Frequently Asked Questions - UA-20 EDIROL

How to install the driver under Windows XP?

Disconnect the UA-20. Open System Properties and set the driver signature to 'Ignore'. Insert the CD-ROM and run 'D:\USB_XP2K\SETUPINF.EXE' (or with MME). Connect the UA-20 with the ADVANCED DRIVER switch set to ON. Follow the wizard, choosing installation from a list or specific location, then select the appropriate driver (WDM or MME). Restart the computer.

What is the difference between Advanced and Standard modes?

Advanced mode (ADVANCED DRIVER switch set to ON) uses a special driver provided on the CD-ROM, enabling 24-bit audio and stable timing, as well as ASIO support. Standard mode (switch OFF) uses the standard USB driver of the operating system, limited to 16 bits and 44.1 kHz, without ASIO support. Advanced mode is required for MIDI and high-quality audio applications.

Can I use the UA-20 with ASIO-compatible software?

Yes, in Advanced mode. Install the ASIO driver from the CD-ROM (folder 'Driver E - ASIO Driver') by copying the corresponding folder (e.g., 'UA-20 ASIO1.0 16bit') into the 'ASIO Drivers' folder of your software. Then, select 'UA-20 ASIO 16bit' or '24bit' in the software's audio settings.

How to reduce audio latency?

Open the 'EDIROL UA-20 Driver Settings' dialog via the Control Panel (Windows) or from the ASIO software (Mac). Reduce the 'Audio Buffer Size' (Windows) or 'Buffer Size' (Mac) to the minimum. If the sound breaks up, gradually increase the size until stable operation is achieved.

How to configure the UA-20 for MIDI playback?

Make sure you are in Advanced mode. In the Control Panel (Windows), open 'Sounds and Audio Devices', Audio tab. For 'MIDI playback', select 'EDIROL UA-20 MIDI OUT'. Under Mac OS, install the MIDI driver via OMS or FreeMIDI following the procedure described in the manual, then configure the sequencer software to use the UA-20 as a MIDI device.

What to do if the computer does not detect the UA-20?

Check the USB connection and that the device is powered on. Under Windows, open Device Manager. Remove any unknown device or device marked with an exclamation mark under 'Other devices' or 'Universal Serial Bus controllers'. Restart the computer and reinstall the driver. If the problem persists, try a different USB port or a powered USB hub.

How to use ASIO Direct Monitor?

Open the 'EDIROL UA-20 Driver Settings' dialog and check the 'Use ASIO Direct Monitor' option. This allows ASIO 2.0 compatible software to automatically control direct monitoring, reducing latency during recording. If problems occur, uncheck the option.

Does the UA-20 work under Mac OS X?

No, the UA-20 is not compatible with Mac OS X. The manual indicates support for Mac OS 8.6 to 9.x only. For use with Mac OS X, look for third-party drivers or consider a newer interface.

Can I connect the UA-20 to a USB hub?

Yes, it is possible to use a USB hub, but make sure it is powered (with a power adapter) to supply enough current. Some unpowered hubs may cause instability. If problems occur, connect the UA-20 directly to a USB port on the computer.

How to clean the UA-20?

Disconnect the device. Use a soft, dry cloth to wipe the surface. Never use solvents, alcohol, or abrasive products. Avoid any liquid entering the connectors. Store the device in a dry, dust-free place.

Getting Connected and Installing Drivers (Windows)

If you are using a Macintosh computer, please proceed to Getting Connected and Installing Drivers (Macintosh) (p. 42).

What is a driver?

A "driver" is software that transfers data between the UA-20 and application software running on your computer, when your computer and the UA-20 are connected by a USB cable. The driver sends 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 44.1kHz . 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 44.1kHz . 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.

Switching between Advanced mode and Standard driver mode

If you first install both the special driver and the standard driver, you will be able to switch between Advance and Standard driver modes by operating the UA-20's ADVANCE (mode select) switch.

• In order for the setting of the ADVANCE (mode select) switch to take effect, you must exit all sequencer software and other applications that use the UA-20, and re-connect the UA-20.

Installing the special driver

The installation procedure will differ depending on your system.

Please proceed to one of the following sections, depending on the system you use.

• Windows XP/2000 users. (p. 17)
• Windows Me/98 users. (p. 29)

Windows XP/2000 users

The CD-ROM contains two types of driver for Windows XP/2000.

Normally, you should use the WDM driver.

WDM driver

You should use this driver if you have specified WDM driver mode for SONAR or a similar application. This will provide the highest-quality audio performance.

• It is not possible to use 24-bit audio with applications that do not support a WDM driver mode, such as Cool Edit or Media Player.

MME driver

This driver allows you to use 24-bit audio even from applications that do not have a WDM driver mode, such as Cool Edit. It is not possible to use the MME driver from WDM driver mode of an application such as SONAR.

• It is not possible to install both the WDM driver and the MME driver. You must select one beforehand, and install only that driver. If after installing one of these drivers you decide to change drivers, you must first delete the already-installed driver and then install the new driver. (→ Deleting the special driver (p. 79))
• The WDM driver and the MME driver can be installed using the same procedure.

Getting Connected and Installing Drivers (Macintosh)

If you are using a Windows computer, please proceed to Getting Connected and Installing Drivers (Windows) (p. 16).

What is a driver?

A "driver" is software that transfers data between the UA-20 and application software running on your computer, when your computer and the UA-20 are connected by a USB

cable. The driver sends 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 44.1kHz . Select Advanced mode if you are using an application that is able to record/playback/edit high-quality audio, such as a 24 bit audio application or an ASIO-compatible application such as Cubase VST, Logic Audio, and Metro.

In Advanced mode, the UA-20 cannot play back audio data (audio CDs or warning sounds) from the Macintosh sound manager.

( Installing the special driver (p. 43))

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 MacOS 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 44.1kHz . Select this mode if you are using an application that uses MacOS'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 MacOS. The standard driver included with MacOS does not support ASIO. Note also that the use of Mac OS 8.6 is not supported.

( Installing the OS-standard driver (p. 53))

Switching between Advanced mode and Standard driver mode

If you first install both the special driver and the standard driver, you will be able to switch between Advance and Standard driver modes by operating the UA-20's ADVANCE (mode select) switch.

• In order for the setting of the ADVANCE (mode select) switch to take effect, you must exit all sequencer software and other applications that use the UA-20, and re-connect the UA-20.

UA-20 application guide

This chapter explains the various ways the UA-20 can be connected, and introduces some of its applications.

• To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections.

Basic use

As shown in the diagram, you can connect headphones or monitor speakers, and monitor the playback sound from your application or the sound from the instrument or audio device to which the UA-20 is connected.

Recording a guitar or bass

When you play your guitar along with audio data from your computer to record your performance on a sequencer, only the guitar will be recorded on the computer.

Use the Input volume to adjust the input level.

Check the input level on the application that you are using.

If you turn the input monitor switch to ON, the sound will be output from the headphone jack and the master output jacks.

Recording from a mic

Use the Input volume to adjust the input level. Check the input level on the application that you are using.

If you turn the input monitor switch to ON, the sound will be output from the headphone jack and the master output jacks.

• Howling could be produced depending on the location of microphones relative to speakers. This can be remedied by:

• Changing the orientation of the microphone(s).

• Relocating microphone(s) at a greater distance from speakers.
• Lowering volume levels.

Recording from a keyboard

Here's how you can send a keyboard performance as audio data to your computer, and record it on sequencer software.

The sound that is input to Input jack L(MONO) will be recorded on the left channel, and the sound that is input to R jack will be recorded on the right channel.

Use the Input volume to adjust the input level. Check the input level on the application that you are using.

If you turn the input monitor switch to ON, the sound will be output from the headphone jack and the master output jacks.

Recording an analog signal from an audio device

The sound that is input to Input jack L(MONO) will be recorded on the left channel, and the sound that is input to R jack will be recorded on the right channel.

Use the Input volume to adjust the input level.

Check the input level on the application that you are using.

If you turn the input monitor switch to ON, the sound will be output from the headphone jack and the master output jacks.

Be careful of looped connections

UA-20

Loop Connection

Stereo Set
(cassette player)

If the UA-20 is connected as shown above to a device that outputs ("thru-s") the input audio (such as a cassette player that is in recording mode), turning on the Input monitor switch will cause the sound to loop between the UA-20 and the other device, causing oscillation and producing an unexpectedly high volume. Be aware that such connections may cause the system to malfunction, or your speakers to be damaged.

Recording a MIDI device

The MIDI messages from a MIDI keyboard connected to the MIDI IN connector can be sent via the UA-20 to sequencer software on your computer.

The MIDI messages from the sequencer software on your computer can be sent for playback to a sound module connected to MIDI OUT.

Digitally recording the output of the UA-20 on an MD

Make connections as shown in the diagram.

• The UA-20 does not support audio formats of professional digital devices.

On the UA-20, the input from the input jacks cannot be output directly to the Digital output connector. The Digital output connector will always output only the audio signal from the computer.

Adjusting the audio latency

When using the UA-20 in Advanced mode, you can change the driver settings to adjust the latency of the audio. To adjust the latency, change the Buffer Size in the driver settings dialog box.

• Latency is the time delay from when an application plays back audio data until the sound is actually heard from an audio device such as the UA-20.

1

As described in "Opening the special driver settings dialog box (p. 65)", open the "Driver Settings" dialog box.

2

Adjust the driver buffer size.

The following setting will produce the shortest latency.
