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. (Keep in mind that Song Filer cannot be used to transmit data from the PSR-K1 to a computer. Also, when you download songs to SmartMedia card, make sure that the write-protect seal is not affixed to the card.)

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.) NOTE • If you can't get any sound out of the instrument, this may be the most likely cause. Playing the keyboard results in no sound when Local is set to OFF. PSR-K1 Owner's Manual 67
