Joseluis,
You say you own a Roland E-36. Did you perhaps mean to say Roland E-86? If so, then
I recommend a style converter software program called "KNStyleworks" or "KNWorks Professional" produced by EMC which will convert keyboard styles from most all brands & models of arranger keyboards to the Technics KN5000.
KNStyleworks: DM $298 (german mark)
KNWorks Professional: DM $498 (german mark)
*also includes (standard midi file) song to KN style converter
Works Universal: DM $798 (german mark)
*does all of the above but includes converting to/from ALL brands of arranger keyboards.This is the one I own.
You can purchase the above software from Tastenshop in Germany:
