Clavinova CLP-955
Owner's Manual

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.
"The Clavinova-Computer Connection," a document describing what you can do with your Clavinova and a personal computer and how to set up a Clavinova-Computer system is available online as a PDF document (in English) at the following internet address:

NOTE
When connecting the Clavinova to a personal computer, first turn the power to both the Clavinova and the computer OFF before connecting the cable and setting the HOST SELECT switch. After connecting the cable and making the appropriate HOST SELECT switch setting, turn the power to the computer on first, then turn on 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. 
"HST" will appear in the display if the host computer is not turned on, the connecting cable is not properly connected, 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".

Connecting to an Apple Macintosh Series Computer
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.

NOTE
If your system doesn't work properly with the connections and settings listed above, your software may require different settings. Check your software operation manual and if it requires a 31,250 bps. data transfer rate, set the HOST SELECT switch to "PC-1".
When using the TO HOST terminal to connect to a personal computer using Windows, a Yamaha MIDI driver must be installed in the personal computer.

Using a USB Interface (such as the Yamaha UX256)
Connect the USB interface (Yamaha UX256 or equivalent) to your computer using a USB cable. Install the driver software supplied with the interface (or other appropriate driver software) on your computer according to the supplied instructions. Connect your instrument to the USB interface using either a standard Macintosh 8-pin system peripheral cable or MIDI cables. Refer to the manual supplied with your USB interface for details.

Factory Preset Recall
All dual mode, split mode, reverb, effect, touch sensitivity, tuning settings, and the settings affected by the Backup Functions can be restored to their original factory preset values by holding the C7 key (rightmost key on the keyboard) while turning the [POWER] switch ON. This also erases all recorder data, and sets all Backup on/off settings (F9) to "OFF".
NOTE
he factory setting list is found on page 42.
