MEMORY
In the PLAY
raode,
data already in the memory
is used for performance.
In
this section
we'll describe how
to call out the required
voice
for performance, and how memory
positions can
be
changed without altering
the voice
or
performance
data.

PERFORMANCE MEMORY
& VOICE
MEMORY
What
is
PERFORMANCE MEMORY?
In the DXl the two
channels
of internal
VOICE MEMORY
or
external cartridge VOICE
JIEMORY
are
combined with
the
FUNCTION
raode
jHjffects to form the
complete performance
~oices.
The
PERFORMANCE MEMORY
is
a
memory
in which
the
VOICE MEMORY numbers are
combined with effects and stored.
Channel
A/B
corabinations and the addition
of
effects
can be freely set up and
stored
in the
PERFORMANCE MEMORY.
In
the PLAY mode
complete voices can
be easily selected using
the PERFORMANCE MEMORY switches.
^P.12

When
the DXl is initially shipped,
its
PERFORMANCE MEMORY contains
64
combinations pre-programmed at
the
Yamaha factory, permitting immediate
performance when
the
instrument
is
received.

II memory.
*
Voice
and effect combinations are
stored
in the
PERFORMANCE MEMORY
as
a
number.
The actual voice data {the
EDIT mode parameters) are not
memorized.
•*
The internal RAM (Random Access Memory)
VOICE MEMORY
can be used to store all
EDIT
raode
parameters. When
the
instrument
is initially shipped,
the
VOICE MEMORY contains
32
voices in
each channel, A and
B,
for
a
total
of
64 voices.
*
The
5
ROM (Read Only Memory) cartridges
provided contain original Yamaha
voices and effect
data.
*
The two DXl VOICE ROM CARTRIDGES each
contain
64
voices for
a
total
of
128
voices.
Each cartridge has two sides:
I
and
II. The I/II switch
is used
to
select the desired
side.
Side
I
contains
the same
voices
as are
initially stored in
the instrument's
internal memory, and side
II contains
different voices.
Be sure to
switch
to the
desired side before plugging
a
cartridge into
the DXl.
^p.13
*
The two DX7
VOICE ROM CARTRIDGES
provided also contain
64
voices each
for
a
total
of 128 voices.
*
The
PERFORI'IANCE ROM CARTRIDGE contains
the same
64
effect "settings"
as the
DXl
internal PERFORMANCE MEMORY.
When
this cartridge
is inserted into
the
pxl, the data it
contains
is
called
into the internal memory, combined
with
the desired voice
data and used
rCor
performance.
Up to 32 original voices {voice
parameters)
or 64 original effects
(function parameters) can
be stored in
the RAM cartridges.
When
a
RAH
cartridge
is plugged into the
DXl,
original data
can be
freely called
from
it.
The
RAM cartridges
are initially
shipped
set up with the VOICE MEMORY
(voice parameter) format.
To use the
RAM cartridge for PERFORMANCE MEMORY
storage (function parameters),
use the

function.
The BUFFER
The buffer is
a
special separate memory
into which DXl data
is
called from
memory
for performance
or editing, A
buffer
is provided
for the
PERFORMANCE
MEMORY and
the VOICE MEMORY.
When
a
memory number
is selected, the data
corresponding to that memory number
is
read into
the buffer (fig. 10),
In the
PLAY mode data read into the
VOICE EDIT BUFFER and PERFORMANCE EDIT
BUFFER
is
used as is for performance.
In
the EDIT mode VOICE MEMORY data
is
read into the VOICE EDIT BUFFER
for
editing.
