Merging in Logic

[nickynicknick]

Hey Guys....anyone know if a file is degraded in any way when it is merged in Logic...is there any Merge preferances...i can't find it if there is...the reason i ask is because it is a digital mixdown and sometimes digital mixdowns can be inaccurate. Thanks.

Haha, you've hit the nail that has been bothering me for 2 weeks on the head.

I had a Logic session last week that I had to 'consolidate' for a ProTools mix.

'Easy' I thought, OMF it.

I get the session into protools and pretty much all files had drifted randomly by 3-10 samples. Of course this took me several painful hours to realise.

'Alright, I'll merge each file one by one' I thought.
I was pretty pissed off when I realised that even that had the same problem, odd phasing and general weirdness.

The only solution I am aware of for fixing this is running a seperate Logic rig into PT via spdif/aes and recording the result realtime.

Completely and utterly, really very stupid and annoying.

Logic is by far my least favourite 'proper' DAW. I like using it on it's own but getting anything other than a stereo mixdown out of it reliably is a complete nightmare.

that's very interesting...although you should try export tracks as audio files...my situation is editing drum tracks (10) with cuts fades etc and then merging each track...if there is random drifting that is no good for 10 drum tracks...thanks

Why did you not just export Audio as Audio files ? I've had Logic and P.Tools running at my studio for years and never encountered any problems from go back and fourth !

There is no "random drift" that is endemic to the application. Obviously, there was something specific in his situation.

Using WAV as your audiofile format automatically creates "Broadcast WAV" (BWF) files, which are time-stamped. So in Pro Tools (or Nuendo, etc) you can immediately place them exactly where they were in Logic. No issues with drift. So you can either use the Glue (Merge) option, or Export Audio, or even Bounce each track, and it will place flawlessly.

When bouncing through plug-ins with lots of latency, some versions of Logic 7 if I recall pasted some extra silence due to the PDC, but I think that was fixed in a later version of Logic 7. At any rate, it was fixed in Logic 8 for sure.
