Editing a Program

Original sounds can be created by either using an exist-
ing preset program as template, or by starting from
scratch using the Init Program.
Editing Parameters
The basic parameters of the synthesizer are split into
sections on the front panel (VCO, FILTER, etc.). Use the
knobs and switches to adjust the sound to your liking.
Voice Mode Selection
The 16 voices of the prologue-16, and 8 voices of the
prologue-8, can be combined in different ways. Four
voice modes can be selected using the SELECT button.
Depending on the mode, the VOICE MODE DEPTH
knob will have a different effect.
Editing Effects
(EFFECT section, L.F. COMP. section)
Using the MOD EFFECTS switch, modulation ef-
fects like chorus and phaser can be selected. Pushing
the switch up towards the SELECT label, will cycle
through the available effect categories. The SPEED and
DEPTH knobs can be used to adjust each effect.
Using the DELAY/REVERB switch, the delay and
reverb effects can be selected. The TIME and TONE/
FEEDBACK knobs can be used to adjust each effect.
In the case of the prologue-16, the L.F. COMP. switch
can be used to turn the analog boost compressor on
and off. The GAIN knob can be used to adjust the
amount of effect applied.
More editing options are available in EDIT MODE. For
details refer to the Owner's Manual (www.korg.com).

Restoring the Factory settings

You can restore the prologue's preset Programs and
global settings to their original factory-set state at any
time.
1.
Begin with the prologue turned Off.

While holding down the WRITE button and the EXIT
button, turn the prologue On.
"FACTORY RESET" will be indicated in the display.

Never turn off the prologue while data is being
loaded. Doing so might damage the internal data.

Analog Circuitry and Tuning

Tuning Operation
As with all analog instruments, the prologue's circuitry
can drift over time during performance due to changes
in environment and temperature. The prologue pro-
vides an auto-tuning function that automatically tunes
the instrument's analog circuits on demand, to correct
for any analog drift.
1.
Hold down the SHIFT button and press the EXIT
button.
Auto-tuning begins.
During tuning, you will temporarily be unable to
play the instrument.
