You can program a new song on an external sequencer, using
Pa900 as a multi-timbral expander.
Connections and settings
In order to connect Pa900 to a computer, you need a computer
with either a MIDI interface or a USB port.
In case of an USB connection, install the Korg USB MIDI
Driver, as explained in "Installing the Korg USB MIDI
Driver" on page 428.
Connect Pa900 and the computer either via the USB
Device port, or via the MIDI ports and a MIDI interface, as
shown in the following diagram.
Activate the "MIDI Thru" function on the external
sequencer. Please refer to the sequencer's user manual.
On Pa900, select the "Extern.Seq. " MIDI Preset. You can do
this by going to the "MIDI: General Controls" page of the
Global mode. Note that this MIDI Preset will be remain
unchanged even when the instrument enters standby.
Go to the "MIDI: General Controls" page, and uncheck the
"Local Control On" parameter (see page 259). This is called
the "Local Off status".
Note: Settings may change when new Global data is loaded
from disk. To protect settings from loading, use the Global
Protect function (see "Global Protect" on page 254).
Press SEQUENCER to go to the Sequencer mode.
Play the keyboard. Notes played on the keyboard will go
from the MIDI OUT of Pa900 to the MIDI IN of the com-
puter/MIDI interface (or from the USB port of Pa900 to the
USB port of the computer).
Notes generated by the computer (i.e. a song played by its
sequencer) are sent through the MIDI OUT of the MIDI
interface to the MIDI IN connector of Pa900 (or from the
USB port of the computer to the USB port of Pa900).
Connecting Pa900 to an external sequencer
The Local Off
When Pa900 is connected to an external sequencer, we recom-
mend you to set the Pa900 in Local Off mode (see "Local Con-
trol On" on page 259) to avoid that the notes are simultaneously
played by the keyboard and by the MIDI events sent by the
When Pa900 is in Local Off, the keyboard of Pa900 transmits
data to the external sequencer, but not to the internal sound gen-
eration. The sequencer will receive notes played on the keyboard
of Pa900 and will send them to the selected track of the song.
The track will then transmit data to the internal sound genera-
tion of Pa900.
Note: In order to send data to the sound generation of Pa900, the
"MIDI Thru" function must be activated in the external sequencer
(normally active; the name may be different according to the type
of sequencer). For more information refer to the instructions man-
ual of the sequencer.
The song that is played back by the sequencer can select Pa900
Sounds through the MIDI messages Bank Select MSB, Bank
Select LSB (bank selection, two messages), and Program Change
(Sound selection). For a list of Sounds and MIDI values, see
"Sounds" on page 318.
A suggestion for those who program songs on computer: even
though it is not mandatory, for a wider compatibility you should
set the bass on channel 2, melody on channel 4, drum kit on
channel 10, controls for an harmonizer on channel 5.
