HOW
TO
USE
THE
TX7
1.
What is
the
TX7?
The
TX7 is
a
tone
generator
module
that
can
be
controlled
by
MIDI
signals
from
the
DX
series,
QX1
,
CX5
etc.
It
is
the
equivalent
of
the
DX7
tone
generating
section.
When
connected to a
DX7
or
DX9,
it
can
act as a
function
memory
for the
DX7
or
DX9,
and
thus
allow
you
to
create
sounds
just
like
a
DX1
.
[Features]
•
FM tone
generation
system.
•
16
note
polyphonic.
•
Internal
memory:
32
voice
data,
32
function
data,
stored
in
pairs.
Each
voice
memory
has its
own
function
memory.
•
Individual
volume
and
high
and
low
note
limits
can be
set
for
each
voice
memory.
Also,
independently
of
the
voice
memory,
two
volumes
may be
preset,
and
recalled
instantly by a
front
panel
switch.
This
can
be
used
for
muting.
•
Besides
the
TX7's
own 32
voice
memories
and 32
func-
tion
memories,
it
will store
32
function
memories
for
the
DX7.
This can
be
used
as
an
extended
function
memory
for
the DX7.

The
voice and
function
data
of
the
selected
memory
number
is
loaded
into
the
voice
and
function
buffers.
Then, the
voice
and
function
data is
loaded into
the
FM
tone
generator,
and it
is
ready
to
produce
sound.
All
editing
of
voice
and
function
data
is
done
on
the
data
in
the
buffers.
When
the
store
command
is
executed,
the data
in
the
buffers is
stored
into
the
respective
memories.
The data
in
the
function
edit
buffer
will
be
stored
into
the
memory that
you
designate.
