Transfer SMPTE-sync'd audio to disk
Posted: Thu Oct 24, 2013 2:52 pm
I have a few SMPTE-striped multitrack tapes. I used them with Performer/Mac OS9 (pre and post Digital Performer) and used the SMPTE signal to keep the audio sync'd with MIDI tracks. I used an MTP AV/USB to get the SMPTE into the Mac. I now have a MIDI Express XT for that. I have switched to Windows 7 64bit with Digital Performer 8.
I'd like to record the analog tracks into Digital Performer audio tracks but I am confused about the process. I presume there's a hole in my understanding of synchronization.
It seems like I want to playback the tapes while sync'd to SMPTE and record the audio tracks while doing so. The part I miss is this: when I subsequently playback the newly-digitized audio, the SMPTE clock pulses will be useless because they will stay on the original audio tapes. Presumably, the clock source will be the PCI-424 card that I use for all-digital projects. That won't mimic the SMPTE pulses from the tape exactly. Will that mean the audio will drift relative to the MIDI tracks in the same sequence?
This must be a solved problem; I presume many people have transferred old material from SMPTE-striped tapes to digital audio tracks. It beats me how to solve it.
What am I missing?
