Changing the driver set­ting (MIDI Patch Screen)

You can change the assignment of I/O connectors on the UX256 and port numbers
selected from the computer.
Sequence software transmits and receives MIDI signals to and from the UX256 via the
driver (page 13). The UX256 is equipped with six MIDI IN/OUT terminals and two TO
TG terminals. You specify the I/O ports of the UX256 to control from the computer’s
sequence software. At this time, changing the driver setting enables you to change
these I/O assignments without re-patching the cables.
For example, you can transmit an identical MIDI signal to multiple ports or transmit
layered MIDI signals from multiple ports to a single port. Also, you can directly route
MIDI signals from MIDI IN to MIDI OUT.
The following table shows the assignment of the port numbers and I/O ports. With the
default settings, the port number matches the computer’s port number.

output port. The left column shows the computer’s output ports (OUT 1-16), and the
top column shows the UX256’s output ports (1-16). With the default settings, ports
with the same number are connected to each other. However, you can change this
setting by checking the check boxes.

If you check multiple check boxes vertically, MIDI signals from multiple output ports
on the computer are merged and transmitted to one output port on the UX256. If you
check multiple check boxes horizontally, a MIDI signal from one output port on the
computer is distributed to multiple output ports on the UX256.

NOTE

See page 24 for more information on the relationship between the UX256’s
I/O ports and the port numbers.

• Routing MIDI signals from the computer’s output ports 1, 2, and

column shows the UX256’s input ports (1-8). With the default settings, ports with the
same number are connected to each other. However, you can change this setting by
checking the check boxes.

If you check multiple check boxes vertically, a MIDI signal from one input port on the
UX256 is distributed to multiple input ports on the computer. If you check multiple
check boxes horizontally, MIDI signals from multiple input ports on the UX256 are
merged and transmitted to one input port on the computer.

NOTE

See page 24 for more information on the relationship between the UX256’s
I/O ports and the port numbers.

• THRU output of MIDI signals (MIDI IN → MIDI OUT)

You can route MIDI signals received at the input port(s) of the UX256 directly to the
output port(s) of the UX256 (this is called THRU output). This routing is useful when
you wish to route MIDI signals from a MIDI keyboard directly to a tone generator. The
left column shows the UX256’s output ports (1-16), and the top column shows the
UX256’s input ports (1-8). To enable this function, check the “Thru ON/OFF” check
box in the lower right corner of the screen.

If you check multiple check boxes vertically, a MIDI signal from one input port on the
UX256 is distributed to multiple output ports on the UX256. If you check multiple
check boxes horizontally, MIDI signals from multiple input ports on the UX256 are
merged and transmitted to one output port on the UX256.

NOTE

• See page 24 for more information on the relationship between the
UX256’s I/O ports and the port numbers.

• For Macintosh, this function is valid only when the MIDI Patch screen or
sequence software is running.

• Routing MIDI signals directly from MIDI IN 2 to MIDI OUT 3

First check the “Thru ON/OFF” check
boxes on the lower right corner of the
screen. Then check the check box as
shown on the right, and click [OK] to
enable the setting.
