3 Operation
Note:
① USB
The USB connector is plugged the USB connection of the computer
and power supply.
② Indicator
It is a 2-color indicator, red for power indicator and green for signal
indicator.
3.1 Power Supply
The product is powered by USB port.
After starting your computer, connect the product to the computer
USB cable.
If it is the first time the product is connected to the computer, the
Windows will automatically install the device driver. Follow the
Wireless MIDI Interface User’s Manual
12
instructions for driver installation. When asked for the device driver,
please let the Windows automatically search the driver. When the
installation is completed, the product will show in the system device
list as the “USB Audio Device”.
If it is the first time the product is connected to the Macintosh, the
Mac OS will automatically install the device driver. When the
installation is completed, the product will show in the “MIDI & Audio
Setup” as the “WIDI-XU”.
If the device is already installed but disabled, just enable it, and the
power indicator (red) is on.
3.2 Wireless Connection
When you plug the product to the computer USB port and the device
driver is properly installed (enabled), the product will automatically
search for another available WIDI device to make wireless connection.
When the wireless connection is established, the signal indicator
(green) is on.
3.3 Signal Route
The route mode is: USB Ù RF。
Note:
a): WIDI-XU is used as the receiver to receive the wireless MIDI data
from the sender such as another WIDI-XU, and transfer the MIDI
data to the computer. In your music software, please choose “USB
Audio Device” as the MIDI input device.
b): WIDI-XU is used as the sender to get the computer MIDI data,
then convert them to wireless signal and send them out for other
WIDI devices to receive. In your music software, please choose
“USB Audio Device” as the MIDI Output device.
Wireless MIDI Interface User’s Manual
13
3.4 Channel Selecting
Each WIDI-XU can be set to one from 64 channels for MIDI data
transfer. Suppose one pair of the WIDI devices use one channel, up
to 32 pairs of WIDI devices can be used at the same place.
The channel selecting of WIDI XU is something like WIDI-X8, you
can manually set the channel, automatically synchronize to another
channel or auto find and set channel. To do so, you need to send
system command to the WIDI-XU via MIDI messages.
The system commands are essentially standard MIDI system
exclusive messages (sysx, F0 … F7). You can edit and sent those
sysx in your music software like Cakewalk, etc. See appendix 1 for
more about the MIDI system exclusive messages.
There is another simple way to send the system commands, that is,
you can use the WIDI Control.EXE program, which you can download
from the CME international website.
Selecting A Channel
System command data: F0 00 20 63 00 07 02 02 10 nn F7
Set the WIDI-XU to channel nn, nn is a hex number from 01 to 40,
in dec the data range is 1-64, see appendix 2 for more detail.
WIDI Control operation: Select a channel, then click “Set Channel”.
Auto Finding
System command data: F0 00 20 63 00 07 02 02 10 50 F7
By using this command, the WIDI-XU will automatically search and
find an available WIDI device and establish communication. The
signal indicator (green) will be on when the communication is
established.
WIDI Control operation: Click “Auto Search”.
Auto Changing To Another Channel
System command data: F0 00 20 63 00 07 02 02 10 5F F7
By using this command, the WIDI-XU will automatically search and
find an available channel, and set itself and another WIDI device to
this channel. When the two WIDI devices change to the new channel,
both the signal indicators (green) will be on.
WIDI Control operation: Click “Auto Change”.
Enable RF
System command data: F0 00 20 63 00 07 02 02 10 6F F7
This command will enable the wireless transmission.
WIDI Control operation: Click “RF ON”.
Disable RF
Wireless MIDI Interface User’s Manual
14
System command data: F0 00 20 63 00 07 02 02 10 60 F7
This command will disable the wireless transmission.
WIDI Control operation: Click “RF OFF”.
Note:
For proper communication, each pair of the WIDI devices
should use the same channel, and different pairs use different
channels.
The WIDI system supports up to 32 pairs of WIDI devices to be
used at the same place. When several pairs of WIDI devices are
used at the same place, please use the channel number 1-32.
An available WIDI device means this WIDI device dose not
establish communication with another one.
WIDI devices include WIDI-X8, WIDI-XU, WIDI-EK, etc.
3.5 Removal Of The Product
If you finish using the product, please remove it from your computer
in the proper way as below:
z Close the music software that uses the product.
z Stop the “USB Audio Device” from windows device manager.
z Unplug the product from the computer。
4 Automation
4.1 Automatic Communication Establishing
z Automatic establishing communication when powered on.
When the product is powered on, it will automatically search and
find another available WIDI device and establish communication.
When the communication is established, the signal indicator
(green) will be on.
z Automatic establishing communication when channel changed
When the channel is changed (either manually or automatically),
the product will automatically establish communication. When the
communication is established, the signal indicator (green) will be
on.
Wireless MIDI Interface User’s Manual
15
4.2 Automatic Notes Off
In either one of the following cases, the system will automatically
send the “All Notes Off” and “All Sound off” MIDI messages to stop
the sound from the tone generator.
z Bad signal with data loss.
z During the communicator the sender is switched off.
z Radio channel changed.
4.3 On-line Detection
After powered on the WIDI system will automatically detect the
on-line status. The green indicator will show the communication
status.
5 Notice
z Before launching Cakewalk or other music software, make sure
the product is properly connected the computer, otherwise the
music software cannot find the MIDI device.
z Close the music or audio software before removing the product.
z Stopping the product in the OS before unplug it from the
computer, which is better then unplugging it directly.
z Remove all the obstacles and un-wanted RF devices near the
product.
z When the signal indicator (green) flashes, it means there is
interference, and if the indicator flashes fast, it means too much
interference stops the communication. To get a good
communication, the green indicators on both sides should be
on.
z If many pairs of WIDI products are used at the same place,
please limit the channel settings to 1-32 for best communication
quality.
