Controlling the DDK-7 from an External Device
You can use an external MIDI keyboard or sequencer to remotely play the sounds of
your DDK-7 and change its Registrations. (You will need to set the MIDI transmit
channels of the MIDI keyboard to match the fixed receive channels on your DDK-7.)
MIDI terminals are automatically disabled when the USB TO HOST terminal is used.
Connecting USB storage devices or USB-LAN adaptor
Using the USB TO DEVICE terminal(s), you can connect USB storage devices for
saving your DDK-7 data, and/or a USB-LAN adaptor for direct connection to the
Internet.
Compatible USB devices
You can connect a single USB-LAN adaptor and up to two USB storage devices (such
as USB flash memory) to the USB TO DEVICE terminal(s). Before purchasing a USB-
LAN adaptor or USB storage devices, please consult your Yamaha dealer, or an
authorized Yamaha distributor for advice, or see the Yamaha website (http://
www.global.yamaha.com/).

NOTE
If necessary, use a USB hub.
Only self-powered (battery or
external power supply) types
can be used. USB hubs of up
to one levels can be used.
Precautions when using the USB TO DEVICE terminals
•Never turn the USB device’s power on/off and never plug/unplug the USB
cable when the connected USB storage device is of the self-powered type.
Doing so may result in the operation of the DDK-7 “freezing” or hanging
up.
• While the instrument is accessing data (such as Save, Load, and Delete
operations), do NOT unplug the USB cable, do NOT remove the media
from the device, and do NOT turn the power off to either device. Doing so
may corrupt the data on either or both devices.
