● Channel Messages
This instrument is capable of handling 16 MIDI channels simultaneously—meaning it can play up to sixteen different instruments
at the same time. Channel messages transmit information such as Note ON/OFF, Program Change, for each of the 16 channels.
● System Messages
This is data that is used in common by the entire MIDI system. System messages include messages like Exclusive Messages that
transmit data unique to each instrument manufacturer and Realtime Messages that control the MIDI device.
The messages transmitted/received by the instrument are shown in the MIDI Implementation Chart on page 94.
Connecting to a computer
Connecting this instrument to a computer enables a wide range of powerful and useful musical possibilties. You can transfer MIDI data
back and forth with your computer for music recording/playback, and with the special Song Filer software (contained in the included
CD-ROM), you can copy data from your computer to SmartMedia card.
Connect one end of a USB cable to the USB terminal on the rear panel of this instrument, and the other end to the USB terminal on
your computer. You’ll also need to install the USB-MIDI driver (also in the included CD-ROM) to your computer. For details, see the
“Accessory CD-ROM Installation Guide” on page
71.
MIDI settings
These settings determine how the instrument sends, receives and responds to MIDI data.
■ Local ON/OFF (Local)
This determines whether the internal tone generator sounds (ON) or not when you play the keyboard.
• ON (Local ON) ........... The normal performance condition; playing the keyboard plays the voices
of the instrument.
• OFF (Local OFF)........ In this condition, playing the keyboard has no effect on the voices, harmony
or accompaniment of the instrument. However, your keyboard performance
is transmitted as MIDI data via the USB connection, and the instrument
responds to data received via the USB connection.
Local ON/OFF can be set from the Local page of the FUNCTION display. (See page 79.)
