The
S900
is
very
flexible
in
its
MIDI implementation.
A
keygroup
can be assigned
to
any one
of
the
1
6 MIDI
channels. This allows
for
MIDI
mono mode
operation,
where each sound
is
driven
by
its
own
channel. This
mode
is
very popular
for
use
with
MIDI
sequencers and
guitar
synthesizers.
A
compete
discussion
of
MIDI
is
beyond
the
scope
of this
manual;
Akai
suggests
the
book
"MIDI For
Musicians"
(written
by
Craig
Anderton
and
published
by
AMSCO,
a division
of
Music
Sales)
for
those
who
want
to
learn
more
about
MIDI.
MIDI
STATUS
The LCD's
right
side
shows
the
keygroup's MIDI channel as
ini-
tially
set
on
MIDI
Page
01
("all"
for
Omni mode
on, or a
channel
number
from
1
to
16
if
that
was
specified
instead).
MIDI
CHANNEL
(offset)
Point
arrow
at
"MIDI channel
offset."
Use
CONTROL
or
enter a
two-digit
number
with the
0-9
keys
to offset
the
channel
shown
in
the
LCD
by
to
1
5.
Example:
If
the
MIDI channel
specified
on
MIDI
Page
01
is
4,
then
adding an
offset
of
1
for
a
keygroup
means
that particular
keygroup
will
respond
to
MIDI data
coming
in
over
channel
5 instead
of
channel
4.
Adding an
offset of
2
would
set the
keygroup
to
receive
on MIDI channel
6.
The
LCD
will
update
the
channel
number
to reflect
any
offset
you
add.
Offsetting a
channel
beyond
the
number
16
will
de-assign
that
keygroup
from responding
to
any
MIDI
information
on any chan-
nel
and
the
LCD
will
show "NONE."

recommended
for
