output increases when I create new tracks
Hi
This may sound stupid, but it's doing my head in. My students are tracklaying on an audio post session for their film. They have discovered today that if they add a new audio track to the session, the Protools output as measured on PPMs jumps by about 8dB. If we delete the track the levels stay high, but if we revert the session, everything is ok again. I know I can add a master fader to bring the level back down again, but I really want to know why this is happening. Apparently their session crashed last week, producing a saved version with gobledegook name, but I don't know if that is related. Any ideas gratefully received. Protools v6.4.1 on TDM mix plus system on MAc osX.

Re: output increases when I create new tracks
I used to get all sorts of weird things under mix 6.4.1. Wrong routing, wrong levels etc. Normally deleting the i/o-setup and making a new one cured the problem.
Try deleting all in the output-tab in the I/O-setup and then re-create new pathes. It seemed to me the I/O-setup can become corrupted and all sorts of weird stuff happens. Suddenly the center-path played back in the surrounds etc. Audio playing back 12 dbs louder than indicated etc. frank.

Re: output increases when I create new tracks
Thanks. I'll give that a go.
I'm tied to this version because later ones won't work with my hardware

Re: output increases when I create new tracks
It was actually 12dB higher!
Anyway, thanks again Frank. Your suggestion fixed it.

Re: output increases when I create new tracks
It's me again, with the same problem, more than 3 years later.
We really need to start saving up for some new hardware! I tried following Frank's advice this morning and deleting output paths, but when I got to output path 1/12|88824 the following warning appeared: " The output path "1/12|88824" is currently being used in the session. if you continue, all the assignments to that path (and associated sub paths) will be removed. Volume, mute and pan automation may be deleted on affected tracks". I tried changing all in and output paths in the session to A 3-4, but still got this message. So how do I delete and re-create new output paths safely? Surely if I save a backup of the session and the "last known i/o" file, nothing will get lost? I'm probably being paranoid, but don't want to risk deleting all the student's automation work. Thanks for any help/advice/reassurance! |

Delete it anyway! it won't hurt, you'll just have to re-assign any tracks that are using that path. Chris

Re: output increases when I create new tracks
Cheers Chris.
Of course you were right - that stupid warning message just made me paranoid. Unfortunately, it didn't fix the problem. Maybe last time I did that it worked because the session had been reverted to an earlier state before the problem arose? Looks like I'll have to go with a -12dB master fader |

Re: output increases when I create new tracks
It would be a good lesson to rebuild the session (track by track if necessary) with Import Session Data to find out if there is one problematic track that can be avoided.

Re: output increases when I create new tracks
Thanks Jim.
I thought the -12dB master fader had fixed the problem. However I've got a dubbing mixer in today working on the session and weird stuff is happening again. So I'll give your suggestion a go while they do lunch. |
