What is a driver?

A“driver” is software that transfers data between the

UA-20 and application	Application	USB port
software running on your
computer, when your	USB	USB cable
computer and the UA-20	driver
are connected by a USB	Computer
cable. The driver sends		UA-20
data from your

application to the UA-20, and from the UA-20 to your application.

Advanced mode and Standard driver mode

The UA-20 has two operating modes, Advanced mode and Standard driver mode, and a different driver is used by each mode.

■Advanced mode

The UA-20 will operate in this mode when the rear panel ADVANCE (mode select) switch is turned ON. The special driver included on the CD-ROM will be used, allowing audio to be recorded/played/edited with high quality and stable timing. In Advanced mode, audio signals can be transferred between the UA-20 and the computer at a resolution of 24 bits and sampling frequencies of 44.1 kHz. Select this mode if you are using an application that allows high-quality audio recording/ playback/editing, such as an application that supports 24 bit audio (e.g., the Cakewalk series or Cool Edit) or an ASIO-compatible application (e.g., Cubase VST or Logic Audio). (➝ Installing the special driver (p. 17))

■Standard driver mode

The UA-20 will operate in this mode when the rear panel ADVANCE (mode select) switch is turned OFF. The standard USB audio driver included with Windows will be used. In standard driver mode, audio signals are transferred between the UA-20 and the computer at a resolution of 16 bits and sampling frequencies of 44.1 kHz. Select this mode if you are using an application that uses Window’s own functionality, such as an application that uses the computer’s CD-ROM drive to play back CD-audio, or an application that uses the software synthesizer included with Windows.

The standard driver that is included with Windows does not support ASIO. (➝ Installing the OS-standard driver (p. 31))

* If you want to use MIDI, use Advanced mode.
