The R3 provides six Virtual Patch routes that let you create more sophisticated sounds. Each patch lets you select a modulation ("Source") and
modulation destination ("Dest"), and specify the intensity of modulation ("P.Int1"-"P.Int6"). By using various patchings you can create a wide
variety of changes in the sound. For example if you set the modulation source "Source" to LFO2 and set the modulation destination "Dest"
(knob 2) to Cutoff1, and use "P.Int#" (knob ) to adjust the depth of the effect, LFO2 will create a cyclic change in tone (a "wah" effect).
Selects a modulation source.
EG1, EG2, EG3: EG1, EG2, or EG3.
LFO1, LFO2: LFO1 or LFO2.
Velocity: Keyboard velocity (playing dy-
PitchBnd: Pitch bend.
ModWheel: Modulation wheel.
KeyTrack: Keyboard tracking (position).
Keyboard tracking works according to
the pitch as controlled by pitch bend,
transpose, and modulation sequencer.
It does not reflect pitch changes pro-
duced by vibrato or virtual patching.
MIDI1, MIDI2, MIDI3: The function
specified for the Global mode 45. PatchSrc
page parameters "MIDI1," "MIDI2," or
Selects the parameter (destination) that will
be controlled by the modulation. For ex-
ample if you select Tune, modulation will be
applied to the overall pitch of the timbre.
Pitch: The pitch of the entire timbre.

Specifies the depth of the effect produced
by the modulation source.

The EG1 or EG2 will vary the pitch of the entire timbre over time.
The EG1 or EG2 will vary the pan over time. By setting two patches to "MOD INT"
settings with the opposite (+/-) value you can create more complex panning.
LFO 1/LFO 2 ®Tune
Vibrato will be applied at the LFO1 or LFO2 frequency.
LFO 1/LFO 2 ®CutOff1/CutOff2 Wah will be applied at the LFO1 or LFO2 frequency .
LFO 1/LFO 2 ®Level
Tremolo will be applied at the LFO1 or LFO2 frequency.
LFO 1/LFO 2 ®Panpot
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.
MIDI1 (P.Bend) ®Panpot
PITCH wheel operations or pitch bend change will move the sound be-
tween left and right.
On modular analog synthesizers, the input
or output of each module (oscillator, filter,
amp, EG, LFO, and other controllers) could
be connected ("patched") by a patch cord
to any other module as desired, allowing
you a great deal of freedom in creating the
sound. The Korg MS Series (MS-20, MS-50,
MS-10, etc.) went on sale in 1978 and fea-
tured this type of patching. The R3 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 (destina-
