Attenuate Output Level; Limit Lowest Key - Yamaha TX 816 Owner's Manual

2.
Attenuate Output
Level (press
SW3
twice)
FM
generated voices have
a
vase range
of timbres,
and
their overall levels
may
vary.
If,
for
example, you wish
to
change
voices during
a
composition, you
may
need
to
balance
up
the
different
voice
levels.
This
is
done
by
utilizing
the Attenuate
Output
Level
sub-mode.
This allows
you
to adjust the output
level
of individual
voices
in
approximately
5
dB
steps,
indicated
by numbers from
to
7.
Pressing
SW1
or
SW2
raises or
lowers the
level
respectively
by
one
5dB
step
at a
time.
Holding
down
either of
these keys
moves you
rapidly
through
the attenuation
settings.
The
data entry lever of the
DX7 may
also
be used
to
alter
the attenuation
setting.
The
LED
Display
example above shows an Attenuate Output
Level setting of
7.
This data
change
will
not be permanent
until
it
is
stored
into
the
TFI's
internal
memory.
It
is
possible to store
only function
data,
in
as
many
"destinations" as
you
like.
This
means
that
you can
rapidly set several different
voices
to
the
same
output
level
(see
STORE
MODE
chapter. Store
Only Function
section).

As
described
in
the
SETTING
UP
chapter,
it
is
possible to allocate a
voice
to
any
part of
your keyboard, by
selecting
high
and low
note
limits. All
FM
voices
can
be generated over
a
range
of
up
to
127 semitones
(over ten octabes),
from
C-2
(note
C
in
octave -2) to
G8
(note
G
in
octave
8),
depending on
their
frequency
ratio
setting.
These correspond
to
MIDI
note
numbers
thru 127.
The keyboard
of a
DX7
spans
the 5 octave range "01
"
to
"06", so
it
is
easy
to select
note
limits
applying
to this
instrument.
This
sub-mode
lets
you
select hte
lowest note of
the range
in
which you wish
to
limit
the voice.
This
is
simply
done
by using the
SW1
and
SW2
keys to select the required note,
over the
available
range
C-2 (C minus
2) to
G8.
The
keys
change
the note
one
semitone
at a
time (up
or
down,
respectively)
when
pressed,
and
when
held
down
run
rapidly
up
or
down
the
scale.
The
Limit
Highest
Key and
Limit
Lowest Key
functions
are
the only parameters
that
can
NOT
be edited
from
the
DX7
keyboard.
Negative octave
numbers
are
indicated
by
a small
dot
in
the lower
right of
the
LED
Display.
Sharp notes
are indicated
by
a
small dot
in
the
upper
left
of the
LED
Display.
(There
is
no
indicaiton for
flat
note- -only
the
enharmonic shapr note
is
given,
i.e.
E
flat
= D
sharp,
B
flat
+
A
sharp,
etc.)
The
LED
Display
example above
shows
that
the selected
low
key
limit
is
C
sharp
in
octave -2.
