Safe Mode. Changes How the StudioLive Driver’s Buffer Size is Set.
• Low Latency. Input and output buffers are both identical to the Buffer Size setting.
• Normal Mode. Slightly increases the output buffer for typical operation.
• Safe Mode 1-2. Increases the output-buffer size for added stability.
Block Size (Windows Only). Changes the StudioLive Buffer Size.
You can set the buffer size from 64 to 4,096 samples. The buffer size determines
the roundtrip time it takes audio data to be converted from analog to digital and
back to analog. As a general rule, the higher the buffer size, the better the system
performance, but the less playable virtual instruments and the like become. In
general, 512 samples (11 to 12 milliseconds) will provide you with a large enough
buffer for optimum system performance, but low enough to be unobtrusive.
You should set your buffer size prior to launching your host application.
On the Mac, the buffer size is set from inside your host application.
Power User Tip: In the event that audio playback from your computer is distorted
or choppy, you may need to adjust your Block Size so that it is high enough for your
computer’s performance capacity. For most modern computers, a Block Size of 32 or
64 samples will perform quite well in most situations. However, if you have loaded
several plug-ins that require a large CPU overhead, your computer’s processor is
older, or you do not have adequate RAM for your use, you may find that a Block Size
of 256 or higher will allow you to add more plug-ins and tracks. Adjusting the Safe
Mode to 1 or 2 will also help get better performance out of slower machines.

4.2 VSL-AI: Browser
When you first launch VSL-AI, notice the browser window along the right side of
the screen. The browser in VSL-AI functions similarly to the browser in Studio One.
From the browser, you can see all of the scenes, Fat Channel presets, FX presets,
and graphic EQ settings that are saved on your StudioLive and on your computer.
You can also create new settings and can back up your entire library from this
window. Simply drag-and-drop a scene or preset to load it on your StudioLive.
VSL-AI allows you to back up your scenes, Fat Channel, effects, and graphic EQ
presets and permanently store them on your computer. Each type of preset can be
added separately. In this way, you can back up only what you want, when you want.
