In the TX81
6 the
COMMON
MIDI IN and
OUT
terminal
are used to
send or
receive
Cotninon
MIDI
signals
to
and from
atl
the
TF1
modules
simultaneously.
The
TF1
modules
must be
switched to
"COMMON"
for
this
to
occur.
This is
done
by
pressing
SW1
so that
the
COMM'ON
LED lights.
==
A term used
in the
MIDI system, do
describe the
connecting up
of two or
more
Dsisy
ChBining
MIDI devices so
that the
same
MIDI
signal
controls
them
all. For example, a
single
DX7
could control any
numberof other
DXs
using the
following
daisy-chain
pro-
cedure:
Connect MIDI
OUT of
DX7 no.1 to
MIDI IN of
DX no.2.
Connect
MIDI
THRU
of
DX7 no.2 to the
MIDI IN of
DX7 no. 3. This
sends
DX7
no.Vs
MIDI signals
to
DX7 no.
3.
Further
daisy-chaining is
done
by
connecting
MIDI THRU
of
DX7
no.3 to
MIDI IN
of
DX7 no.4,
and
so
on.
Daisy
chaining of TF1
modules is
detailed
in the
SYSTEM
EXAMPLES
chapter (A
Variation
on
System'

Another word
for computer
information,
of any
kind.
This can apply to

In
essence,
anything
expressed
in
numbers.
Digital
instruments
function
by
reducing
DigitBl
all the
elements of
sound
to
numbers,
which can be
handled,
and even
created,
by
computer technology.
Digital music
functions in the
same
way,
reducing
atl
elements of
music
(timing,
volume,
pitch, etc.)
to
numbers.
Digital
recording
also
reduces
musical signals to
numbers, so that
what
is stored
on tape
is
pure
information
rather
than
audio
signals, and
hence
Is
completely
distortion-
free.

Transfer
a

data from
one
MIDI device
to
another.
The Dump
All
Dump
Voices and
Function Sub-mode
on the
TF1 allows you to
dump its
entire
voice
data
to
another
source, e.g. to a
floppy
disk
where It can be
permanently
stored.
==
A temporaty
store
for data.
When you
select
any
voice on
the
TF1
for editing or
Edit
Buff&t
play
back, its data
Is loaded
from the
internal memory
(where It is
permanently
stored) to
the Edit
Buffer. This data
can
now be
edited in a
variety of ways,
or used
to
drive the
FM
Tone
Generator in the
TF1
and produce
sound.

Describes notes
that
have
the same
pitch but
different
names,
e.g.C
sharp and
D
EnhBrmoniC
fiat.
Prior
to
the
relatively
modern
"well-tempered"
system
of
tuning, two
such
notes
would
actually
have
different pitchs.
In other words,
the
amount you
would
raise
the pitch
of
C to get C
sharp
would not be
the same as
the amount you
would
lower
the pitch
of D
to
get
D
flat,
hence the
two
notes
would
have different
pitches.

A
compact
means
of
storing data.
Originally,
computer data
was
stored
on large
Floppy
Disk
reel to
reel tapes (it
still
is,
with large
computers),
with the
introduction
of
personal
computers.
It was
possibles to
store
data
onto
regular
cassette tapes.
In both
these
cases,
finding
specified
data on tape
meant
winding
through
the
whole tape
until
you
reached
the desired
point. This is a
rather
slow
process.
Floppy
disks,
which
are made
from the
same
magnetic
material as
recording tape,
allow you to
find
data
much more
quickly, by
scanning across
the
disk in the same
way that a
tone
arm moves
across
a
phonograph
record.
Floppy disks are
now the accepted
way
of storing
data
for
personal computers,
and come
In
various sizes.
