Chapter 36 Working With Plug-in Latencies 869
For these same reasons, you may encounter increased latency if playing software
instrument tracks live, when plug-in delay compensation is set to All. This issue can be
mitigated to some extent by using the Low Latency mode (see “Working With the Low
Latency Mode” on page 866).
Dealing With Latency Issues
To avoid these potential pitfalls, you should try to complete any audio and software
instrument recording before inserting latency-inducing plug-ins. If you need to record
a software 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 and Software
Instrument Tracks in the Logic Express > Preferences > Audio > General tab.
You can also use the Toggle Plug-in Delay Compensation: All/Audio and Instrument
Tracks key command to quickly switch compensation between All or only Audio and
Software Instrument Tracks.
The Audio and Software Instrument Tracks plug-in delay compensation method shifts
tracks that contain latency-inducing plug-ins forward in time—so any audio and
instrument tracks that contain such plug-ins will be synchronized 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 introduced 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 slots.
In the Audio and Software Instrument Tracks plug-in delay compensation mode,
bypassing plug-ins eliminates the latency that they create. Latency caused by plug-ins
in audio and software instrument tracks is compensated for.
The last thing to do is to get around the latency introduced by plug-ins on aux and
output channels.
3 Bypass any latency-inducing plug-ins on auxes and outputs.
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 actually remove these plug-ins from
the Insert slots to eliminate latency.
