866 Chapter 36 Working With Plug-in Latencies
Working With the Low Latency Mode
The Low Latency mode allows you to limit the maximum delay time caused by plug-
ins. Plug-ins will be bypassed to ensure that the maximum delay that can occur across
the entire signal flow (of the current track) remains under the chosen value. The Low
Latency mode is extremely useful when you need to play a software instrument (or to
monitor through an audio channel) when plug-ins with high latencies are already in
use—at any point in the signal flow for the selected track/channel.
To set the maximum delay time allowed in Low Latency mode:
1 Choose Logic Express > Preferences > Audio, then click the General tab.
2 Set the Limit slider to the desired value.
To activate Low Latency mode, do one of the following:
m Click the Low Latency Mode button in the Transport bar.
m Switch on the Low Latency Mode checkbox in the General Audio preferences tab.
This limits the latency generated by plug-ins to the value set with the Limit slider. Plug-
ins will be bypassed, ensuring that the maximum delay that can occur across the entire
signal flow (of the current track’s signal path) remains under the Limit slider value.
 Bypassed plug-ins may be on the selected track, any auxes in the signal path, or even
output channels.
 Plug-ins with the highest latencies will be bypassed first.
Note: The sound may change in Low Latency mode. Depending on the plug-ins in use,
the changes can be anything from subtle to dramatic. If plug-ins being used do not
exceed the total latency limit, there will be no audible difference.
