WAVESHAPE
(A)
Provides
continuous
waveshape
control
of
OSCILLATOR
A;
calibrated
in
arbitrary
units.
The
position
marked
"0"
provides
the
sawtooth
wave
form;
as
the
control
is
moved
clockwise,
this
sawtooth
is
mixed
with
a
narrow
rectangular
waveform.
As
the
WAVESHAPE
control
is
moved
toward
the
position
marked
"5/'
the
rectangular
waveform
widens
and
the
sawtooth
truncates.
Between
"5"
and
"6"
a
square
waveform
is
produced;
as
the
control
is
moved
on
toward
"10,"
the
square
waveform
narrows
to
a
narrow
rectangular
wave.
The
narrowness
of
this
rectangular
waveform
is
limited,
making
it
impossible
to
"lose"
the
sound
at
any
WAVESHAPE
setting.
Sawtooth,
square,
variable
rectangular,
and
a
mixture
of
sawtooth
and
variable
rectangular
waveforms
are
available.
This
continuously
variable
WAVESHAPE
control
allows
a
change
of
the
harmonic
spectrum
of
the
output
of
the
instrument
that
is
independent
of
the
FILTER
control
settings.

MIX
Provides
a
continuous
mix
of
the
audio
oscillators
A&B.
Full
counterclockwise
position
"A"
provides
the
output
of
OSCILLATOR
A
only.
Full
clockwise
position
"B"
provides
the
output
of
OSCILLATOR
B
only.
Intermediate

repre
sent
mixes
of
the
two
oscillators.
Calibration
is
arbitrary,
in
units
from
"0"
to
"10."

OCTAVE
Selects
to
tune
both
oscillators
in
octave
increments
from
32'
to
2'
stops,
with
middle
C
on
the
keyboard
as
footage
reference.
The
rightmost
position
activates
the
adjacent
WIDE
FREQ
control
in
order
to
provide
continuous
tuning
of
both
oscillators
over
an
eight
octave
span.
Fine
tuning
in
all
positions
of
OCTAVE
is
accomplished
using
the
FINE
TUNE
control
on
the
rear
panel.
The
CUTOFF
control
of
the
FILTER
is
internally
arranged
to
track
the
OCTAVE
control
to
maintain
consistent
tone
color
in
all
pitch
registers.
When
the
FILTER
MODE
switch
is
in
the
FULL
position,
a
pitch
change
of
one
octave
is
ac
companied
by
a
concomitant
change
of
one
octave
in
the
cutoff
frequency
of
the
filter.
In
the
NORM
(normal)
position,
the
cutoff
frequency
is
changed
by
a
half-octave
per
each
pitch
change
of
a
full
octave.
The
OCTAVE
selector
is
a
performance
control
which
expands
the playable
span
of
the
keyboard
to
a
full
eight
octaves.
5
WIDEFREQ
Provides
continuous-sweep
tuning
over
approximately
eight
octaves,
operable
only
when
the
OCTAVE
selector
is
placed
to
the
rightmost
position.
The
WIDE
FREQ
control
is
calibrated
in
octaves;
the
center
point
marked
"0"
places
the
Multimoog
in
approximately
the
8'
range.
Settings
on
the
WIDE
FREQ
control
do
not
interfere
with
any
of
the footage
(32'-2')
settings
on
the
OCTAVE
selector;
the
WIDE
FREQ
control
is
operable
only
when
the
OCTAVE
selector
is
set
to
its
rightmost
position.
The
WIDE
FREQ
control
tunes
both
oscillators
proportionately-
tuned
intervals
remain
the
same
over
the
entire
tuning
span.
The
WIDE
FREQ
control
is
fine-tuned
using
the
FINE
TUNE
control
on
the
rear
panel.
The
WIDE
FREQ
control
may
be
"preset"
to
any
pitch
level
to
allow
instantaneous
transposition
(when
OCTAVE
control
is
set
to
activate
WIDE
FREQ).
