Dealing With Latency Issues
To avoid these potential pitfalls, try to complete any audio and audio instrument
recording before inserting latency-inducing plug-ins. If you find it necessary to record
an audio instrument or audio track after setting up a latency-inducing signal routing,
the following procedure will help you to get around any possible problems.
To record after setting up a latency-inducing signal routing:
1 Switch the plug-in delay compensation setting from “All” to “Audio tracks and
instruments” in the Logic > Preferences > General > Audio pane.
Note: You can use the Toggle Plug-In Delay Compensation: All/Tracks and Instruments
key command to quickly switch the delay compensation setting between “All” and
“Audio tracks and instruments”.
The “Audio tracks and Instruments” plug-in delay compensation method shifts tracks
that contain latency-inducing plug-ins forward in time—so any audio and audio
instrument tracks that contain latency-inducing plug-ins will be in sync with non-
delayed tracks. There is only one exception: Live tracks can not be shifted forward in
time.
The next step is to eliminate any latency induced by plug-ins in your recording track.
2 Bypass any latency-inducing plug-ins on the recording track by Option-clicking on the
respective Insert slot(s).
In the “Audio tracks and Instruments” plug-in delay compensation mode, bypassing
plug-ins eliminates the latency that they create. Latency induced by plug-ins in audio
and Audio Instrument tracks is compensated for.
The last thing to do is to get around the latency introduced by plug-ins on busses,
auxes and outputs.
3 Bypass any latency-inducing plug-ins on busses, auxes and outputs to eliminate any
latency.
At this point, all audio streams will be synchronized, allowing you to proceed with your
recording.
When you’ve finished recording, re-enable all latency-inducing plug-ins, and switch the
delay compensation setting to “All”.
Note: In the All mode, bypassing plug-ins on busses, auxes and outputs will not
eliminate the latency that they create. You must remove these plug-ins entirely from
the Insert slots to eliminate latency.
