message for each C-lOO/C-220 instrument used.
When
recording
a
part
which uses an
external
device such as the C-100
or
C-220, send the Program
Change for the desired sound to the PR-300 before
any notes are played. Make sure the Program Change
is sent after the Count-In measures.
(If
you want to
have the sound play on the
fIrst beat
of
the sequence,
you may want to start the sequence on measure 2 and
have
the
Program
Changes
for
external
devices
recorded in measure 1).
There are two different ways to send a Program
Change from a C-100
or
C-220. The two procedures
are outlined in the Owner's Manual for the C-100 and
C-220 (see the sections entitled "Sending a Program
Change"
and
"Automatic
Program
Change
and
Control Change Transmission Feature").
When the Send Channel
Can't
Be
Changed
...
In the previous example, the send channel
of
the
keyboard controlling the PR-300 could be changed,
making
it
easy
to
use
different
instruments
for
different parts. As a single MIDI channel can control
only one instrument, another MIDI channel must
be
used whenever you want to add another instrument to
your sequence.
Some
MIDI
devices
(such
as
MID.I
Phase
I
instruments)
don't
allow
you
to
change
the
send
channel used.
If
the keyboard you are using doesn't
allow you to change the send channel, you will need
to follow another
procedure
to use multiple
MIDI
channels.
One
of
the
most
common
solutions
to
this
situation is to use a
MIDI
channel filter. A
MIDI
channel
filter
is
a
MIDI
accessory
which
shifts
infonnation from one MIDI channel to another MIDI
channel.
By
inserting
the
MIDI
channel
filter
between the MIDI OUT jack
of
the keyboard and the
MIDI
IN
of
the PR-300, you will
be
able to generate
information on multiple channels (even though your
controlling keyboard only sends on one channel).
MIDI channel filters should be available from a
local music store.
