you described in the middle region of 16' ...
Or did you really get 10 seconds of beat rate at 8372 Hz ??

My OB-8 takes as long if I don't auto-tune it (I avoid auto-tune).
Same for my CS-50.
My PS-3200 clone takes longer.
Ahh, and my new CS-80 isn't bad, either: I just tried the tuning from last
night with the lid closed, and it seems to be ok after power-on, and after
an hour of having it turned on. (Not _perfect_, but good enough for making
music.)
Seems I've been lucky about the temp code matching. (Haven't checked the
numbers yet - all boards are still inside the frame.)
