can be used to control vibrato and
tremolo intensity if operation of these devices causes
control No.1 and control No.2 “control change mes-
sages” to be sent via MIDI. Control No.1 determines
vibrato intensity while control No.2 controls tremolo
intensity.
Even if the “43 PITCH” and “44 DCA” parameter
values are set to “2”, you can add tremolo by using
these MIDI controls. Even if the “42 DELAY” pa-
rameter is set for a long delay time, vibrato or
tremolo will occur immediately if they are controlled
via these MIDI control messages.
The frequency of the effect depends on the DVP-1's
“41 FREQUENCY” parameter value so vibrato and
tremolo speed remain the same regardiess of wheth-
er you are using these MID! control messages or us-
ing internal control. To use MIDI control for vibrato
and tremolo you must have the “84 ENABLE” pa-
rameter set to “2” (ALL). (See page 19 “ENABLE”)
Example: Modulation intensity (depth) control using
the joy stick on the POLY-800, DW-6000, or
DW-8000.

ter.
When this parameter is on (value / ) an upward pitch

In the vocoder and internal wave modes,
pitch and tone color can be changed by
MIDI pitch bender messages generated by
using the connected MIDI keyboard's joy
stick or pitch bend wheel.
The parameters in this section are related
to this MIDI pitch bender message control
capability.
To use MIDI pitch bend control you must
have the DVP-1’s “84 ENABLE” parameter

EX TIME (Portamento Time)
Portamento is a gradual and continuous change in pitch
from one note to the next. The value of this parameter
determines how long it takes for the pitch to change.
When you release a key this effect holds the note as if
you had kept the key depressed. This parameter’s value
determines whether the hold effect is on or off.
In the DVP-1’s vocoder and internal wave-
form modes you can obtain gradual pitch
transitions from note to note when you
play one key after another on the MIDI
keyboard. This effect is called “portamen-
to.” This section also allows notes to be
“held” after you release keys on the key-
board. These “hold” and “portamento” ef-
fects are controlled by the parameters in
this section. |
A foot switch (Korg PS-1 or equivalent)
connected to the rear panel portamento
jack can be used to turn the hold and por-
tamento effects on and off. (MIDI control is
also possible.) If foot switch control is used
(whether it be an actual switch or a MIDI
message), the effect turns on only while
the foot switch is depressed. Of course,
the parameters must be set so that you can
obtain the desired effecis. |

VOCODER MODE AND INTERNAL WAVE MODE
A MIDI control change message (generated by a MIDI
keyboard switch or pedal) from a connected MIDI
keyboard can control on/off switching of the por-
tamento and hold effect on the DVP-1.
As when using a foot switch connected to the DVP-1
rear panel portamento jack, you must set parameters
47 and 48 to obtain the effects that you want.
When using MIDI control for the portamento and hold
effects, it is necessary to set the “84 ENABLE”
parameter value to “7” (ALL). (For details, refer to the
“84 ENABLE” parameter.)
Also, the “88 FOOT SWITCH” parameter value must
be set to a value other than “7” (DISABLE). (For
details, refer to the “88 FOOT SWITCH” parameter.)
MIDI Control of Portamento & Hold
Example: Using the DW-6000 or DW-8000 for control
of DVP-1 portamento and hold effects.

ROG. UP PORTAMENTO DAMPER
When portamento is operated on the DW-6000 or

HARMONIZE MODE
|. Harmonize Mode Operation
M The Harmonize mode takes the input signal pitch and
raises it or lowers it by a particular amount to produce
its output. When the input signal pitch changes, the
output signal pitch changes too.
Pitch can be changed over a range of one octave
above or below the input signal pitch. The amount of
pitch change can be specified in semitone steps
within this range.
B The Harmonize mode has five harmonize units so it
can generate chords of up to five notes. (Only four
notes at once are possible when the chorus effect is
turned on.)
M There are two main ways to use the Harmonize
mode. You can use a MIDI keyboard to specify, in
real time, the amount of pitch change and “output
on/off.”
Or you can set the CHORD parameters, ahead of
time, to determine the amount of pitch change and
“output on/off.”
Example: To raise input signal pitch by five degrees.

The Key Change Function
| The key change function is effective when playing
| chords on the keyboard. When the key change func-
| tion is on, then the key note set in the “51 KEY
NOTE” parameter becomes ineffective. Instead, the
| first note that you play becomes the key note (thereby
| also changing the value of the “51 KEY NOTE”
| parameter). The input signal pitch is then shifted by
the amounts determined by the relationships be-
| tween other notes played and the key note itself. This
| creates a chord that includes the original input note
| pitch. -
|
|
|
|
|
|
|
This lets you set the key note and its surrounding
“valid range” (an octave above and below the key
note) to wherever you are playing on the keyboard.
You can then play chords freely within this new range
without considerations of “foldback.” (However, the
first note played (the one which becomes the key
note) must be within the range of C1 to C6). Keys
played outside of this range will not cause the key
note to change.
|
EE CHORD MEMORY
When using a MIDI keyboard for harmonize mode pitch
control, sound will be produced only while keys are
pressed if the value of this parameter is ““”.
However, if you set this parameter's value to “/”, then
the keys will be “held” after you have released them
and sound will continue to be produced. (In this case,
the CHORD parameter (numbers 54 — 58) pitch change
values are set by the relationships between the key note
and the notes played above and below it.)
Moreover, if this value is set to “!”, then the CHORD
parameters (beginning with number 54), can be used to
set the amount of pitch change. Output will then be pro-
duced according to those values and a MIDI keyboard
will not be needed. (Refer to following section on the
CHORD parameters.)

HARMONIZE MODE
CHORD
With parameter “53 CHORD MEMORY” set
to “/” (enable), you can use these
“CHORD” parameters to control the
amount of pitch change, if any, produced
by each of the five harmonize modules. In
this way, you can produce polyphonic out-
put from monophonic input without need-
ing to use a MIDI keyboard.
There are five CHORD parameters from
“NOTE 1” to “NOTE 5” which can be set in
semitone increments over a +1-octave
range.
To set the values (amount of pitch change)
for these parameters you car use the
VALUE EDITOR controls (DOWN and UP
keys, etc.). Or you can set parameter “53
CHORD MEMORY” to a value of “/” and
use a MIDI keyboard.
Furthermore, if “53 CHORD MEMORY” is
set to “/” and a chord relationship is set up
in the CHORD parameter values, then you
can store that chord relationship in the pro-
grammer memory along with other pa-
rameter values. This procedure is de-
scribed in the later section on the “pro-
gram write function.” (This capability is
called “chord memory.”)
HARMONIZE MODE
EEE NOTE 1 ~ NOTE 5
Each of these determines whether its harmonize unit is
on or off and, if on, what amount and what direction of
pitch change it will produce.
If the value display shows “--”, the harmonize unit is off
and will produce no output.
At values other than “--”” the harmonize unit is on and its
particular value and sign (- or no sign) refers to the
amount and direction of pitch change produced (that is,
the number of semitones above or below input pitch).
Numbers preceded by the “-” sign refer to a pitch differ-
ence below the input signal pitch. Otherwise the pitch
difference is upward.
These values can be set by playing a MIDI keyboard. In
this case the parameter number is determined by the
order in which the keys are played, while the value is
determined by the relationship (number of semitones)
above or below the key note.
If the chorus effect is on, then only parameters 54
through 57 are effective. If “unison” is on, then only
parameter 54 is effective. (Refer to sections on chorus
and unison, respectively.)

PITCH SHIFT MODE
Pitch Shift Mode Operation
B The Pitch Shift mode works like a conventional har-
monize module, raising or lowering the pitch of the in-
put signal by an amount specified by the parameter
values. Pitch can be changed by any amount from
— 1200 cents to + 1299 cents in 1-cent steps. (A cent
is a pitch measurement unit. One semitone is 100
cents. One octave is 1200 cents.)
M This can be used to “fatten” the sound. You can raise
or lower the pitch by a small amount, mixing the de-
tuned result back in with the input.
Or, feedback can be prevented by changing vocal
pitch very slightly and outputting only the pitch
shifted result. (Direct output level is reduced to zero.)
Alternatively, you can set the amount of Pitch Shift to
“0” and use the chorus and gate effects by them-
selves. (Refer to the sections on chorus and gate
functions for details.)
When producing conventional pitch shift effects, only
one of the five harmonize units is used. However, the
“74 DETUNE” parameter can enable all units to be
detuned by small but differing amounts, thereby
yielding an even fatter sound. (See parameters for
unison control.)

mode.

OTHER FUNCTIONS
IE EFFECT
The DVP-1 outputs a mixture of sound with and without
the chorus effect. This parameter’s value determines
the mixture ratio of these two sounds.
). Unison
NM The vocoder mode, internal wave mode, and har-
monize mode use five units to enable 5-voice poly-
phonic output. If you turn on the Unison mode then
only the first unit will operate and the output will
become monophonic. (This is true as long as the
detune parameter value is “5”.) If you set the Unison
mode's DETUNE parameter to a value from “:” to
“3” then each of the five units will gain a slightly dif-
ferent detuning and all units will sound together,
creating a fat or layered sound.
(The Unison mode is monophonic. Only the first of
the Harmonize mode’s CHORD parameters can be
used to specify the output pitch change. Parameters
“55 NOTE 2" through “58 NOTE 5” have no effect.)
MM To use the unison function, press the UNISON key on
the front panel so that its LED illuminated. (To turn
off, press again.)
(Amount of signal
Value Chorus volume ' without chorus)
! Low (High)
7 High (Low)
If unison is off:
Units are used according to the number of keys placed.
If unison is on (and detune is at “0”):
Only first unit is used.
If detune is set to 1, 2 or 3 when unison is on:
All units sound together when one
key is played. Each unit has a
slightly different pitch.

Unison parameters.
74 DETUNE
In DETUNE
At a value of “7”, only the first unit is used. At values
other than “7”, all five units are used together. The
larger the value, the greater the pitch differences be-
tween units.
OTHER FUNCTIONS
Unison affects the Vocoder mode, Internal
Wave mode, and Harmonize mode. In
these modes, the detune parameter be-
comes effective when the UNISON key is
on, allowing each unit to produce a slightly
different pitch, thereby fattening the sound.
(In the Pitch Shift mode, this parameter can
be used regardless of whether the unison
effect is on or off.)
Value Detuning
Li Only first unit is used.
! All five units are used with small
pitch differences.

All five units are used with large
pitch differences.

This sets the threshold volume level for the input. If input
falls below this value then the gate attenuates the output
according to the decay time set by the “82 DECAY”
parameter.
The gate opens when the input signal rises above the
threshold. The higher the threshold parameter value,
the higher the input signal must rise in volume before it

4 Freeze
EN Freeze Operation
H To use the Freeze function, connect a foot switch
(PS-1 or equivalent) to the rear panel FREEZE jack.
№ When the foot switch is depressed, the DVP-1 takes
part of the waveform and keeps repeating that cycle,
using it instead of the external input, until the foot
switch is turned off.
With this Freeze function, you can capture a brief in-
put, retaining that sound for as long as you like.
№ The Freeze function can be used in the Vocoder
made, Harmonize mode, and Pitch Shift mode. De-
pending on freeze foot switch operation timing, noise
may appear in the output. Try pressing the foot switch
again if this occurs.

E] Communications between a Computer and the DVP-1
M The DVP-1 can send and receive the following kinds of information via system exclusive messages.
Sending
DEVICE ID : Identifies equipment. Sent when a DEVICE ID REQUEST is received.
WRITE COMPLETED : Indicates a successful program write. Sent in response to a WRITE REQUEST.
WRITE ERROR : Indicates program write failure due to front panel write switch being set to DISABLE.
Sent in response to a WRITE REQUEST.
DATA SAVE (DATA DUMP) : The program data. Sent in response to a DATA SAVE REQUEST.
Receiving
DEVICE ID REQUEST : À request to send the DEVICE ID.
WRITE REQUEST : Request to write loaded program data to the DVP-1 programmer.
DATA SAVE REQUEST : A command to send program data.
DATA LOAD (DATA DUMP) : The program data to be loaded to the DVP-1.
PARAMETER CHANGE : Data which changes parameter values.
M These system exclusive messages can be used for data transmission between the DVP-1 and a computer equipped
with a MIDI interface and software that handles these system exclusive messages.
M Setup is shown here:
E All DVP-1 exclusive messages use a “channel” determined by the value of parameter number 83. The channel set
on the DVP-1 must match the channel used by the computer. Otherwise messages will be ignored. (This channel is
for exclusive messages only and has no effect on omni mode channel mode messages.)
If these channels are used then several DVP-1 units can be used in a system and program control can be in-
dependently performed for each.
