The Master Page
accesses functions that
are not
remembered as
part of
a
patch,
but
are
used
globally (that is,
in all modes) by the
Xpander
There are two
sets
of
pages
displayed In the
upper
display
are
pages
that affect
the
Xpan
der
in both Single and
Multi
Patch modes.
On the lower
display
are pages
that will appear
only
while
in Single Patch mode.
These
are the
Master Multi Pages
Even while
playing
a
Single
Patch,
you need to be
able
to
select
MIDI channels,
vibrato,
volume,
pan,
etc
. all of the
parameters
normally part of
a
Multi
Patch.
So.
there
is an
extra
Multi Patch
just to
play Single Patches.
This
Master Multi Patch
has
the exact same pages as
a
regular Multi Patch,
except
for the
TRANSposition page
that
is preset to
-12
(an octave
lower.)
The
settings are not
stored
in
a
particular
program
location, but are
remembered
as
a
global setting
for the
machine
These
settings
are stored
on
tape
and can be loaded
separately
by
selecting "LOAD
GLOBAL."
(See
Cassette
Interface.)
Refer to the
specific
Mufti Patch
Page for more
information
(see
Multi Patch
Section.)
Chain is a
scheme
that enables a
series of
Single
and Multi
Patches to
be
accessed
in pro-
grammed
succession
This allows you jump
directly
from
one
particular Single or
Multi Patch
to
another, especially useful
in live performance.
There
are 100
steps within
the Chain.
The Chain
can be
advanced
from
the
Advance
Chain
Input on the
rear
panel, from
the Pro-
grammer Keypad,
or
with the STEP
control
on the
Chain Page

well
