Help needed to save a session created on Mixbus

The Event Viewer is a Windows program for seeing Windows system log entries.
But if you haven’t worked with it before it’s a bit tricky to use and I’m not particularly well versed in it either.

If those exact folders exist on F: and contain the appropriate files it’s really weird if MB can’t find them.
The only thing I could think of is if the file system permissions somehow got screwed up, but then you shouldn’t be able to copy them in the first place either.
At least not if you’re copying them as the same user your running MB as.
If the file permissions are off and you copy them as the Windows Administrator then your ordinary user could have a hard time reading them afterwards.

OK maybe just upload the .ardour session file then. Perhaps that can shed some light already.

Give this time and a bit of patience.
I have hope you’ll be able to fix this issue. :slight_smile:
:clock10:

:point_up_2: Robin here is one of the two main developers behind Ardour, so you’re in the best possible hands. So I suggest passing him some (or all) of your data!

(@x42 This does make me wonder… Given his project size, is there some kind of max. project size limit enforced somewhere? -Maybe by Windows? Hmm…)

@darock When did this start happening? What was the last thing you were doing with this project before your difficulties appeared? Also, how does this particular song and its project folder compare to the other songs in the album? Is this the biggest (in terms of GB) project of the group?

Thanks a lot for your help guys, here’s the ardour session file and xml, bak and history bak :

@GhostsonAcid : it started some days ago, as I was recording a reamping of 5 tracks of guitars. It stopped recording after approx 1 bar, did thoses strange diagonal waveforms. I closed MB, then re opened the session and I could make another recording, then it started to stop once again. I noticed that I can make just one recording, then after a stop, it start doing thoses strange things if I try to record once again and I can’t save the session anymore. When I close the session, MB seems to not find the other sessions in the Open start window anymore, I need to close MB and start it once again.

The other songs of the album are on the same disc and folder, and this song is, by far, the biggest of the project.

The “diagonal waveforms” means that a file cannot be read from disk … it is either missing, permissions are wrong, or corrupted.

@paul :point_up_2: That’s not a clue to something else going on? :thinking:

No, it really isn’t.

or the timestamp is wrong. In which case Menu > Session > Cleanup > Rebuild Peakfiles
can help.

In that the session would still play correctly though, and it’d just the waveform display that’s not working.

So here I can load the session (on Linux). Save works but takes 5-6 seconds…
The audio files are missing, but there is nothing obviously wrong at first glance.

PS. My main machine is to slow to process it 100% DSP load.

Can you create or copy new files in the folders where the wav files are?
Just to make sure that you have the proper permissions to the folders.

Is it possible that darock’s computer has simply run out of RAM?

Remember also that on Windows, sessions have a limit of 2048 simultaneously open files

Something like this sounds plausible.

@darock - I’m not sure if this’ll help but it might be worth a try…

Within Mixbus, open Window->Preferences->Show->General and under Session Management, check to see if Make periodic backups of the session file is enabled. If it is, look to see if Mixbus has already been making periodic backups. If it isn’t enabled, try enabling it and see if Mixbus itself is then able to save occasional backups of your session.

Good luck!

Hi guys,

Really sorry for the delay of my answer, but as I live in France, there’s this jet lag. Moreover, as I am a new user, there are some limitations and I’ve reach the maximum replies per day, so I couldn’t reply until now.

To Robin : the session still plays correctly but it dosen’t save anymore, so it stays in that state and the song is not finished recording, nor mixed.

My goal now would be to Consolidate all the audio files from start and import it on a new session, as Nathan from Harrison told me that the problem is due to the fact that I initially created the session on MB 8, then worked on it on MB 10 and now on MB 11. But when I consolidate tracks, it works on 1 track but not on all the others.

To peder : I tried to copy a file on the folder and it worked.

@John_E Interessting idea. My PC has 32 GB of Ram. About the files limit, I didn’t know about that. But that’s a really great idea too, because this session has 2082 audio files.

The periodic backups is enable. It seems to work for that point.

The question is, can I make some things to make the session reliable again. I thing that I’m thinking about : making multiple copies of the session, and at each copy, deleting different groups of tracks, then trying to consolidate each remaining groups of track, to finally assemble them in a new session, which would same me the editing.

@x42 Thanks a lot to have opened the session. Could you just deactivate some track to lower the CPU load and try to record some tracks to see if it works.

Thanks a lot guys

Any chance you have access to a Mac or Linux system to test the session on? Those should not have the same file limit.

This does raise an obvious question I guess - i.e. how did @darock manage to create sessions with so many audio clips? In his original post he mentions creating one session with over 4,000 clips which is a pretty interesting scenario… AFAIK Mixbus (on Windows) shouldn’t even be able to record so many audio clips. Or were they imported from some other system somehow?

Hi folks,

Sorry once again for my very late answer but I did some extensive tests and stuff yesterday.

@John_E When I did a Save As, MB told me there was 4400 audio clips to copy. But when I checked on the Audoclip folder, there was 2082 wav files. I ignore why there’s this difference.

So as I said, I did loads of tests and stuffs. But as @John_E pointed out, I tried to do a massive clean up : all the drives, all unused plugins, all unused tracks and audio clips in the session. I did the clean up on MB too, and it allowed me to consolidate all the tracks. Then, after that I did another clean up, so my project turned from 2082 audio files to a few dozens.

And guess what : it worked. And if, in the future, I have another issue with the session, the consolidate audio files allows me to import the edited audio on another new session.

I can’t thanks you so much guys for the help. You rules !!!
