Hi Ryan,
RG is dead right, but there's a much easier/faster method (might not get such good results though??). Simply edit ENV3 (this one's hardwired to the AMP) and select SOFT VEL CURVE and turn it ON. You can also edit the HARDVEL and SOFTVEL levels (also found in edit ENV3) to get the desired velocity effect.
Hope that's useful,
John
P.S. Nomates at the top should R-T-F-M of not being a P-R-I-C-K. Have a nice day
