prologue Key Features
•
The prologue is a keyboardist-oriented analog synthesizer featuring the best of
Korg’s expertise.
•
Redesignedandrenedanalogcircuitry.Theprologue-16andtheprologue-8pro-
vide respectively 16 and 8 analog voices.
•
Each voice includes a MULTI ENGINE providing a noise generator, a VPM oscilla-
tor, and the possibility to load user programmed oscillators.
•
Equippedwithhighqualitydigitaleects(MODULATION,REVERB,DELAY).
•
Canbeusedasatwotimbresynthesizer,insplit,crossfade,orlayerconguration.
•
Anewlydesignedanalogeect(L.F.COMP.)providesaboostandcompressionin
the low frequency band for a powerful sound (only on prologue-16).
•
500 program locations (250 loaded with factory presets) can be recalled instantly,
and used to store programs.
•
Provides multiple ways to sort and search through programs.
•
Real-time oscilloscope provides visual feedback of parameter changes.
•
Sync In and Sync Out jacks allow you to expand your session setup.

Playing Programs
Selecting and Playing a Program
The prologue has 500 program locations of which 250 are preloaded with factory
presets.Thepresetprogramsareassignedtotherst250 locations and are organized
into sound categories for easy selection. The remaining locations contain the initial-
ization program that can be used as a starting point when creating user programs.
1. Enter the Play mode.
When the prologue is turned on, it will automatically enter the Play mode.
InthePlaymode,verifythattheEDITMODEbuononthefrontpanelareunlit.
2. Turn the PROGRAM/VALUE knob to select a Program.
ThedisplaywillindicatetheProgramnameandnumber.Referto“Program
List”(p.72)fordetails.
TIP In addition to showing Program name and number, the display can also
be used as an oscilloscope, to show the electrical signals created by the
waveform of the sound.
3. Play the keyboard and use the controls on the front panel, such as the OC-
TAVE buons or the wheel.
TheOCTAVEbuons on the left can be used to transpose the
sound within a range of -2 to +2 octaves.
Move the pitch bend wheel up and down to change the pitch, and
move the modulation wheel up and down to change the assigned
parameters.

Using the arpeggiator
The Korg prologue includes an arpeggiator function, which automatically plays pro-
grams in patterns based on the keys you press.
Performing with the arpeggiator
1. In Play mode, press the ARPEGGIATOR ON/LATCH buon.
Thearpeggiatorwillturnon,andtheON/LATCHbuonwilllight.

Creating Sounds
Editing a program means changing the Program’s parameters to alter its sound.
There are two way to create sounds on the prologue.
•
Select an existing Program that’s close to the sound you want, and edit that Pro-
gram’s parameters to achieve your own custom sound.
•
YoucanalsoinitializealltheProgramparameterstocreateyourownsoundfrom
scratch.
Editing an Existing Program
1. In Program mode, select the Program that you want to use as a starting point.
2. Use the knobs and switches on the front panel.
TakeamomenttoconsiderthedierencesbetweenthecurrentProgramandthe
sound you have in mind, and use the front panel controls to edit the necessary
parameters.
TIP Fordetailsonhowthepitch,sound,andvolumechangewhenusingthe
knobsandswitches,referto“BasicParameterEditing”(p.20).
We recommend that you save the Program on the prologue after editing
thesound.Anyeditsthatyoumakewillbelostifyouturnothepower

Saving a Program
We recommend that you save your Program on the prologue after editing the sound.
Anyeditsthatyoumaketothecurrentprogramwillbelostifyouturno
thepowerorrecalladierentprogrambeforesaving.
1. Edit the program in Play mode.
Fordetails,referto“BasicParameterEditing”(p.20).
2. Press the WRITE buon; the prologue will enter the Write standby mode, and
the WRITE buon will blink.
Themessage“Wheretowrite?”willappearinthedisplay.
3. Turn the PROGRAM/VALUE knob to select the Program number where your
new sound will be saved.
TIP PresstheEXITbuontocanceltheoperation.
4. Press the WRITE buon once more.
TheProgramwillbesavedininternalmemory,andthemessage“Complete”
will appear in the display.
NeverturnothepowerwhileProgramsarebeingsaved.Doingsomay
destroy the internal data.

Basic Parameter Editing
In this section, we’ll explain the basic parameters that make up a program.
The basic parameters are assigned to the knobs and switches on the front panel.

sizer engine, and the prologue-8 features a 8-voice
analog synthesizer engine. The Voice mode func-
