Buffer
NOTE:
Any terms referring
to
parameters
or functions
of the DX7 are
explained
in
its Owner's
Manual
(e.g. Portamento,
glissando, etc.) and are not included
in this
glossary.
The
definitions
explain
the
use of each term when
applied
to the tX81

or other
Yamaha
digital music
instrument,
although some general
definitions
are included.
"^^^^
Reduce
the
level
of
a signal. In
the
TF1,
the
Attenuate Output Level
Sub-mode
AttBilUSte allows
you to
reduce
the output level
of an incivicual
voice in 5
dB steps
from 7
(its normal
setting) thru
0.
The voice
and function
memory in the TF1 modules are
backup up by a
Lithium
BsckUp
BBttery battery so that
the
data
is not lost
when the TF1 power
is turned off.
NOTE:
The
battery needs replacing
about every 5
years.
Check
its
level
periodically
by
using the
Read Out Current
Voltage of Battery
sub-mode. See the UTILITY
chapter.
^^^^^^^^^=
jhe smallest unit of
computer information
that can be sent. For

the
binary
Bit
number 1100 is
a "4-btt" number. It's first
bit is
1,
corresponding
to 'Pulse'. It's
second bit is
0,
corresponding
to "No pulse'. See the HOW THE MIDI
SYSTEM
WORKS
chapter.
'
Refers to numbers
based on powers
of
2,
as opposed to the normal Dicimal

Binsry based on

.
A
group of bits.
In
the MIDI
system, most simple
commands are sent
as
an
8-
bit
Byte byte. For example,
the Program
Change command (a two-byte command) contains
the Status
byte
1 lOOnnnn.The
first part fo this byte, 1
1
00,means "here
comes the
MIDI
channel
number for a Program Change"; nnnn
indicates the MIDI
channel
number, which can range from
0000
for
channel
1
to 1111 for channel 16. See
the HOW THE MIDI
SYSTEM
WORKS chapter for more explanation,
and the
MIDI
FORMAT
section
for
examples.
