Tick-based audio is fixed to a Bar|Beat location, and moves relative to the sample Timeline when tempo and meter changes occur. However, MIDI events and tick-based audio respond differently to tempo changes with respect to duration. MIDI note events change length when tempo or meter is adjusted, while audio clips do not (unless Elastic Audio is enabled). When Elastic Audio is not enabled on an audio track, meter and tempo changes affect only the start point (or sync point) for each audio clip in a tick-based track. If Elastic Audio is enabled on an audio track, tempo changes apply Elastic Audio processing, which changes the duration of the audio clip.
