Hello. I know this is an old post but if @Scott1 and @DavidScottCole are the same people i have some input about this.
I would imagine you already know this but please see at this thread first Add "Anti-Drift" option for rotating platters
So basically by the nature of spinning motors (and with another bunch of factors) that sends information to the software the timecode isn’t precise like digital. Thus this creates the minor drifts.
But here is the kicker (which is the reason i write to this topic). Op setup includes a “iPhone 14”. Well if this is still true main problem in this case is the “iPhone 14”. Because when i use my “iphone 14 pro max” i also have the bpm all over the place problem so much that it is unusuable.
In that setup i use hercules dj control ultra via bluetooth. And splitter cable for precueing. As you can see I dont have anything that can create any drift besides bluetooth lag that has nothing to with this scenario. Yet i have the same issue with iphone 14 pro max. When i switch to base model apple macbook air m1 same song same transitions, much more effect but no issue at all!
Simultaneous use of bluetooth, Wi-Fi network, limitations of lightning port, bunch of background tasks limits “iphone 14”’s processing capacity. Newer models not only have usb-c port but also a neural engine cores for AI tasks which makes more powerful.
So if you have a chance to try different computer windows desktop or laptop, apple macbook, newer ipad or iphone I would imagine most problems you have will go away besides the natural drift.
