@Chregg... Heh. Thanks, man. Tryin' my best here. Slow but sure. ;-)
@Jeff... Hello my friend. This is great info to have in case I encounter old ADAT recordings again. The whole DAW to tape to DAW thing has always bent my brain a bit but the mystery is fading a bit now after this experience and the helpful advice here. Thanks. I hope you've been well.
So here's an update on what's happening. I've been having a heck of a time getting these tracks over to the new system and into Sonar but I think I've got it now. First problem was the old system would get to 99% completion while trying to export an OMF and then it would choke. It created a file though so I tried opening it in X2. No dice. It was corrupt. So then I tried AES31 format which I had never heard of before but in the Nuendo manual it says it's supposed to just export waves that can be used in other DAWS with an option to hang on to fades and volume automation. Well it only created a tiny little file but no audio sooo... no dice. Then I thought I'd try to see if I could do a multitrack export like can be done with Sonar. Only let's you export one track at a time which would take forever and I'm not sure how hard it'd be to sync them all back up. I was thinking that could be a last resort. There was one other option which was "Selected Tracks". This seems to just copy all the waves in the project and put them in a folder. They do sync up so I tried this. Because the project was an hour worth of material broken up into songs I ended up with a huge pile of tracks. One track for each instrument AND for each song. Yikes. I also neglected to change my samplerate in the Sonar project so they overlapped. Big old mess. The final answer seems to be going through the individual waves and selecting the instrument tracks for each one using CTRL select and importing them that way. One other problem I had was I checked off the box that says "import tracks as mono" and was only getting one side. They should be mono tracks but they don't want to playback through the master in stereo. Whatever... I just unchecked that box and now everything is stereo and it seems to be working fine. However listening back I realize some of the actual recording and playing is quite poor but I think the drums and vocals are salvageable which was the most important part for me anyway. The rest I can overdub.
So tl;dr... I've finally managed to figure out how to get this stuff into Sonar so I can work on it. Hooray! Being able to get this project into Sonar has been a major concern of mine for a while now but it looks like I can make it happen.
Cheers, guys and thanks again. Stay awesome.
