HOW
TO
PRODUCE SOUND
The panel layout
of the CS-15
is
as follows:
Two VCO
-
VCF
-»
VCA
systems
are situated
above each
other
in
the center
and
the blocks controlling these
in
its vicinity.
The
thin lines
combining
each block
indicate the
signal
flow. First
we
will
merely
indicate the
basic setting for producing sounds
experimentally
to
check
the synthesizer or
amplifier.
This
is
an example
in
which
triangle
waves
are generated
in
one
system (upper
side)
and
square waves
in
the other system.
We
will describe
this
setting
first
and
then
go on
to explain each block
and
the functions
of each knob.
It
is
advisable to actually perform
these settings
and
confirm
the results
by
ear
in
order
to fully understand
all
functions.
BASIC SETTING
1.
Connect
the
synthesizer properly
by
referring
to
CONNECTIONS
on
previous
page.
2.
Set
the switches and knobs
as illustrated
below
with
arrow marks.
•
Do
not
use the other knobs
yet.
3.
This completes
the basic
setting to
produce
sounds.
• The
knobs and
switches have
serial
numbers
from(T)to
@,
and
are explained under
that
number.
®
POWER
SWITCH
When
pushed down,
the synthesizer
is
switched on
and
the indicator illuminates.
©
VOLUME
This
is
used
to control the
overall
volume
of
the
OUTPUT
block.
• The volume
control
on
the
amplifier
and
that
of the
CS-15 determine
the
final
volume.
®
KEYBOARD
The CS-15
covers
3
octaves
with
37
keys.
When
two
or
more
keys
are depressed
at
the
same
time,
priority
will
be given to the
key
of
the higher
pitch.
The
CS-15
is
a
monophonic
synthesizer with
higher-pitch
priority.
When
keys
are depressed
in
the basic
setting,
sounds
are
produced.
If the
INITIAL
LEVEL
knobs
©
and
©
in the
VCA
block
are
turned towards
10,
sound
can be produced
even without keys being
de-
pressed. This
is
convenient
for
sound
experi-
menting
purposes. (For
