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”.
