Creating Overview - Again

This is happening on Snow Leopard with Logic 9.01 and is reproducible every time. I record a bunch of tracks in a session, save and next time I open the project, it goes through the "creating overview" process drawing all the waveforms recorded in the last session, can take a few minutes if a lot of tracks were recorded. If I then save it again, and open again without recording anything new, it opens without "creating overview", anything new that gets recorded will get the "creating overview" treatment next time I open the project. Is anyone else experiencing this? and if so, is there a solution? It's driving me nuts, and if I were ever brave/insane enough to use Logic 9 in a commercial enviroment, it would be very embarrassing for clients to have to sit through that.

I believe this problem is related to the "blast of white noise" problem that is seriously affecting many users hearing, and the audio losing sync problem. I also believe it is due to the fact that Core audio is hopelessly broken in Logic 9. I say hoplessly because surely if a problem as serious as this was fixable it would be fixed, either that or they just don't care anymore.

Hello!

I had the same problem with creating overview again and again and it was a 40 track 2 hours live session so You can imagine how annoying it was. But suddenly today I opened the session and it didn't happen! I don't know why but the problem turned out not to happen anymore with this session. I opened the session again and it was the same - no overviews calculating. I don't know how it is possible and unfortunately it's my only session recorded in logic 9 so I can't test whether the problem disappeared particulary in this session or it's somehow globally self-fixed hehe 😉

But unfortunately it's not my only problem!
A cultural institution in my town called me for an advise on what recording gear they should buy. As they have a Soundcraft Vi4 console in their concert hall I advised them to buy a RME MadiFace with a 17" MacBook Pro (as it only has the expresscard) and Logic Pro. It was the best price to channel number solution and the Vi4 has a Madi in/out so it was and obvious choice. Ok so the gear came to us at December 18th and the gig was December 20th so I didn't have so much time to test it - in fact I had only time to install Logic and i didn't test the recording :P I thought that it's a great computer with a great RME interface connected to great console so everything's gonna be allright 😉 Of course it wasn't. RME drivers shown that there was a perfect synchronization between the console and the interface. But Logic had a problem...The console works at 48kHz sample rate (for the compatibility with television I suppose) and it can't be changed to 44.1kHz. But everyone would say it's not a problem - You record it 48 and that's it. But unfortunately Logic had a problem with that from the very beginning. Before I started the recording I changed all the possible sample rates to 48kHz. I changed the sample rate in Logic, I changed all the sample rates in Audio/MIDI configuration to 48 - just to be sure that I'm good in every point. I press the record button, and a few seconds later I get an error - Logic claimed a synchronization error which was something like "sample rate conflict - sample rate 44100 detected instead of 48000" and I just went - ***? 😐 I restarted the computer, checked once again that everywhere I have the 48kHz sample rate. I turn on Logic, press record and now it's good. "Ok so I'm good". Nothing more wrong :P I stopped the test recording, waited for the concert, and 5 minutes before it I started the actual recording. Yes You're right once again the error happened. I had to once again restart all the gear and start the recording and it was good. "Ok so I'm good now" - nothing more wrong heheh 😀 after 1 hour of recording Logic once again lost the synchronization and I had to restart all the system to start recording again and I lost one song because of that. And what can I think about it? I advise an quite expensive system to buy and I assured that it will work fine and what? It' just worth sh** because of Logic 9. I'm sure that the synchronization between the console and MadiFace was perfect I checked it a thousand times, everything goes bad after pressing record the second time in Logic. You open Logic start the recording and You're good, You stop the recording after 5 seconds and start it again immediately and it shows the synchronization error. What can I do? I suppose nothing till an update goes out...Hopefully I didn't agree on money for this first recording because I wanted to start a longterm cooperation on recording concerts for this institution - i didn't agree on money and the recording is worth sh** so I'm clean - but what if I agreed on money? I think the longterm cooperation plan wouldn't work out 😉 But now I have to find the solution to make some money on this gear and in January there are some concerts to do that but the gear doesn't work so what can I do?

9.1 seems to have fixed this, which proves it was indeed a bug with Logic 9. Well done apple for fixing it, but shame on apple for releasing the program in this state in the first place. I can't seem to find it mentioned as fixed or even acknowledged as a bug, guess it must be too embarrassing for them to admit a show stopping bug this obvious got through.

I'm still encountering this "overview creation" problem faithfully with Logic Pro 9.1.0 (in both 64-bit and also in 32-bit mode) on my MacBook Pro 2,1 running OS X 10.6.2. Every time I create a new project and try to add two 192 kHz stereo WAV files (of the same length/size but recorded using a different application) as audio tracks, the overview seems to be created successfully for each of the two stereo files (with the "Fast" creation option checked). I definitely see the overview appearing in both tracks on the screen. I then save and close the project. The next time I open the project, one of the two stereo tracks invariably needs to have its overview created again. I also notice that the size of the WAV file in the media bin is a fraction of a megabyte smaller for the file that "lost" the overview. However, after the overview is created again for the file, and after saving the Logic project again, the overview seems to "stick" (and the two stereo files are once again the same size).

After further testing, the bug seems to be correlated with overview creation/saving of multiple audio files with "longer" file names. The pairs of audio files I've been adding to new Logic Pro projects have fairly long file names (about 41 characters in length) and the first 40 characters of the file names are typically equivalent with the last (41st) character being the only difference (e.g., a suffix of 1 vs. 2 at the end).

However, since one of the new features of the 9.1.0 release allows Logic to use long file names for the first time, I thought I'd check if the same behavior occurred for shorter file names (e.g., 8 characters long with the 8th character being the first different character). It does NOT occur for shorter file names. The overviews are created one time only and they "stick" the next time the project is opened.

Summary: It appears that whatever code was written to allow Logic Pro 9.1.0 to use long file names has a bug in it somewhere that is not properly differentiating long file names (that are equivalent for the first 40 characters or so) when it saves overviews created for multiple files at the same time.
