Sometimes it helps me to reverse the keypad. Take out the arrow keys and replace up and down, left and right. It makes the keys feel a little easier to reach and press.

Also, try to get used to kind of sliding your fingers instead of picking up your finger between each note (only helps if you play with one hand, might be a little harder to hit fast notes but with some practice you can REALLY impress people) But, these are just my techniques. Try them out but if they dont work try another or develop your own.
