Q:
Can I sync a 44.1k or 48k session to the word clock output of a 192 I/O with a 96k Pro Tools session?
A:
When running a session at 96k the Word Clock output from a 192 I/O will be a derivitive (44.1 or 48) of the sample rate. (so you can clock compatible devices) (SRC)But the AES/EBU output signal from the Digital card on the 192 I/O is not sample rate converted down. Therefore a DAT cannot resolve to the incoming AES/EBU stream. Is this correct? This is correct. Not only would the word clock embedded in the AES/EBU output stream need downsampling, the data would need to be downsampled as well and framed correctly in the new sample rate.Once a 96 kHz session is complete, the whole session should be bounced and then SRC after the bounce. The downsampling algorithms used in the bounce dialog employ downsampling techniques aimed to minimize aliasing when moving between coarse sample rates.

Please locate 'filename.omf' when importing an embedded OMF exported from Avid Express Elite NT into Pro Tools 5.1.3 with Digitranslator 2.0. Session Counter and Big Counter do not reflect accurate SMPTE code. It either clocks the first frame it identifies and stops, gets ahead of or falls behind the clock in the Session Setup window. Pro Tools posts an invalid drive error when reading a session from a LaCie FireWire drive. Apple Drive Setup does not recognize the drive for formatting. When my 1622 is functioning in stand-alone mode, signal routes through the box normally...but when I launch Pro Tools and try and route any of these signals into ANY session at ANY bit depth, there is no activity on the 1622. When launching Pro Tools LE, I get "The current operation could not be completed because no write enable HD was found on the system". |
