You have to work it your timing a lot. Slow the shit down and get it right before you try increasing the speed
you have to set aside a lot of work to do this as you have already been practicing with ingrained timing problems. You really have to take some time out and fix it! Go slow slow slow with QUARTER NOTES one note per click. ONE NOTE PER CLICK! Then you can increase clicks very gradually up to 200bpm - over a couple months - TRY IT!
