PSR-2100/1100
6Connecting to a Computer (USB terminal, MIDI terminal)
Connecting your PSR-2100/1100 to a computer allows
you to transfer data back and forth between the two and
take advantage of the powerful and versatile music
software available. You can connect the devices in one of
two ways:
■Using the USB terminal
■Using the MIDI terminals
The MIDI terminals cannot be used when the USB
terminal is in use.
An appropriate MIDI application for your computer
platform is required.
For details about the necessary MIDI settings for computer
and sequence software you are using, refer to the relevant
owner’s manuals.

Using the USB terminal

Connect the USB terminal of a computer to the USB
terminal of the PSR-2100/1100 using a USB cable. Make
sure to use a standard USB cable with the USB logo.

Using the MIDI terminals

When using a MIDI interface device installed in the
personal computer, connect the MIDI terminals of the
personal computer and the PSR-2100/1100 with standard
MIDI cables.
• When the computer has a MIDI interface installed,
connect the MIDI OUT terminal of the personal
computer to the MIDI IN terminal.
About the USB driver
You must install the specified USB driver (YAMAHA
USB MIDI Driver) to your computer before you can
transfer data between the computer and the PSR-
2100/1100.
You can download a copy of the YAMAHA USB MIDI
Driver free of charge from the XG Library on the
Yamaha Web site (http://www.yamaha-xg.com/).

USB cable
If you are using a USB cable to connect the PSR-2100/1100 to
your computer, you must connect the USB cable before turning on
the power of the instrument.
Also, do not turn the power of the PSR-2100/1100 on/off while any
application software that uses USB or MIDI is running.
If you turn the power of the PSR-2100/1100 on or off or connect/
disconnect the USB cable in the following states, problems will
occur in the computer system, possibly causing it to “freeze” (hang
up), or causing the PSR-2100/1100 to stop functioning.
• While installing the driver.
• While starting or shutting down the operating system.
• While the computer is in an energy-save or sleep mode.
• When a MIDI application program is starting.
Make sure NOT to perform any of the following operations. Other-
wise, the computer may lock up or the PSR-2100/1100 functions
may be disabled.
•Turning the power on/off, or connecting/disconnecting the cable
too often.
• Shifting to energy-save or sleep mode while MIDI data is being
transferred, or returning from sleep mode.
•Disconnecting/connecting the cable while the PSR-2100/1100 is
on.
•Turning the power of the PSR-2100/1100 on/off, starting up your
computer, or installing the driver while a large amount of data is
being transferred.
CAUTION
• The PSR-2100/1100 will begin transmission a short time after
the USB connection is made.
• When using a USB cable to connect PSR-2100/1100 to your
computer, make the connection directly without passing through
a USB hub.
• Depending on the state of your computer, the operating state of
PSR-2100/1100 may become unstable. Do not use your com-
puter in a way that causes it to enter an unstable state.
When connecting the PSR-2100/1100 to a personal computer, first
turn off the power to both the PSR-2100/1100 and the computer
before connecting any cables.
After making the proper connections and settings, turn on the
power of the computer first, then that of the PSR-2100/1100.
