Track Separation MAJOR Problem!

hi

I think the problem is with export import database. Import the database before using Rekordbox and check it. Set database as default. Open RB as administrator.

Thanks for you reply.  

I am not sure I understand what you mean by "import database b4 using RB".

I didn't import, I restored.  

When I installed RB on Mac after clean install of  MacOS, I restored the database with the backup I created before  OS  installation as soon as I opened RB for the first time.  I didn't need to import, as the restoration took care of  identifying where my music is, the track analysis, cue points, RB settings..etc.  I put back my  music folders in the exact location that they where in b4 the OS installation, so everything worked out just fine for about 4 weeks when that problem happened just all of a sudden.

The same on PC, I installed RB for the first time, restored database, but I didn't put the music folders on the internal drive.  I kept  the music on an external HD, and adjusted the RB settings to look for missing files on that external HD.  Again, everything worked perfectly fine until I shut down the PC.  But when I started  the PC and opened RB again, I was faced with the exact same problem that happened on Mac, only thing that on Mac it took about 4 weeks to happen, where as on PC only just one reboot!

I also don't know how to set the database as Default.  There is an option in RB to set the location of the Master database.  So can you please clarify how to set it as default?

I will try to open RB as Admin on the PC, and will check how to do the same on Mac as as I am not really sure I know if tights even possible on Mac.  

What I stil don't get is why without doing anything of what you  mentioned ,  everything worked v. well on PC until I rebooted, and was also working just fine on Mac for almost a month.

Anyways will wait for your clarification of how to do these steps anyways, hope they will solve the issue.  

Thanks alot.

I had a similar problem. Copy some tracks to your internal drive, create a master database on your computer's hard drive. use rekordbox then reboot system. do not use an external hard drive to test this.

On Mac everything is on the internal drive,,yet that issue occurred 

You did a system update ? what macOS ?

Yes I did.   please read the initial post.  

I installed MacOS Monetary when RB 6.7 came out to give the Mac a speed boost which it.  And after RB was working fine for weeks befor3e the issue started happening.

Ok there is an update...an interesting one!

On PC, I went to settings, and changed the location of the master database to the external drive. Shut down RB. Disconnected the external drive, Then started RB. I got an error message saying that the Master database can't be found, and asked if I want to use the one on local drive, which I said OK to.  Then it asked if I want to restore the Master DB from backup, and I said no as I needed a new fresh DB.   This made RB start clean with nothing in the  collection.  I then imported few  tracks.  And this is what I found out.  The TS analysis still does take a decent amount of time, BUT, its happening in a continuous manner from the beginning to the end of the track, the blue bar is going one direction from start till end of  the track. But  since its a lot faster than the playback speed, you can immediately start isolation as soon as the track loads. I am sure that this is what was happening on the Mac all this weeks but I didn't quite notice it.  

I then switched the Master DB to the external drive.  I got my whole collection back with cue points, playlists..everything.  Here is the interesting part, and it seems to be the cause of the problem.  Track separation doesn't progress in the same manner (ie from begining  to end).  Rather, its happening at random parts of the track! You can see the blue bar  progressing at different part of the track randomly.  And thats why the beginning of the track doesn't get analyzed first, So when you try to isolate, it doesn't work cause the beginning of the track is not yet analyzed, and could be analyzed after a significant part towards the middle or the end has been analyzed!  Don't  know if thats a bug or why such behavior is happening, but thats the case.

Then It gets more interesting!

I go back to settings, change the internal HD as the Master DB.  I get all my collection back, with cues, playlists, etc. AND  a normal progress of TS analysis! Great!

II wanted to see if it will still work properly if  restarted  RB...but the collection went back to the few tracks I had recently imported after I reset the database! Even thou right before I closed RB, everything was there!  So I went to settings, moved the Master DB to external drive, the collection came back with cues, but with the random progress of the TS analysis again !!  

Ok this is the most interesting part..I change the MDB to internal HD, the collection came back, but this time without Cues and with random progress of TS analysis!!!  What, I just did that and got the cues and the normal progression, but not this time!!

Thats such an erratic  and inconsistent behavior and outcome for the same exact steps and procedure!!

There seems to definitely  be something wrong there!!

Ok as a last trial, I restarted RB, it opened with only the few imported tracks as usual . At this time I restored library  from backup. But this time I copied a music folder to the internal HD, and told RB to only look for missing files in that folder. Unfortunately , I got the random TS analysis progress again , leading to the exact same problem!!!

I have no clue what's happening, but I think that this MUST be a bug.  And there is no way I would import my tracks again from scratch.  I have over 3000 tracks, all with cue points, loops, not to mention the playlists, that there is NO WAY on earth I can do again in case a reimported to a new database!!

Can please someone from the modulators shed some light or offer some help on this? Am I doing something wrong ? Is there anything I can do to keep my database with cues and playlists , and still get a normal TS analysis progress like I had on Mac for 4 weeks, and on PC for 15 mins before I restarted it??

Looking for an answer.  Thanks

Can you please file an inquiry ticket here and our support team will gather some additional information to assist you in resolving this issue?

Ok Thanks , I just did. I also attached a video to show how the analysis progress behave.  Couple of more points:

On Mac, I just added a new track to the collection, and the track serration analysis behaved NORMAL as it should.   So the random analysis behavior seems to only happen on tracks that where part of the backup/restore operation.

Another thing, I just remembered that last week when RB was still acting normaly on my Mac,  I had a gig, but didn't want to play with that minor glitch in sound that would sometimes occur when loading a track (As mentioned in my initial post). So I borrowed a friends laptop that has more RAM.  I out all my music folders on the exteranl hard drive, but didn't want to copy it to his computer.  So I MOVED the database from my RB to the external drive , and thats when all the problems started happening after.

So apparently moving the Master database to an external drive cause such erratic behavior of TS analysis, even if you move the MDB back to the local HD.

For me Rekordbox analyzes from cue points first. which seems normal because you can press it at any time. when a song has no cue points, it analyzes from start to finish.

How to move a rekordbox database:

Well that kinda of make sense that it does the CUE points first..but the thing is..I haver a play list that I am trying to record..I played it several times and never had any problem with separation.  I sometimes start a song with a loop towards the end of it, before I go back to  play it from a point towards the beginning..and I didn't feel that the serration wasn't working at all..it was just perfect..but now I can't do the same , with the same tracks, and cue points, there is a big lag b4 the separated parts are ready.  To be honest, I never paid attention to the progress bar before , so I can't really tell if it was happening at a faster rate or with a different pattern.  All I know is that I can't now play the same set in the same way that  I already did several times.  Could it be possible that the the analysis just slowed down all of a sudden for whatever reason? Thats weird.  On Mac I have been using the TS for weeks now..and never felt a lag wheever I needed to play any part of the song..this only started happening when I moved the DB to the external HD then back ti the Internal..Everything  else is unchanged.  So what could the reason for such a slow down in analysis, if thats the case.

Hello friends!
I am also having the exact same problems.
I even formatted my Macbook thinking it might be because I haven't formatted it in years and it didn't solve the problem.
The analysis is so slow that the music ends and the analysis doesn't.

Now, just a suggestion, and I apologize in advance if I'm wrong: the RB could save the analysis once done.
Every time it loads the song it does the analysis again.
