@xeno3d For the inconsistency with pressure gradation, this is still being worked on.
It's not an easy fix, unfortunately. We're aiming to have further improvements to pressure ETA beginning of next year.
Another thing to try in the meantime -
With the Mac app, hold the Option/alt key when opening Astropad's Preferences.
A Debug tab will show in the window; select that and deselect "Use Adjusted Pressure Curve".
See if this makes a difference at all. Again, thanks for your patience.
