By connecting external
signals
to the
EXTERNAL
terminal
provided
on
the
rear
panel,
it is
possible to use
these external signals as
sound
sources.
It
is
also
possible
to
make
the trigger signals
with
which
the
start
of the
envelope generator
(EG)
is
controlled,
by detecting the
waveforms
of these
signals.
Accordingly, synthesized
sounds can be
gained (by the unit functioning,
for ex-
ample,
as a
guitar synthesizer),
when
an electric guitar,
or
an
electric
piano
is
connected.
©EXTERNAL
This
is
a
terminal
used
for
feeding
in
external
signals
such
as
those of an
electric guitar,
or
elec-
tronic piano.

& LEVEL
(VCF1)
When
external signals are
used
as
the
sound
source,
the
INPUT
switch
is
to
be
set
to the
EXT
side
and
the
volume should be adjusted
by means
of the

When
the
trigger
is
to
be applied
by
external
signals,
the

switch,
KBD/EXT
is
to
be
set
to

the
condition of

cation should
be adjusted
by means
of

WHEN
USING
TWO
SYNTHESIZERS
By
using
the
KEY
VOLT, TRIGGER
and
SEQUEN-
CER
terminals
to
transmit the data of
this
CS-30L
to
another
CS-30L
(or to
other
synthesizers
having
similar
terminals), this
synthesizer can be used
as
a multiple-
system
synthesizer.

KEY VOLT
This
is
the voltage
by which
the
intervals
of
the
VCO
are
determined.
(2)
TRIGGER
This
is
the signal to
indicate the
KEY-ON
and
KEY-OFF
timings of the
keyboard.
