When The Send Channel Can't Be Changed - Rodgers PR-300 Owner's Manual

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.
