VCO BANK
The
Voltage
Controlled Oscillator
(VCO)
is
the primary source of sound for
a
synthesiser, and determines the pitch
and bas*c
tonal quality, or timbre, of all
sounds produced. The Korg Mono/Poty is
comprised of four separate VCOs. «ach
with independent Octave.

the
following
advantages:
• In
the
Monophomt lUntson) mode,
allows mixing of different waveforms
and/or
octaves
in the same note, for
richer, fuller
sounds,
• In ihe Poly, Unison/Share and Chord
Memory modes, the
use*
may struc-
ture highly complex polyphonic
chords with different octave and/or
timbre
selection
for
each note. or. he
may
create four
note
homogeneous
sounds (all
notes with
the same
tim*
tart).
• VCOs can
be
arpeggiated or even
played sequentially (<**, a different
VCO sound for each new Key depres-
sion),
by
using the MP-4's Arpepolator.
This can produce interesting mythrnic/
random-type effects especially when
different
octave, waveform and/or
level
setting*
per
VCO are used.
1. Tuning Controls
Overall tuning among
the
four
VCOs Is
determined
by the
different
Tuning con
trols,
as
follows
Trampott:
Transposes the pitches
of
all four VCOs up
or
down one octave
(The rear panel CV OUT jack is also
affected
by this
switch).
Miner Tune
(in
VCO J section):
Varies the pitch of all four
VCOs
simul*
taneously over
a
range of ±
50
cents, for
tuning the Mono/Poly
to
Other instru-
ItWl is, etc
Individual Tune IVCOs 2, 3. A)
Varies the tuning of the
individual
VCOs
relative
to VCO 1 by i SO cents. Theea
controls are normally
used to initially
tune all
four oscillators
to
unity
pitch;
once
tuned,
these controls
should not
require furl her

in the

Oscillators are conve-
niently returned
to
perfect intonation
by
turning
the Detune
control
back to
"0"
for Polyphonic playing, without
con

having
to adjust separate VCO
Tune controls.
