When editing, you'll be cutting 312 samples ahead of where you think you are, and you'll be unneccessarily delaying any audio that was accurately placed rather than recorded. A Sample Delay can be inserted on each of the Audio Input Objects, so the delay gets recorded and the audio is placed correctly in the Arrange. This is only possible in Logic 5, not Logic 4. By inserting the Sample Delays on Input Objects, you can accurately compensate for different A/D converters, digital loopbacks, etc, which will all exhibit differing record offsets; though you'll be doing so at the expense of adding additional latency when software-monitoring. It may be desirable to adjust your ASIO buffer size so the ASIO driver "IN" adjustment is as close to being accurate as you can get, before you start adding Sample Delays to inputs.
