the front of the unit.
NOTE
The same signals are output from both the 1 and 2 jacks
of the US-4x4.
CAUTION
Before connecting headphones, minimize the volume with
the PHONES knob. Failure to do so might cause sudden loud
noises, which could harm your hearing or result in other
trouble.
MIDI connections
Connect sound modules, keyboards, synthesizers, drum
machines and other MIDI devices to the unit in the following
manner.
iiIf you want to monitor sound from a MIDI device, connect its
outputs to this unit's LINE IN or use in external mixer.
iiYou can also use the MIDI IN and MIDI OUT connectors
on the back of the unit to send and receive MIDI timecode
(MTC). By doing this, you can use an application that
supports MTC to synchronize a multitrack recorder (MTR) and
MIDI devices.
CAUTION
•The MIDI IN and USB indicators might stay lit even after
the connected computer is shut down. This is because some
computers continue to provide power through USB cables
even after being shut down.
•The MIDI IN indicator lights when the unit is receiving MIDI
data through the MIDI IN connector. If you connect a device
that sends MIDI active sensing messages, this indicator will
blink constantly. In order to avoid this, disable MIDI active
sensing on the connected device.
• When using Windows Media Player, if the “Sound and Audio
Devices Properties” Control Panel “MIDI music playback
(default device)” is set to “Microsoft GS Wavetable SW
Synth”, you will not be able to hear MIDI performances
through this unit's LINE OUT [BALANCED] or PHONES
jacks.

6 – Using the Settings Panel
3Buffer Size item (Windows Only)
The driver for the unit stores the audio input and output
signals transferred to and from the computer temporarily in
a buffer.
This buffer size can be adjusted.
Smaller buffer sizes result in less audio signal delay (latency),
but require high-speed processing by the computer.
If the processing cannot keep up, for example, due to other
system operations, clicking and popping noises might occur
and the audio signal might even drop out.
Increasing the buffer size will stabilize operation and
suppress negative effects on audio signals, but the delay in
audio signals sent to the computer will increase.
You can use the slider on the panel to adjust the buffer size,
according to the use conditions.
Use the slider to select fixed values that increase from left to
right (64, 128, 256, 512, 1024 and 2048 samples).
4Audio Input items
Turn input on/off for each channel separately.
iiTurn an input on by putting a check in its checkbox.
When an input is on, signals on that channel will be
input.
iiTurn an input off by removing the check from its
checkbox . When an input is off, signals on that
channel will not be input.
