Just added a whole bunch of mp3's to the catalog, left MM4 on overnight calculating the bpm's and plots, or so I thought. MM4 reported it had finished calculating the bmp's and plots but whenever I add a track to the playlist it has to create the plot. The track then seems to have the plot information saved if I use it again, I'm sure in MM3 putting tracking in the catalog did all this?
Do I have to drag all 3000 mp3's into a playlist to force the plot creation!?

It sounds like the software discarded some of the plots in order to save space.

By default, MixMeister uses only 100MB of disk space on plots, which corresponds to a few hundred songs. However, you can change this setting.

Open the Tools, Options dialog and look in the Plot Files tab. To ensure that MixMeister builds the plots once and only once, click on the unlimited box. You may want to reimport your catalog afterwards to force all the plots to be rebuilt.

Let us know if this does not help.
