Connecting to a Personal Computer
Although the Clavinova can be connected to a personal computer via the
MIDI IN/OUT connectors and a MIDI interface, the TO HOST connector and
HOST SELECT switch allow direct connection to Apple Macintosh or IBM-PC/AT
personal computers for sequencing and other music applications without the
need for a separate MIDI interface.
Connect the TO HOST connector of the Clavinova to the modem or
printer port on your Macintosh, depending on which port your MIDI
software is using for MIDI data communication, using a standard
Macintosh 8-pin system peripheral cable. Set the HOST SELECT
switch to the “Mac” position.
You may also have to make other MIDI interface settings on the
computer side, depending on the type of software you use (refer to your
software owner’s manual). In any case the clock speed should be set to
1 MHz.

•Data transfer rate: 31,250 bps.
NOTE
•When using the [TO HOST] terminal of the Clavinova, first turn the power off on both the Clavinova and the
computer before connecting the cable. After connecting the cable, turn the power of the computer on first, then the
Clavinova.
•When not using the [TO HOST] terminal of the Clavinova, make sure the cable is disconnected from the [TO HOST]
terminal. If the cable is left connected, the Clavinova may not function properly.
•“
HS(
” will appear in the display if the host computer is not turned on, the connecting cable is not properly con-
nected, the HOST SELECT switch is not in the proper position, or the MIDI driver or MIDI application is not active. In
this case, turn the power off on both the Clavinova and the computer, and check the cable connection and the
position of the HOST SELECT switch. Once the connection and HOST SELECT switch position is verified, turn the
power of the computer on first, then the Clavinova, to check if the MIDI driver and MIDI application function properly.
•When the HOST SELECT switch is set to “Mac”, “PC-1”, or “PC-2, no data transfer occurs via the MIDI connectors.
To use the MIDI connectors for connection via a standard MIDI interface, set the HOST SELECT switch to “MIDI”.
