Logic Pro/Express 7.1: User-created loop doesn‘t sound like the original region

If you create a loop from a region in an Audio Instrument track that uses sends to bus effects, and then drag the saved loop to another Audio Instrument track, the new loop will sound different from the original source region. This happens because the effects sends in the original track are not saved with the loop.

Logic Pro and Logic Express do not automatically assign effects to busses because doing so would potentially interfere with bus configurations that you've already set up in your song. However, effects that are inserted directly on the Audio Instrument channel will be automatically recalled when the loop is dragged to the Arrange window from the Loop Browser.

You can do one of the following workarounds to ensure that loops you create from Audio Instrument track regions will sound the same as the original regions:

• Drag your Audio Instrument loop (whose original region used bus sends) to an Audio track instead of to an Audio Instrument track. When you create an Audio Instrument loop, the audio file that is rendered, including its bus processing. This will sound the same as the original.
• When creating a loop from an Audio Instrument track region, insert all effects needed to reproduce the desired sound directly on the instrument's channel strip. This will allow a faithful recreation of all sound elements when you subsequently add the loop to an Audio Instrument track.
• When using Audio Instrument Apple Loops, manually set up the sends and bus effects needed to reproduce the sound of the original region.
