Working With Plug-in Delay Compensation
Logic Pro includes plug-in delay compensation for instruments, tracks, busses, auxes,
outputs and ReWire Objects. A pop-up menu in the Logic > Preferences > Audio >
General pane allows you to activate plug-in delay compensation for either:
 Audio tracks and instruments
 All (Audio Track, Instrument, Bus, Aux, ReWire and Output Objects)
About Plug-in Delay Compensation
Some effect plug-ins introduce latency: this means that it takes the effect a short time
to process the audio fed into it—as a result, the plug-in output will be slightly delayed.
This happens with all dynamic effects that feature lookahead parameters, for example.
Logic provides plug-in delay compensation for all channels: If activated, Logic
compensates for latency introduced by plug-ins, ensuring that audio routed through
such plug-ins is synchronized with all other audio.
Logic achieves this by calculating the amount of latency caused by plug-ins and
delaying audio streams by an appropriate amount—or by shifting instrument and
audio tracks forward in time. The compensation method depends on the type of
channel in which the latency-inducing plug-in is inserted.
 If latency-inducing plug-ins are inserted in bus, aux, ReWire and output channels,
Logic delays all other audio streams by an appropriate amount.
 If latency-inducing plug-ins are inserted in audio and audio instrument channels,
Logic automatically shifts these tracks forward in time. The advantage of this method
is that other channels (that do not contain latency-inducing plug-ins) do not need to
be delayed.
