Thanks for that tip loukash. So I doubled down and listened carefully with headphones comparing Mixdown file with the untagged loops. Fortunately the speed and pitch was correct as long as logics transport was running. Got the job done, but I will make dang sure I dont have to do that again. Back in the day HDD drive space was a thing for many of us, and so you came up with work-arounds or compromises, which in the end can cause such issues as this.
Something that happened that Ive never seen before is if I chose the wrong file, the regions in the Main Window showed all white. Bit weird. Another thing that is a real nightmare and theres a thread dedicated to it, is that logic tells you file lengths have changed - real nasty stuff. I've had a few of these in the conversion process, as well as a couple prior, since using Logic 10 - but in my case it was something that could be fixed every time because I was sloppy with naming files. ie LV#01 is not conducive to a good organized filesystem. Do a few of those and you could be in real trouble.
I had the last or nearly the last top end Dual Processor G4, the only one (I think) that had a massive copper heatsink. Ran well with L6 but Im afraid I had to tread carefully with L8. I think I just scraped in on the required specs. It died around 5 years ago. I still have the "Superdrive" but I'd need an IDE >USB adapter to make use of it. I pulled the HDDs and put them in my Linux machine and wrangled my way to find a file I was desperate to find. I had the M-Audio delta 1010. Around the same time my G4 gave up, that went out in sympathy lol. A burned cap.
Your post was the closest to a solution so thanks.
