Outline
of
the
TR-727
The Rhythm Composer TR-727
is
a fully
program-
mable
rhythm machine which
allows
you
to pro-
gram 4
Rhythm
Tracks
or tunes (altogether
998
bars)
from
up
to
64
kinds of user-dreated
Rhythm
Patterns.
Each
of
the 15
digital
drum
voices
is
extremely
realistic
and
has
a
separate
output
jack
for individ-
ual
mixing,
echo
or
equalizer.
An
optional
memory
cartridge plugs directly into
the
Composer
for
instantaneous loading
and
saving,
expanding the
memory
capacity
by
three
times.
A
Display
window
helps
your
operation to
great
extent.
MIDI
Bus
on
the
rear
panel
interfaces
with
other
MIDI
devices to
allow
control of
several
instruments.
Flam
(Grace-note)
and
Shuffle can
be
added
for
greater variety
and
realism.
Now
we'll
find
our
way
around
the important
controls
before
creating
and
storing
('writing')
our
own
rhythm
tracks.
With any
computer
keyboard,
the
same
key
may
do
several different
jobs
depend-
ing
on
how
it
is
used.
The
Composer, which
is
a
type
of
computer, does
this
also.
When
switched
on,
the
Composer
automatically
selects (or 'defaults' to)
Track
I.
"Default"
means
the value automatically
selected
by
the
Composer
overriden
by your
command.
A
Track
is
a
complete tune
in
rhythm,
made
up
of
Patterns
strung together (Patterns
are
covered
later),
and
there
is
a
demonstration tune
written
on
Track
I.
The SHIFT
Key
is
used
a
lot.
It
enables
many
but-
tons
and keys
to
perform
two
functions
instead of
just
one.
The
distinction
is
clearly
marked
on
the
Composer:
all
functions enclosed with
lines
and
highlighted
are selected
while the
SHIFT
Key
is
held
down.
All
other functions
do
not need the
SHIFT
Key.
The
only exception to
this rule
is
the
ENTER
Key.
The
Main
Keys
numbered
1
to
16
are
used
for
several tasks:
(i)
They
produce the
voices
manually
when
tapped.
(ii)
They
divide
a
bar of
music
into
16
parts,
and
enable
voices to
be
written
into
any
of
these
parts.
(iii)
They
assign
the
instrument
voices
in
turn
when
you
are writing.
(iv)
They
take
care of
all
the
"housekeeping"
in-
volved
in
editing
Rhythm
Patterns
and
Track,
such
as delete, insert
and
copy.
(v)
They
set
the
Accent on
the
major
voices.
Above
the
Main Keys
is
the
scale
of
time
values with
a
red
LED
beside
each
to indicate
which
is
in
opera-
tion.
These
indicate
whether you
are
operating
in
2/4,
3/4, 4/4,
6/8 or
multiples
of these
times.
Default value
is
4/4,
other times
are
set
with
the
SCALE
button.
Special
times such
as
5/4,
7/4
or
any
other can be
set
with the
LAST STEP
button.
Mixed
times
which
change
each
bar can
also
be
set
up.
We
use the
CLEAR
button
to erase
rhythm
patterns
we
want
to write
over,
the
FLAM
button
for
adding
Flam
or
'grace notes'
ahead
of
the
main
beat,
and
INSTRUMENT
SELECT
for selecting
each
voice
in
turn
when
writing
Patterns.
Finally,
don't
worry
if
you
can't get
an immediate
response
from
these
controls;
sometimes
they
operate only
under
special
circumstances to
protect
your
data.
A
full
explanation
of
all
controls follows
in
this
Manual.
