And yes, I RTFM.
The project tempo is set to the default 120 PBM. But the actual tempo of the material is about 1/2 that I think. I created my MIDI part and input my taps. Since the DAW tempo was 120 and my music is about 60 PBM, I guess I was inputting taps in 2/4 time. No problem. So when I select the “Merge tempo from tapping” option, I select 1/4 notes as my taps. It then always says “Tempo out of range.” And the resulting tempo is half of what it was – quite slow – and my taps aren’t lining up anywhere close to the grid.
I’m not getting how to do this
