■Connecting the serial port on the computer to the
Clavinova’s [TO HOST] jack..................................................................................
Connect the computer’s serial port (RS-232C or RS-422) to the Clavinova’s
[TO HOST] jack.
In this connection, the Clavinova functions as a MIDI interface. Therefore,
you do not need a special MIDI interface.
●Connection
Use a special serial cable to connect the computer’s serial port (RS-232C or
RS-422) to the Clavinova’s [TO HOST] jack.
● Note for Windows users (regarding the
MIDI driver)
To transfer data via the computer’s serial port
and the Clavinova’s [TO HOST] jack, you need
to install a specific MIDI driver (the Yamaha
CBX driver for Windows). You can download
this driver from XG Library on the Yamaha Web
site.
