DIGI 001 to HD192 Sample Rate plays back wrong...

[Nathan W.]

Hi,

I had this really weird error I've never encountered before. I imported from a firewire drive a live recording made on a Digi001 to my HD192 system using Protool 6.9 to mix. When I opened the session and played it back it was a crappy recording but sounded fine...at first. After I mixed one song I bounced it but when I played it back in iTunes the pitch was completely off; it was shifted downwards. It sounded like ProTools had upsampled my bounce to 48k/16bit for whatever reason. So I went back into ProTools thinking I had accidently converted the file on export to 48/16bit. But when I played back the session the entire session played back too slowly like the entire session at been up-sampled to 48/16bit! So I went to manually force-change the sound files in my workspace windows but it said all my files were at 44.1/16 bit...I tried to actually click on the sample rate but it wouldn't allow me to change it. So I'm completely lost as to what I did and what happened...any clues on what I need to do to fix this?

Thanks!
Nathan

From what you describe, it sounds like a combination of problems.

First of all, there is a very good possibility that the original recording was done, clocked to either the SP/DIF or the ADAT lightpipe input at 48kHz, but the session was created as a 44.1 session. Therefore, when you play the session back (on internal clock), it sounds slow. There is also a possibility that you mixed the first tune, also clocked to something at 48kHz, because you said that it sounded right at first.

The first step is to check your clock setting, and verify that you're on internal clock. If you're using a SYNC I/O, make sure that the VSO is not turned on. Then, if it's still playing back slow, here's what you need to do.

-Create a new ProTools session at 48kHz.

-Import all the tracks into the new session, but in the SRC section, de-select the option for SRC, and let it come into the session as-is. Make sure the new tracks will "Refer" to the original files, rather than "Copy".

If the tracks are playing back correctly, then you've identified the problem. You are free to continue with the session as-is, but eventually you will probably want to consolidate the original files, and remove the old ones from the region bin. Any new files you create will be labelled correctly as 48kHz files.

Hope this helps!
Cheers, eh?
