NOTE:.
If
you
have
a voice
set
programmed on
a
Yamaha DX21
Digital
Programmable
Algorithm
Synthesizer, these voices
can be
transferred
from
data cassette
to
the
DX100.
Of
course, since the
DX100
has
24
voice memories
while the
DX21
has
32, using the
DX100
cassette
LOAD
operation
will
load only the
first
24
voices
of
the
DX21
32-voice
set into the
INTERNAL
memory. The
other voices (25-32)
can be
loaded using the DX1 00
LOAD
SINGLE
function.
The
voice numbers
for voices
25
through
32
are
accessed by
pressing the
STORE, FUNCTION,
EDIT,
INTERNAL
PLAY, and
BANK A-D
buttons.

This function turns the DX100
MEMORY
PROTECT
function on
or
off.
When
on,
the
INTERNAL
RAM
voice
memory
cannot be
altered using the
STORE
or
CAS-
SETTE
LOAD
functions.
The
MEMORY
PROTECT
function does
not
affect
the voice
edit buffer, so the INIT VOICE,
RECALL
EDIT,
and CASSETTE LOAD
SINGLE
functions
will operate
whether
MEMORY
protect
is
on
or
off.
When
this
function
is
called, the
LCD
will
read
either
"M.
Protection"
or
"M.
Protect:off,"
according
to the current
state of the
MEMORY
PROTECT
function
(MEMORY
PROTECT
is
automatically turned
ON
every time the
main power
to
the
DX100
is
turned ON). The -1/+1
buttons and
DATA
ENTRY
control are used
to turn
MEMORY
PROTECT
on
or
off.
