MixMeister BPM Analyzer is a free program you can use to determine the exact BPM (beats per minute) of any song. The tags in most digital music files provide no BPM information at all, and others contain estimates which are often inaccurate. Whether you´re choosing songs to mix together, building a playlist for a specific mood, or comparing different versions of a song, BPM Analyzer makes finding the correct BPM easy. This is a simple program, but the BPM measurement engine is adapted from MixMeister Technology´s award-winning line of pro DJ software, and it generates the most accurate BPM counts available anywhere. MixMeister BPM Analyzer supports dragging and dropping files from Windows Explorer, and allows you to sort your music list by Title, Artist, or BPM. You can update ID3 tags in your music files with exact BPM information, print BPM reports for your entire music collection, or even export BPM counts for use in other programs like Excel or music databases. This is a fully-functional version. You can use and distribute this software completely free of charge for non-commercial purposes.

I am also having some problems with MixMeister & iTunes.
Things to note:
1) I have all my Mp3's stored on an external hard drive.
2) All I use iTunes for is ripping songs from CD and editing iD3 tags such as Genre, BPM, Title & Artist. As far as i'm aware this information is stored with the Mp3 not just the iTunes database.
2) I don't have the 'read iTunes library' check box ticked in the SSL setup page because I'm not importing playlists etc.. from iTunes yet.
This is the procedure I follow that is causing me problems:
1) Rip CD to external hard drive using the iTunes Lame encoder.
2) Run MixMeister on the Ripped Mp3's to find BPM of all tracks. I leave iTunes running in the background.
3) Select all the Ripped Mp3's in the iTunes library, right click and select 'Info' then click o.k button. MixMeister is still running in the background displaying all the BPM's of the selected Mp3's.
For some reason when I follow the above procedure MixMeister finds all the BPM without problem but doesn't transfer them to the iTunes library.
If I then repeat steps 2) & 3) it will then transfer the BPM o.k. but I don't know why I have to repeat this process twice before it will work.
Having to do this twice is a real pain because running MixMeister on a large quantity of MP3's takes ages.
Another problem I had was when I ran MixMeister on some Mp3's I already had been using on SSL. This is the process I followed and the results I had:
1) Run MixMeister on the Ripped Mp3's to find BPM of all tracks.
2) Select Ripped Mp3's in the iTunes library, right click and select 'Info' then click o.k button.
3) Repeat steps 1) & 2) or BPM's don't show in iTunes.
4) Open SSL and rescan iD3 tags from the setup page.
When I had completed step 4) of the above procedure approximately 50% of my SSL library had ? in the status icon box.
The only way I could correct this was by deleting my entire library from SSL and importing all the Mp3's again.
A result of this was that I lost all my crates.
Can someone please tell me where I am going wrong In my procedure for transferring BPM's from MixMeister to iTunes and then to SSL?
I have searched other threads and posts for the correct procedure however none of them appear to work for me.
Thank you
