Do not connect two or more GW-7 units to one computer via USB. The system
will not operate correctly with such connections.
Procedure
1. Turn on the power of your computer.
2. Turn on the power of the GW-7.
3. Use a separately available USB cable to connect the GW-7 to your
computer.

SYSTEM SOFTWARE
UPDATING INSTRUCTIONS
The GW-7 uses flash memory to store its program Rom. The flash memory
updater (control program) is stored in the updater block of the flash memory.
The data for the update is normally provided as SMF data (p000**.mid) or
Binary data (GW7*.BIN).
Connect a sequencer that is able to play back SMF data (e.g., the MC-80) to the
GW-7, and load the data into the GW-7 to update its program or connect a
computer to GW-7 via a USB, and load the data into the GW-7 to update its
program.
After you update the system, you will need to perform the Factory Reset.
Once this will also reset the user data, you must back up the user data
beforehand. (Refer to “Saving and loading data”)
Turn around time of updating about 40 minutes(by MIDI connecting) or 15
minutes(USB connecting).
UPDATE BY MIDI CONNECTING
Items Required
• Sequencer that is able to play back SMF data (e.g., MC-80; a sequencer
that has Chain Play capability is ideal)
• MIDI cable
• UPDATE DATA FOR SERVICE CD-ROM (#17041619) EXCEPT FOR
CHINA
• UPDATE DATA FOR SERVICE CD-ROM (#17041620) FOR CHINA
The procedure of system software
update
1. Connect the MIDI from your external sequencer’s MIDI OUT to the GW-
7’s MIDI IN.
If you are using a sequencer with Chain Play capability, make settings so
that you can chain-play the SMF files.
2. While holding down the [USER] button and [SONG] button, turn on the
power. (Continue holding down the buttons until the following screen
appears.)
I
3. Press the [PIANO] (1:MIDI) button. The display will indicate to wait to
receive MIDI data.
4. When the GW-7 indicates that it is waiting to receive MIDI data, play
back all of the “.mid” files from the GW-7 UPDATE DATA FOR SERVICE
in numerical order.
While the GW-7 is receiving MIDI data, the “Waiting” indication will change
to “Receiving.” When the data of one file has been received, the indication will
change to “Waiting”; you can then play back the next file.
The update process will be easier if you use a sequencer that has Chain Play
capability, such as the MC-80.
5. When the update is completed, the following screen will appear and the
(SPLIT) and (DUAL) LED will blink.
