Tapping out of sync

I recently switched from primarily mouse left click to full tapping because my hand decided it couldnt hold a mouse anymore. I was playing mid to high 5 stars and after switching I've been playing high 4 stars and low 5 stars to practice. Problem is with big and small jumps my aim has been extremely out of sync with my tapping except for when I play hard rock. What should I be practicing and doing to help fix this (besides "play more")?
