In the Preferences under Analysis, I set Track Analysis Mode to Normal because the majority of new music is very clean. This will perform Normal analysis when tracks are imported into your collection. If a track is older and needs to be analyzed again, I do a manual dynamic analysis. In Export mode, load a track you wish to analyze into the player. On the right side of the player next the Q (quantize) button, you will see box with 3 lines. This is the Show Menu Items menu and when you click on it, you will see Analyze Track (Dynamic). The analysis will not show you a status, just wait about 20-30 seconds for the analysis to complete. I usually delete all the memory cues before dynamic analysis as it will repopulate the memory cue based on the new analysis. Then I check the beat alignment and add back any cues needed.
Hope that answers your question.
