12. PATCH 1, 13. PATCH 2, 14. PATCH 3, 15. PATCH 4 — SYNTH
The microKORG provides four Virtual Patch routes that let you create more sophisticated sounds. Each patch lets you select a modulation
"SOURCE" (knob 1) and modulation destination "DEST" (knob 2), and specify the intensity of modulation "MOD INT" (knob 3). By using
various patchings you can create a wide variety of changes in the sound.
For example if you set the modulation source "SOURCE" (knob 1) to LFO2 (
) and set the modulation destination "DEST" (knob 2) to
CutOff (
), and use "MOD INT" (knob 3) to adjust the depth of the effect, LFO2 will create a cyclic change in tone (a "wah" effect).
DEST [Pitch, OSC2 Tune, OSC1
Control 1, Noise Level, CutOff,
Amp, Pan, LFO2 Frequency]
Selects the parameter (destination)
that will be controlled by the modu-
lation.
For example if you select Pitch
(
), modulation will be applied
to the overall pitch of the timbre.
Pitch ( ):

OSC2 Tune ( ): OSC2

OSC1 Control 1 (

OSC1 "CONTROL 1"
Noise Level (

MIXER "NOISE LEVEL"
CutOff ( ): FILTER "CUT-
OFF"
Amp (
): AMP "LEVEL"
Pan ( ): AMP "PAN"
LFO2 Frequency (
):
LFO2 "FREQUENCY"
If LFO "TEMPO SYNC" is ON,
selecting LFO2 Frequency will
have no effect.

EG, AMP EG,
LFO 1, LFO 2, Velocity, KBD Track,
Pitch Bend, MOD.Wheel]
Selects a modulation source.
For example if you select Filter EG
(
), the Filter EG will be the
modulation source.
FILTER EG ( ): FILTER EG
AMP EG (
): AMP EG
LFO 1 (
): LFO 1
LFO 2 ( ): LFO 2
Velocity (
):
Velocity (keyboard playing
strength)
KBD Track ( ):
Keyboard tracking (keyboard posi-
tion)
Keyboard Track operates ac-
cording to the pitch that is con-
trolled by pitch bend, and trans-
pose. It is not affected by pitch
changes produced by vibrato or
Virtual Patch.
Pitch Bend ( ):
PITCH wheel
MOD.Wheel ( ): MOD
wheel
MOD INT [-63...63]
Specifies the depth of the effect pro-
duced by the modulation source.
With a setting of 0, there will be no
modulation.
Virtual Patch
On modular analog synthesizers, the input or output of each module
(oscillator, filter, amp, EG, LFO, and other controllers) was connected
("patched") by a patch cord as desired, allowing you a great deal of
freedom in creating the sound. The Korg MS-20 (which went on sale in
1978) also allowed a limited degree of this type of patching.
The microKORG lets you perform this patching "virtually" (i.e., without
using physical patch cords), so you can assign sources such as EG or LFO
to the most important parameters (destinations).

The Filter EG or Amp EG will vary the pitch of the entire timbre over time.
The Filter EG or Amp EG will vary the pan over time. By setting two patches to "MOD
INT" settings with the opposite (+/-) value you can create more complex panning.
Vibrato will be applied at the LFO1 or LFO2 frequency.
Wah will be applied at the LFO1 or LFO2 frequency .
Tremolo will be applied at the LFO1 or LFO2 frequency.
Auto pan will be applied at the LFO1 or LFO2 frequency.
Velocity (keyboard playing strength) will affect the volume.
Keyboard position will gradually change the pan; lower notes at the left,
and higher notes at the right.
PITCH wheel operations or pitch bend change will move the sound between
left and right.
MOD wheel operations or CC#1 will vary the cutoff frequency.
MOD wheel operations or CC#1 will vary the LFO2 speed.
