Yamaha TX7 - System and Memory Configuration; TX7 and DX Function Memories

SYSTEM
I
MEMORY
CONFIGURATION
The
TX7 incorporates the same FM
tone generation
system found in Yamaha DX
series Digital
Programmable
Algorithm synthesizers
and the Yamaha TX21
6
and
TX81 6 tone
generator
systems.
This
is a 6-operator,
32-algorithm
FM
system which is
programmable
via the DX
series synthesizers
having the corresponding tone
generators --The
DX7
and DX1
,
for
example. Since the
TX7 does not permit
direct voice
programming,
we
refer
you to the doc-
umentation
provided
with the
respective
DX
synthesizers for
details
on the FM tone
generator system
and pro-
gramming
procedures. The
Voices programmed
in
a
DX
synthesizer
can be loaded into the
TX7 via the MIDI interface,
however,
and voices residing in
the TX7 voice memory
can
be sent to
a
DX
synthesizer. The
TX7 does permit
direct
programming
of
its function
memories
(described
below) via the front
panel.
The
TX7
also has a
data
cassette
interface which
can
be used to store and
load the entire
contents of the TX7 memory.
The TX7 has
32
voice
memories,
each
of
which
contains the
data
for
one
complete 6-operator FM
voice.
Each of these voice
memories
also has
a
function
memory which
contains the
data for the function
and
control parameters
of that voice.
The
programmable
function
parameters are given in the
following chart:

Thus, each TX7 voice can
be
independently programmed
with its own
real-time
performance
effects
parameters
--
pitch wheel,
modulation
wheel,
foot controller,
after touch
response, breath
controller, etc. When
a specific
voice is selected, its
function parameters are automatically
selected
as well. These function
parameters
are directly
programmable via the TX7
panel controls, or they
can be sent to the TX7
from
a
DX
synthesizer, via the MIDI
interface.
The TX7 also contains a
second
set
of 32 function
memories which is independent
from that for
the
TX7
voice
memories. This
second function memory set
is intended
to be used with the
voice memories
in
the DX7
synthesizer.
