Kurzweil MicroEnsemble problem

Just received my Kurzweil ME-1 today and I hooked it up to my Roland RD-300 piano. The sustain pedal is not transfered to the ME-1 when I press down on the pedal. I looked in the MIDI implementation chart of both the ME-1 and RD-300 and the ME-1 can receive CC64 and the RD-300 and both receive and send CC64. So I can't understand why the message isn't getting transfered. Any ideas?

I don't know the micro ensemble, but morst kurzweils have three midi settings.
local - midi - both

step 1. choose midi transfer channel
step 2. choose midi since you control the ensemble thru the rd 300.

Hope this helps.
