Thanks so much Mario. The purported 33 cents is rumor off of the internet, but not definitive. So what I ended up doing is loading the biab split bass stem track into Reaper, isolating a sustained note and using a desktop tuner to "hear that note looped" via my computer speakers and thus the real cents variance was easily displayed. Interestingly the included tuner plugins in the DAW would not register a note reliably so I had to use this unusual method. Interestingly it was 35 cents flat so the internet info was pretty close. I then just corrected the entire unsplit track in Reaper so I have a track that I can play along with at concert pitch and then do the stem splitting again in biab. I will have to adjust my workflow in biab now to take into account this common finding with old songs. I am transcribing all of the Beatles songs specifically for their bass lines. Their recorded work is all over the place as far as tuning is concerned, likely due to tape machine inaccuracies and mastering/pressing issues. Apparently it is very common. Thanks for helping me; your comments are always so valued!
