Bc2000 (for the BCF2000 & BCR2000)

Hello dear group, 

Im trying to figure out a way to hook up both units but nothing seems to work. Im not sure im using the right midi mode on the bcr2000. My plan is to use it this way:

Ensoniq esq1 (as my master key controller) > BCR2000 > Kawai K4R

Any ideas on how I should route this!?  Thanks a lot!
