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.

• When a song is playing

 

 

• From the File Control display

 

• If a SmartMedia card is not inserted

Precautions concerning USB

Do NOT turn the power on/off or connect/disconnect the USB cable in any of the following conditions. Doing so may cause the com- puter to hang up or freeze, stop the current operation or function in the musical instrument, and/or result in all data in the SmartMedia card being lost.

• While the device is being recognized or while the driver is being loaded

• While starting or stopping the operating system

• While the computer is in stand-by mode or hibernating

• While a MIDI application is operating

• While data is being transferred

 

Also, make sure to avoid the following. Problems such as those mentioned above may occur.

Turning the power on/off too often, or connecting/disconnecting the cable too frequently

Changing to a power-save mode or resuming from stand-by while transferring MIDI data

Connecting or disconnecting the cable while the power of the musical instrument is on

Turning the power on or off, starting the computer, or installing the driver while data is being transferred

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.)

If you can’t get any sound out of the instru- ment, this may be the most likely cause. Playing the keyboard results in no sound when Local is set to OFF.
