Yamaha TX7 Owner's Manual page 8

The
DX7
itself
also
has
32
voice
memories, but
only
a
single function
memory.
Thus,
if
a
new
voice
is
selected
which requires a
different set of
function parameters, these
must be
re-programmed
via
the
DX7
panel controls.
The
TX7
supplies the
DX7
with
a
complete
set of
32
function
memories corresponding to
each
voice.
In
the case
of
the
DX9, which only has
20 voice
memories, the
TX7's
first
20
(1
through 20)
DX
function
memories
apply,
and
only those functions
which
the
DX9
incorporates
can be used.
In
the basic
system connection
configuration
given
in
the previous section,
each time
a
new
voice
is
selected
on
the
DX
synthesizer,
the
corresponding function
memory
in
the
TX7
is
called,
and the parameters
it
contains are
automatically sent to
the synthesizer via the
MIDI
interface.
The
TX7
also
has voice
and
function edit buffer
memories,
which contain the voice
and function data
in
use.
