MIDI
IN and
OUT
Connectors
In
addition
to
allowing
input
from
an external
MIDI
keyboard or other
MIDI
instrument via the
MIDI
IN
con-
nector
(Reference,
page
49), the
QY10
outputs
all
sequence
playback
in real
time via the
MIDI
OUT
connector
so that
external
tone generators
and rhythm machines
can be driven
if
required.
The
QY10
also
allows
sequence
data
to
be
"bulk
dumped"
to
other
MIDI
sequencers
or
keyboards
with built-in
sequencer
functions, as well as
to
a
second
<W0
(Reference,
page
93).
You
can, for
example, do
the
tuj/c
programming
for a
composition on
the portable
QY10,
then
dump
the data to
your computer before
finishing
it
off.
You
can
also
dump
the data
to a
MIDI
data recorder
for
long-term high-capacity
storage.
