inio non-volatile
memory
(battery
back-up),
with
up to
seven different

sounds
plus

Then you
can adjust the

for

Programming
several
rhythms
can be
accom-
plished
and stored
in a
particular
order
in the
memory,
forming
the entre
rhythm
track
of
a
song.
This music can then
quite easily
be
amended,
since
the
TR-606
includes
a simple.
yet
effective,
ediiting
facility.
In this manual, we
shall refer
to each
bar
of
music as a
"Rhythm
Pattern".
So. the
TR-606 lias
mainly 2
basic
functions.
One
of
them
is "Writing/Playing
a
Rhythm
Pat-
tern",
the
other
is "Writing/Playing
a Rhythm
Track".
The former
describes
the
writing of
in-
dividual
bars
into computer
memory,
to be
played later,
while
the latter
discribes
writing
the
entire rhythm
track of
a
piece of
music
into
computer
memory
.
which
also
may be
played
later.
The
TR-606
can
do all
this, and more,
so eacti
switch
has at least two functions.
Furthermore,
adjacent
Rhythm
Patterns
may be
"chained"
together
into single,
more
complex
patterns, for
divisions
as
small as slxty-fourtti
notes,
or for
more
complex lime
signatures.

positions give
a maximum of
seven
dif-
ferent
compositions of
64 bars each
and one
ot
256
bars,
and can be
chained
together
in various
combinations for
extended
compositions
of up
to
256 bars each.
A programmable
D.C.
BAR
allows you
to pro-
gram the
final bar of
a
Track
composition
to
begin again
at
the
first bar.
The
TR-606 can be
connected
to
a variety of
digital
sequencers,
synthesizers
and
other
devices
for
synchronized
rhythmic
control
of
sound,
expanding
its live
performance,
corn-
posing and
recording
applications.
The
TR
606
is exceptionally
compact,
and for
maximum
portability
features
battery opera-
tion
for all
functions
including
a
self-contained
Headphone
Amplifier
for
monitoring
through
any Stereo
Pleadptione.
For
extended
battery
life, a
socket
is included on
the back
panel
for
connection to
an optional
Boss
ACA Battery
Eliniinator.
The
TR-606 owner's
manual has
two courses
consisting
of a Basic
Course and an
AdvanceiJ
Course,
because these
unique
functions should
be
completely
understood.
