during audio playback.
Use the following procedure to set graphic acceleration to "None."
1.
In the Windows Control Panel, double-click [Display] to open the
Display Properties dialog box, and click the [Settings] tab.
2.
Click [Advanced] to open properties, and click the [Performance] tab.

In Graphics, move the Hardware acceleration: slider to None, and click
[OK].
4.
In the Display Properties dialog box, click [OK] to close the dialog box.
Then restart your computer.
• Noise is heard in the line input
If a MIDI sound module and the UA-1A are connected via USB to the same
computer, and the output of the MIDI sound module is connected to the line
input jacks of the UA-1A, noise from the computer may enter via the MIDI
sound module and be heard from the UA-1A. In such cases, use a self-
powered hub to connect the MIDI sound module and the UA-1A in parallel, or
connect the MIDI sound module via the serial interface or MIDI interface.
• Noise may be heard if you record and play back simultaneously.
If you record and play back simultaneously, the playback may be interrupted
depending on the performance of the system, and this may be heard as noise.
However since priority is given to recording, the recorded data will not be
lost.
• This problem may be solved by properly grounding the chassis of
your computer, or the ground prong of the plug on the AC power
cord that was supplied with your computer. Also, make sure that
there are no devices nearby that emit a strong magnetic field, such
as a television or a microwave oven.
• Are a large number of audio devices connected?
If a large number of audio devices are connected, noise may occur. Do not
connect audio devices that you are not using.
