CONNECTING
TWO
SYNTHESIZERS
The CS-15
has terminals for input
and
output of
CONTROL VOLT
signals to
control
the
voltage
corresponding
to
the
interval
of
the
keyboard,
TRIGGER
to
EG.
It
can
also
feed
them
to
a
dif-
ferent synthesizer having the
same
input /output
terminals or receive
them from
another
synthesizer.
Thus,
one keyboard
can control
many
VCO
-
VCF
-+
VCA.
• The
terminals of the following models
have equivalent function
as
the
CONTROL VOLT
of the
CS-15.
CS-10, CS-30 and CS-30L:
KEY VOLT
CS-30:
CONTROL VOLT
of the
SEQUENCER OUT
port
•
CONTROL VOLT
and
TRIGGER
can
be fed
in
and out independently.
•
For
further
details
on main and
sub con-
trols
when
two
or
more
synthesizers are
connected,
see

BLOCK DIAGRAM

CONTROL VOLT
An
input/output terminal
for the
CONTROL
VOLT
or
KEY VOLT
terminals of other
synthesizers.
IN
VC0
1/VC0
2
Terminals
to feed the
CONTROL VOLT
or
KEY
VOLT
of
other synthesizers
into
VCO
1
or
VCO
2.
OUT
A
terminal
to
feed
it
to
other
synthesizers.
O
TRIGGER
Input/output
terminals
between
TRIGGER
termi-
nals
of
other
synthesizers.
IN
EG 1/EG2
Terminals
to feed
in
TRIGGER
signals controlling
EG
1
or
EG
2 from
other
synthesizers.
OUT
A
terminal to feed
TRIGGER
signals to
other
synthesizers.
• Wrong
connection of these controls can cause
damage,
so careful attention should be paid
when
making
connections.
The
following
is
an
example
in
which
the
CON-
TROL VOLT
and
the
TRIGGER
signals of the
synthesizer
1
(CS-15)
are
transferred to the
VCO
2 of the synthesizer 2 (CS-15).
Thus
the synthe-
sizer
1
keyboard
can
control three systems con-
sisting
of
two
systems of
the synthesizer
1
and one
system
(VCO
2)
of
the synthesizer 2
at
the
same
time.
The
VCO
1
side
of the synthesizer can be
normally operated by
the
keyboard
of
the
synthe-
sizer
2.
As
a
result,
a
multi-keyboard
use
is
possible,
in
that the synthesizer
1
controls three
systems
and
the synthesizer 2
one
system.
