Oberheim OB-XA - Page 5

CONGRATULATIONS!
You
have
just
purchased
a
most
powerful
tool
for
synthesizer
performance
and
composition.
The
Oberheim
OB-Xa/120
Polyphonic
Synthesizer
is
the
latest
result
of
the
evolutionary
philosophy
of
product
development
at
Gberheim
Electronics.
The
OB-Xa
is
an
update
of
the
OB-X,
which
was
originally
introduced
in
June
1978.
Since
the
introduction
of
the
OB-Xa
in
December
1980,
numerous
changes
and
improvements
have
been
made.
These
include
the
expansion
of
program
memory
from
32
Programs
to
120
Programs;
doubling
of
the
Split
and
Double
Programs;
the
addition
of
Square
Wave
Modulation
with
the
modulation
lever;
a
quieter
output
section;
an
improved
Auto-Tune
circuit
which
will
turn
off
out-of-tune
voices;
improved
Cassette
Interface;
and
the
latest
update,
the
addition
of
several
Portamento
modes,
which
present
additional
new
possibilities
for
sound
composition.
The
OB-Xa
is
complemented
by
the
DSX
Digital
Polyphonic
Sequencer,
which
stores
notes
and
patch
changes
in
much
the
same
way
that
the
0B-Xa
stores
sounds,
digitally
In
fact,
the
OB-Xa
is
a
complete
microcomputer
system,
with
microprocessor,
memory,
cassette
data
storage,
and
most
of
all,
the
computer
program
or
"software".
Yet
the
OB-Xa
has
been
designed
to
be
used
by
the
beginning
and
professional
synthesist
alike.
So,
work
with
your
new
synthesizer;
experiment
with
it.
You'll
find
that
the
OB-Xa
gives
you
more
control
over
your
sound
than
ever
before.
And
isn't
more
control
what
synthesizers
are
all
about?
