Search
The current volume is searched for filenames. If the search is unsuccessful, Logic asks
you if you want to search other volumes for these files. This enables you to assemble
songs, even if you have copied or moved the relevant files onto other media.
Skip
(Don’t search for this file). Use this function if you know that this audio file no longer
exists, or was renamed. This button changes to “Skip All” if further audio files aren’t
found.
Skip All (for Several Files)
(Don’t search for any more files). Use this function if you know that all audio files in this
song no longer exist, or have been renamed.
Manually
You can manually define where to search for the file. A file selector, containing the
names of the audio files being searched for, appears onscreen.
If more than one file with a matching name is found, you can select the correct file in a
dialog box.

Setting the Sample Rate
Logic performs a real time, native sample rate conversion. Any sample rate available in
Logic (via Audio > Sample Rate) can be used for the conversion—even if your audio
hardware does not support the selected sample rate.
The native software sample rate conversion facility matches the sample rate of any
audio hardware, thereby allowing the playback of projects on virtually any audio
system—even if the hardware is—in sample rate terms—not compatible. Nothing is
lost in the process. Any internal processing and bouncing is always performed at the
original sample rate, and at the highest quality, even in cases where the hardware does
not support a particular sample rate. This facility allows you to work on projects
originally created on high-end audio systems, with smaller setups.
Example:
A song was created with an audio hardware/setup at 96 kHz. Moving this project to a
laptop, or setup that does not support the original project’s sample rate, will commonly
result in the wrong playback speed. The native realtime sample rate conversion facility
will counteract this effect, allowing correct playback of the project on the laptop, at any
sample rate.
High sample rates not only eat drive space, but also result in more CPU load, because
everything has to be handled in half the time.
