Enable Artist Separation in Random
Very basic artist separation for random mode playlists, in minutes.
Enable Category reject in random
If you randomly automate from the entire DPS library, you may need to specify which categories never to play, eg Christmas songs, instrumentals, etc. If you have categorised the cuts in Edit Player, you can now optionally choose the random playout to reject these categories. Multiple categories must be separated by a comma.
Play only These categories in random
The exact opposite of the above. Again, use commas to separate categories. It is preferbale to specify the categories to play, rather than the ones to reject, as you are less likely to get undesirable audio! (You have to be explicit!)
