Hello trixmoto, I have been playing with this BPM malarky over the past couple of days.
Firstly I have had to run that MixMeister thingy across all my library- and that is taking forever; I have started leaving it running over night now. Still not finished.
Interesting early results are that my lowest readings (65-75) are coming from the 1972 Bowie LP: The Rise and Fall of Ziggy Stardust and the Spiders From Mars. Whereas it is not reporting anything over 200BPM. (Why?) And I can see no real pattern of Artist nor Genres at this level.
And I think I am getting the hang of this Tolerance business now. Following your suggestion I have set it to just 3 and I can now see future tracks at the same BPM as the track playing.
select a track to play the Auto-DJ then picks tracks at the same BPM as the new track. Clever stuff.
I am no HipHop-DJ but I do make what were always called "mix tapes" and I think this will help in programming the play order in future. Thanks for your help.
