Adjusting The Audio Latency - Roland EDIROL UA-1EX Bedienungsanleitung

Adjusting the Audio Latency

When using the UA-1EX 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 sequencer software plays back audio data until the sound is
actually heard from an audio device such as the UA-1EX.
1. As described in"Opening the dedicated driver settings dialog box" (p. 44), open the "Edirol
UA-1EX Driver Settings" dialog box (or in Mac OS 9, "ASIO Control Panel").
2. Adjust the buffer size.
The following settings will produce the shortest latency.
Windows users
Set "Audio Buffer Size" to the far left (Min).
Mac OS X users
Set "Audio Buffer Size" to the far left (Min).
Mac OS 9 users
Set "Buffer Size" to the far left (Min).
3. Click [OK] (or in Mac OS X, [Apply]) to close the dialog box.
4. Restart the sequencer software that is using the UA-1EX.
* If you are using a sequencer software that has a function for testing audio devices, get it to perform its tests.
5. Play back audio data on your sequencer software.
If interruptions occur in the sound, repeat this procedure, and gradually increase the buffer size
in step 2 until interruptions no longer occur.
* Depending on the sequencer software you are using, there may be a buffer size or latency adjustment
function among the audio settings of the sequencer software as well. For details, refer to the operation
manual for your sequencer software.
