Setting Up The Sync Square Oscillator:
The
Sync
Square
oscillator
is
actually
comprised
of
two
oscillators,
a
master
and
a
slave,
set
up
to
emulate
the
way
sync
square
oscillators
worked
on
classic
analog
synthesizers.
To
create
a
program
using
Sync
Square,
select
Default
Program,
#999.
Select
ʺ
none
ʺ
on
the
keymap
page.
Select
ʺ
user
ʺ
on
the
Ampenv
page
for
an
amp
envelope.
On
the
ALG
page,
select
Algorithm
5
at
the
top
of
the
page.
Use
the
cursor
buttons
to
select
the
function
block
and
use
the
alpha
wheel
to
select
the
ʺ
SYNC
SQUARE
(master)
>>
ʺ
function.
Next,
press
the
<<
soft
button
to
change
soft
button
pages
until
you
see
ʺ
DupLyr
ʺ
.
Press
DupLyr
to
duplicate
the
layer,
creating
layer
2.
In
layer
2,
on
the
ALG
page,
change
the
function
block
to
ʺ
>>
SYNC
SQUARE
(slave)
ʺ
,
and
set
the
Alt
Input
parameter
to
ʺ
Layer
1
ʺ
.
The
final
step
is
to
go
to
Layer
1
ʹ
s
DSPCTL
page
and
turn
the
Level
parameter
all
the
way
down,
to
‐
96dB
(this
ensures
that
you
will
only
hear
the
output
of
the
slave
oscillator
on
layer
2,
which
is
the
intended
function
of
Sync
Square.)
Now
the
Sync
Square
oscillator
should
be
working.
The
ʺ
Syncoff
ʺ
parameter,
Sync
Offset,
is
the
main
parameter
for
shaping
the
tone
of
this
sound.
Syncoff
sets
the
sync
offset
between
the
master
and
slave
square
waves
in
each
corresponding
oscillator,
which
changes
the
shape
of
the
waveform
output
by
the
slave
oscillator.
The
Sync
Square
oscillator
is
most
expressive
when
the
Syncoff
parameter
modulated
during
performance.
Use
the
DSPMOD
page
to
assign
an
envelope
or
continuous
controller
like
the
Mod
Wheel
for
this
parameter
to
hear
the
effect
(see
The
DSP
Modulation
(DSPMOD)

on page 6
‐
29,
as
well
as
The
DSP

(DSPCTL)

and

to

parameters,

(ENV2)
and
Envelope
3
(ENV3)
Pages
on page 6
‐

for
details
on
using
envelopes
as
modulation
sources.)
See
Advanced
Use
Of
KVA
Oscillators
below
for
some
similar
examples
of
how
to
set
and
control
modulation
for
oscillator
specific
functions
and
other
parameters.
To
add
a
DSP
function
to
the
Sync
Square
oscillator,
you
ʹ
ll
need
to
use
cascade
mode.
For
example,
to
add
a
filter,
duplicate
one
of
the
layers
to
create
layer
3.
On
layer
3,
select
the
ALG
page
and
choose
one
of
the
cascade
mode
algorithms,
algorithms
101
‐
131.
For
this
example,
lets
use
alg
105
with
the
filter
ʺ
4Pole
Mogue
LP
ʺ
selected
for
the
function
block.
For
the
Alt
Input
parameter,
select
Layer
2.
This
routes
a
pre
‐
Level
parameter
copy
of
Layer
2’s
output
into
Layer
3.
Go
to
layer
2
ʹ
s
DSPCTL
page
and
turn
its
level
down
to
‐
96dB
(otherwise
the
un
‐
filtered
sound
from
layer
2
will
be
audible
as
well
as
the
filtered
sound
in
layer
3.)
Now
you
can
hear
the
Sync
Square
from
layers
1
and
2
running
through
the
filter
in
layer
3.
See
Advanced
Use
Of
KVA
Oscillators
below
for
examples
of
how
to
set
and
control
modulation
of
filter
parameters.
Advanced Use Of KVA Oscillators
Read
the
KVA
sections
above
before
moving
on
to
this
section.
If
you
have
tried
the
program
described
above
in
Basic
Use
of
KVA
Oscillators
,
you
may
have
noticed
that
there
is
no
variation
in
the
notes
played
aside
from
pitch.
Layers
and
programs
created
with
KVA
oscillators
can
become
much
more
expressive
by
introducing
variation
with
DSP
modulation.
For
a
KVA
oscillator
layer,
you
can
use
DSP
modulation
just
as
you
would
for
keymap
layers
(see
Common
DSP
Control
Parameters
in
Algorithm
Basics
on page 6
‐
13,
The
DSP
Control
(DSPCTL)
Page
on page 6
‐
28,
and
The
DSP
Modulation
(DSPMOD)
Page
on page 6
‐
29.)
Several
KVA
oscillators
also
have
their
own
modulation
parameters
that
must
be
accessed
to
control
the
oscillator’s
intended
function.
Aside
from
these
methods,
KVA
layers
can
also
be
altered
by
using
keymaps
with
natural
amplitude
envelopes.
See
below
for
details
on
each
method.
Examples of Simple DSP Control and Modulation:
Select
the
program
1019
VA1NakedPWMPoly,
and
press
the
Edit
button.
Press
the
ALG
soft
button
to
view
the
algorithm
and
function
blocks
in
use.
The
3
block
PWM
oscillator
that
you
see
is
generating
the
sound
in
this
program.
Select
the
empty
function
block
to
the
right
of
the
PWM
block,
and
use
the
alpha
wheel
to
scroll
to
the
LOPASS
function.
You
should
immediately
hear
a
difference
in
the
sound
of
the
program,
because
the
LOPASS
function
is
set
by
default
