Logic Pro 7.1 Addendum

Q Q Q

When you select All in the Plug-in Delay Compensation preference, the com-

pensation technique for regions of the Arrange window remains the same,

but now Logic automatically delays, by the largest amount of delay of any

single stream, all other audio streams running parallel to Bus, Aux, Output,

and Rewire objects so that all audio streams remain in perfect sync. Full

plug-in delay compensation works completely seamlessly—simply activate it

when you are mixing, and you can use any plug-in, on any Audio or Audio

Instrument track, Bus, Aux, Output, or ReWire object, and all your audio

will remain in perfect, sample-accurate sync, regardless of the delay caused

by various plug-ins. If you insert a delay-causing plug-in on the fly during

playback, Logic may not adjust to the new plug-in delay quickly enough. If

that happens, stop playback, then begin playback again. Everything will be

in sync.

Limitations to Plug-in Delay Compensation

There are a few limitations to plug-in delay compensation that you need to

understand. First, as I explain in Logic Pro 7 Power!, plug-in delay compensa-

tion is a playback only feature. If an audio track is on hard disk, or if the

audio stream to the bus is coming from another audio channel, Logic can

apply delay before the audio stream plays back. But if the audio is stream-

ing live, there is no way for Logic to delay it to match the delay of the other

audio channels. This means that if you try to record through plug-ins that

cause delay, your track will not be compensated, even if plug-in delay com-

pensation is on. However, if you don’t wish to record through delay causing

plug-ins, you can still record audio in “All” plug-in delay compensation

mode; just make sure software monitoring is off, so you are not monitoring

through Logic. Logic will automatically line up your audio after you record it.

Also, while in

plug-in delay compensation mode, Logic Pro 7.1 advances

all the audio streams by the number of samples necessary for all audio to be

in sync, the graphics are not advanced. So depending how much compensa-

tion Logic is doing internally, you may find that channel strip and plug-in

meters, and possibly even QuickTime Video being played back with your

Logic song, might appear out of sync with the audio. These graphic issues

have no effect on your audio at all, but can be a bit disconcerting if you’re

not expecting it. Hopefully, this will be addressed in a future update to Logic;

until then, just be aware that if you notice that some graphic elements aren’t
