When this instrument and a computer are connected with a USB cable, MIDI communication can be performed. The
explanations here cover the settings necessary for performing MIDI communication between both devices.
For instructions on how to connect this instrument to the computer, refer to the "Computer-related Operations"
downloadable from the Yamaha Manual Library.
MIDI Transmit/Receive Channel Selection
In order to perform MIDI communication between this instrument and a computer, it is
necessary to match the corresponding MIDI transmit and receive channels. By setting the
MIDI transmit channels on this instrument, the setting of the keyboard or pedal performance
or the program change can be transmitted over the channel number corresponding to a
specified channel on the computer. By properly setting the MIDI receive channels on this
instrument, only data of the specified channel will be played back in the MIDI data received
from the computer.
Setting the Transmit Channel
While holding down [DEMO/SONG] and [PIANO/VOICE], press the C1–E2 keys.
Setting the Receive Channel
While holding down [DEMO/SONG] and [PIANO/VOICE], press the C4–F5 keys.
Local Control ON/OFF
"Local Control" refers to the fact that, normally, the keyboard of the instrument controls its internal tone generator,
allowing the internal voices to be played directly from the keyboard. This situation is "Local Control On," since the internal
tone generator is controlled locally by its own keyboard. Local Control can be turned off as desired, so that the keyboard
of the instrument does not play the internal voices.
While holding down [DEMO/SONG] and [PIANO/VOICE], press the C6 key. Pressing the
C6 key repeatedly toggles between Local Control On and Off.
