Installing the ASIO driver
You must install the MIDI driver even if you will be using
only audio on the UA-20. Be sure to install the MIDI driver
before you install the ASIO driver.
This section explains how to install the ASIO driver that
allows the UA-20 to be used by your sequencer software or
audio editing software. For details on installation and settings
of the ASIO driver, be sure to also read the Driver E–ASIO
Driver–Setting ASIO Driver-E.HTM document on the
CD-ROM.
In Advanced mode, the UA-20 cannot play back audio data
from the Macintosh's sound manager (such as audio CDs and
alert sounds).
The ASIO driver of the UA-20 supports the following audio
input/output channels.
• Audio input .......24/16 bit1 stereo ch. (2 monaural chs.)
• Audio output.....24/16 bit1 stereo ch. (2 monaural chs.)
Here we will explain how to install the ASIO 1.0 16 bit-
compatible driver.
If your ASIO-compatible software supports ASIO 2.0 or recording/
playback of 24 bit audio data, using the following drivers will provide a
higher quality environment.

ASIO (Steinberg Audio Stream
In/Out Interface)
This is an audio interface
standard promoted by the
Steinberg Corporation. When
the UA-20 is used with ASIO-
compatible software, the
synchronization precision will
be improved, allowing a more
sophisticated music
production environment.
