Using
MIDI
1
Simultaneously
Controlling
Two
or
More
MIDI
Devices
As
illustrated
below, connect a cable
between
the MIDI
OUT
on
the JV-30,
which becomes
the
master,
and
the MIDI
IN
on
Slave
1.
Then, connect the MIDI
THRU on
Slave
1
with the MIDI
IN
on
Slave
2.
When
connected
in this
manner,
the performance information
from
the master
is
sent to
Slave
1
and
Slave
2,
so
whatever
is
played
on the master keyboard
will also
be sounded by
Slaves
1
and
2.
This
method
is
referred to as
a
"Series
Network".

However,
this
method
may
be
unsatisfactory,
because the further
from the master
that
the
device
is
located,
the
more
delay there
is
that
could occur. Signal deterioration
is
also a
consideration.
If
connection of
4
or
more
devices
is
required,
we
recommend
that
you
use a
MIDI
Patch
Bay
(eg.,
A-880, available separately),
and
make
the connections as
illustrated
below.
This
method
is
referred
to as a "Star Network".
