on the Use Audio Units option activates Audio Units Plug-ins so that they appear in Live's
Plug-In Device Browser.
Note that you can always turn this option off later if you decide not to use Audio Units.
Activating Audio Units
Plug-Ins.
Audio Units Plug-ins sometimes have a feature that allows choosing between different
modes for the device. You might be able to choose, for example, between different levels
of quality in the rendering of a reverb. Choosers for these device modes can only be
accessed through the original plug-in panel, which is opened using the Plug-In Edit button.
Opening an Audio Units
Plug-In Window.
Audio Units have presets that function just like those for the Live effects. However, some
AU presets cannot be dragged to different locations in the Browser, as they are read-only.
Audio Units presets have an .aupreset extension and are stored in the following directory
according to their manufacturer's name:
[Home]/Library/Audio/Presets/[Manufacturer Name]/[Plug-in Name]
16.5 Device Delay Compensation
Live automatically compensates for delays caused by Live and plug-in instruments and
effects, including those on the return tracks. These delays can arise from the time taken by
devices to process an input signal and output a result. The compensation algorithm keeps
all of Live's tracks in sync, regardless of what their devices are doing, while minimizing delay
between the player's actions and the audible result.
