An abbreviation
for
Light Emitting Diode.
Tlie diode
glows when a
voltage is
applied
LED
to it
On the
TF1, 5
small
LED's indicate
function
such as
INDIVIDUAL and
COM MON,
while an LED
Display can
show two
alphabetical
or
numerical characters
created
by
seven
smalt diodes each, to
indicate modes, data, etc.
In the
TF1, the process
of
transferring data
from
the
internal
memory
to
the
Edit
Load
Buffer, where it can be
edited or used
to
control the
FM
Tone
Generator and
produce
sound. In
general computer use,
load
means
transferring data
from
permanent
storage (e.g.
floppy disk) to
temporaty
storage
such
as
the
computers
fuffer.
NOTE: ,
The data
is not
actually
transferred, it is
copied into
the
new destination, and
remains in fact in
the
original source.

An abbreviation
for
Musical
Instrument
Digital Interface.
Essentially, a means
for
MIDI
digital
devices to
control each
other.
This system has
revolutionized
electrinic
music
41^
and
made
possible
the
simplicity and
sophistication of
Yamaha's
digital music
instruments. See the
HOW THE MIDI
SYSTEM
WORKS
chapter.
—
Computer
controlled
instruments
contain numerous
microcircuits
that can be used
Mode
for a variety
of
purposes.
Switching
to a mode
instructs
the
instrument
to
perform
a
specified set of
functions,
ususlly related
to each
other.
For example, the
TF1
's
Edit mode
allows
you
to select
and
alter FM voices
in
a
variety of
different
ways,
while the Store
mode
lets you
store voice
data or
function data
in any
selected
program destination.
The TX816 has
four
different modes.

A

Module
part of a
larger system.
The
TF1 module
incorporated into the
TX^I
6
Tone
Generator
System
produces a
single
FM voice
(although
it can
store the data
for
32
voices)
and
can be
played
individually
or
sumultaneously with
the
other
mokules
in
the
system. It
can be
easily
removed
for repairs or
battery replacement,
without
affecting
the
functioning
of the
other
modules.
==^^===^^
An
individual
characteristic of an fM
voice,
which can be edited
and stored.
Each
Parameter
FM voice
is
created by
setting
the value
of
145 editing
parameters
(voice
data-
-listed in
section
4-1
of the
MIDI FORMAT
chapter)
and 25
Function
pa-
rameters
(function data-
-listed in the
Clear and
Initialize
All
Functions
section
of
the
UTILITY
MODE chapter).
When
applied to
mixing
consoles,
"parametric
EQ"
describes
equalizers
(Filters)
whose
frequency
and
bandwidth can be
changed
as
well
as
their level
setting.
A
combinaiton
of voice data
and
function data.
32
such
combinations
are
stored
Program
in the internal
memory of each
TF1. When you
select
a program
for editing or
playback,
both sets
of data
are loadet
into the
Edit
buffer.
===^^^===
One of the
32 sections of the
internal
memory of
the TF1
,
which
can store
both
Program
destination
voice data and
function
data to
make up a
program.
This is done
in the Select
Destination
sub-mode (see the
UTILITY MODE
chapter).
